GLYCIDOXYPROPYL POLYSILSESQUIOXANE

Description

GLYCIDOXYPROPYL POLYSILSESQUIOXANE is an advanced silicone-based ingredient widely used in skincare and cosmetic formulations. This complex compound belongs to the family of silsesquioxanes, known for their unique three-dimensional cage-like molecular structure. Its primary function is to act as a film-former and surface modifier, providing a smooth, even application and long-lasting wear in various products.

The glycidoxypropyl functional group attached to the silsesquioxane core enhances the ingredient's compatibility with other formulation components and improves its adhesion to the skin. This results in better product stability and increased efficacy of active ingredients. GLYCIDOXYPROPYL POLYSILSESQUIOXANE offers excellent water resistance, making it particularly valuable in sunscreens and long-wear makeup products.

In skincare, it helps create a protective barrier on the skin's surface, reducing transepidermal water loss and improving overall skin hydration. Its film-forming properties also contribute to a soft-focus effect, temporarily minimizing the appearance of fine lines and wrinkles. While generally considered safe for topical use, it's important to note that some individuals may experience sensitivity to silicone-based ingredients. As with any skincare component, patch testing is recommended before widespread use.
