Therefore, many products do not need to put a desiccant if they have been treated with moisture-proof when they are packaged. Of course, no matter how well the moisture-proof treatment is done, there will be some moisture in the packaging air. If the quality requirements are stricter, a desiccant will still be added to prevent moisture. Medicinal desiccants are generally silica gel desiccants, which are non-toxic, tasteless, chemically stable, and do not react with any substances except strong alkalis and acids. The product quality fully meets ROHS, REACH and other environmental protection requirements, and meets the Chinese chemical standard HG/T2765-2005. It does not contain harmful substances such as DMF (dimethyl fumarate). At the same time, silica gel is also a desiccant that has passed the US FDA certification and can be used in direct contact with medicines and food.
