Hazard Information

Description

Cinnamomum Camphora Linaloolifera Leaf Oil is the volatile oil obtained from the leaves of Cinnamomum camphora var. linaloolifera (Lauraceae)

Chemical Properties

The leaf oil (ho leaf oil) contains up to 80% linalool; the oil does not contain free crystalline camphor. The oil is steamdistilled from the leaves and has a sweet, floral, delicate odor reminiscent of linalool. Also see Camphor, Tree.

Chemical Properties

The oil is obtained by steam distillation of chipped wood using rudimentary stills with a perforated bottom to avoid prolonged contact of the material with the boiling water; this results in extensive hydrolysis of the ester content (linalyl acetate). The essential oil is obtained in high yields (8% or more). The oil has a pleasant, rose-like slightly camphorous odor. An essential oil is also steam-distilled from the fruits in approximately 3% yields. The oil differs in chemical composition from linaloe wood oil for its content of dextrorotatory linalool.

Physical properties

The wood oil is a colorless to yellow liquid. It is soluble in propylene glycol and most fixed oils. It is soluble in mineral oil, but becomes turbid on dilution. The oil is insoluble in glycerin.

Occurrence

Found in the leaves of the tree Cinnamomum camphora L. Nees & Ebermeier (Fam. Lauraceae) (Fenarolis Handbook of Flavor Ingredients, 1971).

Definition

Extractives and their physically modified derivatives. Cinnamomum camphora, Lauraceae, ho-sho

Preparation

By steam distillation of the leaves of Cinnamomum camphora Sieb. (Fenarolis Handbook of Flavor Ingredients, 1971).

Questions And Answer

Application

1. Linalool, a component of Ho oil, has a global annual demand of 28,000 tons, making it the most widely used and consumed fragrance ingredient in the world today. It is mainly used in the formulation of fragrances and in the synthesis of carotene and vitamins, among other fine chemicals. According to statistics from the American International Fragrance Company, linalool is the most frequently used fragrance ingredient in perfume, household chemical, and soap fragrance formulations, with a current global annual consumption of over 10,000 tons.
2. Camphor in Ho oil has a strong camphor aroma and a spicy taste. It can be used in medicine and in the production of insecticides, moth repellents, blade narrowers, stabilizers, etc. It is widely used in the production of traditional Chinese medicine and can be formulated into cardiotonic drugs, Ten Drops Water, Rendan, and cooling oil. Medicinally, it has the effects of clearing the orifices and relieving pain. High-purity natural camphor can be used as a stabilizer to slow down the combustion rate of smokeless gunpowder. It can also be used as a major raw material for the production of bromocamphor and sodium camphor sulfonate. The oil extracted from the leaves of the linalool tree (linalool leaf oil) also mainly contains linalool. Acetylated linalool leaf oil can be used as a supplement to mixed lavender oil.
3. Eucalyptus oil in Ho oil has a fresh, diffusive, and camphor-like cool aroma. It is widely used in food flavorings, especially as a flavoring ingredient in cough syrups and oral hygiene products.
