Fumed Silica in Cosmetic applications

In cosmetic products, Fumed silica (AKA silica dimethyl silylate) is a very important additive. It can provide a variety of functions, predominantly focusing on thickening, imparting thixotropic behavior, preventing settling, and providing UV protection while enhancing storage stability. For example, silica dimethyl silylate forms a clear gel in oil. Thickens the oil phase in emulsions by forming oleogel and increases the viscosity and gloss of various oils. It can also improve the effect of lipstick and reduce pigment settling and oil bleeding in lipstick.

By elevating product viscosity and bolstering stability and thixotropy, silica dimethyl silylate ensures improved performance and user experience in various cosmetic formulations.

The inclusion of fumed silica aids in suspending pigments, preventing color fading, and maintaining stable color dispersion throughout the cosmetic product’s shelf life. Additionally, it enhances light reflection and UV-blocking capabilities, thereby heightening the effectiveness of sunscreens in safeguarding the skin from harmful UV rays.

Moreover, silica dimethyl silylate contributes significantly to the overall stability and homogeneity of cosmetic products, preventing undesired phase separation or sedimentation. It optimizes the flow properties of creamy formulations like lotions and emulsions, ensuring smooth application without clumping issue
