Monoethanolamine thioglycolate

Monoethanolamine thioglycolate (CAS 126-97-6), also known as ethanolamine thioglycolate, is a salt formed from monoethanolamine and thioglycolic acid; a reducing agent in hair treatment formulations.

Where is Monoethanolamine thioglycolate used?

• Hair treatment: breaks disulfide bonds in keratin, enabling permanent restructuring of hair fiber
• Permanent wave solutions: active ingredient that softens and reshapes the hair's internal protein structure
• Depilatory creams: degrades disulfide linkages in hair at the skin surface for chemical hair removal
• Straightening and relaxing formulations for coarse or curly hair: alternative to lye-based systems
• Hair bond-breaking pre-treatments ahead of color or bleach services reduce mechanical damage
• Before neutralization fixes the new curl pattern, the chemical modifies the protein bonds.

Good to know: Milder chemical agents are preferred for sensitive scalp conditions. Buyers should confirm concentration and purity certificates when sourcing for regulated personal care markets.
