TRIMETHOXYCAPRYLYLSILANE

Description

Trimethoxycaprylylsilane is a versatile silicone-based ingredient widely used in cosmetic and skincare formulations. This colorless, low-viscosity liquid functions primarily as a surface modifier and binding agent. Its molecular structure consists of a silane core with three methoxy groups and a caprylyl (octyl) chain, providing both hydrophobic and hydrophilic properties.

In skincare products, trimethoxycaprylylsilane acts as an effective dispersing agent for mineral UV filters like titanium dioxide and zinc oxide. It enhances the spreadability of these particles, improving the overall texture and efficacy of sunscreens. The ingredient also serves as a water repellent and film-former, contributing to the long-lasting and water-resistant properties of cosmetic formulations.

Trimethoxycaprylylsilane is known for its ability to improve the adhesion of pigments to the skin, making it valuable in color cosmetics and foundations. It helps create a smooth, even application and enhances the wear time of makeup products. Additionally, this compound can modify the surface of powders, reducing their tendency to agglomerate and improving their flow characteristics.

While generally considered safe for topical use, individuals with silicone sensitivities should exercise caution when using products containing this ingredient.
