About
A saturated bicyclic aldehyde fragrance ingredient that contributes warm, woody notes to perfumes, with no current EU restrictions at the time of evaluation.
Octahydro-5,5-dimethylnaphthalene-2-carbaldehyde is a saturated tricyclic aldehyde (a derivative of tetrahydronaphthalene) used as a fragrance ingredient. It is not listed in EU cosmetic regulation Annexes, but as an aldehyde it may cause skin sensitization in susceptible individuals. Fragrance industry data suggests safe use levels, and it is evaluated by IFRA as a fragrance material. Aldehydes in this class are typically restricted by IFRA guidelines rather than EU regulation.
Known concerns
- Potential aldehyde-type skin sensitization
- Fragrance allergen consideration
