Global regulators are closing in on synthetic microplastics, leaving personal care formulators in a tough spot. Swapping out PMMA, Nylon-12, and silicone crosspolymers usually means sacrificing that velvety slip or soft-focus finish consumers expect. If you're formulating for the Indian market or exporting to the EU, you need a raw material that replaces microplastics without wrecking your product's sensory profile.
To solve this, Eastman launched Esmeri™ SK1N10, a readily biodegradable, non-nano cellulose ester micropowder. It operates as a high-performance functional filler that delivers instant soft-focus blurring, oil control, and active-compatible SPF boosting. For cosmetic chemists and contract manufacturing organizations (CDMOs), it offers a direct way to elevate formula aesthetics while staying ahead of tight regulatory deadlines.
Esmeri™ SK1N10 uses a dual-component structure listed under the INCI name *Cellulose Acetate Butyrate (and) Disodium Succinate*. Its engineered spherical particle shape directly improves how a formula feels and performs on skin:
Soft-Focus Photometrics: The spherical particles scatter incident light evenly, instantly softening fine lines and delivering a matte, blurred finish.
Selective Sebum Control: It absorbs excess surface oil without stripping natural epidermal moisture, keeping skin balanced rather than dry or chalky.
Active Protection: The chemically inert cellulose ester matrix shields delicate actives like retinoids and L-ascorbic acid from oxidation, preserving active potency throughout shelf life.
Easy Dispersibility: Disodium succinate surface treatment keeps particles well-dispersed in O/W and water-heavy systems, preventing clumping even under high-shear batch processing.
In sun care formulations, Esmeri™ SK1N10 does more than adjust sensory feel—it alters how light interacts with physical and chemical UV filters:
Prevents UV Filter Aggregation: It stops organic and inorganic filters from clumping, ensuring a smooth, uniform film across the stratum corneum.
Extends Optical Light Paths: By inducing multi-directional light scattering within the applied film, the micropowder lengthens the travel path of UV radiation, directly driving up measured SPF values.
Lowers BOM Costs: Formulators can hit target SPF ratings with lower concentrations of expensive organic UV filters. Reducing filter loads slashes your Bill of Materials (BOM) costs while creating a light, dry-touch feel that excels in humid climates.
Meeting regulatory standards in India demands clear compliance strategies. Esmeri™ SK1N10 offers direct regulatory advantages for domestic brands and exporters alike:
Non-Nano Clearance: As a verified non-nano material, Esmeri™ SK1N10 skips the complex safety dossiers and toxicological testing mandates required for nanomaterials under CDSCO and the *Drugs and Cosmetics Rules, 2020*.
Microplastic Ban Compliance: The ingredient aligns with Bureau of Indian Standards (BIS) rules and international bans on microplastics in leave-on and rinse-off products.
Export-Ready Profile: Swapping synthetic polymers for bio-based cellulose esters gives Indian OEMs and ODMs a smooth regulatory pass across the EU, US, and ASEAN markets.
Eastman Esmeri™ SK1N10 works as a simple drop-in replacement across active serums, blurring primers, and hybrid sunscreens. By combining optical blurring, active stabilization, and SPF boosting, it gives cosmetic chemists a reliable tool to trim formulation costs, meet microplastic phase-out deadlines, and get new products onto shelves faster.
