Unpleasant Odour

Mercaptoacetic acid, with the formula HSCH2COOH, can also be called thioglycolic acid or sulfanylacetic acid. Think of it as a methylene group (-CH2-) “sandwiched” between a thiol (also known as a mercaptan group, -SH) and a carboxylic acid (-COOH).

It’s a colourless liquid, with a strong unpleasant odour characteristic of sulphydryl groups. It’s miscible with many different solvents, including water, alcohol and ketones. Full safety measures are available online to download. Operators must wear protective clothing, as it may cause burns and may be toxic if inhaled.

Cosmetic Applications

This compound was originally synthesised in the 40s and it’s still in use today, mainly in the cosmetic industry. It was initially used in chemical depilation, especially in salt forms mixed with calcium (HSCH2COOCa) and sodium (HSCH2COONa).

Nowadays, mercaptoacetic acid is mainly used mixed with ammonium to form HSCH2CO2NH4, which has become known amongst hairdressers as “perm salt.”

When this solution is applied to hair, the ammonia renders the hair fibres permeable to the mercaptoacetic acid, which then breaks the disulphide bonds. The hair is then treated with hydrogen peroxide to make the “curls” permanent.

Other Applications

This chemical can be used for many other applications:

  • Leather processing
  • Acidity indicator
  • Detection of iron, silver, tin and molybdenum
