Use in Antiperspirants. Aluminum zirconium â or, more precisely, aluminum zirconium tetrachlorohydrex gly â is used in antiperspirants because it has several qualities that reduce sweating. It is absorbed by the skin, where the ions of aluminum and zirconium cause the skin cells to swell.any antiperspirants contain aluminum zirconium. Although some people believe there to be a link between aluminum zirconium and Alzheimer's disease, but scientific research does not support this claim. Aluminum zirconium may be used in antiperspirants because it has qualities that can reduce sweating.
Description: Named for the gemstone in which it was first discovered (which itself is named from the Arabic word meaning gold color), zirconium is a hard, lustrous, gray-white metal. It is common in very cool stars and has been found in the Sun and in meteorites. Zirconium seems to be common in Moon rocks. It is resists water, most acids and bases, so much so that it is used as a shield against corrosive compounds in the chemical industry. It will react with air under certain circumstances.
