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

Description

BIS-HPA POLY(1,4-BUTANEDIOL)-9/GLYCOL/IPDI COPOLYMER is a synthetic polymer used in various skincare and cosmetic formulations. This multifunctional ingredient serves as a film-forming agent, enhancing the texture and application of products while providing a protective barrier on the skin's surface.

The copolymer is composed of three main components: bis-hydroxypolyacrylamide (BIS-HPA), 1,4-butanediol, and isophorone diisocyanate (IPDI). This unique combination results in a flexible, yet durable film when applied to the skin. It helps to improve the water resistance of formulations, making it particularly useful in long-wearing makeup and sunscreen products.

In skincare applications, this copolymer can contribute to improved moisture retention by creating an occlusive layer that reduces transepidermal water loss. It also aids in the even distribution of active ingredients across the skin's surface, potentially enhancing their efficacy.

The ingredient is generally well-tolerated by most skin types and is often used in products designed for sensitive skin. However, as with any synthetic polymer, patch testing is recommended for individuals with known sensitivities. Its versatility and performance make it a valuable component in modern skincare and cosmetic formulations.
