Aldehyde C-11 Undecylenic
Description
Powerful, mildly waxy, rosy-citrusy odor of moderate to good tenacity. The material polymerizes in air, and forms adduct with Amines (Indole, Anthranilates, Quinolines, etc.). It is one of the most frequently used of all the alifatic aldehydes, although the concentration in perfume oils is normally as low as 0.1 to 0.5 %. Its unusual diffusive power, the lift and radiation it can introduce in a fragrance, are highly appreciated effects even in soap perfumes.
