STEARYLVINYL ETHER/MA COPOLYMER

Description

STEARYLVINYL ETHER/MA COPOLYMER is a synthetic copolymer used in various skincare and cosmetic formulations. This ingredient is primarily employed as a film-forming agent and emulsion stabilizer, contributing to the texture and longevity of products. The copolymer is composed of stearyl vinyl ether and maleic anhydride (MA) units, which combine to create a versatile compound with both hydrophobic and hydrophilic properties.

In skincare applications, STEARYLVINYL ETHER/MA COPOLYMER helps create a smooth, even film on the skin's surface, enhancing the feel and appearance of products. It aids in the uniform distribution of active ingredients and can improve the water resistance of formulations. The ingredient's film-forming capabilities also contribute to the long-wearing properties of makeup and sunscreen products.

As an emulsion stabilizer, this copolymer helps maintain the integrity of oil-in-water or water-in-oil formulations, preventing separation and ensuring product consistency over time. It is generally considered safe for use in cosmetics and is compatible with a wide range of other ingredients. However, as with any synthetic polymer, some individuals may experience sensitivity, so patch testing is recommended for those with reactive skin.
