TGA is used to be a chemical depilatory and remains to be used as such, particularly in salt types, including calcium thioglycolate and sodium thioglycolate. TGA may be the precursor to ammonium thioglycolate, which happens to be used for permanents. TGA and its derivatives break the disulfide bonds within the cortex of hair.
The output and use of sodium thioglycolate is associated with the output and usage of thioglycolic acid. Thioglycolic acid may be prepared by the motion of sodium sulfhydrate on sodium chloroacetate and by electrolysis of dithioglycollic acid from sodium sulfide and sodium chloroacetate.
