This plot, which can be frequently smoothed, is referred to as a TGA curve. The 1st by-product with the TGA curve (the DTG curve) might be plotted to find out inflection details handy for in-depth interpretations as well as differential thermal Assessment.

TGA was made in the 1940s to be used to be a chemical depilatory and remains utilized as a result, specifically in salt varieties, together with calcium thioglycolate and sodium thioglycolate. TGA will be the precursor to ammonium thioglycolate that is certainly employed for permanents. TGA and its derivatives split the disulfide bonds during the cortex of hair.

Thioglycolic acid is a delicate reagent to the resolve of iron, molybdenum, aluminum, tin, etc., and it is an inhibitor of copper sulfide and iron sulfide minerals in beneficiation. During the petrochemical field and also the railway sector, it really is employed for cleansing and derusting of kit and rails. It can be used as being a crystallization nucleating agent in polypropylene processing and molding, for a modifier for coatings and fibers, being a blanket quickening agent, to be a stabilizer raw materials for polyvinyl chloride and rubber, as a cold perm agent, and as a pharmaceutical intermediate.
Thioglycolic acid is utilised as nucleophile in thioglycolysis reactions used on condensed tannins to study their composition.
