BIS-HEMA IPDI/PEG-4 COPOLYMER

Description

BIS-HEMA IPDI/PEG-4 Copolymer is a synthetic polymer used in cosmetic and skincare formulations. This ingredient functions as a film-forming agent and viscosity controller, contributing to the texture and stability of various products. It is composed of bis-hydroxyethyl methacrylate (BIS-HEMA), isophorone diisocyanate (IPDI), and polyethylene glycol (PEG-4).

The copolymer creates a flexible, breathable film on the skin's surface, which can help improve the wear and longevity of makeup products. It also aids in the even distribution of active ingredients and pigments within formulations. In skincare products, it can enhance the delivery of beneficial compounds and provide a smooth, non-tacky feel.

BIS-HEMA IPDI/PEG-4 Copolymer is particularly useful in water-resistant formulations, as it helps create a barrier against moisture. This property makes it valuable in sunscreens, long-wear foundations, and other products designed to withstand environmental factors.

While generally considered safe for topical use, individuals with sensitive skin or known allergies to any of its components should perform a patch test before widespread application. As with any cosmetic ingredient, its concentration in formulations is regulated to ensure safety and efficacy.
