Aldehyde C-11 Undecylenic
Fresh Aldehydic
Aldehyde C-11 Undecylenic is valued by perfumers for its ability to add brightness, freshness, and lift to fragrance compositions. It imparts elegant green, waxy, rosy, and slightly citrusy nuances, enhancing floral, woody, chypre, marine, and clean-fresh accords.
