A desiccant is a dehydrating agent that absorbs moisture from the atmosphere. The drying principle is to physically adsorb water molecules onto its own structure or to chemically absorb water molecules and change their chemical structure into another substance. 1. Pharmaceutical desiccants are widely used in various fields, such as pharmaceuticals, health products, and diagnostic reagents. Pharmaceutical desiccants require safety, environmental protection, non-toxicity, harmlessness, and ultra-strong hygroscopicity. Pharmaceutical desiccants should obtain the "Drug Packaging Material Registration Certificate" issued by the National Medical Products Administration. Currently, the main desiccant used for pharmaceuticals is silica gel desiccant.

1、 Pharmaceutical desiccant It is widely used in various fields, such as pharmaceuticals, health products, and diagnostic reagents. Pharmaceutical desiccants require safety, environmental protection, non-toxicity, harmlessness, and superior moisture absorption performance. Pharmaceutical desiccants should obtain the "Drug Packaging Material Registration Certificate" issued by the National Medical Products Administration. Currently, the desiccants that can be used for pharmaceuticals are mainly made from silica gel desiccant.

2、The raw material used for pharmaceutical desiccants is silica gel, because silica gel is insoluble in water and any solvent, is non-toxic and tasteless, and has stable chemical properties. Except for strong alkalis and hydrofluoric acid, it does not react with any substance. The chemical composition and physical structure of silica gel determine that it has many characteristics that are difficult to replace by other similar materials.

Pharmaceutical desiccant It is a commonly used moisture-proof and dehumidifying product for pharmaceuticals, usually used for moisture-proofing bottled pharmaceuticals. When pharmaceuticals are stored, the moisture in the air will affect the quality of the pharmaceuticals, so a small amount will be added during packaging. Pharmaceutical desiccant 。
