Myristaldehyde — a C14 fatty aldehyde giving creamy, soapy perfumery notes; used under normal IFRA controls.
Myristaldehyde (tetradecanal, CAS 124-25-4) is a C14 saturated fatty aldehyde widely used as a fragrance ingredient contributing waxy, soapy, creamy notes characteristic of 'aldehydic' perfume compositions. Straight-chain aliphatic aldehydes are regulated by IFRA with maximum-use levels based on RIFM sensitization data; they can oxidize over time to the corresponding acid. Generally well tolerated within fragrance-use limits; like other aldehydes it contributes to fragrance-allergy risk in susceptible users.
