Polyurethane-40, Cosmetic Hard Film-forming Polyurethane
Polyurethane-40 is a high-performance high-hardness cosmetic polyurethane polymer developed for high-gloss, wear-resistant and ultra-long-lasting cosmetic formulas. Different from soft-series Polyurethane-2 and flexible-tough Polyurethane-34, this product adopts optimized high-rigidity cross-linked molecular structure, featuring high film hardness, excellent light transmittance and superior gloss enhancement performance.
It can form a highly transparent, smooth and dense protective film on skin and hair surface, with outstanding waterproof, anti-sebum, scratch-resistant and wear-resistant properties. It has ultra-strong pigment locking and anti-migration capabilities, which can firmly bind color pigments and cosmetic powders, effectively solving makeup fading, transferring, rubbing and abrasion problems.
In hair styling applications, it provides stable high-strength holding power, realizing long-lasting stereotyped shaping without easy collapse. The film layer is high-gloss and translucent, which can significantly improve the glossiness of cosmetics and hair. With stable chemical properties, wide pH adaptability, excellent formula compatibility and mild non-irritating characteristics, it is the core high-performance functional raw material for high-gloss color cosmetics, waterproof long-wear makeup and strong-hold hair styling products.
Key Benefits
• High-hardness Dense Film, Super Wear Resistance: Unique rigid cross-linked structure forms high-density tough film layer, effectively resisting external friction and scratching, solving the easy-wear defect of soft polyurethane film layers.
• High-transparency High-gloss Enhancement: Excellent light transmittance and gloss modification performance, endowing cosmetics and hair with natural bright glossy texture, avoiding dull and flat makeup effect.
• Ultra-strong Color Locking & Anti-transfer: Super pigment binding and anchoring capacity, firmly locks color molecules, effectively preventing lipstick and foundation from transferring, fading and bleeding, realizing zero-transfer long-lasting makeup.
• High-strength Stereotyped Hair Styling: Provides durable high-hardness holding power for hair, tames messy frizz, maintains long-term neat hairstyle, wind-resistant and pressure-resistant, no easy collapse or deformation.
• Excellent Waterproof & Anti-sebum Stability: Dense film structure effectively isolates sweat and sebum erosion, greatly improves the water and oil resistance of formulas, and extends the lasting time of makeup and styling.
• Mild Safe & Wide Compatibility: High-purity cosmetic grade polymer, no harmful residues, low irritation, stable in full pH range, compatible with various oils, waxes and powders, compliant with global cosmetic safety standards.
Applications
• High-gloss Lip Color Cosmetics: Waterproof non-transfer lipstick, high-gloss lip gloss, long-lasting tinted lip balm, anti-bleeding lip makeup formulas.
• Ultra-long-wear Base Makeup Products: Wear-resistant long-lasting foundation, high-stability oil-control cushion, anti-friction makeup primer, zero-transfer BB/CC cream.
• High-strength Hair Styling Series: Strong-hold setting spray, stereotyped styling mousse, long-lasting anti-frizz hair cream, salon-grade shaping products.
• Waterproof Functional Sunscreen: High wear-resistant waterproof sunscreen, outdoor long-acting sun protection formula, sweat-resistant and anti-fading sunscreen products.
• High-stability Finishing Products: Wear-resistant setting powder/pressed powder, long-lasting makeup fixative, high-gloss cosmetic finishing raw materials.

Frequently Asked Questions (FAQ)
• Q1: What are the differences between Polyurethane-40, PU-2 and PU-34?
A1: PU-2 is ultra-light and transparent for nude makeup and soft styling; PU-34 is flexible and tough for matte anti-cracking long-wear makeup; PU-40 is high-hardness, high-gloss and super wear-resistant, focusing on anti-transfer lip makeup, scratch-resistant long-wear base makeup and high-strength hair styling, filling the performance gap of high-hardness glossy polyurethane in cosmetic formulas.
• Q2: What is the recommended formula addition ratio?
A2: 3%-8% for high-gloss lip cosmetics, 2%-6% for wear-resistant long-wear foundation, 3%-7% for waterproof sunscreen, 4%-9% for strong-hold hair styling products, adjustable according to formula gloss, wear resistance and shaping strength requirements.
• Q3: Can Polyurethane-40 effectively solve lipstick transfer problems?
A3: Yes. The high-density rigid film layer has excellent anti-migration and anti-friction properties, which can tightly lock lip color pigments, resist daily friction and contact, significantly reducing lipstick smudging, transferring and fading, achieving long-lasting non-stick cup effect.
• Q4: Will high-hardness film cause tight skin or stiff hair?
A4: No. Although it has high film hardness and wear resistance, the molecular structure contains moderate flexible segments, which avoids excessive brittleness. It fits skin and hair naturally without obvious tightness, and realizes strong shaping without stiff and rigid hair texture.
• Q5: What formula systems is it suitable for?
A5: Suitable for water phase, oil phase and emulsion composite systems, perfectly compatible with various polyurethane resins, acrylic resins, silicone oils, esters and cosmetic powders, effectively improving formula gloss and comprehensive durability.
• Q6: Does it support stable bulk supply and technical services?
A6: Standardized high-end cosmetic grade production with stable batch hardness, gloss and film-forming performance, sufficient inventory, supports long-term bulk supply and global export, and provides professional formula debugging, high-gloss effect and wear-resistant system optimization technical support.
