About

Diamylhydroquinone is a cosmetic ingredient used in product formulations. Exercise caution due to limited available safety data.

Diamylhydroquinone is a substituted hydroquinone (dihydroxybenzene) derivative used as an antioxidant in cosmetic formulations. While not listed in EU Annex II (banned substances), hydroquinone derivatives have raised regulatory concern due to potential ochronosis with prolonged use and skin sensitization. EU safety assessment would require extensive data before permitting use at meaningful concentrations.
