strategically placed alongside the powder to maintain a dry environment. These desiccants work by adsorbing excess
moisture from the air, thereby reducing the risk of hydrolysis reactions that could compromise the powder's chemical
structure and efficacy.

In addition to desiccants, the use of dehumidifiers in storage areas provides an additional layer of protection against
ambient humidity. These devices actively remove moisture from the air, creating a controlled environment that is less
