Diammonium dithioglycolate

Diammonium dithioglycolate (CAS 68223-93-8, EC 269-323-4), also referred to as DADTG, ammonium dithiodiglycolate, or diammonium dithiodiacetate, is the diammonium salt of dithiodiglycolic acid. It carries no assigned E-code and is distinct from the monoammonium form used in some cosmetic applications.

In permanent waving and hair relaxer formulations, it functions as a reducing agent by cleaving disulfide bonds in keratin, enabling controlled restructuring of the hair fiber. In textile and leather processing, it acts as a reducing and complexing agent, facilitating fiber preparation and assisting in metal ion control during dyeing and tanning operations.

The compound is supplied under REACH registration requirements applicable to EU markets and is available in aqueous solution form, with concentration and packaging formats confirmed at the point of inquiry. Buyers should request a full safety data sheet and certificate of analysis to verify grade suitability for their specific process.
