BUTENE/PROPYLENE COPOLYMER
Description
Butene/Propylene Copolymer is a synthetic polymer derived from the copolymerization of butene and propylene monomers. This versatile ingredient serves multiple functions in skincare and cosmetic formulations, primarily as a film-forming agent, viscosity controller, and emollient. Its molecular structure allows it to create a flexible, breathable barrier on the skin's surface, helping to lock in moisture and protect against environmental stressors.
In skincare products, Butene/Propylene Copolymer enhances texture and improves the spreadability of formulations, contributing to a smooth, even application. It also aids in the uniform distribution of active ingredients throughout the product. The copolymer's film-forming properties make it particularly useful in long-wearing makeup formulations, such as foundations and mascaras, where it helps to improve adherence and longevity.
This ingredient is generally considered safe for topical use and is compatible with a wide range of other cosmetic ingredients. It is non-comedogenic, making it suitable for various skin types, including acne-prone skin. Butene/Propylene Copolymer is often used in concentrations ranging from 0.5% to 10%, depending on the desired effect and product type.
