BIS-HPMA POLY(1,4-BUTANEDIOL)-9/TMDI COPOLYMER

Description

BIS-HPMA Poly(1,4-butanediol)-9/TMDI Copolymer is a synthetic polymer used in skincare and cosmetic formulations. This ingredient functions primarily as a film-forming agent and emollient, providing a smooth, protective layer on the skin's surface. Its unique structure allows it to create a flexible, breathable film that helps lock in moisture while still allowing the skin to respire.

The copolymer is composed of bis-hydroxypropyl methacrylate (BIS-HPMA), 1,4-butanediol, and trimethylhexamethylene diisocyanate (TMDI). This combination results in a polymer with both hydrophilic and hydrophobic properties, enabling it to interact effectively with both water and oil-based ingredients in formulations.

In skincare products, BIS-HPMA Poly(1,4-butanediol)-9/TMDI Copolymer can improve texture, enhance product stability, and contribute to a more even application. It is particularly useful in long-wearing cosmetics, sunscreens, and moisturizers where a durable, yet comfortable film is desired. The polymer also aids in the uniform dispersion of other active ingredients throughout the product.

While generally considered safe for topical use, as with any synthetic ingredient, patch testing is recommended for individuals with sensitive skin or a history of allergic reactions to cosmetic ingredients.
