Sodium thioglycolate is a white powder that has a melting point increased than three hundred°C. It seems as hygroscopic crystals by having an uncomfortable odor attribute with the sulfhydryl group (mercaptans). Thioglycolic acid can 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. It is usually shaped by heating chloroacetic acid with potassium hydrogen sulfide. Thioglycolic acid and its salts and glyceryl esters usually are not recognised to arise naturally.
