Molecule Structure Image



Potassium Aluminium Sulfate Dodecahydrate is the potassium double sulfate of aluminium. It is commonly used in water purification, leather tanning, fireproof textiles, and baking powder. It also has cosmetic uses as a deodorant and as an aftershave treatment. It is a naturally occurring sulfate mineral which typically occurs as encrustations on rocks in areas of weathering and oxidation of sulfide minerals and potassium-bearing minerals. It can be used as a natural deodorant by inhibiting the growth of the bacteria responsible for body odor, dyeing, printing fabrics; manufacture of dyes, lakes, paper, vegetable glue, marble cement, porcelain cement, explosives; in tanning, hardening gelatin, baking powders, purifying water, clarifying sugar, hardening plaster casts; electrolytic copper plating; as catalyst in synthesis of ammonia; as mordant in staining with carmine, eosine, hematoxylin; clarifier.
