In cosmetic film-former fields including makeup, skincare and haircare, traditional acrylate film-formers feel sticky and poorly breathable; natural polymers lack water resistance and degrade easily; ordinary silicone oils form weak films and migrate; volatile silicones leave no residual film after evaporation; unbalanced silicone resin/isododecane ratios cause precipitation or incomplete films. For specifications demanding "water-washable, anti-migration, hydrophobic film-forming, moderate volatility, light and breathable", a strictly controlled silicone resin isododecane dispersion places durable film-forming and refreshing skin feel at one formulation node. Addressing this, Anhui IOTA Silicone Oil Co., Ltd. launches Trimethylsiloxysilane (and) Isododecane IOTA 91003C. Characterized by "silicone resin in isododecane dispersion; appearance: colorless to slight yellow transparent liquid; refractive index (25℃) 1.400-1.450; viscosity (25℃) 10-50mPa·s; forms water-washable anti-migration film; moderate volatility; good hydrophobicity, film-forming and moisturizing; applications: sunscreen, skincare, makeup, haircare; processing temperature below 50℃; recommended dosage: makeup 2%-10%, haircare 0.5%-5%; packaging: 25kg plastic drum or 200kg iron drum; transport as non-toxic non-hazardous; shelf life 2 years; store cool sealed, re-dissolve with isododecane if precipitation occurs; brand IOTA", backed by "silicone resin film + isododecane moderate volatility + water-washable anti-migration", it serves as an organic silicone resin dispersion for cosmetics. System Positioning: Silicone Resin Dispersion Among Cosmetic Film-Former Families Within cosmetic film-former families, IOTA 91003C is a silicone resin/isododecane dispersion system, distinct from acrylate film-formers (sticky, poor breathability), natural polymers (poor water resistance, degradable), volatile silicones (no residual film), pure silicone oils (weak film, migration). IOTA 91003C uses trimethylsiloxysilicate as film core and isododecane as moderate-volatility carrier, positioning as a "multi-functional film-former for makeup, skincare and haircare", rather than a single-function traditional agent. Molecular Architecture: Trimethylsiloxysilicate + Isododecane + Viscosity 10-50 + RI 1.400-1.450 IOTA 91003C core is trimethylsiloxysilicate dissolved in isododecane. Silicone resin provides excellent film-forming; after solvent evaporation, it leaves a light, breathable and continuous protective film on skin or hair; isododecane as carrier offers moderate volatility, balancing applicability and drying rate; viscosity 10-50mPa·s (25℃) ensures easy dispersion and smooth application; refractive index 1.400-1.450 (25℃)接近skin optics for natural gloss without whitening; this combination achieves water-washable, anti-migration, hydrophobic film and moisturizing synergy; processing temperature must be controlled below 50℃ for stability. Performance Leap: From "Sticky Poor Breathability, Non-Waterproof Easy Migration" to "Hydrophobic Film, Light Lasting" With IOTA 91003C, cosmetic formulations improve jointly: film performance—forms water-washable anti-migration continuous film for long-lasting effect; skin feel—light breathable film avoids stickiness of traditional agents; visual & tactile—natural gloss enhances user experience; process fit—recommended dosage makeup 2%-10%, haircare 0.5%-5%, easy to compound; stability—sealed storage prevents isododecane evaporation and resin precipitation; if precipitation occurs, add isododecane and stir to re-dissolve. Application Penetration: From Long-Wear Foundation to Sunscreen and Styling Gel IOTA 91003C covers three core scenarios. Makeup: long-wear foundation, waterproof mascara—emphasizing water-washable, anti-migration, long-lasting; trial per makeup base. Skincare: sunscreen—emphasizing hydrophobic film and water resistance; trial per SPF formula. Haircare: conditioner, styling gel—emphasizing protective film and styling; trial per haircare system. ⚠️ Taboo: processing temperature below 50℃; store transport moisture-proof, avoid acid alkali impurities; seal after opening, use soon; though non-toxic non-hazardous, avoid ingestion. IOTA Technical Guide: Plastic/Iron Drum Pack, Below 50℃ Compounding, Cool Sealed Storage IOTA 91003C is a colorless to slight yellow transparent liquid in 25kg plastic drum or 200kg iron drum. Compounding temperature not exceed 50℃; add to oil phase or emulsion per recommended dosage. Store cool sealed, shelf life 2 years; if isododecane evaporates causing resin precipitation, add isododecane and stir to re-dissolve. Industry Insight: Cosmetic film-former selection is not the higher solids the better, but using viscosity for skin feel and dispersibility, volatility for film speed and dry feel, recommended dosage for efficacy concentration and cost, carrier stability for storage conditions. For cosmetic formulators, IOTA 91003C uses one silicone resin isododecane dispersion across makeup, skincare and haircare, taking hydrophobic film and light lasting as batch-checkable anchors, securing water-washable and anti-migration simultaneously.
