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

Description

BIS-HEMA Poly(1,4-butanediol)-22/IPDI Copolymer is a synthetic polymer used in skincare and cosmetic formulations. This complex ingredient functions primarily as a film-forming agent and viscosity controller. Its structure consists of bis-hydroxyethyl methacrylate (BIS-HEMA) units combined with poly(1,4-butanediol) and isophorone diisocyanate (IPDI).

In skincare products, this copolymer creates a thin, flexible film on the skin's surface, which helps to lock in moisture and protect against environmental stressors. It also contributes to the smooth application and even distribution of active ingredients. The film-forming properties make it particularly useful in long-wearing makeup formulations and sunscreens, enhancing their resistance to water and wear.

The viscosity-controlling aspect of BIS-HEMA Poly(1,4-butanediol)-22/IPDI Copolymer allows formulators to achieve desired textures in various products, from lightweight serums to rich creams. This versatility makes it a valuable ingredient across a wide range of skincare and cosmetic applications. While generally considered safe for topical use, individuals with sensitive skin or specific polymer allergies should perform patch tests before widespread application.
