HYDROGENATED BUTYLENE/ETHYLENE/STYRENE COPOLYMER

Description

Hydrogenated Butylene/Ethylene/Styrene Copolymer is a synthetic polymer widely used in skincare and cosmetic formulations. This versatile ingredient functions primarily as a film-forming agent and viscosity controller, contributing to the texture and stability of various products. The copolymer is created through the hydrogenation of butylene, ethylene, and styrene monomers, resulting in a stable, non-reactive compound.

In skincare applications, Hydrogenated Butylene/Ethylene/Styrene Copolymer forms a protective barrier on the skin's surface, helping to lock in moisture and prevent transepidermal water loss. This property makes it particularly useful in products designed for dry or sensitive skin. The ingredient also enhances the spreadability and smooth application of formulations, improving the overall user experience.

Due to its film-forming capabilities, this copolymer is often incorporated into long-wearing makeup products, such as foundations and lipsticks, to increase their durability and resistance to transfer. It is generally considered safe for use in cosmetics and has not been associated with significant skin irritation or allergic reactions. However, as with any synthetic ingredient, individual sensitivities may vary, and patch testing is recommended for those with particularly reactive skin.
