Clean Beauty Ingredient Substitutions: The Ultimate Formulation Guide
“The best clean substitution usually isn’t the ingredient that sounds most similar. It’s the ingredient system that replaces the original function without quietly making the product worse.”
The hardest part of making a cosmetic formula "cleaner" is usually not identifying the ingredient a brand wants removed.
It is figuring out everything that ingredient was doing before you took it out.
Dimethicone may be providing slip, barrier properties, spreadability, powder wetting, and afterfeel.
EDTA may appear near the bottom of the ingredient list while quietly supporting preservation, color stability, and resistance to metal-catalyzed oxidation.
Phenoxyethanol may be only one percent or less of the formula, yet replacing it can force changes to pH, packaging, supporting antimicrobial ingredients, and challenge-testing strategy.
A carbomer may look like nothing more than a thickener until replacing it changes clarity, suspension, yield value, tack, electrolyte tolerance, and pumpability.
This is why good clean reformulation is not built around:
REMOVE INGREDIENT A → INSERT INGREDIENT B
It is built around:
IDENTIFY FUNCTION → DEFINE CLEAN STANDARD → SELECT REPLACEMENT SYSTEM → REBALANCE FORMULA → RETEST PERFORMANCE
And there is another complication: clean beauty does not have one universal technical definition.
Different retailers, certification systems, and brands maintain different standards. Ulta Beauty, for example, currently allows phenoxyethanol and permits mineral oil, paraffin, and petrolatum when they meet specified purity requirements, while its Made Without List excludes ingredients including parabens, SLS, SLES, D4, and several other classes. COSMOS takes a different approach based on ingredient origin, processing, green chemistry, and qualification of specific raw materials for natural or organic certification.
So the first question in a clean substitution project should not be:
"What is the clean alternative?"
It should be:
"Clean according to whom, and what does the finished product still need to do?"
There Is No Universal Clean Ingredient List
This is the starting point for almost every clean reformulation project.
"Clean" may mean:
Compliant with a specific retailer
COSMOS-compatible
Natural-origin
Organic-certifiable
Vegan
Petrochemical-free
Silicone-free
PEG-free
Phenoxyethanol-free
Paraben-free
Microplastic-conscious
Biodegradability-focused
Fragrance-free
Aligned with a brand's own ingredient philosophy
These are not interchangeable requirements.
A raw material can be acceptable under one clean framework and excluded under another.
Ulta's current Clean Ingredients program, for example, permits phenoxyethanol and places purity requirements on mineral oil and petrolatum rather than categorically excluding them. Its standards also permit certain ethoxylated ingredients when contamination limits are met.
COSMOS operates very differently. It evaluates ingredient origin and processing and maintains databases of individually approved or certified cosmetic raw materials. Its current database includes thousands of raw materials representing a wide range of ingredient functions.
That means a founder should define the target standard before asking a chemist to reformulate.
Otherwise, the formula may be reformulated twice.
Clean Substitution Is Usually Functional Substitution
An ingredient rarely has only one effect on a formula.
A cosmetic ingredient may function as:
Emollient
Solvent
Humectant
Preservative
Preservative booster
Chelator
Emulsifier
Co-emulsifier
Thickener
Suspension aid
Film former
Surfactant
Foam modifier
Conditioner
Antioxidant
Opacifier
Powder dispersant
Fragrance carrier
pH adjuster
And one ingredient may perform several of those jobs simultaneously.
That creates a common reformulation problem.
A brand says:
"Remove the silicone."
The chemist removes the silicone.
The replacement oil gives acceptable slip.
But the formula now dries more slowly.
The finish becomes greasier.
Powders disperse differently.
Water resistance declines.
The product pills under sunscreen.
Technically, the silicone was replaced.
Commercially, the product may be worse.
A true substitute therefore needs to be evaluated by function and performance, not simply by INCI category.
Silicone Alternatives
Silicone substitution is one of the most common clean-beauty formulation requests.
It is also one of the least likely to produce a perfect one-for-one replacement.
Silicones can provide an unusual combination of:
Low friction
Spreadability
Dry slip
Volatility
Cushion
Water resistance
Film formation
Powder dispersion
Hair conditioning
Reduced tack
Elegant afterfeel
No single plant oil reproduces all of that.
That is why sophisticated silicone-free formulas often use several materials to recreate the sensory architecture previously supplied by one silicone system.
Alternatives to Dimethicone
Depending on what dimethicone is doing, a formulator may consider materials such as:
Coco-Caprylate/Caprate
A lightweight ester frequently used to create fast spread and a relatively dry emollient feel.
It can help replace some of the slip consumers associate with lighter silicones.
It is not chemically or functionally identical to dimethicone.
Isoamyl Laurate
Another light ester that can provide rapid spread and a less oily finish than many conventional vegetable oils.
This can be particularly useful when silicone removal makes a formula feel heavy.
C13-15 Alkane
Certain naturally derived grades of C13-15 Alkane are marketed specifically as lightweight sensory alternatives to volatile silicones.
Their quick spread and dry feel can be useful in skincare, makeup, sunscreen, and haircare.
Hemisqualane-Type Materials
Sugarcane-derived or biotechnology-derived lightweight hydrocarbons can provide elegant slip and rapid spread.
Again, raw-material origin and certification status depend on the specific supplier grade.
Squalane
Squalane can contribute beautiful emolliency and oxidative stability, particularly when sourced from modern plant-derived or fermentation-derived feedstocks.
But it generally behaves more like an emollient oil than a volatile silicone.
Natural-Origin Esters
Esters based on fatty acids and fatty alcohols can be selected for very specific sensory characteristics.
The useful comparison isn't:
ESTER = SILICONE SUBSTITUTE
It is:
Which ester or ester blend reproduces the spread, cushion, volatility, and residual feel we need?
This is why silicone-free sensory formulation can require considerably more experimentation than simply replacing a percentage.
Cyclomethicone and Volatile Silicone Alternatives
Volatile silicones create another problem.
