Functions
Anhydrous aluminium zirconium tetrachlorohydrex gly functions by diffusing into the sweat gland and forming a colloidal "plug" which limits the flow of sweat to the skin surface. The plug is gradually broken down and normal sweating resumes.
Clothing stains
When mixed with sweat, aluminium zirconium tetrachlorohydrex gly is thought to stain clothing with a yellowish tint. It can also cause a stiffening of the affected areas of clothing. If excessive amounts of aluminium zirconium tetrachlorohydrex gly mixed with sweat come in contact with a material, bleach marks may develop.
