TRIMETHYLSILOXY/POLYMETHYLSILSESQUIOXANE

Description

TRIMETHYLSILOXY/POLYMETHYLSILSESQUIOXANE is a sophisticated silicone-based ingredient widely used in skincare and cosmetic formulations. This compound belongs to the silicone resin family and is prized for its ability to create a smooth, lightweight film on the skin's surface. Its unique molecular structure combines the properties of both silicone fluids and resins, offering a balance of spreadability and long-lasting effects.

In skincare products, this ingredient functions primarily as a texture enhancer and film-former. It imparts a silky, non-greasy feel to formulations while helping to improve their overall application and wear. The film it creates serves as a barrier, potentially aiding in moisture retention and providing a degree of environmental protection. Additionally, TRIMETHYLSILOXY/POLYMETHYLSILSESQUIOXANE can help to diffuse light on the skin's surface, creating a soft-focus effect that minimizes the appearance of fine lines and imperfections.

This ingredient is particularly valuable in foundations, primers, and other complexion products due to its ability to improve product adherence to the skin and enhance wear time. It's also found in various anti-aging formulations, where its film-forming properties can help to temporarily smooth the skin's appearance.
