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.

Another important characteristic of silicon dioxide is its strong ability to reflect ultraviolet light, good stability, and ability to not decompose or change color after being exposed to ultraviolet radiation. It also does not react chemically with other components in the formula. Therefore, silica has played a good foundational role in the upgrading and replacement of sunscreen cosmetics.
