BIS-HEMA POLY(1,4-BUTANEDIOL)-22/DMPA/NEOPENTYL GLYCOL/IPDI COPOLYMER

Description

BIS-HEMA POLY(1,4-BUTANEDIOL)-22/DMPA/NEOPENTYL GLYCOL/IPDI COPOLYMER is a complex synthetic polymer used in advanced skincare and cosmetic formulations. This multifunctional ingredient serves as a film-forming agent, providing a smooth, protective layer on the skin's surface. Its unique chemical structure allows for enhanced water resistance and durability in various skincare products.

The copolymer's composition includes bis-hydroxyethyl methacrylate (BIS-HEMA), poly(1,4-butanediol), dimethylolpropionic acid (DMPA), neopentyl glycol, and isophorone diisocyanate (IPDI). This combination results in a flexible, yet resilient polymer network that aids in improving product texture and application. It is particularly effective in long-wear makeup formulations, sunscreens, and moisturizers where extended product efficacy is desired.

The ingredient demonstrates excellent compatibility with a wide range of cosmetic ingredients, including oils, silicones, and other polymers. It contributes to improved product stability and helps maintain the integrity of formulations under various environmental conditions. 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.
