Calcium chloride for testing moisture absorption rate
Desiccant simply refers to a substance that removes moisture from the moist products. A commonly used desiccant is the calcium chloride, which chemically reacts with water molecules to absorb moisture from the surrounding atmosphere and transform it into a gel, to achieve an adsorption effect. The moisture absorption rate of calcium chloride is 8-15 times that of ordinary desiccants.
Frequently Asked Questions ?
Calcium chloride is used as a desiccant in pharmaceutical packaging to absorb moisture and maintain the quality of drugs and other sensitive products.
Calcium chloride is hygroscopic, meaning it can attract and hold water molecules from the surrounding environment. This property makes it effective in reducing the moisture content in packaging and preventing the degradation of sensitive products.
Yes, calcium chloride is generally recognized as safe (GRAS) by the FDA for use in food and pharmaceuticals. It is non-toxic, non-corrosive, and non-flammable.
There are various forms of calcium chloride desiccants available, including sachets, canisters, and strips. These desiccants are designed to be compatible with different types of packaging and application requirements.
