About
An aromatic aldehyde with a tetrahydronaphthalene ring structure, used as a fragrance component. The aldehyde functional group presents some sensitization potential.
Tetrahydronaphthalene-1-Acetaldehyde is a partially saturated bicyclic aldehyde fragrance ingredient. The tetralin (tetrahydronaphthalene) skeleton is structurally similar to some allergenic fragrance materials. It is not listed in EU Annex II or III of the Cosmetics Regulation, indicating permitted cosmetic use. However, the aldehyde group may contribute to skin sensitization, particularly in leave-on products, and should be used at controlled concentrations.
