 Due to the relatively high specific surface area and strong surface polarity of fumed silica, in powder systems, the high adsorption of fumed silica can be used to prevent the agglomeration of the system. The particle size is relatively small. After being dispersed in the powder system, it covers the surface of the system particles. During the use process, it can play the role of internal lubrication and increase the fluidity of the system. For example, in toner powder, after adding fumed silica, it can absorb some moisture, so as to obtain a dry effect, and can effectively prevent agglomeration and improve fluidity. The dosage is generally 0.5 to 6%. In addition, using the high specific surface area, small particle size and high adsorption of fumed silica, it can be used to adsorb essences and be used in powdered cosmetics, and it can also control the release rate of essences. In addition, in powdered cosmetics, such as facial care products, antiperspirants, etc., fumed silica can absorb too much oil and water, and obtain good results.

At present, there are many kinds of products of foreign fumed silica production enterprises, all of which are developed into special products in different fields, and the products are very functional. With the improvement of the production level of fumed silica and people's understanding of fumed silica With the increase of fumed silica, the application of fumed silica in daily necessities will become more and more extensive.
