Monoethanolamine Thioglycolate

(Monoethanolamine mercaptoacetate) CAS# 126-97-6, EC# 204-815-4

Structure

Dr. Ralph Evans developed in Hoboken, New Jersey, in the early 1940s Thioglycolic Acid as an active material for cold wave permanents. Today mainly TGA salts are used in cosmetic applications for hair perms, straighteners and depilatories.

Ammonium Thioglycolate or Monoethanolamine Thioglycolate are used in cosmetics for hair perms and straigtheners whereas Calcium Thioglycolate and Potassium Thioglycolate are used in depilatories.

Properties

Monoethanolamine Thioglycolate's unique reducing properties of the SH-group opens the sulfur bridges in the ceratine structure of the hair. If this is done when the hair is wrapped around hair rollers, the hair structure is weakened. After rinsing in a second step the sulfur bridges are reconnected with an oxidizing chemical like hydrogenperoxide and the hair fibre gets its desired curled shape. These properties allow the use in hair perms as well as in hair straighteners. In the latter case the pH-value of the formulations is higher.

If the ammonia smell of a formulation with high pH-value containing Ammonium Thioglycolate (like in hair straighteners) is not desirable then the use of the nearly odorless Monoethanolamine Thioglycolate instead of Ammonium Thioglycolate is advantageous.
