• Description: Ammonium thioglycolate, also known as perm salt, is the chemical compound with the formula HSCH2CO2NH4. Being the salt of a weak acid and weak base, ammonium thioglycolic acid exists in solution as an equilibrium mixture of the salt itself as well as the free carboxylic acid thioglycolic acid (HSCH2CO2H) and ammonia : HSCH2COO- + NH4+ ? HSCH2COOH + NH3.
• Uses: acts as a reducing agent in permanent-waving formulations for hair treatment and in shrink-resistant treatment of wool. Ammonium thioglycolate is contained in permanent waves solutions and causes contact dermatitis in hairdressers. Solutions of various strengths are used for hair waving and for hair removal.
