About
TETRAHYDRO-DIMETHYLNAPHTHYL-PROPAN-1-ONE is a cosmetic ingredient used in product formulation. Exercise caution due to limited available safety data.
Tetrahydro-Dimethylnaphthyl-Propan-1-one is a tetralin (tetrahydronaphthalene) ketone with a propanone substituent. The saturated bicyclic ring system provides metabolic stability compared to unsaturated aromatic analogs. It is not listed in EU Annex II (banned substances) or Annex III (restricted substances) of the Cosmetics Regulation, suggesting permitted cosmetic use. The ketone functionality is adjacent to the tetralin ring (position 1), which may contribute to some reactivity, but the saturated nature of the ring system limits oxidative metabolism concerns.
Skin benefits
- Provides amber, woody, tobacco-like fragrance notes

Known concerns
