Thioglycolic Acid, with the CAS number 68 - 11 - 1, is an important organic compound. It is a colorless to slightly yellowish liquid with a pungent odor. The chemical formula of Thioglycolic Acid is C2H4O2S. Its molecular weight is approximately 92.11 g/mol.
This product is soluble in water, ethanol, and ether. It has a boiling point of around 123 - 125°C at 15 mmHg and a melting point of - 16.5°C. The density of Thioglycolic Acid is about 1.325 g/mL at 25°C. It is a strong reducing agent and is sensitive to air and light.
Thioglycolic Acid has a wide range of applications in various industries:
When using Thioglycolic Acid, strict safety precautions should be followed:
Case 1: Hair - perming in the Beauty Salon
In a beauty salon, a professional hairstylist uses a hair - perming solution containing Thioglycolic Acid. First, the hairstylist carefully applies the solution to the client's hair, making sure it is evenly distributed. The Thioglycolic Acid in the solution breaks the disulfide bonds in the hair, allowing the hair to be wrapped around perm rods to achieve the desired curl shape. After a specific time, a neutralizer is applied to reform the disulfide bonds, fixing the curl. The result is a long - lasting and natural - looking curly hair style.
Case 2: Metal Surface Treatment in a Manufacturing Plant
A manufacturing plant produces metal parts that require a high - quality surface finish. The workers use a solution of Thioglycolic Acid to remove the oxide layer on the metal surface. They immerse the metal parts in the solution for a certain period, during which the Thioglycolic Acid reacts with the metal oxides. After the treatment, the metal surface becomes clean and smooth, which improves the adhesion of the subsequent paint coating. This leads to a more durable and aesthetically pleasing metal product.
