BIS-HEMA POLY(1,4-BUTANEDIOL)-14/IPDI COPOLYMER

Description

BIS-HEMA POLY(1,4-BUTANEDIOL)-14/IPDI COPOLYMER is a synthetic film-forming polymer used in various cosmetic and skincare formulations. This complex ingredient functions as a binding agent and texture enhancer, providing a smooth, even application in products such as foundations, concealers, and other color cosmetics.

The polymer is created through the reaction of bis-hydroxyethyl methacrylate (BIS-HEMA) with a copolymer of 1,4-butanediol and isophorone diisocyanate (IPDI). This combination results in a flexible, water-resistant film when applied to the skin. The "14" in its name indicates the average number of repeating units in the polymer chain.

BIS-HEMA POLY(1,4-BUTANEDIOL)-14/IPDI COPOLYMER offers several benefits in skincare formulations, including improved product stability, enhanced wear time, and resistance to transfer. It helps create a barrier on the skin, potentially aiding in moisture retention and protecting against environmental stressors.

While generally considered safe for cosmetic use, individuals with sensitive skin or a history of allergic reactions to similar compounds should perform a patch test before using products containing this ingredient. As with any synthetic polymer, long-term safety studies are ongoing to fully understand its impact on skin health and the environment.
