About
An unsaturated nine-carbon aldehyde delivering powerful green, melon-like aromatic notes. Like other non-enals, it is considered a potential skin irritant and sensitizer, limiting its use to trace fragrance levels.
Cis-6-non-6-enal is an isomer of nonenal, a class of compounds known for their intense green-floral odors found in cucumber, watermelon, and rose. The non-enals are recognized as potent odorants but also as skin irritants and potential sensitizers in the IFRA fragrance allergen framework. EU cosmetic regulations may require allergen labeling if the compound falls under the fragrance allergen declaration rules, though specific non-enal listings are considered on a case-by-case basis by suppliers.
