Sodium thioglycolate can be a white powder having a melting point bigger than 300°C. It seems as hygroscopic crystals using an uncomfortable odor characteristic in the sulfhydryl team (mercaptans). Thioglycolic acid may be geared up via the action of sodium sulfhydrate on sodium chloroacetate and by electrolysis of dithioglycollic acid from sodium sulfide and sodium chloroacetate. It's also fashioned by heating chloroacetic acid with potassium hydrogen sulfide. Thioglycolic acid and its salts and glyceryl esters are usually not regarded to occur By natural means.