They spread beautifully and then partially evaporate, leaving relatively little oily residue behind.
A fixed plant oil cannot reproduce that behavior.
Potential alternatives may include lightweight alkanes, volatile-like natural-origin emollients, certain esters, or combinations engineered to create a similar application curve.
Current environmental regulation is also influencing this area. D4, D5, and D6 cyclic siloxanes have faced increasing European restrictions based largely on environmental persistence concerns, accelerating interest in alternative sensory systems.
But it is important not to turn that into:
all silicones are bad
or:
all silicone alternatives are automatically better.
Dimethicone and volatile cyclic siloxanes are not the same material.
Environmental profile, sensory behavior, biodegradability, safety, and regulatory status should be considered at the actual ingredient level.
Why Natural Oils Usually Aren't Direct Silicone Replacements
A common reformulation mistake is replacing silicone with:
Jojoba
Sunflower oil
Coconut oil
Meadowfoam oil
Argan oil
These can all be excellent cosmetic ingredients.
They just don't necessarily behave like silicone.
Plant oils can contribute:
Lubricity
Emolliency
Fatty acids
Natural-origin positioning
They can also add:
Greasiness
Oxidation susceptibility
Color
Odor
Heavier residual feel
A sensory replacement should be chosen because it provides the required sensory behavior, not merely because both ingredients are liquids.
Silicone-Free Haircare Is Even Harder
Haircare increases the difficulty.
Silicones may support:
Wet combing
Dry combing
Shine
Reduced friction
Heat protection
Frizz control
Film deposition
Damaged-fiber feel
Reduced static
A lightweight ester that works beautifully in facial skincare may do almost nothing to reproduce the deposition profile of an amodimethicone conditioner.
Silicone-free haircare may require a different conditioning architecture involving combinations of:
Cationic conditioners
Esterquats
Natural-origin conditioning polymers
Fatty alcohols
Lightweight emollients
Film-forming biopolymers
This is why removing silicone from haircare is often a system redesign rather than an oil substitution.
Petrolatum and Mineral Oil Alternatives
Petrolatum and mineral oil are another interesting clean-beauty category because the commercial conversation and toxicological conversation are not always the same.
Highly refined mineral oil and petrolatum remain permitted in many cosmetic frameworks. Ulta's current Clean Ingredients standard, for example, permits mineral oil, paraffin, and petrolatum when they meet specified pharmaceutical-grade purity requirements.
A brand may still choose to exclude them for:
Petrochemical-free positioning
Natural-origin goals
Certification
Consumer preference
Sustainability strategy
That is a brand constraint rather than proof that every permitted refined mineral oil is unsafe.
Alternatives to Mineral Oil
Potential options include:
Squalane
Hydrogenated vegetable oils
Stable plant oils
Coco-Caprylate/Caprate
Dicaprylyl Carbonate
Lightweight esters
Naturally derived alkanes
But performance varies dramatically.
Mineral oil has several technical advantages:
Low odor
Low color
High oxidative stability
Reliable supply
Consistent sensory behavior
Many botanical oils are chemically more complex and more oxidation-prone.
So replacing mineral oil with a vegetable oil can improve one part of the brand story while creating a harder oxidation problem.
That isn't a reason not to do it.
It is a reason to formulate around the consequence.
Alternatives to Petrolatum
Petrolatum provides strong occlusivity and a distinctive semi-solid texture.
Potential alternatives may use combinations of:
Hydrogenated vegetable oils
Plant waxes
Butters
Castor-derived materials
Squalane
Esters
Oleogels
Structuring agents
The challenge is reproducing:
Occlusion
Glide
Cushion
Payoff
Melt profile
Stability
A botanical balm may feel more waxy.
A butter-heavy system may become grainy.
A plant-oil-heavy system may oxidize faster.
A sophisticated petrolatum-free balm therefore usually requires structure engineering, not simply replacing petrolatum with shea butter.
PEG and Ethoxylated Ingredient Alternatives
PEGs and ethoxylated ingredients have been frequent clean-beauty discussion points.
But current retailer policies differ substantially.
Ulta's current Made Without List does not categorically prohibit all ethoxylated ingredients. It permits PEGs and polysorbates when specified contaminant limits for ethylene oxide and 1,4-dioxane are met.
A brand pursuing PEG-free or COSMOS-oriented formulation may still require alternatives.
Polyglyceryl Esters
Polyglyceryl emulsifiers and surfactants have become some of the most useful tools in natural-origin and clean formulation.
Depending on the material, they may support:
Emulsification
Solubilization
Cleansing
Co-emulsification
Sensory modification
Examples of relevant INCI families include:
Polyglyceryl-3 Stearate
Polyglyceryl-6 Distearate
Polyglyceryl-10 Laurate
Polyglyceryl-4 Oleate
This is a broad ingredient family, not a one-size-fits-all substitution.
Glyceryl Stearate Citrate
This can be useful in naturally positioned oil-in-water emulsions.
It often creates a very different texture from a conventional PEG-based emulsifier.
That may be desirable.
Or not.
The point of reformulation is not to prove the clean alternative can make an emulsion.
It is to make the right emulsion.
Sucrose Esters
Sucrose-based emulsifiers can create elegant natural-origin systems but may have specific processing, viscosity, electrolyte, and sensory considerations.
They should be chosen because they fit the complete formula rather than because "sugar-based emulsifier" sounds attractive.
Lecithin and Phospholipids
Lecithin-derived systems can provide emulsification and lamellar-structure opportunities.
They can also introduce:
Color
Odor
Oxidation sensitivity
Processing complexity
Again, natural origin doesn't remove formulation consequences.
Sulfate Surfactant Alternatives
Sulfate-free cleansing is now so common that many consumers assume sulfates were simply replaced with gentler versions of the same thing.
In practice, cleanser architecture changes considerably.
Ulta's current Clean Ingredients Made Without List excludes both Sodium Lauryl Sulfate (SLS) and Sodium Laureth Sulfate (SLES) from qualifying products.
