What is Glyceryl monothioglycolate CAS 30618-84-9？

Glyceryl monothioglycolate is a transparent oily liquid. The boiling point is 244 ℃ [at 101 325 Pa], the density is 1.315 [at 20 ℃], and the vapor pressure is 0.001Pa at 25 ℃.

Glyceryl monothioglycolate (CAS 30618-84-9) is an ester of thioglycolic acid and glycerin. It is best known as a key ingredient in hair perming formulations due to its ability to break and reform disulfide bonds in hair keratin, allowing for effective and long-lasting curls or waves.

With excellent reducing properties, this compound is widely used in the cosmetic and personal care industry as a hair waving and relaxing agent. It is often considered a safer alternative to ammonium thioglycolate, offering milder action and improved hair feel after treatment.
