BUTYLENE/ETHYLENE/STYRENE COPOLYMER

Description

Butylene/Ethylene/Styrene Copolymer is a synthetic polymer used in various skincare and cosmetic formulations. This versatile ingredient functions primarily as a film-forming agent and thickener, contributing to the texture and stability of products. Its unique molecular structure, composed of butylene, ethylene, and styrene monomers, allows it to form a flexible, breathable film on the skin's surface.

In skincare applications, this copolymer enhances the spreadability of formulations while providing a smooth, non-greasy feel. It aids in the even distribution of active ingredients and can improve the water resistance of sunscreens and long-wear makeup products. The film-forming properties also help to lock in moisture, potentially benefiting dry or dehydrated skin types.

Butylene/Ethylene/Styrene Copolymer is compatible with a wide range of cosmetic ingredients, making it suitable for use in various product types, including creams, lotions, and gels. It is generally considered safe for topical use and is non-comedogenic, meaning it is unlikely to clog pores. However, as with any synthetic ingredient, some individuals may experience sensitivity, so patch testing is recommended for those with reactive skin.
