AlSalt

AlSalt is not a single, universally defined substance. In chemistry, the term is sometimes used ambiguously to refer to aluminum-based salts—compounds containing the aluminum ion Al3+ paired with various anions. It may also denote a specific product name or brand in industrial contexts. As a class, aluminum salts include well-known compounds such as aluminum sulfate, aluminum chloride, aluminum nitrate, and the mineral alum, potassium aluminum sulfate.

Most aluminum salts are solids that dissolve or hydrolyze in water to form aluminum hydroxide species. The solutions are typically acidic and can act as coagulants in water treatment, helping to remove suspended solids.

Aluminum salts are produced by reacting sources of aluminum (such as aluminum hydroxide or alumina) with acids or with base-neutralization steps, or by processing aluminum-bearing minerals to isolate the corresponding salts.

Key uses include water purification, paper production, textile mordants, cosmetics as antiperspirants (aluminum chlorohydrate and related compounds), and medicines where aluminum hydroxide or aluminum phosphate act as antacids or adjuvants in vaccines.

Aluminum salts can be irritants and their solubility and hydrolysis behavior influence exposure risk. Regulatory agencies provide guidelines on handling, use in consumer products, and environmental disposal. As with many chemicals, prudent handling and adherence to product-specific safety data sheets are recommended.
