Ammonium aluminium sulfate, also known as ammonium alum is a white crystalline double sulfate usually encountered as the dodecahydrate, formula (NH4)Al(SO4)2·12H2O. It is used in water purification, in vegetable glues, in porcelain cements, in natural deodorants and in tanning, dyeing and in fireproofing textiles.[4] It is also an acidity regulator in its use as a food additive (E523). The dodecahydrate occurs naturally as the rare mineral tschermigite.[1][5]
No human or ecological (for reduced concentrations) toxicity registered.[6]
Uses
The pH of the solution resulting from the topical application of ammonium alum with perspiration is typically in the slightly acid range, from 4 to 5.[7] It is a popular deodorant. A 120 gram stone lasts for at least a year of daily usage – much longer than other deodorants and antiperspirants. It is also hypoallergenic and non-staining.[ref. needed] Potassium alum is also used for this purpose.
