In short
Camphene is a bicyclic monoterpene found in conifer, rosemary and citronella oils. It has a camphoraceous, piney odour.
What Camphene smells like
Camphene is a waxy white solid that melts at about 50 °C. The Good Scents Company's own panel describes it as camphoraceous, cooling and piney-woody with terpy nuances, and with citrus, green-minty and green-spicy notes; Takasago gives oily-camphoraceous for its grade, which it says is widely used in pine, lavender and citrus fragrances, and Moellhausen harsh, camphoraceous and coniferous. It is a constituent of many conifer oils, notably Siberian fir and black spruce.

What makes Camphene distinctive
An oily, cooling camphor note with a piney-woody body: more camphoraceous than the pinenes, and harsher and oilier than their clean green pine.
How Camphene is used
Used in conifer reconstructions and fresh compositions, and as an intermediate for other aroma chemicals.
Typical role: modifier (used in small amounts to change the character of a blend).
How Camphene differs from similar materials
- beta-Pinene
- beta-Pinene is the drier, woodier green-pine note; camphene is oilier and more camphoraceous, with a cooling edge.
- Siberian Fir Needle Oil
- Siberian fir contains a large share of camphene beside bornyl acetate and alpha-pinene. (compared directly by a cited source)
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
A waxy solid; dissolve before use.

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 (2,128 reports): H410 very toxic to aquatic life with long lasting effects (97.6% of reports); H319 causes serious eye irritation (97.5% of reports); H228 flammable solid (94.8% of reports); H400 very toxic to aquatic life (85.8% of reports); H304 may be fatal if swallowed and enters airways (61.4% of reports). 48 of the reports find it does not meet the hazard criteria. Unless it is harmonised, this is the notifiers' own classification, not a binding one.
