Silica gel is a highly active adsorption material, the main component is silicon dioxide, its chemical formula is mSiO2·nH2O. It is usually prepared by the reaction of sodium silicate and sulfuric acid, and by a series of post-treatment processes such as aging and acid bubble. The chemical properties of silica gel are stable, do not burn, and do not react with any substance except strong alkali and hydrofluoric acid.

Silica gel has non-toxic, tasteless, non-corrosive, pollution-free characteristics, so it can be in direct contact with any item.
