  • Thioglycolates are used in cosmetic hair-care products especially permanent waving products as they weaken the keratin structure by the opening of the cystine disulfide linkages.
  • In addition to hair-waving application, they are used as depilating agents to remove unwanted body hair. The break-down of disulfide bonds in the cortex by thioglycolates either rearranges (permanent waving) or entirely destroys (depilating) hair structure.
  • As an antioxidant application in cosmetics, thioglycolates protect the product itself not the skin against oxidative reactions promoted by ultraviolet radiation or oxygen.
