Tert-Butyl Acrylate Copolymer, Cosmetic Film Former
Tert-Butyl Acrylate Copolymer is a new generation of flexible high-adhesion cosmetic film-forming polymer optimized for all-weather long-wearing makeup. Different from traditional ordinary acrylate polymers with single rigid film formation and poor environmental adaptability, this product introduces steric hindrance tert-butyl structure to optimize the molecular chain flexibility and intermolecular adhesion.
It achieves a perfect balance of water resistance, flexibility, adhesion and low-temperature resistance. The formed film is dense and tough, not easy to crack at low temperature, not easy to peel off when encountering water and sweat, and fits closely with skin and pigment particles.
It can significantly improve the wear resistance and weather resistance of makeup, avoid makeup fading, warping and peeling caused by temperature and humidity changes, and maintain a complete and delicate makeup state for a long time. It is an upgraded core raw material for high-end durable color makeup, solving the durability and adaptability bottlenecks of traditional film-forming agents.
Key Benefits
• Ultra-High Adhesion, Firm Long-Lasting Makeup: Unique tert-butyl steric hindrance structure enhances intermolecular binding force, greatly improves the adhesion between film layer, skin and pigment powder. It firmly locks makeup texture, effectively resists daily friction and scratch, and solves common problems such as makeup floating, peeling and fading, achieving 8–12 hours stable long-lasting makeup.
• Flexible & Tough Film, No Low-Temperature Cracking: Different from the hard and brittle film of traditional acrylate resins, the optimized flexible molecular chain endows the film with excellent ductility and toughness. It adapts to low-temperature and dry environments without cracking or peeling, solves the winter makeup cracking pain point, and greatly improves all-weather makeup stability.
• Excellent Water & Sweat Resistance, Anti-Fading: The dense hydrophobic film structure can effectively isolate sweat, water vapor and environmental moisture erosion, prevent makeup water blushing, color bleeding and fading. It maintains clear and uniform makeup color in sweating and humid environments, with outstanding waterproof and moisturizing barrier performance.
• Soft & Skin-Friendly Film, No Stiff Feeling: The film layer is soft and breathable with moderate hardness, no tightness or stiff mask feeling after molding. It fits the skin’s natural stretching movement, does not crack when smiling and moving, and retains natural skin texture while ensuring makeup durability, with superior wearing comfort.
• Strong Environmental Adaptability, Stable in Cold & Heat: It has excellent temperature resistance, stable film performance in both high-temperature humid and low-temperature dry environments, no viscosity change, no film aging or failure. It perfectly adapts to complex seasonal and regional climate changes, suitable for all-weather long-wearing cosmetic formulas.
• Safe & Compatible, Wide Application Range: Adopts environmentally friendly polymerization process, no harmful residues, low irritation and high safety. Compatible with various water-based cosmetic systems and various pigments, wax emulsions and active ingredients, stable compounding without system abnormality, suitable for high-end clean beauty and sensitive skin makeup.
Applications
• Eye Makeup Series: Core film-forming and adhesive raw materials for waterproof mascara, long-lasting liquid eyeliner, eye shadow primer and eye makeup setting gel. It enhances eye makeup water resistance and friction resistance, prevents eyeliner smudging and mascara flaking, and maintains sharp and delicate eye makeup all day.
• Long-Lasting Lip Makeup: Special flexible film former for matte lip glaze, tinted lip tint, waterproof lipstick and long-wearing lip primer. It locks lip color firmly, resists drinking water and eating rubbing, avoids lip color fading and blooming, and keeps lip makeup full and uniform for a long time.
• Durable Base Makeup: Applied in long-lasting matte foundation, waterproof concealer, oil-control base primer and setting emulsion. It improves the adhesion and durability of base makeup, prevents floating powder and makeup removal caused by sweat and friction, and creates long-lasting clean base makeup.
• All-Weather Outdoor Cosmetics: Preferred polymer for outdoor sun-proof makeup, sports long-wearing cosmetics, travel portable makeup and seasonal adaptive beauty products. It adapts to high temperature, humidity, low temperature and dry complex environments, with outstanding weather resistance.
• Water-Based Long-Lasting Color Makeup: Suitable for various water-based durable color makeup, waterproof tinted cream and makeup fixing products. It stabilizes color system, enhances film flexibility, and solves the problems of hard film, easy cracking and poor durability of traditional film-forming agents.
• Sensitive Skin Mild Makeup: Low-irritation safe film-forming raw material for mild long-wearing cosmetics and clean beauty products. It does not contain irritating ingredients, balances durability and skin friendliness, and meets the formula requirements of high-end mild makeup.
