Silica only acts as a lubricant in general cosmetics.
 
Fumed silica (fumed white carbon black) is an inorganic component, easily compatible with other components of cosmetics, non-toxic and odorless, does not have the above problems, and is white by itself, can be simply colored, especially valuable is fumed dioxide Silicon (gaseous white carbon black) has strong ability to reflect ultraviolet rays and good stability. It does not decompose after being irradiated with ultraviolet rays, does not change color, and does not react with other components in the formula.
 
These outstanding features of fumed silica (fumed white carbon black) have laid a good foundation for the upgrading of sunscreen cosmetics.
 
For cosmetics, it is required to have a strong ability to shield ultraviolet rays, and it is best to protect against both the harm of ultraviolet medium wave (UVB) to the human body and the protection of ultraviolet long wave (UVA). In essence, ultraviolet shielding includes two aspects, one is the absorption of ultraviolet rays as described above, and the other is the reflection of ultraviolet rays. At present, there has been no report of anti-ultraviolet agents developed from the perspective of ultraviolet reflection performance in the world.
 
In the past, organic compounds were mostly used as UV absorbers in sunscreen products. However, after increasing the dosage in order to protect the skin from ultraviolet rays as much as possible, there will be problems such as skin cancer and chemical allergies.
