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.
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.
