Acrylates/Trimethylsiloxymethacrylate Copolymer
Cosmetic Grade Acrylates/Trimethylsiloxymethacrylate Copolymer is a high-end silicone-modified acrylic composite functional resin exclusive for long-wear cosmetics. Different from single acrylic film formers with stiff film and poor skin feel and single silicone film formers with weak color-locking adhesion, this product adopts complementary copolymerization technology.
It introduces trimethylsiloxane hydrophobic and smooth functional groups into the acrylic molecular chain, realizing perfect balance of high adhesion color fixation, super waterproof anti-smudge and silky skin feel.
The formed nano-level dense breathable film is tightly attached to the skin, with excellent ductility and fit, no tightness or whitening. It can effectively lock cosmetic pigments, resist external water and friction damage, maintain long-term makeup integrity, and is the core upgraded raw material for high-quality waterproof and long-lasting color cosmetics.
Key Benefits
• Silicone-Acrylic Dual Performance Upgrade: Combine the strong color-locking adhesion of acrylic resin and the waterproof, smooth and breathable advantages of silicone resin, solving the performance defects of single film-forming agent.
• Professional Waterproof & Anti-Smudge: Unique siloxane hydrophobic structure builds dense water-repellent film, effectively resisting sweat and tear erosion, completely improving eye makeup smudging and lip makeup fading problems.
• Super Anti-Transfer & Long-Lasting: High compact film structure firmly locks pigments, prevents makeup from rubbing off on masks and clothes, maintains all-day clean makeup, and greatly improves cosmetic durability.
• Silky Non-Greasy Skin Feel: The silicone group optimizes product texture, eliminates greasy and sticky residue, endows makeup with smooth matte delicate finish, and improves application experience.
• Tough Film & No Dry Cracking: Moderate film hardness and excellent flexibility, fit skin stretching movement, no peeling or flaking, natural and comfortable long-term makeup effect.
• High Safety & Wide Compatibility: Cosmetic-grade deep purification, low irritation and low sensitization, suitable for sensitive skin and eye makeup; compatible with oil-phase and emulsion systems, stable batch quality for mass production.
Applications
• Waterproof Eye Makeup Series: Core film-forming fixing material for waterproof mascara, long-lasting eyeliner liquid/paste and anti-smudge eye shadow, effectively solving eye makeup blooming and fading to achieve zero-smudge long-wear effect.
• Long-Lasting Lip Makeup Products: Applied in anti-transfer lipstick, waterproof lip gloss and matte long-wear lip mud, lock lip color firmly, prevent cup staining and fading, and improve lip makeup staying power.
• High-Durability Base Makeup: Suitable for long-wear foundation, concealer and tinted primer, optimize foundation ductility and fitting degree, prevent floating powder and makeup removal, and stabilize base makeup effect.
• High Weather-Resistance Color Cosmetics: Used in sweat-proof and waterproof outdoor makeup, contour paste and long-lasting blush, enhance makeup resistance to moisture and friction, adapt to complex environmental scenes.
• Emulsion Type Long-Lasting Formulas: Compatible with partial water-oil emulsion systems, used in fixed makeup lotion and long-wear isolation cream, balance film-forming performance and skin feel, and improve formula stability.
• High-End Custom Makeup: Preferred upgrading raw material for all kinds of high-grade waterproof, anti-transfer and silky matte long-wear cosmetics, improving product core competitiveness.

Frequently Asked Questions (FAQ)
• Q1: What is the MOQ of this silicone-modified copolymer?
A1: The standard MOQ is 25KG, and sample orders are supported for formula testing and trial production.
• Q2: What are the advantages compared with ordinary acrylic copolymer?
A2: Ordinary acrylic copolymer has stiff film, poor skin feel and obvious tightness; this silicone-modified copolymer integrates silicone smoothness and water resistance, with silky non-greasy skin feel, stronger waterproof and anti-transfer performance, flexible film without cracking, and more suitable for high-end long-wear makeup.
• Q3: What is the recommended dosage in cosmetic formulas?
A3: Waterproof eye makeup: 2.5%–7.0%; Long-lasting lip makeup: 2.0%–5.5%; Long-wear base makeup: 1.0%–4.0%; Emulsion makeup products: 0.8%–3.0%, adjustable according to target waterproof and skin feel requirements.
• Q4: Is the product safe for eye and sensitive skin?
A4: Yes. Adopts cosmetic-grade deep purification process with ultra-low residual monomers and heavy metals, non-toxic, non-irritating and non-sensitizing. It meets international eye-contact cosmetic safety standards and can be safely used in sensitive skin and eye makeup products.
• Q5: What formula systems is it compatible with?
A5: Mainly compatible with oil-phase, solvent-based and oil-in-water emulsion systems, perfectly matched with ester solvents, ethanol, cosmetic greases and color pigments, with stable compounding performance without delamination or flocculation.
• Q6: What are the formula usage notes?
A6: Preferentially dissolve and disperse in oil phase or ethanol to ensure uniform system; control reasonable dosage to avoid excessive film thickness leading to slight stiffness; cooperate with soft grease to optimize silky skin feel; seal and store finished products to maintain stable waterproof performance.
• Q7: Do you support customized processing and stable bulk supply?
A7: Strictly control batch solid content, viscosity and residual monomers to ensure stable film-forming and waterproof performance. Support customized viscosity and solid content grades. Sufficient inventory all year round provides long-term stable bulk supply and professional formula technical guidance.
