Chunwang pharmaceutical desiccant uses high-quality silica gel desiccant as raw material, is produced in a dust-free workshop, and the packaging materials are sterilized by ultraviolet light.
Silica gel desiccant is a high-performance adsorption material and is the most widely used desiccant product. Its main component is amorphous silicon dioxide, with the chemical molecular formula mSiO₂·nH₂O. It has a porous network structure, large specific surface area, and high adsorption activity. Our company’s silica gel desiccant is filed with the US FDA. This type of desiccant is currently the only one approved for direct contact with pharmaceuticals.
Silica gel desiccant has good moisture absorption performance, effectively controls environmental humidity, and prevents medicines from dampness and mold. Silica gel desiccant has stable physical properties. Even when completely immersed in water, it maintains its structural stability, does not soften, and does not liquefy. The product is non-toxic, odorless, non-corrosive, and safe for humans and the environment, thus it can directly contact any item.
Due to its chemical inertness and stable properties, silica gel desiccant is widely used in the pharmaceutical industry for product moisture protection, making it an ideal and safe humidity control solution.
The materials and production process of this product meet pharmaceutical-grade standards. Production standards comply with GMP and have passed GMP certification; the product complies with the US FDA standards for pharmaceutical desiccants (File No.: 31936), conforms to the United States Pharmacopeia standard USP41-NF36, and has passed the National Drug Packaging Material Registration (Registration No.: B20190000354).
