What is Sodium thioglycolate?
Sodium thioglycolate (CAS 367-51-1), abbreviated NATG, is the sodium salt form of thioglycolic acid.
Where is Sodium thioglycolate used?
- Personal care: reducing agent and depilatory active that breaks disulfide bonds in keratin, as in depilatory creams and cold wave permanent solutions
- Leather processing: unhairing of hides without mechanical damage
- Textile production: wool treatment to reduce fiber stiffness and improve dye uptake
- In analytical and industrial chemistry it acts as a stabilizing agent and metal chelator.
Commercial specifications
- Aqueous solution, 40% to 58% concentration
- Technical and cosmetic grades; cosmetic grade subject to purity thresholds aligned with regional regulatory requirements
- Bulk liquid in drums or IBCs
