Styrene/Acrylates Copolymer-CAS 25034-86-8
Styrene/Acrylates Copolymer is a high-rigidity water-based composite polymer tailored for high-color-fastness long-lasting cosmetics. Traditional single acrylate polymers have soft film texture, poor wear resistance and obvious pigment migration, which cannot meet the high durability requirements of color makeup and nail products.
This product adopts styrene rigid segment modification technology, which greatly improves the hardness, scratch resistance and water resistance of the film layer on the premise of retaining the excellent film-forming ductility of acrylate. It forms a dense, hard and tough transparent protective film on the skin and coating surface, which can firmly lock pigment particles, effectively resist daily friction, water washing and sweat erosion, and completely solve the problems of makeup blooming, color fading and surface scratching.
With unique rigid-tough balanced performance and excellent anti-migration and waterproof advantages, it has become the core designated raw material for high-end waterproof and long-lasting color cosmetics and water-based nail art products.
Key Benefits
• Rigid Modified High-Hardness Film, Super Scratch Resistance: Unique styrene rigid structure significantly improves film hardness, far exceeding ordinary acrylate polymers. The film surface is smooth and wear-resistant, not easy to be scratched or worn off, effectively improving the durability and surface texture of color makeup and nail products.
• Powerful Pigment Anti-Migration, No Blooming & Fading: It can uniformly and tightly wrap pigment and color powder particles, inhibit the diffusion and migration of color molecules, thoroughly solve the problems of eyeliner smudging, eyeshadow blooming and lip gloss color bleeding, and maintain clear and three-dimensional makeup boundaries.
• Excellent Waterproof & Sweat Resistance, Long-Lasting Stability: The dense cross-linked film layer has outstanding water and sweat isolation ability, resists washing and sweat erosion, does not melt or fade in humid and sweating environments, and realizes all-day long-lasting color locking and makeup fixing.
• Rigidity-Toughness Balance, No Cracking & Peeling: Complementary advantages of styrene rigidity and acrylate toughness, the film layer is hard but not brittle, with good bending and impact resistance. It avoids the defects of hard film brittleness, cracking and peeling of single rigid polymer, and has more stable application performance.
• Stable Formula System, Wide Compatibility: Excellent water-based dispersion stability, no agglomeration or flocculation during compounding. Compatible with various water-based color makeup, nail polish and emulsion formulas, it can optimize product fluidity and storage stability without affecting product color and transparency.
• Safe & Mild, Compliance Grade: Adopts environmentally friendly water-phase polymerization process, no harmful residual monomers, no formaldehyde, low irritation and high safety. Fully compliant with global cosmetic regulations, suitable for high-end clean beauty and mild cosmetic formula development.
Applications
• Water-Based Nail Cosmetics: Core film-forming and fixing raw material for water-based nail polish, nail color sealant and nail base coat. It forms a high-hardness wear-resistant coating, improves nail surface gloss and durability, resists daily scratching and water washing, and prolongs nail color retention time.
• Waterproof Eye Makeup Series: Widely used in waterproof eyeliner, long-lasting eyebrow cream, anti-blooming eyeshadow primer and pressed eyeshadow. It inhibits color migration and blooming, keeps eye makeup clear and sharp for a long time, and solves the problem of eye makeup smudging and fading.
• Long-Lasting Lip Makeup Products: Suitable for tinted lip gloss, matte lip glaze and long-lasting lip tint. It locks lip color firmly, prevents color bleeding and fading, improves lip makeup adhesion and comfort, and achieves long-lasting non-fading lip makeup effect.
• High Color Fastness Color Makeup: Applied in long-lasting blush, contour powder, tinted moisturizer and color correcting cream. It stabilizes pigment dispersion, prevents color precipitation and migration, ensures uniform and long-lasting makeup color, and improves product grade.
• Waterproof Styling Products: Added in water-based hair styling gel and colored hair styling products. It enhances the waterproof and wear resistance of styling films, fixes hair shape stably, and avoids styling collapse and color fading.
• Functional Water-Based Emulsions: Perfectly adapted to various water-based cosmetic emulsion systems, improve formula rheological stability and color uniformity, and extend product shelf life.