Brands seeking sulfate-free cleansing may use combinations drawn from several surfactant families.
Alkyl Polyglucosides
Common examples include:
Decyl Glucoside
Coco-Glucoside
Lauryl Glucoside
These are widely used in natural-origin cleansing systems.
They can produce useful foam and cleaning performance.
But APGs can also create formulation challenges involving:
High supplied pH
Viscosity
Skin feel
Foam character
Eye comfort
Interaction with other surfactants
"Glucoside" does not automatically mean milder in every finished formula.
Concentration and surfactant architecture still matter.
Amino Acid Surfactants
Examples include glutamate-based surfactants such as:
Sodium Cocoyl Glutamate
Disodium Cocoyl Glutamate
These can create very elegant mild-cleansing systems.
They may cost more than commodity surfactants and behave differently in foam and viscosity development.
Isethionates
Ingredients such as Sodium Cocoyl Isethionate have become especially popular in bars and creamy cleansing systems.
They can provide rich foam and attractive skin feel.
They are not simply liquid drop-in replacements for SLES.
Physical form, processing, solubility, and product architecture differ.
Why Sulfate-Free Cleansers Sometimes Feel Worse
A surfactant does more than remove oil.
The surfactant system affects:
Foam volume
Foam density
Rinse
Afterfeel
Viscosity
Fragrance solubilization
Preservative behavior
Removing SLES may cause the product to lose the exact foam consumers associate with cleanliness.
The replacement system may also refuse to thicken with the same salt curve used in the original formula.
This is why sulfate-free reformulation often requires rebuilding the surfactant blend rather than replacing SLES gram for gram.
Carbomer and Synthetic Rheology Modifier Alternatives
Carbomers are extremely efficient rheology modifiers.
At relatively low levels, they can create:
Clear gels
Yield value
Suspension
Elegant flow
Broad viscosity control
A formula designed without carbomer can absolutely work.
But natural gums do not behave identically.
Xanthan Gum
Xanthan is one of the most useful natural-origin rheology modifiers in cosmetics.
COSMOS currently lists approved commercial raw materials based on xanthan and related gums.
Advantages can include:
Broad pH utility
Good suspension
Natural-origin compatibility
Electrolyte tolerance relative to some synthetic systems
Challenges can include:
Stringiness
Tack
Less elegant break
Reduced clarity
Characteristic gum texture
The right level can be tiny and still materially alter skin feel.
Sclerotium Gum
Sclerotium Gum can produce a softer, more elegant feel in certain systems.
It is also represented among current COSMOS-approved commercial raw materials.
It may be combined with other gums to create better sensory balance.
Cellulose-Derived Rheology Modifiers
Depending on the clean standard, cellulose-based polymers can provide useful thickening and stabilization.
Potential functions include:
Viscosity
Suspension
Film
Texture modification
Again, the exact derivative and certification status matter.
Starches
Modified or native starch systems can provide:
Thickening
Powdery afterfeel
Oil control
Sensory modification
They may also influence:
Rub-out
Whiteness
Drag
Stability
Microbial strategy
Why Gum Stacking Can Go Wrong
If carbomer is removed, a common instinct is to add several natural gums.
That can solve viscosity while destroying sensory quality.
The resulting formula may become:
Slimy
Stringy
Sticky
Rubbery
Difficult to pump
Prone to pilling
A viscosity number alone does not describe rheology.
A 20,000 cP carbomer gel and a 20,000 cP xanthan gel can feel completely different.
This is a classic example of why substitution by specification alone can fail.
EDTA Alternatives
EDTA is not a glamorous ingredient.
It is also a good example of why tiny functional ingredients matter.
Chelators bind metal ions that might otherwise contribute to:
Oxidation
Color change
Fragrance deterioration
Preservative interference
Instability
Removing EDTA because it appears on an exclusion list and adding nothing back can weaken several parts of the formula at once.
Phytic Acid and Sodium Phytate
Phytic Acid and Sodium Phytate are common clean and natural-origin chelation options.
Current COSMOS-approved raw-material listings include Phytic Acid-based materials.
They can be useful in skincare and haircare systems, particularly where natural-origin positioning matters.
But chelators differ in:
Metal-binding profile
Effective pH range
Compatibility
Strength
A direct one-to-one percentage substitution should not be assumed.
Glutamate-Derived Chelators
Materials based on glutamic-acid chemistry can also provide biodegradable chelation options.
Again, the exact commercial raw material should be evaluated against the target certification and formula.
Why Chelation Can Affect Preservation
Preservative systems don't operate in isolation.
Metal ions can interact with formulas in multiple ways, and chelation can support overall robustness.
A reformulator replacing EDTA should therefore evaluate not only oxidation but also the preservation strategy.
This is one reason seemingly minor clean substitutions can lead to unexpected challenge-test results later.
Phenoxyethanol Alternatives
Preservation may be the most important area where clean substitutions should never be treated casually.
Phenoxyethanol is widely used because it offers broad utility across many cosmetic systems.
It is also not universally excluded from clean standards.
Ulta's current Clean Ingredients framework explicitly allows phenoxyethanol at 1% or below.
Other brands and retailer philosophies may require phenoxyethanol-free formulas.
That is perfectly workable.
But removing it changes the preservation strategy.
Organic Acid Preservation
Potential systems may involve ingredients such as:
Sodium Benzoate
Potassium Sorbate
Benzoic Acid
Sorbic Acid
These can be useful, particularly in appropriately acidic formulas.
The phrase appropriately acidic matters.
Organic-acid preservation is highly pH dependent.
If the formula contains actives that prefer a different pH, the preservation decision can affect the entire product architecture.
Benzyl Alcohol-Based Systems
Benzyl Alcohol may appear in preservation blends, sometimes combined with materials such as Dehydroacetic Acid.
Whether the system meets a brand's clean requirements depends on the exact standard and raw material.
It also brings its own odor, sensitization, pH, and compatibility considerations.
