In liquid products, silica can play a role in thickening and thixotropic properties, while in powdered products, it can improve fluidity and storage stability, thereby playing an anti caking role. Meanwhile, due to its high specific surface area, silica can also act as an adsorbent and carrier, capable of adsorbing gases, liquids, and solids.

Cosmetic silica is a non-toxic white powdery substance with various characteristics, such as strong adsorption ability. It can be used as an anti caking agent and thickener in cosmetics, improving storage stability and dispersion of powdered products, and is widely used.
