Cosmetic Silicon Dioxide

◆Description of products

The Silicon Dioxide added in the sunscreen products shows high ultraviolet-ray reflection ability. It also shows good stability, for it will not decompose or change color when exposed to UV, and it will not react with other components in the formulation.

◆Application scopes

Silicon Dioxide serves as the main reinforcing filler in Cosmetic

What is the Silicon Dioxide

Silicon dioxide, also known as silica, silicic acid or silicic acid anydride is an oxide of silicon with the chemical formula SiO₂, most commonly found in nature as quartz and in various living organisms.In many parts of the world, silica is the major constituent of sand. Silica is one of the most complex and most abundant families of materials, existing as a compound of several minerals and as synthetic product. Notable examples include fused quartz, fumed silica, silica gel, and aerogel silica. It is used in structural materials, cosmetic,microelectronics (as an electrical insulator), and as components in the food and pharmaceutical industries.
