POLYSTYRENE/HYDROGENATED POLYISOPENTENE COPOLYMER

Description

POLYSTYRENE/HYDROGENATED POLYISOPENTENE COPOLYMER is a synthetic polymer blend used in cosmetic and skincare formulations. This ingredient combines the properties of polystyrene, a rigid and transparent plastic, with hydrogenated polyisoprene, a flexible and water-resistant compound. The resulting copolymer offers unique benefits in product formulation and application.

This ingredient functions primarily as a film-forming agent and texture enhancer. It creates a smooth, non-tacky film on the skin's surface, which can help improve the wear and durability of makeup and skincare products. The copolymer also contributes to improved spreadability and a silky feel upon application.

In skincare formulations, POLYSTYRENE/HYDROGENATED POLYISOPENTENE COPOLYMER can aid in the even distribution of active ingredients and provide a light, breathable barrier on the skin. This can help protect against environmental stressors and enhance product efficacy. The ingredient is particularly useful in products designed for long-wearing performance, such as foundations, sunscreens, and lip products.

While generally considered safe for topical use, individuals with sensitive skin should perform patch tests before incorporating products containing this copolymer into their routine. As with any synthetic ingredient, potential allergic reactions or skin irritation may occur in rare cases.
