Description and usage notes: A brilliant ingredient for many floral blends that helps to bring out the floral and fruity aspects of other materials. Description from Givaudan: "Undecavertol was developed in connection with structural elucidation work on unknown trace components of lily-of-the-valley. It has a powerful green-floral character, somewhat related to lily-of-the-valley, with natural, fresh, fruity violet leaf and linden-blossom aspects. It can be used successfully in rose and fruity pear accords. Although easy to use in most perfumery types, Undecavertol requires careful dosage and blending due to its exceptional strength.” According to Scent and Chemistry, "Violettyne (undeca-l,3-dien-5-yne), Neofolione (methyl non-2-enoate), or Undecavertol (4-methyldec-3-en- 5-ol)" are the main materials used to replicate the effect of methyl heptyne carboxylate, most notoriously associated with Jean-Louis Sieuzac's Fahrenheit (Dior, 1988). Jean Claude Elena, in his book Diary of a Nose, suggests that in combination with Lilial this material can produce an effective illusion of the smell of lime blossoms (also known as linden blossom). He says “I have never succeeded in using this tree’s blossom to my advantage.  All I can do is fall asleep in its dark shade”.  While Elena was sleeping however the Pell Wall perfumer has incorporated a complex linden blossom accord into the fragrance Beaver, by Zoologist Perfumes.
