What Is Camphene? Aroma, Uses and Camphor Differences

What is camphene?

Camphene belongs to the monoterpene family. “Mono” refers to a terpene built from two five-carbon units, giving the molecule 10 carbon atoms. “Bicyclic” describes its two-ring structure.

The NIST Chemistry WebBook identifies camphene by CAS number 79-92-5 and formula C10H16. It contains carbon and hydrogen, with no oxygen. That makes it a terpene hydrocarbon.

If you are comparing aroma ingredients, the full compound name matters more than a shared scent description. Our terpenes vs. terpenoids guide explains why some familiar aroma compounds contain oxygen while others do not.

What does camphene smell like?

The FEMA Flavor Library lists camphene as ingredient 2229, with descriptors including camphor, oil and warm. These are reference points for describing an aroma, not a list of ingredients hidden inside camphene.

“Camphor-like” is a useful smell comparison, but it does not make the compound camphor. A scent description alone cannot identify a chemical or establish the contents of a product.

What is camphene used for?

Camphene is documented as a flavoring agent. The JECFA evaluation found no safety concern for its evaluated flavoring use at then-current intake levels.

That conclusion has a defined scope. It is not a blanket safety finding for every concentration, product or route of exposure, and it does not establish that inhaling a concentrated aroma ingredient is safe.

Camphene vs. camphor vs. borneol

NIST records distinguish camphor and borneol from camphene. Similar names and overlapping aroma vocabulary do not make these ingredients interchangeable.

In this context, “alcohol” describes a chemical group in borneol. It does not mean drinking alcohol. The borneol guide also explains how borneol differs from isoborneol.

What does research say about camphene benefits?

Camphene has been investigated for effects on blood lipids. A 2011 study published in PLOS ONE tested camphene in rats with experimentally induced high blood lipids and in cultured HepG2 cells.

The researchers reported lower cholesterol and triglyceride levels in the rat experiment. They also investigated how the response differed from inhibition of HMG-CoA reductase, an enzyme targeted by statins.

This was preclinical research, not a clinical trial showing that camphene improves cholesterol in people. It does not establish an effective human dose or show that smelling camphene, using a terpene blend or choosing a product containing it produces the same outcome.
