Emulsions & Surfactants: How Clean Beauty is Rethinking Stability and Skin Compatibility
For years, clean beauty avoided emulsifiers and surfactants altogether—often out of fear, not science. But in 2025, brands are moving past the binary of “safe vs. synthetic” and into a more nuanced approach: selecting ingredients that are functional, gentle, and transparent about their source and purpose.
Today’s most innovative products aren’t oil-only or water-based—they’re microemulsions, gel creams, cleansing balms, and hybrid textures that rely on smart formulation and thoughtful ingredient pairing.
Emulsifiers That Respect the Skin Barrier
Modern clean formulations are shifting away from PEGs and harsh ethoxylated emulsifiers, focusing instead on skin-identical systems that offer stability without stripping or clogging.
What’s trending:
• Lecithin, polyglyceryl esters, and glyceryl stearate citrate
• Natural lamellar emulsifiers that mimic skin structure
• Sugar- and amino acid-derived systems that reduce TEWL and support microbiome health
• Self-emulsifying oils for water-activated formats
Why it matters: These systems create elegant, stable emulsions without the trade-offs of older systems—especially in creams, cleansing balms, and SPF products.
Raise the bar:
• Choose emulsifiers that support barrier repair, not just texture
• Communicate the function clearly on PDPs and marketing copy
• Match your emulsifier system to your brand’s sensorial identity
Mild, Biodegradable Surfactants for Modern Cleansers
The cleanser renaissance continues, and surfactants are finally getting the nuance they deserve. Today’s brands are prioritizing surfactants that cleanse effectively, preserve the skin barrier, and biodegrade quickly—without lingering impact on waterways or ecosystems.
What’s trending:
• Coconut- and sugar-derived surfactants like decyl glucoside, sodium cocoyl glutamate, and caprylyl/capryl glucoside
• Anhydrous cleansing sticks and balms with natural emulsifiers
• Biodegradable surfactant systems tested for aquatic safety and clean rinse-off
• Oil-to-milk cleansers with minimal foam and maximum compatibility
Why it matters: Consumers are becoming more ingredient-aware and environmentally conscious. Surfactants that are both gentle and readily biodegradable are now a core clean beauty expectation.
Get future-ready:
• Choose surfactant systems with published biodegradability and ecotoxicity data
• Educate on the benefits of non-foaming, non-stripping cleansers
• Highlight rinse-off performance and low environmental impact in your messaging
Emulsion Types That Enhance Performance and Play
Beyond ingredient safety, brands are now experimenting with emulsion types to elevate both performance and consumer experience. Form matters just as much as function.
What’s trending:
• Gel-to-cream and waterless emulsions for travel and sustainability
• Water-in-oil (W/O) emulsions for deeper occlusion and barrier protection
• Oil-in-water (O/W) systems for lighter, more hydrating delivery
• Novel hybrid textures like cream-to-serum and balm-to-milk
Why it matters: The emulsion structure impacts how actives are delivered, how long the formula stays stable, and how the user perceives quality.
Lead the shift:
• Choose your emulsion type based on both function and market positioning
• Consider stability in high heat, humidity, or transport conditions
• Use emulsion format as a storytelling tool—tie it back to brand identity and ritual
Transparency in Function and Source
As consumers become more sophisticated, they’re asking not just what an emulsifier or surfactant is, but where it comes from and what it’s doing in the formula.
What’s trending:
• Full INCI breakdowns with plain-language translations
• Ingredient glossaries with sourcing, role, and function per material
• Carbon-neutral or RSPO-certified surfactant sourcing
• Transparent documentation for greenwashing-prone categories like "coconut-derived" materials
Why it matters: Ingredient-savvy customers want proof of both efficacy and integrity. They’re no longer impressed by vague marketing claims.
Build with intention:
• Include ingredient origin and purpose in your PDPs and training materials
• Provide batch-level traceability and documentation when possible
• Let your formulator or chemist speak directly through your brand’s education
Final Thoughts: Formulation is the New Differentiator
In clean beauty, emulsifiers and surfactants were once a red flag. Today, they’re a strategic asset. The right system can elevate performance, protect the barrier, and deliver a luxurious experience—all while staying true to clean principles.
The most forward-thinking brands in 2025 are:
• Embracing barrier-friendly emulsifiers and next-gen surfactants
• Innovating with emulsion types and textures
• Prioritizing transparency over trendiness
• Building formulation stories that connect science to sensorial value
Because when a product works beautifully and tells the truth about how it’s made, consumers come back.
