About
A monoterpene hydrocarbon found in essential oils, listed in EU Annex III and associated with skin sensitization and respiratory effects.
3-Carene (delta-3-carene) is a bicyclic monoterpene naturally occurring in essential oils such as pine, cedar, and turpentine. It is specifically listed in EU Annex III of the Cosmetics Regulation (ref III/121) due to its potential to cause skin sensitization and allergic contact dermatitis. The SCCS has noted that while data are limited, carene and its oxidation products require caution. It is commonly found as an impurity in fragrance formulations using turpentine or pine-derived materials.
