Cosmetic Grade Acrylates/Octylacrylamide Copolymer
Cosmetic Grade Acrylates/Octylacrylamide Copolymer is a high-performance oil-soluble film-forming resin specially developed for long-lasting waterproof color cosmetics. Introduced with unique octylacrylamide hydrophobic groups in the molecular chain, it endows the film layer with excellent waterproof, sweat-proof and anti-smudge properties, making up for the defect of poor water resistance of traditional water-based acrylic film formers.
The formed polymer film is dense, tough and moderately flexible, with super high adhesion to skin and cosmetic pigments. It can firmly lock the pigment formula, prevent color bleeding, fading and rubbing off, and maintain the integrity and clarity of eye makeup and lip makeup for a long time.
With safe and mild properties, no irritation to sensitive eye skin, stable formula compatibility and excellent weather resistance, it is the core preferred functional raw material for high-end waterproof and long-wear color cosmetics.
Key Benefits
• Superior Waterproof & Sweat-Proof Performance: Unique hydrophobic molecular structure forms dense water-repellent film, effectively resisting the erosion of sweat, tears and rainwater, completely solving eye makeup smudging and blooming problems.
• Powerful Anti-Transfer & Anti-Smudge: High film compactness locks pigment tightly, prevents makeup from rubbing off on masks, clothes and skin, maintains clean makeup all day, suitable for high-precision long-wear makeup.
• Tough Film & No Brittle Cracking: Moderate film hardness and excellent flexibility, fits skin stretching and movement, no dry cracking, peeling or flaking, natural and comfortable makeup feeling.
• High Adhesion & Long-Lasting Color Locking: Super adhesion to skin and pigments, stable color development without fading or mottling, greatly extends makeup wear time and improves cosmetic durability.
• Mild & Eye-Safe Formula: Cosmetic-grade deep purification, ultra-low residual monomers, non-irritating and non-sensitizing, specially adapted for sensitive eye area makeup products.
• Excellent Oil-System Compatibility: Perfectly compatible with oil-phase and solvent-based cosmetic formulas, stable batch performance, no delamination or deterioration, friendly for standardized mass production of high-end cosmetics.
Applications
• Waterproof Eye Makeup Series: Core film-forming and fixing raw material for waterproof mascara, long-lasting eyeliner liquid, smudge-proof eyeliner paste and anti-fading eye shadow, realizing zero-smudge long-wear eye makeup effect.
• Long-Lasting Lip Makeup Products: Used in transfer-resistant lipstick, waterproof lip gloss and matte long-wear lip tint, lock lip color firmly, prevent lip makeup fading and tooth staining, improve lip makeup durability.
• High Weather-Resistance Color Cosmetics: Suitable for sweat-proof and waterproof face makeup, contour color paste and long-wear blush, enhance makeup resistance to external moisture and friction.
• Anhydrous Makeup Formulas: Perfectly adapted to anhydrous powder-oil composite systems, oil-based tinting pastes and high-concentration color cosmetic formulas, stabilize pigment dispersion and improve formula uniformity.
• Professional Body Makeup: Applied in body paint and temporary tattoo makeup, form stable waterproof film, prevent color fading and transfer, maintain long-term complete coloring effect.
• High-End Custom Long-Wear Makeup: Used in all kinds of customized long-lasting, waterproof and anti-transfer high-grade cosmetics, greatly improve product core competitiveness.

Frequently Asked Questions (FAQ)
• Q1: What is the MOQ of Cosmetic Grade Acrylates/Octylacrylamide Copolymer?
A1: The standard MOQ is 25KG, and sample orders are supported for formula testing and trial production.
• Q2: Is this copolymer safe for eye makeup products?
A2: Yes. The product adopts high-standard cosmetic purification process with ultra-low residual monomers and heavy metals. It is non-toxic, non-irritating and non-sensitizing, fully compliant with international eye-contact cosmetic safety standards, safe for long-term use on sensitive eye skin.
• Q3: What is the recommended dosage in cosmetic formulas?
A3: Waterproof mascara & eyeliner: 3.0%–8.0%; Long-lasting lip makeup: 2.0%–6.0%; Anti-transfer face makeup: 1.5%–5.0%; Anhydrous color cosmetics: 1.0%–4.0%; Body painting makeup: 2.5%–7.0%, adjustable according to target waterproof and anti-smudge effect.
• Q4: What is the difference from ordinary acrylates copolymer?
A4: Ordinary acrylates copolymer is water-based with poor water resistance, easy to smudge and transfer. Acrylates/Octylacrylamide Copolymer is oil-soluble with strong hydrophobicity, featuring professional waterproof, sweat-proof and anti-transfer performance, tough film and no brittle cracking, specially developed for high-resistance long-lasting eye and lip makeup.
• Q5: What formula systems is it compatible with?
A5: Mainly suitable for oil-phase, solvent-based and anhydrous composite systems, perfectly compatible with ester solvents, ethanol, cosmetic greases and color pigments. Stable compounding performance without flocculation or delamination.
• Q6: What are the formula matching notes?
A6: Dissolve and disperse in oil phase or ethanol solvent first to ensure uniform system; avoid excessive high dosage to prevent film stiffness; match with softening grease to optimize makeup comfort; store finished products in sealed and dry environment to maintain stable waterproof performance.
• Q7: Do you support stable mass supply and customized processing?
A7: Strict batch solid content, viscosity and monomer residue control ensure stable film-forming and waterproof performance. Support customized solid content and viscosity grades. Sufficient inventory all year round supports long-term bulk orders and professional formula technical guidance.