Multifunctional Preservation Support
Modern preservation frequently uses ingredients that perform more than one job.
Examples may include materials based around:
Glyceryl Caprylate
Caprylyl Glycol
1,2-Hexanediol
Certain organic acids
Aromatic alcohols
Chelating systems
Some function as antimicrobial boosters rather than complete stand-alone preservation systems.
This distinction matters.
A formula containing several "preservative alternative" ingredients is not automatically adequately preserved.
Ferment-Based Preservative Systems
Ferment-derived antimicrobial materials have strong clean-beauty appeal.
They can be useful in the right system.
But the word ferment should not be confused with guaranteed broad-spectrum preservation.
The complete formula still has to prove that it can resist microbial challenge.
The Preservative Is Not the Place for Ideology to Replace Testing
If a founder wants:
Phenoxyethanol-free
Paraben-free
Organic-compatible
Ferment-preserved
Sensitive-skin
Minimalist
those can all be legitimate product-development constraints.
The answer is not to argue with the brief.
The answer is to design the strongest preservation system possible within it and verify that system.
A clean preservative strategy may require more coordination among:
pH + chelation + packaging + water activity + multifunctionals + primary preservative system
than a conventional formula.
That is why Preservative Efficacy Testing, or PET, remains so important.
"Natural preservative" is a sourcing description.
It is not a microbiological result.
Paraben Alternatives
Parabens remain another area where consumer perception, retailer requirements, and ingredient safety discussions are often mixed together.
Many clean programs exclude them, including Ulta's current Made Without List.
A brand targeting those channels therefore needs a paraben-free system regardless of the broader toxicological debate.
Alternatives may involve:
Phenoxyethanol-containing systems
Organic acids
Benzyl alcohol systems
Multifunctional antimicrobial blends
Other globally permitted cosmetic preservatives
But replacing a paraben system can change more than antimicrobial efficacy.
Preservatives interact with:
Emulsion phases
Surfactants
Packaging
pH
Solubility
Rheology
This is why reformulating a successful preserved product can take substantially more work than the ingredient list suggests.
Synthetic Antioxidant Alternatives
Ingredients such as BHA and BHT may be targeted in certain clean standards.
Again, current standards differ.
Ulta currently excludes BHA while permitting BHT up to a specified maximum of 0.05%.
Potential alternative antioxidant systems may include:
Tocopherol
Mixed tocopherols
Rosemary-derived antioxidant extracts
Ascorbyl Palmitate
Other oil-phase antioxidant technologies
But antioxidants differ in:
Phase preference
Radical chemistry
Stability
Color
Odor
Tocopherol is not a universal gram-for-gram substitute for BHT.
A natural-origin antioxidant system may require a combination of materials.
And antioxidants should not be confused with preservatives.
Protecting an oil from rancidity does not protect a water-containing lotion from microbial growth.
Synthetic Fragrance Alternatives
"Natural fragrance" sounds like the obvious clean alternative to synthetic fragrance.
It isn't necessarily the obvious formulation alternative.
A brand actually has several strategic choices:
Fragrance-Free
Often the cleanest technical route for sensitive-skin positioning.
It also leaves the natural odor of the raw materials exposed.
Natural Fragrance
Can fit natural-origin positioning when appropriately sourced and documented.
But natural fragrance ingredients can still contain allergens and sensitizing constituents.
Essential Oils
Can provide beautiful olfactory profiles and strong botanical storytelling.
They can also introduce:
Allergens
Oxidation
Photosensitivity concerns for certain materials
Color
Solubility problems
Regulatory limits
Natural origin does not make an aromatic molecule biologically invisible.
Sometimes Synthetic Fragrance Is the More Controlled Option
This is uncomfortable for simplistic clean-beauty narratives but technically important.
A carefully constructed fragrance can sometimes reduce reliance on certain naturally occurring allergenic fragrance constituents compared with an essential-oil-heavy approach.
That does not mean synthetic fragrance is universally better.
It means:
natural vs. synthetic is not the same question as irritating vs. non-irritating.
For sensitive-skin products, fragrance-free may be a more meaningful decision than arguing over fragrance origin.
Microbead and Synthetic Exfoliant Alternatives
Environmental restrictions have made plastic microbeads a much less relevant cosmetic option than they once were.
Potential physical exfoliant alternatives may include:
Hydrated Silica
Cellulose particles
Jojoba-derived beads
Wax particles
Mineral exfoliants
Plant-derived powders
COSMOS currently lists numerous Hydrated Silica raw materials among approved cosmetic ingredients.
But exfoliation quality depends heavily on:
Particle size
Shape
Hardness
Concentration
Product format
A natural seed powder can sound appealing and still create a harsher scrub than a carefully engineered synthetic particle.
"Natural exfoliant" does not automatically mean "gentle exfoliant."
Synthetic Film Former Alternatives
Film formers are especially important in:
Sunscreen
Makeup
Haircare
Long-wear skincare
Water-resistant products
Replacing synthetic acrylate or silicone film-forming systems can be technically difficult.
Natural-origin options may include certain:
Polysaccharides
Pullulan systems
Cellulose derivatives
Gums
Protein-derived films
Bio-based polymer technologies
The challenge is performance.
A film former may control:
Water resistance
Transfer resistance
Wear
Flexibility
Tack
Shine
Pigment adhesion
Replacing it because a clean standard excludes the original polymer can materially change the product.
This is one of the areas where performance testing matters more than an ingredient substitution list.
A lipstick that is 100% compliant but transfers onto every glass is not an equivalent reformulation.
Clean Emulsifier Substitution Is an Architecture Change
Emulsifier swaps deserve special attention because founders often underestimate them.
The emulsifier affects much more than whether oil and water stay mixed.
It can influence:
Viscosity
Droplet structure
Skin feel
Soaping
Cushion
Absorption
Electrolyte tolerance
Active compatibility
Scale-up behavior
Changing from a PEG-containing emulsifier to a natural-origin emulsifier can therefore change the personality of the entire product.
