d²⁵₂₅ 0.910-0.920; n²⁰_D 1.4560-1.4590; α²⁰_D ?14 ° to ?10 °; ketone content (calculated as thujone): min. 60 %; solubility: 1 vol in 3 vol of 70% ethanol at 25℃.
The oil is produced in the northern states of the United States and in Canada in a quantity of 20–30 t/yr. It is used in perfumery for dry nuances in citrus and woody compositions.

Chemical Properties

The volatile oil obtained by steam distillation from the fresh leaves and branches of at least 15-year-old plants. It has a strong, camphoraceous odor reminiscent of sage and a similar taste.

Chemical Properties

Pale-yellow essential oil; camphor-like odor. Soluble in alcohol, ether, chloroform, carbon disulfide, fixed oils, and mineral oil. Combustible. Chief known constituents: Dextro-pinene, levofenchone, thujone, should contain more than 60% ketones calculated as thujone.

Physical properties

It is a colorless to yellow-greenish liquid. It is soluble in most fixed oils, in mineral oils and propylene glycol. It is practically insoluble in glycerin.

Occurrence

Found in the leaves and branch ends of Thuja occidentalis L. (Fam. Cupressaceae).

Uses

As fragrance in soaps, detergents, perfumes.

Definition

An essential oil distilled from the leaves of Juniperus virginiana. Strongly dextrorotatory. Used in microscopy, perfumery, flavoring.

Preparation

By steam distillation of the fresh branch ends and leaves.

Essential oil composition

The chief constituent of cedar leaf oil is d-a-thujone

Safety Profile

Moderately toxic by ingestion and skin contact. A skin irritant. Ingestion of large quantities causes hypertension, bradycardia, tachypnea, convulsions, death. When heated to decomposition it emits acrid smoke and fumes. See also ARTEMISIA OIL.
