Sodium thioglycolate can be a white powder that has a melting point increased than 300°C. It appears as hygroscopic crystals using an unpleasant odor characteristic from the sulfhydryl group (mercaptans). Thioglycolic acid is often geared up because of the motion of sodium sulfhydrate on sodium chloroacetate and by electrolysis of dithioglycollic acid from sodium sulfide and sodium chloroacetate. It's also formed by heating chloroacetic acid with potassium hydrogen sulfide. Thioglycolic acid and its salts and glyceryl esters aren't recognised to arise By natural means. Sodium thioglycolate is used in the cosmetic industry as an antioxidant, depilating agent, hair waving/straightening agent, and cutting down agent. Its Key cosmetic use is in depilatories.

They can be found evenly distribute throughout the test tube. Thioglycolate broth can be a multipurpose, enrichment, differential medium used generally to ascertain the oxygen necessities of microorganisms. Sodium thioglycolate while in the medium consumes oxygen and permits The expansion of obligate anaerobes.[one] This, combined with the diffusion of oxygen through the prime in the broth, creates A selection of oxygen concentrations within the medium along its depth. The oxygen concentration in a provided stage is indicated by a redox-sensitive dye such as resazurine that turns pink inside the presence of oxygen.
