About

An aldehyde derivative modified with a hexenyloxy group that provides a complex green-floral scent profile. The combination of aldehyde and ether structures elevates its sensitisation potential compared to simple aldehydes.

This compound is a hybrid aldehyde-ether structure featuring a cis-3-hexenyloxy substituent attached to an acetaldehyde moiety. Used as a fragrance ingredient to convey green, slightly floral top notes, it has been reviewed by IFRA due to the presence of both an aldehyde group (a known alert for sensitization) and an ether linkage (which can affect skin penetration). Not listed on EU cosmetic annexes, but IFRA standards apply.

Skin benefits

  • Fragrance material; no direct skin conditioning benefits

Known concerns

  • Skin sensitizer potential due to aldehyde moiety
  • IFRA recommended restrictions apply
  • Limited long-term toxicological data
