Diammonium dithiodiglycolate

Diammonium dithiodiglycolate (CAS 68223-93-8 ), also referenced as diammonium 2,2'-dithiodiacetate, is an ammonium salt of dithiodiglycolic acid used across textile, leather, and personal care processing.

It functions primarily as a reducing and complexing agent where controlled disulfide bond chemistry is required. In hair care formulations, it acts on keratin disulfide bonds to enable permanent waving treatments.

This chemical serves as an alternative to thioglycolate-based systems for relaxing and straightening. Textile processors use it in wool and fiber treatment baths where selective reduction of disulfide linkages is needed.

This process allows for the modification of fiber structure before dyeing or setting. In leather processing, it supports depilation and hide preparation steps that require controlled sulfur chemistry.

It provides these benefits without the harsh odor profile of conventional sulfide systems. Paper and pulp applications leverage its complexing behavior to manage metal ion interference during bleaching sequences.

The product is supplied as an aqueous solution, with concentration levels varying by application requirement. It is available in technical and cosmetic grades to meet specific industry needs.

Cosmetic-grade material meets the purity standards expected for leave-on and rinse-off personal care formulations. Bulk supply is typically offered in intermediate bulk containers or drums.

These packaging options are suited to industrial processing volumes. The material should be handled according to standard safety protocols for ammonium salts and sulfur-based reducing agents.
