Ethylene/Propylene/Styrene/Copolymer

Description

Ethylene/Propylene/Styrene Copolymer is a synthetic ingredient widely used in cosmetic and skincare formulations. This versatile copolymer functions primarily as a thickening agent and emulsion stabilizer, enhancing the texture and consistency of various products. Its molecular structure, composed of ethylene, propylene, and styrene monomers, allows it to form a flexible, three-dimensional network within formulations.

This ingredient is particularly valued for its ability to improve the viscosity and stability of oil-based products, such as lotions, creams, and sunscreens. It helps prevent separation of ingredients and ensures a smooth, uniform application. Ethylene/Propylene/Styrene Copolymer is also known for its film-forming properties, which can contribute to the water-resistance of sunscreens and long-wearing cosmetics.

In skincare formulations, this copolymer is often used in concentrations ranging from 0.1% to 5%, depending on the desired effect and product type. It is generally considered safe for topical use and is compatible with a wide range of cosmetic ingredients. While it doesn't provide direct skin benefits, its role in improving product texture and stability indirectly contributes to the overall efficacy and user experience of skincare products.
