About

A saturated bicyclic aldehyde fragrance with environmental toxicity concerns, showing no evidence of skin sensitization at typical use levels.

Octahydro-8,8-dimethyl-2-naphthaldehyde is a saturated bicyclic aldehyde fragrance material classified as H412 (harmful to aquatic life with long-lasting effects). This environmental classification is the primary concern, as cosmetic products inevitably enter waterways through wash-off. It is not listed in EU Annex III restrictions but should be used within IFRA guidelines. The ingredient lacks classified skin sensitization potential under CLP.

Known concerns

  • Aquatic chronic toxicity (H412)
  • Environmental concern in wash-off products
