Regulatory evidence across markets

None of the 13 markets tracked here holds an imported rule under the name GLYCERYL THIOGLYCOLATE.

That is a statement about this inventory, not about the law: no imported rule is not evidence that a substance is permitted. A rule may exist under a different name, under a CAS or EC number this glossary entry does not carry, or in a dataset not yet imported.

Glyceryl monothioglycolate

Glyceryl monothioglycolate is a thioglycolate ester resulting from esterification of thioglycolic acid with glycerol. As a component of developer solutions in permanent wave products, it is the second most frequent allergen in hairdressers and avoidance of acid permanent waves is mandatory. It has a role as an allergen. — ChEBI
