Flash point data for Sodium thioglycolate are not available. Sodium thioglycolate is probably combustible.
It crystallises from 60% EtOH (charcoal). It is hygroscopic.[Beilstein 3 IV 600.]
Air & Water Reactions
Hygroscopic. Discolors on exposure to air. Water soluble.
White powder with a slight odor. Used in cold-waving of hair and as a dipilatory.
dipilatory, irritant, chelating agent
Sodium thioglycolate is hygroscopic and sensitive to air. Discolors if exposed to iron . May generate flammable and toxic hydrogen sulfide with strong reducing agents.
In cold-waving of hair; as depilatory; in bacteriology for the preparation of thioglycolate media; as analytical reagent, see Thioglycolic Acid.
