About
A diene carboxylate ester used as a fragrance ingredient with structural alerts for photosensitization but no current EU restrictions.
Ethyl 2,6,6-trimethylcyclohexa-2,4-dienecarboxylate is a cyclohexadiene derivative used in fragrance compounds. The conjugated diene system raises photosensitization potential similar to alpha-terpinene-type structures. No H statements are listed, indicating low acute toxicity. EU SCCS review of diene carboxylate esters notes limited dermal absorption but flags them for phototoxicity screening. Not currently on EU Annex II (banned) or Annex III (restricted) lists, though IFRA recommendations apply for certain diene-containing fragrance chemicals.
Known concerns
- Conjugated diene structure may cause photosensitivity in sunlight-exposed skin
- Limited long-term safety and sensitization data
- EU IFRA recommendation flags certain diene fragrance materials
