STYRENE/METHYLSTYRENE/INDENE COPOLYMER

Description

STYRENE/METHYLSTYRENE/INDENE COPOLYMER is a synthetic polymer widely used in cosmetic and personal care formulations. This versatile ingredient functions primarily as a film-forming agent and viscosity control substance. Its molecular structure, composed of styrene, methylstyrene, and indene monomers, contributes to its unique properties.

In skincare products, this copolymer creates a protective barrier on the skin, helping to lock in moisture and shield against environmental stressors. It enhances the texture and feel of formulations, providing a smooth, non-tacky finish. The ingredient is particularly effective in long-wearing makeup products, improving adherence and extending wear time.

STYRENE/METHYLSTYRENE/INDENE COPOLYMER is oil-soluble, making it compatible with a wide range of cosmetic ingredients. It exhibits good stability across various pH levels and temperatures, ensuring consistent performance in diverse formulations. The polymer's ability to disperse pigments evenly makes it valuable in color cosmetics.

While generally considered safe for topical use, individuals with sensitive skin should perform patch tests before regular application. This ingredient is not known to penetrate the skin deeply, primarily functioning on the surface layer.
