Polyurethane-2, Cosmetic Polyurethane Polymer
Polyurethane-2 is a high-performance water-based flexible polyurethane polymer specially customized for mild and light cosmetic formulas. Adopting optimized low-tack elastic molecular structure, it abandons the hardness and brittleness of traditional acrylic resins and the heavy viscosity of ordinary polyurethane film-forming agents.
The product features ultra-light film-forming property, high air permeability and excellent ductility, which can form a transparent, thin and uniform protective film on the surface of skin and hair without tightness, accumulation or sticky residue.
It has moderate powder binding and color fixing capabilities, which can effectively improve makeup adhesion and prevent light floating powder and fading, maintaining natural and transparent makeup texture.
In hair styling formulas, it provides soft and lasting shaping force, effectively tames frizzy hair and flying hair without stiff crusting or hair collapse. With excellent water solubility and formula compatibility, stable performance in wide pH range, mild and non-irritating, no peculiar smell, it is a core lightweight functional raw material for modern natural skin care, light makeup and flexible hair styling products.
Key Benefits
• Ultra-light Transparent Film-forming, No Tightness: Unique low-tack elastic molecular chain forms thin and breathable transparent film, no hard texture or skin tightness, maintaining the original natural skin texture.
• Mild Fixed-color & Natural Makeup Retention: Moderate powder binding force avoids heavy makeup feeling, effectively resists slight sweat and oil erosion, prevents faint floating powder and fading, and creates long-lasting light makeup effect.
• Soft Flexible Styling, No Stiff Crust: Provides gentle and lasting shaping power for hair, tames frizz and flying hair, realizes natural fluffy styling without hard crusting, stickiness or hair collapse.
• Super Water Solubility & Easy Formula Operation: Excellent water-soluble performance, no high-temperature stirring required, easy to disperse evenly in water phase system, simplifying production process.
• Wide pH Adaptability & Stable System: Stable in acidic, neutral and weak alkaline cosmetic systems, compatible with various surfactants, oils and powder raw materials, no delamination or precipitation.
• High Safety & Mild Skin-friendliness: High-purity cosmetic grade polymer, no harmful residues, ultra-low irritation, compliant with global cosmetic safety standards, suitable for sensitive skin and daily mild makeup formulas.
Applications
• Light & Transparent Base Makeup: Lightweight nude foundation, transparent makeup primer, natural moisturizing BB cream, non-makeup feeling long-wear base makeup products.
• Mild Skin Care Products: Moisturizing protective lotion, breathable skin care essence, mild finishing skin care formula, sensitive skin daily maintenance products.

Frequently Asked Questions (FAQ)
• Q1: What is the difference between Polyurethane-2 and Polyurethane-34?
A1: Polyurethane-34 focuses on high toughness, strong adhesion and matte long-wear effect; Polyurethane-2 features ultra-light, low-tack and high-transparency, focusing on natural nude makeup and soft hair styling. It has no heavy film feeling and stiff shaping, which is more suitable for light and mild cosmetic formulas.
• Q2: What is the recommended formula addition ratio?
A2: 1%-5% for light nude base makeup, 2%-6% for transparent color cosmetics, 1%-4% for moisturizing skin care products, 2%-5% for soft hair styling products, adjustable according to formula transparency and mild shaping requirements.
• Q3: Will Polyurethane-2 cause sticky skin or hair?
A3: No. It adopts low-tack elastic molecular structure with super clean film-forming property, no sticky residue on skin and hair surface, refreshing and dry touch all day, effectively avoiding the stickiness of ordinary polyurethane resins.
• Q4: Is it suitable for sensitive skin and mild baby cosmetics?
A4: Yes. High-purity cosmetic grade polymer, no irritating additives, low allergenicity, mild and skin-friendly, compliant with international mild cosmetic standards, perfectly suitable for sensitive skin and mild care cosmetic formulas.
• Q5: Is it suitable for water-phase formula production?
A5: Absolutely. The product has excellent water solubility and dispersibility, can be directly dispersed in water phase without organic solvent, simple production process, stable and uniform water-based system without flocculation.
• Q6: Does it support stable bulk supply and technical services?
A6: Standardized high-end cosmetic grade production with stable batch viscosity and film-forming performance, sufficient inventory, supports long-term bulk supply and global export, and provides professional formula debugging, transparent skin feel and soft styling optimization technical support.
