Hydrogenated Styrene/Isoprene Copolymer

Description

Hydrogenated Styrene/Isoprene Copolymer is a synthetic polymer widely used in skincare and cosmetic formulations. This ingredient is formed by the hydrogenation of a copolymer made from styrene and isoprene monomers. The hydrogenation process enhances stability and reduces reactivity, making it suitable for various skincare applications.

In formulations, Hydrogenated Styrene/Isoprene Copolymer functions primarily as a film-forming agent and viscosity controller. It creates a flexible, water-resistant film on the skin's surface, which can improve the longevity and wear of cosmetic products. This property is particularly beneficial in long-wearing makeup and sunscreen formulations.

The ingredient also contributes to the texture and feel of products, providing a smooth, silky sensation upon application. It can enhance the spreadability of formulations and help to evenly distribute active ingredients across the skin. Hydrogenated Styrene/Isoprene Copolymer is generally considered safe for use in cosmetics and is compatible with a wide range of other ingredients.

Due to its film-forming capabilities, this copolymer can assist in reducing transepidermal water loss, potentially contributing to improved skin hydration. It's commonly found in foundations, lip products, sunscreens, and various other skincare and cosmetic items.
