Sodium thioglycolate is actually a white powder which has a melting point better than 300°C. It seems as hygroscopic crystals with the unpleasant odor characteristic in the sulfhydryl group (mercaptans). Thioglycolic acid could be organized via the motion of sodium sulfhydrate on sodium chloroacetate and by electrolysis of dithioglycollic acid from sodium sulfide and sodium chloroacetate. It is additionally formed by heating chloroacetic acid with potassium hydrogen sulfide. Thioglycolic acid and its salts and glyceryl esters are not regarded to happen By natural means. Sodium thioglycolate is used within the cosmetic industry as an antioxidant, depilating agent, hair waving/straightening agent, and minimizing agent. Its Main beauty use is in depilatories.
TGA is used as being a chemical depilatory and is still used as such, specifically in salt types, together with calcium thioglycolate and sodium thioglycolate. TGA is definitely the precursor to ammonium thioglycolate, that's used for permanents. TGA and its derivatives split the disulfide bonds during the cortex of hair.
