About

A fragrance acetal derived from benzaldehyde and glycerin, used as a fixative and aromatic material in perfumery. The parent compound benzaldehyde is listed as a fragrance allergen requiring declaration.

This cyclic acetal is produced by acid-catalyzed condensation of benzaldehyde with glycerin, functioning as a fragrance ingredient with slow release characteristics. Benzaldehyde, its metabolic precursor, is listed in EU Cosmetics Regulation Annex III (part 1) as a fragrance allergen requiring mandatory declaration in the ingredient list when present above 0.001% in leave-on or 0.01% in rinse-off products. The acetal form may hydrolyze partially to release benzaldehyde, contributing to overall allergen exposure.

Known concerns

  • Benzaldehyde is an EU-declared fragrance allergen
  • Potential for hydrolysis releasing benzaldehyde
  • Environmental hazard (aquatic toxicity) noted in PubChem score of 55
