BUTADIENE/ISOPRENE COPOLYMER

Description

Butadiene/Isoprene Copolymer is a synthetic polymer used in various cosmetic and personal care formulations. This versatile ingredient is formed through the copolymerization of butadiene and isoprene monomers, resulting in a flexible, elastic material with excellent film-forming properties.

In skincare and cosmetic applications, Butadiene/Isoprene Copolymer functions primarily as a film former and viscosity controlling agent. It creates a thin, flexible layer on the skin or hair, providing a smooth, even application and enhancing the longevity of the product. This copolymer is particularly useful in waterproof and long-wearing makeup formulations, such as mascaras, eyeliners, and foundations.

The ingredient's ability to form a protective barrier on the skin helps to lock in moisture and other beneficial ingredients, potentially improving product efficacy. It also contributes to the texture and feel of products, often imparting a silky, smooth sensation upon application.

While generally considered safe for cosmetic use, individuals with sensitive skin should perform patch tests before widespread application, as with any new skincare ingredient. Butadiene/Isoprene Copolymer is not known to penetrate the skin deeply, primarily functioning on the surface level.
