BIS-HEMA PPG-7/SMDI COPOLYMER
Description
BIS-HEMA PPG-7/SMDI Copolymer is a synthetic polymer used in various skincare and cosmetic formulations. This multifunctional ingredient serves as a film-forming agent, emollient, and viscosity controller. Its structure combines bis-hydroxyethyl methacrylate (BIS-HEMA) with polypropylene glycol-7 (PPG-7) and saturated methylene diphenyldiisocyanate (SMDI).
In skincare products, BIS-HEMA PPG-7/SMDI Copolymer creates a thin, flexible film on the skin's surface, which helps to improve product texture and application. This film-forming property also aids in the even distribution of active ingredients and can provide a smooth, non-greasy finish. As an emollient, it helps to soften and moisturize the skin, enhancing its overall appearance and feel.
The copolymer's ability to control viscosity makes it valuable in formulating products with desired consistencies, from lightweight serums to richer creams. It is generally considered safe for use in cosmetics and is compatible with a wide range of other ingredients. However, as with any synthetic polymer, some individuals may experience sensitivity, so patch testing is recommended for those with reactive skin.
