Overview
Cedarwood oil is a steam-distilled essential oil derived from the wood of various cedar tree species, primarily Cedrus atlantica, Cedrus deodara, and Juniperus virginiana. With its distinctive woody and balsamic aroma, it has been valued since ancient times for its therapeutic and preservative properties. The oil's composition varies by species but typically contains sesquiterpenes like α-cedrene and cedrol. Modern B2B procurement typically offers quantities starting from 1kg, catering to manufacturers in the fragrance, pharmaceutical, and pest control industries.
Physical and Chemical Properties
Cedarwood oil presents as a viscous liquid ranging from pale yellow to deep amber, with density slightly lower than water. Its low volatility contributes to its role as a fixative in perfumery. The oil's insolubility in water necessitates alcohol or oil carriers for most applications. Key chemical markers include thujopsene (6-25%) and cedrol (10-30%), which contribute to its antimicrobial and insect-repellent properties. Gas chromatography (GC) analysis is recommended for quality verification, as adulteration with synthetic compounds or carrier oils is common in commercial grades.
Main Applications
In aromatherapy, cedarwood oil is prized for its calming effects and use in respiratory blends. The fragrance industry utilizes it as a base note in masculine scents, soaps, and incense. Its natural insect-repellent properties make it valuable for moth-proofing woolens and formulating non-toxic pest control products. Industrial applications include wood preservation and as a flavoring agent in food products (in highly purified forms). Recent studies explore its potential in dermatological preparations for acne and eczema treatment due to its antimicrobial and anti-inflammatory compounds.
Safety and Storage
Undiluted cedarwood oil may cause skin irritation in sensitive individuals. Proper storage requires amber glass or aluminum containers to prevent photodegradation, with ideal temperatures between 15-25°C. The oil has moderate oxidation stability, typically maintaining quality for 2-3 years when stored correctly. Material Safety Data Sheets (MSDS) classify it as flammable liquid Category 4. Workplace exposure limits have not been established, but adequate ventilation is recommended during large-scale handling. Disposal should follow local regulations for essential oils.
B2B Procurement Guide
When sourcing cedarwood oil, specify the botanical source (Atlas, Himalayan, or Virginia cedar) as chemical profiles differ significantly. Request GC-MS analysis certificates verifying ≥90% purity. For organic applications, USDA/EU organic certifications are essential. Minimum order quantities (MOQs) commonly start at 1kg for small-scale buyers, with bulk discounts available at 25kg+ quantities. Lead times vary by origin, with Himalayan cedarwood typically requiring longer procurement cycles. Consider incoterms carefully as international shipments may require special hazardous materials documentation.
