A specialty fragrance aldehyde — used sparingly; like other aldehydes it carries some sensitization potential.
Decyloxyacetaldehyde is a synthetic fragrance aldehyde (an ether-aldehyde C12 molecule) used as a fragrance/odour component in perfumes. Aldehydes as a class contribute to 'sparkly', aldehydic and marine/fresh olfactory profiles and are controlled under IFRA/RIFM guidance, which sets maximum use levels based on product type to manage dermal sensitization risk. Independent safety data for this specific compound are limited; it should be used within IFRA category limits and is best considered one of many fragrance components rather than a leave-on active.
