Sodium thioglycolate can be a white powder using a melting point increased than three hundred°C. It seems as hygroscopic crystals with the disagreeable odor characteristic of the sulfhydryl team (mercaptans). Thioglycolic acid might be well prepared by the action of sodium sulfhydrate on sodium chloroacetate and by electrolysis of dithioglycollic acid from sodium sulfide and sodium chloroacetate. It is also fashioned by heating chloroacetic acid with potassium ammonium bisulphite solution hydrogen sulfide. Thioglycolic acid and its salts and glyceryl esters aren't recognized to take place Normally.
