BIS-POLY(1,4-BUTANEDIOL)-9/TMDI/IPDI COPOLYMER
Description
BIS-POLY(1,4-BUTANEDIOL)-9/TMDI/IPDI COPOLYMER is a synthetic polymer used in various skincare and cosmetic formulations. This complex ingredient functions primarily as a film-forming agent and viscosity controller. Its unique molecular structure, composed of butanediol, trimethylhexamethylene diisocyanate (TMDI), and isophorone diisocyanate (IPDI), allows it to create a flexible, breathable film on the skin's surface.
This copolymer is particularly effective in water-resistant formulations, making it valuable for sunscreens, long-wear makeup, and outdoor skincare products. It enhances the durability and longevity of these formulations without compromising skin comfort. The ingredient also contributes to improved texture and spreadability of products, ensuring even application and coverage.
In skincare, BIS-POLY(1,4-BUTANEDIOL)-9/TMDI/IPDI COPOLYMER can help to lock in moisture and other beneficial ingredients, potentially enhancing their efficacy. Its film-forming properties may also provide a temporary smoothing effect on the skin's surface, minimizing the appearance of fine lines and imperfections. While generally well-tolerated, as with any synthetic polymer, patch testing is recommended for individuals with sensitive skin or a history of allergic reactions to cosmetic ingredients.