Sometimes that creates a better formula.
Sometimes it creates a formula that is technically stable but feels nothing like the benchmark.
That means the goal during reformulation should usually be:
REBUILD THE TARGET SENSORY EXPERIENCE
rather than:
MAKE THE NEW EMULSIFIER BEHAVE LIKE THE OLD ONE AT THE SAME PERCENTAGE
Why Ingredient Substitutions Cause Unexpected Stability Failures
A formula is an equilibrium of interacting materials.
Change one and you may change several properties simultaneously.
For example, a new emulsifier may alter:
Interfacial structure
pH
Viscosity
Preservative partitioning
A new ester may alter:
Oil-phase polarity
Solubility of actives
Fragrance behavior
A new gum may alter:
Water availability
Suspension
Pumpability
Sensory feel
A new preservative may alter:
pH
Viscosity
Emulsion stability
Odor
The original ingredient may have been supporting the product in ways nobody noticed until it disappeared.
This is why clean reformulation requires stability testing even when every replacement ingredient is individually well understood.
A Clean Reformulation Should Usually Be Treated as a New Formula
This may be the most useful rule in the entire guide.
If a formula undergoes meaningful changes to:
Emulsifier
Preservative
Surfactant system
Rheology
Oil phase
Film former
Chelator
I would not assume the old stability and preservation conclusions automatically transfer.
The product may need renewed evaluation of:
Stability
PET
Packaging compatibility
pH
Viscosity
Sensory performance
Claims
Manufacturing behavior
A reformulation can look 90% identical on an INCI list while behaving differently enough to require real redevelopment.
The Percentage Often Needs to Change Too
Ingredient substitution is especially misleading when performed on a percentage basis.
Suppose the original formula contains 0.3% carbomer.
That does not mean:
0.3% xanthan gum = natural replacement
Likewise:
1% dimethicone does not mean 1% ester.
0.1% EDTA does not mean 0.1% sodium phytate.
1% phenoxyethanol blend does not mean 1% organic-acid system.
5% mineral oil does not mean 5% sunflower oil.
Different ingredients have different:
Efficiency
Molecular behavior
Active concentration
Carriers
Sensory effects
Recommended use ranges
A substitution should preserve function, not arithmetic.
Raw-Material Percentage Can Hide the Real Composition
This becomes particularly important with modern clean ingredient blends.
A formulator may use:
3% of a natural preservative blend
but that blend may itself contain several ingredients at defined ratios.
Or:
5% of a silicone-alternative emollient technology
may contain multiple esters.
Or:
2% of a green emulsifier blend
may contain the emulsifier, fatty alcohol, and stabilizing co-emulsifier.
The percentage of the commercial raw material is not necessarily the percentage of the ingredient being highlighted.
This is another reason brands benefit from understanding the quantitative formula and the supplier raw materials behind it.
"Natural" Can Increase Formula Complexity
There is a persistent assumption that natural formulation should be simpler.
It often isn't.
Replacing one highly efficient conventional ingredient may require two or three natural-origin ingredients.
A silicone sensory package may become:
Lightweight ester
Alkane
Squalane
A preservative may become:
Organic acid
Multifunctional booster
Chelator
pH strategy
A synthetic polymer may become:
Xanthan
Sclerotium
Starch
The resulting INCI can actually become longer.
That doesn't mean the reformulation failed.
It means highly optimized conventional materials can sometimes perform several jobs at once.
Clean formulation frequently redistributes those jobs across a broader system.
Clean Does Not Automatically Mean Biodegradable
Another distinction worth making.
The following ideas are related but not identical:
Clean
Natural
Natural-origin
Organic
Bio-based
Biodegradable
Renewable
Sustainable
COSMOS-compatible
An ingredient can be bio-based without being readily biodegradable.
A natural ingredient can carry significant agricultural impact.
A biodegradable ingredient may not qualify for a particular organic certification.
A fermentation-derived ingredient can be highly sustainable while not fitting someone's intuitive idea of "natural."
COSMOS explicitly incorporates sourcing, responsible natural-resource use, processing, and green chemistry into its standard rather than reducing qualification to whether an ingredient came from a plant.
This is where Clean Beauty 2.0 becomes more useful than old "synthetic vs. natural" thinking.
Clean Beauty 2.0 Is About Constraints Plus Performance
The first generation of clean beauty was largely defined by exclusion.
No parabens.
No silicones.
No sulfates.
No mineral oil.
No PEGs.
No synthetic fragrance.
Those preferences still matter to many consumers and brands.
But product development now has to ask the second question:
What are we replacing them with, and is the finished product actually better?
A modern clean formula should ideally balance:
Ingredient philosophy
Safety
Preservation
Stability
Sensory quality
Environmental considerations
Consumer expectations
Commercial viability
A "clean" moisturizer that separates at six months is not a better moisturizer.
A sulfate-free shampoo consumers hate using is not commercially improved.
A preservative-free serum that fails microbial testing is not safer because the ingredient list looks shorter.
Performance is part of responsible formulation.
Sometimes the Conventional Ingredient Is Already Allowed
Before spending months replacing something, confirm whether removal is actually required.
This sounds obvious.
It frequently isn't.
Current clean programs can be more nuanced than their reputation suggests.
Ulta currently allows phenoxyethanol within its stated limit, certain ethoxylated ingredients subject to contamination criteria, and high-purity mineral oil and petrolatum.
COSMOS qualification works through specific raw-material origin and processing criteria rather than a generic internet blacklist.
A brand might discover that the ingredient it planned to replace is acceptable for the actual retailer or certification target.
That can save:
Development time
Stability risk
COGS
Sensory compromise
Clean formulation should be intentional.
Not reflexive.
The Best Substitute May Be a Supplier Technology, Not an INCI
This is one of the most important shifts in modern formulation.
A founder may ask for:
"a natural silicone alternative."
There are dozens of possible INCI ingredients.
What often matters more is the specific supplier grade.
