BIS-HEMA POLY(DIGLYCOL ADIPATE)/IPDI COPOLYMER
Description
BIS-HEMA POLY(DIGLYCOL ADIPATE)/IPDI COPOLYMER is a complex synthetic ingredient used in various cosmetic and skincare formulations. This copolymer is formed through the reaction of bis-hydroxyethyl methacrylate (BIS-HEMA), poly(diglycol adipate), and isophorone diisocyanate (IPDI). It functions primarily as a film-forming agent and viscosity controller in products such as foundations, sunscreens, and other leave-on skin applications.
The copolymer creates a flexible, breathable film on the skin's surface, which helps to improve the wear and longevity of cosmetic products. It also contributes to the smooth application and even distribution of active ingredients. Due to its film-forming properties, it can enhance the water-resistance of formulations, making it particularly useful in long-wearing and waterproof makeup products.
In skincare, this ingredient can help to lock in moisture and provide a protective barrier against environmental stressors. Its ability to control viscosity allows formulators to achieve desired textures in various products. While generally considered safe for topical use, individuals with sensitive skin or specific allergies should perform patch tests before widespread application.
