BIS-HEMA POLYNEOPENTYL GLYCOL ADIPATE/IPDI COPOLYMER

Description

BIS-HEMA POLYNEOPENTYL GLYCOL ADIPATE/IPDI COPOLYMER is a synthetic polymer used in cosmetic and skincare formulations. This complex ingredient functions primarily as a film-forming agent and viscosity controller, contributing to the texture and stability of various products.

The copolymer is composed of bis-hydroxyethyl methacrylate (BIS-HEMA), polyneopentyl glycol adipate, and isophorone diisocyanate (IPDI). This unique combination results in a molecule that forms a flexible, breathable film on the skin's surface. This film can help to lock in moisture, improve product adherence, and provide a smooth, even application.

In skincare formulations, it is often used in foundations, sunscreens, and other leave-on products. The copolymer's film-forming properties can enhance the water resistance of sunscreens and improve the longevity of makeup. Additionally, its ability to control viscosity helps in creating stable emulsions and suspensions.

While generally considered safe for cosmetic use, as with any synthetic ingredient, some individuals may experience sensitivity. It is non-comedogenic and suitable for a wide range of skin types. The copolymer's performance in formulations makes it a valuable ingredient in modern skincare and cosmetic products.