Two raw materials with the same INCI may differ in:
Feedstock
Purity
Manufacturing
Sensory profile
Oxidative stability
Certification
Documentation
Carbon footprint
Biodegradability
Cost
Supply reliability
COSMOS itself maintains qualification at the commercial raw-material level, illustrating why supplier-specific documentation matters in certification-oriented formulation.
The INCI tells you the identity.
The supplier technology tells you much more about how it may behave commercially.
Sensory Equivalence Is Often Harder Than Chemical Equivalence
A chemist may be able to make a formula stable after a clean substitution relatively quickly.
Making it feel the same may take longer.
Consumers notice:
First slip
Playtime
Cushion
Drag
Absorption
Tack
Powderiness
Greasiness
Residue
Afterfeel
They may not know why the formula changed.
They only know the new version no longer feels as expensive.
This matters enormously in reformulation.
A clean ingredient decision that reduces sensory quality can reduce repurchase even if the consumer theoretically prefers the ingredient list.
Ingredient philosophy and sensory performance need to coexist.
Manufacturing Can Expose Problems the Lab Did Not
Natural gums, waxes, emulsifiers, and botanical systems can behave differently during scale-up.
Potential differences can appear in:
Hydration
Heating
Cooling
Shear
Aeration
Transfer
Filling
Final viscosity
A natural-emulsifier cream that behaves perfectly at 500 grams may require process adjustment at commercial scale.
A gum system may hydrate differently.
A waxy balm may cool differently.
A sulfate-free cleanser may build viscosity differently.
Clean reformulation is not finished when the laboratory sample looks good.
The formula still has to become a repeatable commercial product.
Packaging Can Become Part of the Substitution
Removing an ingredient can sometimes change the best packaging choice.
A more oxidation-prone botanical oil system may benefit from better oxygen protection.
A weaker preservation architecture may favor an air-restrictive pump over an open jar.
A higher-gum formula may require a different pump.
A natural balm may soften more under heat and require different component testing.
This is why packaging compatibility should be reevaluated after meaningful reformulation.
The old bottle is not automatically the right bottle for the new formula.
"Free From" Claims Should Match the Actual Supply Chain
If a brand wants to claim:
Silicone-free
PEG-free
Petrochemical-free
Phenoxyethanol-free
Microplastic-free
it needs to evaluate more than the obvious main ingredients.
Supplier blends can contain:
Preservatives
Carriers
Processing aids
Supporting ingredients
A botanical extract marketed by its plant name might be supplied in phenoxyethanol.
A proprietary active may be delivered in a PEG-containing carrier.
A fragrance may introduce components the brand did not anticipate.
This is why complete raw-material composition matters during claims development.
The front of the package should not be designed before the raw-material documentation is understood.
Clean Substitution by Category
A useful way to think about common reformulation targets is this:
If Removing Silicones
First determine whether you are replacing:
Slip
Volatility
Film
Conditioning
Water resistance
Powder dispersion
Then build the alternative around those specific functions.
If Removing Mineral Oil or Petrolatum
Determine whether you need:
Emolliency
Occlusion
Structure
Oxidative stability
Glide
Plant oils alone may not solve all five.
If Removing PEG Emulsifiers
Expect changes in:
Emulsion structure
Viscosity
Sensory profile
Processing
Polyglyceryl, sucrose, glyceryl citrate, lecithin, and other natural-origin systems may be relevant depending on the product.
If Removing Sulfates
Rebuild the surfactant blend around:
Cleansing
Foam
Mildness
Viscosity
Rinse
rather than replacing SLES with one glucoside.
If Removing Carbomer
Rebuild rheology around:
Viscosity
Yield
Suspension
Flow
Skin feel
rather than matching only the cP measurement.
If Removing EDTA
Replace the chelation function.
Phytate- and glutamate-derived options may be relevant depending on the formula and target standard.
If Removing Phenoxyethanol or Parabens
Redesign the preservation system around:
pH
Chelation
Multifunctionals
Packaging
Water availability
Challenge testing
This is one substitution where "close enough" is not good enough.
When a Clean Substitution Makes the Product Better
Reformulation is not always compromise.
Sometimes the constraint produces a genuinely better product.
Replacing a heavy emollient system may lead to a lighter sensory architecture.
A modern polyglyceryl emulsifier may create a more beautiful lamellar cream.
A sulfate-free surfactant blend may improve afterfeel.
A fermentation-derived ingredient may improve supply consistency.
A more robust antioxidant system may extend sensory shelf life.
A clean brief can force the development team to reconsider assumptions that have been sitting in the formula for years.
Constraints can create innovation.
The important thing is not to confuse change with improvement until the product proves it.
When the Clean Substitution Makes the Product Worse
This also happens.
Common consequences include:
Shorter shelf life
Higher tack
Greasier skin feel
Lower foam
Poorer rinse
Weaker water resistance
Worse pigment dispersion
Increased odor
Greater color drift
Higher COGS
More supplier dependencies
More difficult manufacturing
Weaker preservation
A brand should know these trade-offs before committing to an absolute exclusion standard.
Sometimes the trade-off is worth it.
Sometimes another ingredient strategy produces a better balance.
And sometimes the ingredient being removed was not actually incompatible with the brand's target retailer in the first place.
Natural Does Not Mean Risk-Free
This point should be handled without swinging into anti-clean rhetoric.
Botanical and natural-origin ingredients can be excellent.
They can also contain:
Fragrance allergens
Natural color
Oxidation-prone lipids
Variable phytochemicals
Trace contaminants
Agricultural variability
Synthetic ingredients can be:
Highly purified
Consistent
Efficient
Stable
They can also create sustainability, persistence, sourcing, or consumer-perception concerns depending on the material.
The useful question isn't:
Which origin is morally superior?
It is:
Which ingredient best satisfies the brand philosophy, performance target, safety requirements, environmental goals, and commercial reality of this product?
That is a formulation question.
Natural Fragrance Is a Good Example of the Problem
Imagine a brand removes synthetic fragrance because it wants a "cleaner" product.
