Description and usage notes:
A higher impact version of Hedione, particularly useful in masculine fragrances, but can also be used in all the ways regular Hedione is used but giving a fresher, more petal-like impression. Often preferred in fine fragrance applications, its use in functional products is diminished by its tendency to deteriorate into regular Hedione in acidic or alkaline media.
Description from Firmenich: ”A unique powerful, floral note reminiscent of magnolia blossoms. Use: HEDIONE® HC has wonderful booster effects. It has a strength far superior to that of the classical Hedione® due to its high cis concentration.”
Note that this version (from Firmenich) contains about 75% of the desirable Cis isomer – higher than most competing products.
