DICYCLOPENTADIENE/ISOPENTENE/ISOPRENE/STYRENE COPOLYMER

Description

Dicyclopentadiene/Isopentene/Isoprene/Styrene Copolymer is a synthetic polymer widely used in cosmetic and skincare formulations. This complex copolymer is composed of four distinct monomers: dicyclopentadiene, isopentene, isoprene, and styrene, which combine to create a versatile ingredient with unique properties.

The copolymer functions primarily as a film-forming agent and viscosity controller in various skincare products. Its molecular structure allows it to form a thin, flexible film on the skin's surface, which can help improve product application and enhance the longevity of cosmetic formulations. This film-forming ability also contributes to water-resistance in sunscreens and long-wearing makeup products.

In addition to its film-forming properties, the copolymer acts as a texture enhancer, providing a smooth, silky feel to formulations. It can improve the spreadability of products and contribute to a more even application. The ingredient is particularly useful in color cosmetics, lip products, and sunscreens, where it can help stabilize pigments and active ingredients.

While generally considered safe for topical use, individuals with sensitive skin should perform patch tests before incorporating products containing this copolymer into their skincare routine.
