Ethyl Vanillin is a very powerful perfumery material, more so than Vanillin and is best used in dilution. Very sweet with caramel undertones. It can be used in traces to sweeten florals and add creamy effects, especially to the yellow varieties. Or can be overdosed to create sweet gourmand formulas. A highly impactful powerful fixative base that lasts 400 hrs on a scent strip.

“This aldehyde is widely used in perfumery as a sweetener and fixative, not only in very sweet type floral fragrances and the conventional fruity lipstick-type fragrances, but in general as part of the fixative element in perfume compositions where a creamy sweetness is desirable, particularly in combination with florals such as Ylang-Ylang, or with all members of the Eugenol family in Carnations, etc.
Ethyl vanillin is often used to substitute a larger amount of Vanillin in a fragrance when a discoloration problem arises, due to the active hydroxyl- or aldehyde-groups of the Vanillin/Ethylvanillin molecules. The discoloration hazard can be reduced and the sweetness maintained although there will be a loss in physical fixation effect.”
