HYDROGENATED BUTADIENE/ISOPRENE/STYRENE COPOLYMER

Description

Hydrogenated Butadiene/Isoprene/Styrene Copolymer is a synthetic polymer used in various cosmetic and skincare formulations. This ingredient functions primarily as a film-forming agent and viscosity controller, providing texture and stability to products. The copolymer is created through the polymerization of butadiene, isoprene, and styrene monomers, followed by hydrogenation to enhance its stability and reduce reactivity.

In skincare applications, this copolymer forms a flexible, breathable film on the skin's surface, helping to lock in moisture and protect against environmental stressors. Its film-forming properties make it particularly useful in long-wearing makeup formulations, sunscreens, and other products requiring extended durability. The ingredient also contributes to the smooth application and even distribution of active ingredients within a formulation.

Hydrogenated Butadiene/Isoprene/Styrene Copolymer is generally considered safe for cosmetic use and is non-comedogenic, making it suitable for a wide range of skin types. Its molecular structure allows for good compatibility with various other cosmetic ingredients, enhancing the overall stability and performance of formulations. This versatile polymer can be found in products such as foundations, lip products, mascaras, and skincare serums.
