hair remover
If you are making a facial hair remover how much Potassium Thioglycolate should you use. How much should you use for a body remover?

personally, if I were creating a body remover, I’d use something like concentrated nitric acid, but if the police ask you any questions I said nothing
facetious remarks aside, it depends on the legal limits in the area you intend to sell it; in Europe, for instance, the maximum thioglycolate level for depilatories is 5% as thioglycolic acid (hence, the limit for potassium thioglycolate is 5% × 130 g/mol ÷ 92 g/mol = 7.06%), and the pH of the product must be between between 7.0 and 12.7

Thanks @Bill_Toge.
Its planning to be sold in China. Can you explain the equation you did. I know 130g is the MW of K-Thio.g what is 92 g/mol. -

@Chemist5000 thioglycolic acid has a molecular weight of 92 g/mol
the European legal limit is stated as %w/w thioglycolic acid; the conversion factor (130 g/mol ÷ 92 g/mol) accounts for the difference in molecular weight between the acid and its potassium salt
