BUTYLENE/ETHYLENE/PROPYLENE COPOLYMER
Description
Butylene/Ethylene/Propylene Copolymer is a synthetic polymer composed of butylene, ethylene, and propylene monomers. This versatile ingredient functions primarily as a film-forming agent and viscosity controller in cosmetic and skincare formulations. Its unique structure allows it to form a flexible, breathable film on the skin's surface, providing both protection and a smooth, non-greasy feel.
In skincare products, this copolymer enhances texture and improves the spreadability of formulations, making them easier to apply evenly. It also aids in the even distribution of active ingredients across the skin. The film-forming properties help to lock in moisture and create a barrier against environmental stressors, potentially improving the longevity of other beneficial ingredients in the formulation.
Butylene/Ethylene/Propylene Copolymer is particularly useful in sun care products, where it can contribute to water resistance and improve the substantivity of UV filters. In makeup formulations, it can enhance wear time and resist transfer. This ingredient is generally well-tolerated by most skin types and is considered safe for use in cosmetics at typical concentrations. It's non-comedogenic, making it suitable for use in products designed for acne-prone skin.
