ISOBUTYLENE/ISOPRENE COPOLYMER
Description
Isobutylene/Isoprene Copolymer is a synthetic polymer widely used in skincare and cosmetic formulations. This versatile ingredient is formed by combining isobutylene and isoprene monomers, resulting in a clear, colorless, and odorless substance. Its primary function is to act as a film-forming agent, creating a protective barrier on the skin or hair surface.
In skincare products, Isobutylene/Isoprene Copolymer enhances the texture and improves the spreadability of formulations. It contributes to the water-resistant properties of sunscreens and long-wearing makeup, helping to maintain product efficacy and appearance throughout the day. The polymer also aids in the even distribution of active ingredients and pigments within a formulation.
This ingredient is generally considered safe for use in cosmetics and is non-comedogenic, making it suitable for various skin types. It is inert and does not react with other ingredients, ensuring stability in complex formulations. Isobutylene/Isoprene Copolymer is particularly beneficial in products designed for long-lasting wear or those requiring resistance to water and sebum.
