For cosmetics, it is required for UV shielding ability, UV protection is best both wave (UVB) on the human body, also on the long-wave ultraviolet (UVA) from the protective effect. UV shielding essentially consists of two aspects, first, the absorption of ultraviolet light as described earlier, on the other hand is a reflection of ultraviolet rays. 

 In the past, more use of sunscreen products, organic compounds as UV absorbers, but there is not such as to protect the skin as possible increased exposure to ultraviolet light and after adding the amount will increase the incidence of skin cancer and chemical allergies and other issues, the nano-Si02 as the inorganic component easy compatibility with other components of cosmetics, non-toxic, tasteless, there is no such problem, and their white color can easily be especially valuable is that nano-Si02 strong UV reflection, good stability, UV irradiation was not decomposition, do not change, nor with other components in the formula from a chemical reaction. These outstanding features of nano-Si02 as the upgrading of sunscreen cosmetics laid a good foundation. 

 Spherical silica, particle size of about 1-9um, can be used in lipstick, face powder, foundation cream, make-up supplies. It is the process through an innovative method of manufacturing is made available to a narrow size distribution, larger surface area, has the following unique properties: 
 It's smaller average particle size to determine their good smoothness; 
 Its narrow size distribution to determine its good liquidity and touch; 
 It is larger than the volume to determine their cosmetic formulations and more economical. 
 Its large surface area to have a good absorption of sweat, spices, nutrients and protective chemicals. 
 Applied in a liquid thickening and thixotropic play, play suspended in the liquid and re-dispersion of powder in the powder products such as mobility and storage can improve the stability of which play the role of anti-caking , because the characteristics of high specific surface area and the carrier can also function as an adsorbent, can absorb gas, liquid and solid substances. Used in lipstick, face powder, foundation cream and other formulations have the following characteristics: 
 Good dispersion and compatibility of oil phase; 
 Good affinity to the skin; 
 Good hydrophobicity, makeup can enhance sustainability.
