The main difference between cosmetic silica and ordinary silica lies in its form and role in cosmetics, which can improve the performance and appearance of products. Cosmetic silica can prevent powdery cosmetics from clumping, improve their dispersibility and stability.

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.
