Acrylates/Dimethicone Copolymer(CAS 143151-63-9)
KP-545 Acrylates/Dimethicone Copolymer is a high-performance silicone-acrylic composite film-forming agent exclusive for cosmetics. It breaks through the single performance limitation of traditional acrylic film formers and silicone additives, organically combining the flexible film-forming property of acrylate and the smooth waterproof advantage of dimethicone.
The formed film is transparent, tough, breathable and non-tight, with excellent water resistance and rubbing resistance. It can significantly improve the adhesion and uniformity of cosmetic products on the skin, effectively resist the erosion of sweat, sebum and external friction, and achieve long-lasting makeup holding effect.Meanwhile, it can optimize skin surface texture, reduce dry lines and rough feeling, endow skin and makeup with delicate silky matte texture, and greatly improve the grade and durability of cosmetic finished products. With mild safety and excellent comprehensive performance, it is the mainstream core film-forming raw material for high-end waterproof and long-wearing cosmetics in the market.
Key Benefits
• Silicone-Acrylic Composite, Balanced Performance: Integrates the high toughness of acrylate film and the smooth waterproof property of silicone, avoiding the defects of brittle film of single acrylic agent and insufficient film-forming strength of single silicone agent, achieving perfect balance of flexibility, waterproofness and air permeability.
• Ultra-Transparent Film Formation, No Fake White Mask Feeling: The film layer is crystal clear with no haze or whitening after molding. It does not affect the original color and gloss of makeup, maintains natural and transparent skin texture, and solves the problem of dull and whitened makeup caused by ordinary film formers.
• Excellent Waterproof & Sweatproof, Long Lasting Makeup: Dense hydrophobic protective film can effectively isolate sweat and sebum, resist daily friction and wiping, prevent floating powder, cracking and fading, and greatly extend the makeup holding time of foundation, lipstick and sunscreen.
• Smooth Texture Modification, Delicate Skin Feeling: It can fill fine dry lines and smooth rough skin texture, endow cosmetics with excellent spreadability and ductility, bring silky matte non-greasy skin feeling, and improve the delicate grade of finished products.
• Flexible & Breathable Film, Zero Skin Burden: The film layer has good tensile flexibility, no tight or heavy feeling after application, with excellent air permeability, effectively avoiding stuffy skin and makeup peeling caused by rigid film layer, suitable for daily long-term makeup.
• Wide Formula Compatibility & High Stability: Stable compatibility with oil-based, emulsion-based and various cosmetic solvent systems, no demulsification, delamination or precipitation. It has good compatibility with pigments, powders and functional active ingredients, stable batch performance for industrial mass production.
Applications
• Long-Lasting Foundation & Concealer: Core film-forming and fixing raw material for matte long-wearing foundation and waterproof concealer, effectively improving makeup adhesion, preventing floating powder and cracking, and realizing all-day stable makeup.
• Waterproof Lip Makeup Series: Applied in matte lipstick, velvet lip glaze and tinted lip balm, enhance the water resistance and color fastness of lip makeup, solve the problem of fading and staining cups, and maintain long-lasting full color.
• Waterproof & Sweatproof Sunscreen: Used in outdoor high-power sunscreen lotion and cream, form a dense protective film to resist water and sweat erosion, prevent sunscreen failure caused by sweating and water contact, and improve outdoor protection durability.
• Makeup Setting & Primer Products: Suitable for setting spray, oil-control isolation primer and skin smoothing base cream, optimize base skin texture, improve makeup fitting degree, and lay a stable foundation for subsequent makeup.
• Matte Delicate Skin Care Products: Added in silky smoothing essence and oil-control skin care lotion, modify skin rough texture, form breathable protective film, balance skin oil and moisture, and bring long-lasting matte fresh skin feeling.
• Waterproof Color Cosmetics: Widely used in eyeliner, mascara, eyebrow powder and other waterproof color cosmetics, enhance product water and rub resistance, and avoid makeup smudging and blooming.
