Regulatory evidence across markets

None of the 13 markets tracked here holds an imported rule under the name SODIUM NAPHTHALENESULFONATE.

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.

Sodium 1-naphthalenesulfonate

On the basis of the available data, the CIR Panel concludes that Sodium Polynaphthalenesulfonate and Sodium Naphthalenesulfonate are safe as used in cosmetic formulations intended to be applied to the skin. The available data, however, are insufficient to support the safety for use in cosmetic products which may contact mucous membranes or be ingested. — Cosmetic Ingredient Review (CIR)
