ISOPROPYLIDENEDIPHENYL BISOXYHYDROXYPROPYL METHACRYLATE/TMDI COPOLYMER

Description

ISOPROPYLIDENEDIPHENYL BISOXYHYDROXYPROPYL METHACRYLATE/TMDI COPOLYMER is a synthetic polymer used in various skincare and cosmetic formulations. This complex compound functions primarily as a film-forming agent and viscosity controller. Its molecular structure allows it to create a thin, flexible layer on the skin's surface, which can help improve the texture and appearance of products while providing a smooth, even application.

The copolymer is composed of isopropylidenediphenyl bisoxyhydroxypropyl methacrylate units combined with trimethylhexamethylene diisocyanate (TMDI). This unique composition contributes to its ability to form stable emulsions and enhance the overall stability of formulations. In skincare products, it can help improve moisture retention by creating a barrier that reduces transepidermal water loss.

The ingredient is particularly useful in long-wearing makeup formulations, such as foundations and concealers, where it aids in improving product adherence to the skin and enhancing durability. It also contributes to the water-resistance of sunscreens and other protective skincare products. 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.
