Bio-based Chemicals from Camphor Trees & Cinnamon
Rosewood & Camphora
Rosewood in China is the top-class wood materials of classical furniture and accessories. Meanwhile, in history of fragrance industry, the time flows back to 1870s, the natural linalool, a high-contain substance in rosewood oil, was extracted from rosewood on French Guiana. Natural linalool has flora character and show pretty green scent, it became one of the favorite ingredients on fragrance industry. The early production was extracted from Brazil rosewood oil (Aniba rosaeodora Ducke, French: Bois-de-rose) and Mexico linaloe oil (Bursera delpechiana). After the World War II, the demand for linalool can not be met by the wood oils’ production. In 1992, Brazilian rosewood gained CITES protection.1
However, the synthetic grade linalool’s sensory features do not pander to the sensitive demands from fragrance industry. “It lacked the fine, intricate shading of organoleptic impression that the natural products displayed due to the presence of its trace amounts of impurities.2” In the 1970s, the fragrance manufactures focus on SEA, the Cinnamomum camphora L. presl (Chinese Ho-wood).

There are five commercial type camphor trees in China. Following active compounds were extracted from leaves for used as medicine intermediates and fragrance materials.
- Linalool-type: for extracting l-Linalool.
- Cineol-type: for extracting 1,8-cineole.
- Camphor-type: for extracting natural camphor.
- Isonerolidol-type: for extracting isonerolidol.
- Borneol-type: for extracting d-Borneol.
Cinnamomum. contains high purity of phytochemicals. The herb active compounds have properties on antimicrobial, pest control and treat activities.
Phytochemicals often have optical isomers, and the application of the isomers can fully exert its natural medicinal value.
Broad Spectrum Antibacterial
The volatile oils of plants often have broad-spectrum antibacterial properties, and are eco-friendly ingredients used on the home care product formulas.
