white to colourless crystals 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 weld
Potassium aluminium sulfate dodecahydrate is a hydrate resulting from the the formal combination of anhydrous potassium aluminium sulfate with 12 mol eq. of water. It has a role as an astringent, a flame retardant and a mordant. It is a hydrate, an aluminium salt, a metal sulfate and a potassium salt. It contains an aluminium(3+) and a potassium aluminium sulfate.
