Thioglycolic Acid & Derivative

Thioglycolic acid is used in Construction chemical as transferring agent , cosmetic formulations including permanent wave solutions and depilatories, in pharmaceutical manufacture, and as a stabilizer for vinyl plastics. TGA is often called mercaptoacetic acid (MAA). It contains both a thiol (mercaptan) and carboxylic acid functional groups. It is a colorless liquid with a strongly unpleasant odor. TGA is miscible with polar organic solvents. It is an alternative to 3MPA – 3 mercaptopropionic-acid, a strong reducing agent especially at high pH and a good nucleophilic agent.
