Safety Profile
GENERALLY SAFEWhat Does Cassis bud absolute Smell Like?
Cassis bud absolute bursts with an intensely green, sappy opening – like crushing fresh blackcurrant leaves between your fingers. The tartness evolves into a jammy fruitiness reminiscent of ripe blackcurrants, with a subtle musky-animalic undertone that adds depth. As it dries down, a delicate floralcy emerges, like the first blossoms of spring, resting on a soft woody-mossy base that lingers for hours.

Chemistry, Properties & Perfumer Guide
The Chemistry
Cassis bud absolute is obtained through solvent extraction of Ribes nigrum buds, yielding a complex mixture of terpenes, esters, and sulfur compounds. Key constituents include β-damascenone for fruity notes, (Z)-3-hexenol for green freshness, and trace sulfur compounds contributing to the characteristic cassis aroma. The extraction process carefully preserves these volatile top notes while concentrating the heavier musky components.
