Ammonium thioglycolate (NH₄⁺ HSCH₂COO^-) is listed as the reducing agent on a lot of hair "perming" kits.  It reduces the disulfide bonds in the hair to thiol groups.  However, what is the oxidized form of this compound?  Is a C=S bond formed (making the oxidized compound like a sulfur analog of an aldehyde)?  I don't see any other place on the molecule that oxidation could occur, but the resulting compound in that case seems weird to me.  Thanks for any input you can offer.
