Aminomethyl Propanol Acrylate Copolymer-CAS 24938-16-7
Aminomethyl Propanol Acrylate Copolymer is a high-performance cationic modified acrylic polymer exclusive for long-lasting cosmetics and professional hair styling.
Different from traditional anionic acrylate film formers with passive film-forming, it adopts active cationic adsorption technology, which can firmly combine with negatively charged skin, hair and powder particles, achieving ultra-high adhesion and long-lasting shaping effect.
The formed polymer film is flexible, breathable, sweat-resistant and non-stiff, avoiding the dry and tight feeling of traditional styling polymers. It not only has excellent fixing and anti-fading performance, but also provides mild conditioning effect, effectively improving dry and frizzy hair and rough skin texture.
Meanwhile, it can adjust formula viscosity and rheological stability, optimize product texture and storage stability. With the dual advantages of cosmetic shaping and mild conditioning, it has become a mainstream core raw material in long-wearing makeup and professional hair care and styling fields.
Key Benefits
• Active Cationic Adsorption, Super Long-Lasting Adhesion: Unique amino cationic structure realizes active bonding with skin, hair and powder, far exceeding the passive adhesion of ordinary acrylate polymers. It firmly locks makeup and hairstyle, effectively resists daily friction and facial movement, and solves the problems of makeup fading and hairstyle collapse.
• Excellent Sweat & Water Resistance, Anti-Melting & Anti-Fading: The flexible and dense film layer has outstanding sweat resistance and water resistance, which can isolate sweat and water erosion. It maintains stable makeup and hairstyle in sweating and humid environments, achieving all-day long-lasting effect without mottling or loosening.
• Non-Stiff & Breathable Film, Natural Comfortable Feeling: Different from hard and stiff film of traditional styling polymers, the film is soft, light and breathable after molding, no tightness, no whitening, no heavy residue. It retains natural skin and hair activity while shaping, with zero burden.
• Dual Skin & Hair Conditioning Effect: Amino functional groups bring mild moisturizing and conditioning performance, which can smooth rough hair scales, improve dry and frizzy hair, and relieve skin dryness. It integrates shaping and nourishing, realizing functional upgrading of cosmetics.
• Rheology Modification & System Stabilization: It has moderate and stable thickening performance, which can finely adjust the viscosity and fluidity of water-based formulas, improve product ductility and touch, effectively prevent pigment and active particle settlement, and extend product shelf stability.
• Ultra-Mild & Wide Compatibility: Low-sensitization and non-irritating formula, no formaldehyde and harmful volatile substances. Compatible with most water-based cosmetic systems, stable compounding with various surfactants and active ingredients, suitable for sensitive skin and mild clean beauty formulas.
Applications
• Long-Lasting Makeup Setting Series: Core functional raw material for setting spray, setting lotion and long-lasting makeup base. It improves makeup adhesion, resists sweat and oil erosion, prevents floating powder and fading, and maintains all-day clean and delicate base makeup.
• Base Makeup Products: Widely used in matte long-lasting liquid foundation, BB cream, CC cream and concealer. It optimizes base makeup ductility, enhances powder fitting degree, stabilizes emulsion system, and solves the problem of makeup mottling and fading.
• Professional Hair Styling Products: Suitable for hair styling gel, hair mousse, hair setting spray and fluffy styling cream. It provides natural and long-lasting shaping, prevents hair collapse and frizz, and keeps hair fluffy and stereotyped all day without stiffness.
• Moisturizing Skincare Products: Applied in moisturizing toner, soothing lotion and hydrating gel. It acts as thickening and stabilizing agent to optimize product texture, lock skin moisture, and improve skin smoothness and delicacy.
• Mild Clean Beauty Cosmetics: Added in sensitive skin mild makeup and zero-addition clean beauty products. Ultra-mild and low-sensitization, it stabilizes the formula without irritation, meeting the demand of high-end mild cosmetics.
• Functional Water-Based Cosmetics: Perfectly adapted to various transparent water-based and gel cosmetic formulas, improving product stability, touch and long-lasting performance without affecting product transparency.
