alpha-hexylcinnamic aldehyde Description and usage notes: One of the essential components of almost every jasmine recreation, this is a lovely soft floral material with only a slight spice note. Longer lasting than the similar Amyl Cinnamaldehyde. According to Arctander it is: “Very mild, sweet-oily, slightly floral odor with a trace of herbaceous undertones. The odor becomes considerably more floral and lively when the material is incorporated with more volatile material in a composition... This aldehyde finds considerable use in perfume formulations for its rich floral and pleasant oily-herbaccous odor-contribution to Jasmin bases, Gardenia, Tuberose, Magnolia, etc. and in general as part of a floral theme in other fragrance types.”  Hexyl cinnamaldehyde can oxidise easily, resulting in unpleasant cardboard-like off-odours.  To minimise this we have chosen to stock material pre-stabilised with BHT by the manufacturer and we keep our stocks in cold storage to maintain maximum freshness: we recommend you do the same.
