In short
Buccoxime is a trade name for a bicyclic oxime with a blackcurrant and buchu-leaf odour. It gives cassis effects without the sulfur materials usually needed for them.
What Buccoxime smells like
Buccoxime (Symrise) has a fresh, fruity and herbal odour with a bucco (buchu) leaf oil character, per Symrise's listing; a distributor's description of the 10% product gives a fresh aroma with blackcurrant and buchu-leaf notes. Buchu itself is commonly described as blackcurrant-bud, minty, camphoraceous and sulphurous. Few detailed descriptions exist. The Good Scents Company's own evaluation, at 1% in dipropylene glycol, is clean, fresh, fruity and natural buchu leaf, of high strength.

What makes Buccoxime distinctive
A blackcurrant-buchu note without the sulphur of the mercaptans — fresher and more herbal.
How Buccoxime is used
Used for blackcurrant and buchu effects in fruity and green compositions.
Typical role: modifier (used in small amounts to change the character of a blend).
How Buccoxime differs from similar materials
- 8-Mercapto-p-menthan-3-one
- Mercaptomenthone is the sulphurous buchu-blackcurrant thiol — powerful and catty; Buccoxime is a fresher, herbal, non-sulphur oxime.
- Blackcurrant Bud Absolute
- The absolute is the natural blackcurrant bud, green and catty-sulphurous; Buccoxime is a cleaner, herbal buchu-blackcurrant.
Each difference compares the published descriptions of the two materials. Smell varies with grade, supplier and dilution; compare them side by side on blotters before substituting one for another.
