Potassium Alum - Versatile Inorganic Chemical for Water Treatment, Food & Cosmetic Industries
 
Potassium Alum (CAS 7784-24-9), also known as potash alum or aluminum potassium sulfate dodecahydrate, is a colorless, transparent crystalline compound with weak acidic properties and excellent coagulation capabilities. It is produced through industrial synthesis routes such as double salt crystallization of aluminum sulfate and potassium sulfate, or direct reaction of alumina, sulfuric acid, and potassium sulfate. Our potassium alum products cover food grade, industrial grade, high-purity grade, and crystalline grade, with customized particle sizes and packaging options to meet the diverse needs of water treatment, food processing, cosmetics, leather tanning, and paper manufacturing industries.
 
The core advantage of potassium alum lies in its excellent coagulation and astringent properties. As a coagulant and flocculant in water treatment, it can effectively remove suspended particles, organic matter, and heavy metal ions from wastewater and drinking water, improving water clarity and reducing turbidity. In the food industry, it acts as a firming agent and preservative, helping to maintain the texture of pickled vegetables and fruits, and extending the shelf life of food products. Meanwhile, its astringent properties make it an ideal ingredient in cosmetics and pharmaceuticals, such as antiperspirants, astringents, and mouthwash additives.