It replaces the fragrance with a blend of essential oils.
The label now sounds more botanical.
But the new scent may introduce naturally occurring fragrance allergens and may oxidize differently.
The product is unquestionably more natural in one sense.
Whether it is better for a sensitive-skin consumer is another question.
Clean formulation improves when we stop using one adjective to answer several unrelated questions.
The Same Is True of Preservatives
A ferment-derived preservation ingredient may sound more natural than phenoxyethanol.
That does not tell us which system controls microorganisms better in the finished formula.
The only useful answer comes from testing the complete product.
Clean beauty and microbiology have to coexist.
No marketing philosophy changes what bacteria, yeast, and mold require to grow.
Clean Reformulation Should Start With the Consumer
Before changing the ingredient list, define the product.
Who is it for?
Where will it be sold?
What matters to that consumer?
Which exclusions are commercially meaningful?
What sensory attributes are non-negotiable?
What claims matter?
What shelf life is required?
What price point must the formula support?
These questions can dramatically change the substitution strategy.
A $90 prestige moisturizer has a different sensory requirement from a $15 body lotion.
A natural-certified facial oil has a different framework from a Clean at Retailer gel cream.
A sensitive-skin product may prioritize fragrance removal more heavily than silicone removal.
The ingredient strategy should follow the product strategy.
Clean Reformulation Should Not Become Ingredient Bingo
There is a temptation to make the formula look increasingly clean by stacking every fashionable alternative.
Silicone-free.
PEG-free.
Sulfate-free.
Phenoxyethanol-free.
Petrolatum-free.
EDTA-free.
Synthetic-polymer-free.
Fragrance-free.
Natural.
Vegan.
Biodegradable.
Organic.
Each constraint may be individually reasonable.
Together, they can dramatically narrow the formulation toolbox.
That can increase:
Cost
Development time
Stability risk
Preservation difficulty
Supplier dependence
Manufacturing complexity
A good clean brief therefore prioritizes.
Which constraints define the brand?
Which are retailer requirements?
Which are consumer expectations?
Which are scientifically or environmentally important to the company?
And which were added because competitors happened to put them on a "free from" list?
Not every exclusion has equal strategic value.
The Cleanest Formula May Be the One With Fewer Hero Claims
Another consequence of clean reformulation is active overload.
A brand may think:
If we removed several conventional ingredients, we need more botanical actives to make the formula exciting.
So the new version gets:
Green tea
Aloe
Turmeric
Mushroom extract
Seaweed
Ferments
Adaptogens
Ten plant extracts
Now the formula has:
More color
More odor
More electrolyte load
More preservation complexity
More sourcing risk
More claims to explain
A simpler clean formula with fewer, better-characterized technologies may be more sophisticated.
Clean Beauty 2.0 should not mean more botanicals.
It should mean more intentional formulation.
Private Label vs. Custom Clean Reformulation
Private label can be an efficient path when a brand needs:
Speed
Lower development investment
An existing clean platform
Established manufacturing
That can be a very good business decision.
The limitation is control.
If a private-label formula uses an ingredient the brand later decides to exclude, the supplier may not be willing to rebuild the system.
Custom formulation becomes more valuable when the brand needs precise control over:
Ingredient exclusions
Certification
Preservative strategy
Emulsifier architecture
Sensory profile
Hero ingredient percentages
Packaging interaction
Retailer requirements
The difference is not that private label is bad.
It is that custom formulation gives the brand more control when the ingredient philosophy itself is part of the product architecture.
Formula Ownership Matters More When the Ingredient Standard Evolves
Clean standards change.
Retailers update their lists.
New raw materials become available.
Environmental regulations evolve.
Consumer expectations change.
A brand that owns its quantitative formula has much greater ability to respond.
It can know:
Which raw materials are actually present
Exact percentages
Supplier grades
Carrier systems
Which ingredient performs which function
If a future retailer excludes an ingredient, the brand can identify exactly where it appears and what has to be rebuilt.
If a new natural-origin silicone alternative launches, the brand can evaluate it.
If a preservative supplier discontinues a blend, the formula can be modified.
If certification requirements change, the quantitative architecture can be reviewed.
That is where formula ownership creates long-term value.
Ownership of the Formula Does Not Mean Ownership of Supplier Technology
This distinction still matters.
A brand may own a formula containing a patented emulsifier, proprietary preservative blend, or trademarked silicone-alternative technology.
Ownership of the finished quantitative formula does not automatically transfer ownership of:
Supplier patents
Trademarks
Proprietary raw-material composition
Manufacturing technology
What the brand owns is the quantitative architecture of its finished product according to its development agreement.
That still creates substantial strategic control.
A Better Way to Approach a Clean Substitution Project
The most efficient sequence is usually:
1. DEFINE THE STANDARD
Retailer, certification, internal brand philosophy, or all three.
2. IDENTIFY THE TRUE TARGET INGREDIENTS
Do not remove materials that are already permitted unless the brand has another reason.
3. IDENTIFY EACH INGREDIENT'S FUNCTION
Determine what the formula will lose when it disappears.
4. BUILD THE REPLACEMENT SYSTEM
This may involve one ingredient.
It may involve three.
5. REBALANCE THE FORMULA
The substitution may affect the rest of the system.
6. EVALUATE SENSORY PERFORMANCE
A technically stable product can still be commercially inferior.
7. RETEST STABILITY AND PRESERVATION
Meaningful reformulation deserves meaningful verification.
8. REEVALUATE PACKAGING AND SCALE-UP
The new formula may not behave like the old one.
That is clean reformulation.
It is much closer to product development than ingredient swapping.
The Commercial Opportunity in Clean Beauty Has Changed
Simply saying:
clean
is no longer much differentiation.
Consumers increasingly expect clean brands to perform as well as conventional products.
Retailers also define their own standards more precisely, while natural and organic certification systems such as COSMOS provide formal frameworks for brands that want a more structured approach.
