Chemical identity and properties
Monoethanolamine thioglycolate
Based on the available data, the CIR Expert Panel concluded that ... Ethanolamine Thioglycolate is safe for use in hair straighteners, permanent waves, tonics, dressings, and so forth, wave sets, other non-coloring hair products, and hair dyes and colors, as described in this safety assessment, at concentrations up to 15.2% (as Thioglycolic Acid). Hairdressers should avoid skin contact and minimize consumer skin exposure. — Cosmetic Ingredient Review (CIR)
