Calcium Chloride Dihydrate (CaCl₂·2H₂O) is a hydrated form of calcium chloride, appearing as white crystalline granules or flakes containing two molecules of water of crystallization. It is highly soluble in water and exhibits strong hygroscopic and deliquescent properties. This compound is widely used in industrial, pharmaceutical, food, and agricultural sectors due to its moisture absorption, de-icing, dust control, and calcium supplementation capabilities. Compared to anhydrous calcium chloride, the dihydrate form has lower hygroscopicity but is easier to handle and store.

Aluminum hydroxide
Aluminum Hydroxide, chemically known as Al(OH)₃, is a white, odorless, and odorless powder or gelatinous substance. It is widely used in pharmaceuticals as an antacid to neutralize stomach acid and relieve indigestion and heartburn. Beyond healthcare, aluminum hydroxide is a crucial component in water purification, fire retardants, and as a precursor or filler in various industrial applications. It functions as a flame retardant by releasing water upon heating, thus cooling the material and diluting flammable gases. Due to its amphoteric nature, it can react both as an acid and base, enhancing its versatility. Aluminum hydroxide is often utilized in manufacturing aluminum salts and in producing aluminum oxide.
Borax Pentahydrate
Borax Pentahydrate (sodium tetraborate pentahydrate) is an inorganic compound and a hydrated form of borax. It typically appears as colorless to white crystalline granules or powder. This compound contains five molecules of water of crystallization per formula unit, distinguishing it from other borax hydrates such as the decahydrate form. Borax Pentahydrate is widely used across industries including detergents, glass production, agriculture, and cosmetics, valued for its buffering capacity, emulsification, and antiseptic properties.
