BIS-HEMA POLY(1,4-BUTANEDIOL)-9/IPDI COPOLYMER

Description

BIS-HEMA POLY(1,4-BUTANEDIOL)-9/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. Its unique chemical structure allows it to create a flexible, breathable film on the skin's surface, providing long-lasting effects for various cosmetic applications.

The copolymer is composed of bis-hydroxyethyl methacrylate (BIS-HEMA), poly(1,4-butanediol), and isophorone diisocyanate (IPDI). This combination results in a substance with both hydrophilic and hydrophobic properties, enhancing its versatility in formulations. It is particularly effective in water-resistant products, such as sunscreens and long-wear makeup.

In skincare, BIS-HEMA POLY(1,4-BUTANEDIOL)-9/IPDI COPOLYMER helps improve product texture and stability. It can enhance the spreadability of formulations while providing a smooth, non-tacky feel on the skin. The ingredient is generally well-tolerated and considered safe for use in cosmetics at typical concentrations.

Formulators often incorporate this copolymer to improve the overall performance and sensory attributes of products, particularly those requiring extended wear or water resistance. Its film-forming properties can also aid in the even distribution and adherence of active ingredients on the skin surface.
