Does Nair contain Mercury?

Nair Hair Remover Cream contains Potassium thioglycolate (article ). I've read articles that said anything with a "mer-" or "thio-" at the front of the name is derived from mercury. More to the point, the chemical potassium thioglycolate has a fact sheet here: which says it's also known as anything "mercapto-," such as Mercaptoacetic acid, and Potassium mercaptoacetate. So while I can't find anything specifically saying that these are all mercurials...wouldn't this make sense?

Organic chemicals with "thio" or "mercapto" in the name contains a thiol group -- HS -- , not Mercury.

No Mercury (Hg) in there!

The name mer- at the front of the name does not derive by mercury but by mercaptan.

Thiols are also referred to as mercaptans . They are compounds that contains the functional group - SH.

Mercapto- and thio- refers to the R-SH and the R-S-R' functional groups respectively. They have nothing to do with the heavy metal Hg.
