What is 3-carene?
3-Carene (CAS 13466-78-9), also known as Delta-3-Carene, is a naturally occurring bicyclic monoterpene derived primarily from turpentine and conifer resins.
Where is 3-carene used?
- Printing and packaging: bio-based solvent component in ink formulations with strong solvency for resins
- Personal care: fragrance blends with fresh, sweet, piney character in perfumes, shampoos and cosmetics
- Cleaning and coating formulations: carrier in terpene-based systems
- As a FEMA 3821-listed ingredient it is approved as a flavoring agent in food and beverage applications where pine profiles are required.
Good to know: Food and fragrance applications generally require material meeting FCC or equivalent quality standards; documentation supports flavor-grade compliance.
Commercial specifications

- Higher-purity grades for flavor and fragrance end uses
- Technical-grade material for solvent and industrial applications where lower purity thresholds are acceptable
