Ammonium thiolactate

Ammonium thiolactate (CAS 13419-67-5) is the ammonium salt of thiolactic acid; a reducing and buffering agent for personal care, textile and pharmaceutical manufacturing.

Where is Ammonium thiolactate used?

• Hair care: active reducing agent in permanent wave and chemical straightening formulations, softening keratin bonds for controlled reshaping
• Leather processing: assists depilation and fiber relaxation during hide preparation, reducing reliance on aggressive sulfide chemistries
• Textile processing: applied in wool treatment to improve fiber receptivity before dyeing or finishing
• Pharmaceutical and cosmetic formulations: pH buffer and mild antioxidant stabilizer in formulations sensitive to oxidative degradation
• Its thiol-reactive chemistry breaks and reforms disulfide bonds in protein-based substrates.

Good to know: Buyers should confirm active content and pH specification with suppliers, as these parameters affect performance.

Commercial specifications

• Concentration ranges vary by application grade
