In short
beta-Caryophyllene is a sesquiterpene found in clove, black pepper, copaiba and hops. It has a dry, woody-spicy odour and is a common blender in spicy and woody accords.
What beta-Caryophyllene smells like
beta-Caryophyllene is woody-spicy, dry and tenacious, in Takasago's listing; other suppliers add a clove note — sweet, woody-spice, clove, dry and tenacious. It is a major constituent of clove, black pepper and copaiba, and gives black pepper oil its warm, woody base.

What makes beta-Caryophyllene distinctive
The dry woody-clove backbone of pepper, clove and copaiba, as a single molecule.
How beta-Caryophyllene is used
Used as a dry, woody-spicy modifier in woody, spicy and oriental compositions.
Typical role: modifier (used in small amounts to change the character of a blend); blender (smooths the joins between other materials).
How beta-Caryophyllene differs from similar materials
- Caryophyllene Oxide
- The oxide is woodier and more ambery, slightly camphoraceous; the hydrocarbon is the drier, clove-like spice.
- Copaiba Balsam
- Copaiba is largely caryophyllene, adding a balsamic, creamy softness. (compared directly by a cited source)
- Sabinene
- Sabinene is fresher, more peppery and short-lived; caryophyllene is dry, woody and clove-like, and lasts.
- alpha-Humulene
- alpha-Humulene, its close relative, is more resinous and bitter; caryophyllene is drier and more clove-like.
An asterisk marks a difference that a cited source states directly. The others compare the published descriptions of each material. Smell varies with grade, supplier and dilution; compare them side by side on blotters before substituting one for another.
Formulation considerations
Oxidises to caryophyllene oxide, which is a known sensitiser; store well closed.

Safety and compliance
Hazard classification of the neat substance, as PubChem summarises it, read 26 October 2026. Companies notifying the ECHA C&L Inventory classify it (2,064 reports): H304 may be fatal if swallowed and enters airways (99.5% of reports); H317 may cause an allergic skin reaction (78.9% of reports). 2 of the reports find it does not meet the hazard criteria. A skin sensitiser classification concerns handling the neat material and the dose in a finished product; the IFRA Standards, where they apply, set the limits. Unless it is harmonised, this is the notifiers' own classification, not a binding one.
This page is general information, not a safety assessment or a specification. Confirm identity, composition, IFRA status and allergen content from your supplier's documents for the lot you hold.
