From Hengyuan desiccant, we learned that the raw material of pharmaceutical desiccant is silica gel. The reason for choosing silica gel desiccant as the raw material is that its main component is silicon dioxide, which is non-toxic, odorless, chemically stable, and has high adsorption performance, good thermal stability, stable chemical properties, and high mechanical strength. Some manufacturers have passed SGS testing, MSDS reports, and EU REACH registration. At the same time, pharmaceutical desiccants must be produced in a million-level sterile workshop to control the content of bacteria such as E. coli.

At Hengyuan, it is understood that, pharmaceutical desiccant its raw material is silica gel.

At the same time, pharmaceutical desiccant must be produced in a million-grade sterile workshop to control the content of bacteria such as E. coli.

　　Silica gel desiccant is a dehumidifier that absorbs moisture from the atmosphere. Its drying principle is to adsorb water molecules into its own structure through physical means or absorb water molecules and change their chemical structure through chemical means, turning into another substance. Silica gel is a highly active adsorbent material, usually prepared by reacting sodium silicate with sulfuric acid, followed by a series of post-treatment processes such as aging and acid washing. Silica gel is an amorphous substance, and its chemical formula is mSiO2.nH2o. It is insoluble in water and any solvent, non-toxic, odorless, chemically stable, and does not react with any substance except strong alkalis and hydrofluoric acid. It meets the characteristics of drug safety and is designated for drug moisture prevention desiccant one of them.
