Thioglycolic acid might be well prepared because of the action of sodium sulfhydrate on sodium chloroacetate and by electrolysis of dithioglycollic acid from sodium sulfide and sodium chloroacetate. Additionally it is shaped by heating chloroacetic acid with potassium hydrogen sulfide. Thioglycolic acid and its salts and glyceryl esters are not recognised to manifest By natural means. Sodium thioglycolate is used inside the beauty industry being an antioxidant, depilating agent, hair waving/straightening agent, and minimizing agent. Its Major beauty use is in depilatories.