The next generation of clean products therefore has to compete on:
Sensory performance
Efficacy
Stability
Packaging
Ingredient transparency
Sustainability
Product differentiation
The exclusion list becomes the baseline.
The product still has to earn the repurchase.
Clean Beauty Is Not Dead. It Is Growing Up.
The most useful evolution in clean beauty is moving away from:
synthetic = bad
and:
natural = good
toward more specific questions.
What is the ingredient?
Why is it used?
What does the evidence say?
How is it manufactured?
Does it persist environmentally?
Can biotechnology provide a better route?
What replaces it?
Does the replacement actually work?
What happens to the finished product?
That is a much harder conversation.
It is also a much more useful one.
Clean formulation doesn't become less meaningful when we acknowledge trade-offs.
It becomes more credible.
Key Takeaways
There is no single universal definition of clean beauty. Retailers, certification systems, and brands use different standards.
Successful ingredient substitution begins by identifying function, not simply selecting another ingredient with a cleaner reputation.
One conventional ingredient may require several alternatives to replace its complete sensory or technical role.
Silicone-free formulation frequently requires a blend of esters, alkanes, emollients, polymers, or conditioning materials rather than one direct replacement.
Plant oils do not automatically reproduce mineral oil, petrolatum, or silicone performance.
Polyglyceryl esters, sucrose-derived emulsifiers, lecithin systems, and other natural-origin technologies can replace some PEG-containing emulsifier functions, but the emulsion usually needs to be redesigned.
Sulfate-free cleansing requires rebuilding foam, mildness, viscosity, and rinse, not simply replacing SLES with a glucoside.
Xanthan, sclerotium, cellulose, and starch systems can replace some synthetic-polymer functions, but the rheology and sensory profile will be different.
EDTA removal should include a replacement chelation strategy when chelation is functionally important.
Phenoxyethanol-free preservation is possible, but the replacement system may depend much more heavily on pH, chelation, packaging, and multifunctional ingredients.
"Natural preservative" does not mean the finished product is adequately preserved. PET remains the meaningful test.
Natural fragrance and essential oils are not automatically less irritating than synthetic fragrance.
A substitution should preserve function, not percentage. Equal percentages of two different materials do not imply equivalent performance.
Meaningful clean reformulation should generally be treated as a new stability, packaging, preservation, and scale-up event.
A compliant formula that performs worse is not necessarily a better product.
Clean Beauty 2.0 is strongest when ingredient philosophy and finished-product performance are treated as equally real design constraints.
Formula ownership becomes especially valuable as retailer standards, certification requirements, and ingredient technologies evolve.
Cosmeta's Perspective
I actually think clean formulation gets much more interesting once we stop pretending there is a perfect "natural substitute" for every conventional ingredient.
Sometimes there is.
Sometimes the alternative is better.
Sometimes one ingredient has to become three.
And sometimes the conventional ingredient was doing its job extraordinarily well, so the challenge isn't finding something chemically similar. The challenge is rebuilding the performance without it.
That's where formulation starts becoming creative.
Silicone-free should not mean greasy.
Sulfate-free should not mean bad foam.
Phenoxyethanol-free should not mean fragile preservation.
Natural should not mean unstable.
Clean should not mean consumers have to accept a worse product because the ingredient list looks prettier.
I also don't think clean beauty needs to abandon ingredient exclusions to become more scientifically sophisticated.
Brands are allowed to have an ingredient philosophy.
Retailers are allowed to create standards.
Consumers are allowed to care about sourcing, processing, environmental persistence, petrochemicals, natural origin, or certification.
The chemist's job is to understand the constraint and design intelligently inside it.
That is what I think Clean Beauty 2.0 should become.
Not fewer rules.
Better formulation within the rules that actually matter to the product.
Ready for the Next Step
If a formula needs to become cleaner, start by defining what clean means for the brand and where the product needs to be sold.
Then identify what each targeted ingredient is actually contributing before removing it.
The strongest reformulations don't merely produce a cleaner ingredient list.
They preserve, or improve, the product consumers wanted in the first place.
FAQs
-
There is no universal silicone replacement because silicones can provide slip, volatility, film formation, water resistance, powder dispersion, conditioning, and barrier properties. Depending on the function, formulators may use lightweight esters such as Coco-Caprylate/Caprate or Isoamyl Laurate, naturally derived alkanes, squalane, hemisqualane-type materials, film formers, or combinations of several ingredients. The best replacement depends on what the original silicone was doing.
-
Phenoxyethanol-free preservation may use organic acids and their salts, benzyl-alcohol-based systems, multifunctional antimicrobial ingredients, ferment-derived technologies, chelators, or combinations of these. The appropriate system depends heavily on pH, water activity, packaging, and the complete formula. A phenoxyethanol-free product still needs appropriate preservative efficacy or challenge testing to demonstrate that the finished system is adequately preserved.
-
Xanthan Gum, Sclerotium Gum, certain cellulose-derived polymers, starches, and blended natural-origin rheology systems can replace some carbomer functions. They do not behave identically. A natural gum system may produce more tack, stringiness, opacity, or a different flow profile even when the measured viscosity matches the carbomer formula. The rheology system therefore usually needs to be redesigned rather than swapped one-for-one.
-
It depends on the clean standard. There is no universal clean-beauty rule excluding mineral oil. For example, Ulta Beauty's current Clean Ingredients program permits mineral oil, paraffin, and petrolatum when they meet specified pharmaceutical-grade purity requirements. Other brands or certification frameworks may exclude petrochemical-derived materials for different reasons. Always formulate against the actual target standard rather than a generic clean-beauty blacklist.
-
No. Natural origin and safety are different questions, just as natural origin and performance are different questions. Botanical oils can oxidize, essential oils can contain fragrance allergens, and natural extracts can vary in composition. Conventional ingredients may offer excellent purity, consistency, and stability. The better ingredient is the one that satisfies the product's safety, performance, sourcing, retailer, environmental, sensory, and commercial requirements.
