Product Description

As a notable firm, we are offering a unique stock of Thio Glycolic Acid. It ensures a high-performance chemical containing mercaptan and carboxylic acid functionalities. Apart from this, provided acid is completely miscible in water. It is used in the gas, cosmetics, cleaning, polymerization etc. Thio Glycolic Acid forms powerful complexes with metals. It is highly effective for cleaning and corrosion inhibition. It is more efficient than classic ferric reducing agents. It controls a very high concentration of ferric iron.


Thioglycolic acid (TGA or mercaptoacetic acid, CAS 68-11-1) is a high-performance chemical containing mercaptan and carboxylic acid functionalities. TGA is completely miscible in water and is used in industries and applications as diverse as oil and gas, cosmetics, cleaning, leather processing, metals, fine chemistry and polymerization. Thioglycolic acid forms powerful complexes with metals that give it specific characteristics sought after for the assisted recovery of ore as well as for cleaning and corrosion inhibition and hair removal creams in cosmetics.

KEY BENEFITS OF TGA At temperatures above 70°C – common temperatures in well bores – TGA is more efficient than classic ferric ion chelating agents (citric acid, acetic acid, EDTA, NTA). Moreover, TGA is more efficient than classic ferric reducing agents, such as erythorbic acid or ascorbic acid.


  • TGA reduces Fe3+ (ferric) ions to chelated Fe2+ (ferrous) ions that remain in solution at pH < 7.5
  • TGA is stable and efficient at low pH (TGA rapidly reduces high quantities of Fe3+)
  •  TGA can control very high concentrations of ferric iron – up to about 10%.





Due to its mercaptan functional group, thioglycolic acid and its salts provide essential properties in a wide range of applications:

·        Polymerization: TGA is a very effective chain transfer agent for emulsion polymerizations in aqueous media, in particular for acrylic acid and acrylates. The total miscibility of TGA with water is a benefit in this application.

·        Petrochemical: The Bronsted acid characteristics of thioglycolic acid and its thiol functionality make it a chemical of choice for the preparation or regeneration of metal catalysts for hydrodesulfurization.

·        Cosmetics: The salts of thioglycolic acid are used to formulate hair treatments, specialty hair styling products, and in the preparation of depilatory creams. The main salts are ammonium, calcium and potassium thioglycolate or its disulfide salts. In some formulations, glyceryl monothioglycolate is also used.

·        Leather Processing: Alkaline sodium thioglycolate is used in removal of hair from leather hides. It minimizes wastewater treatment costs as compared to the more toxic and harmful sodium hydrosulfide
