Aluminium potassium sulfate dodecahydrate CAS#7784-24-9

Aluminum is the most commonly available element in homes and workplaces. Aluminum is readily available for human ingestion through the use of food additives, antacids, buffered aspirin, astringents, nasal sprays, and antiperspirants; from drinking water; from automobile exhaust and tobacco smoke; and from using aluminum foil, aluminum cookware, cans, ceramics, and fi reworks. Workers who are at risk for toxicity are those in refi neries, foundries and also welders and grinders.A group of double salts withthe formula A2SO4.B2(SO4)3.24H2O,where A is a monovalent metal and Ba trivalent metal. The original examplecontains potassium and aluminium(called potash alum orsimply alum); its formula is oftenwritten AlK(SO4)2.12H2O (aluminiumpotassium sulphate-12-water). Ammoniumalum is AlNH4(SO4)2.12H2O,chrome alum is KCr(SO4)2.12H2O, etc.The alums are isomorphous and canbe made by dissolving equivalentamounts of the two salts in waterand recrystallizing.

Product Application of Aluminium potassium sulfate dodecahydrate CAS#7784-24-9

Potassium alum precipitates proteins and is a powerful astringent. The ability to precipitate proteins is utilized in the manufacture of vaccines, where purified proteins are coprecipitated with and adsorbed onto potassium alum.
Potassium alum is often included in preparations used as mouthwashes or gargles and in dermatological preparations, and it may be used as a topical hemostatic, either as a solid or as a solution. Intravesical instillation of potassium alum, typically as a 1% solution, has been used for hemorrhagic cystitis.
