HYDROGENATED STYRENE/ISOPRENE COPOLYMER

Description

Hydrogenated Styrene/Isoprene 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 polymerization of styrene and isoprene monomers, followed by a hydrogenation process. This results in a clear, colorless substance with excellent adhesion properties and resistance to water and oils.

In skincare applications, Hydrogenated Styrene/Isoprene Copolymer helps create a protective barrier on the skin's surface, which can aid in moisture retention and provide a smooth, even application of products. It is particularly beneficial in long-wearing makeup formulations, such as foundations and mascaras, where it enhances durability and transfer resistance.

The ingredient is generally considered safe for use in cosmetics and is compatible with a wide range of other formulation components. Its low molecular weight allows for easy spreadability without feeling heavy or greasy on the skin. While not actively addressing specific skin concerns, Hydrogenated Styrene/Isoprene Copolymer plays a crucial role in improving the overall performance and user experience of many skincare and cosmetic products.
