The major constituents are 1,8-cineole (16–23%/38–55%), ??-pinene
(18–26%/9–14%), and camphor (12.5–22%/5–15%) (Spanish/North African
oils). Verbenone is usually a trace constituent in North African oils
(0–0.4%), but occurs in Spanish oils in quantities between 0.7% and 2.5%.
The main producers of rosemary oil are Tunisia,Morocco, and Spain, with total
～120 t annually. Rosemary oil is used widely in perfumery and in large amounts
for perfuming bath foams, shampoos, and hair tonics.
Physikalische Eigenschaften
It is a colorless or pale-yellow liquid with varying physical–chemical constants, depending on the source.
Occurrence
Found in the flowering tops of Rosmarinus officinalis L. (Fam. Labiatae).
Verwenden
rosemary oil is credited with anti-septic properties, it is also used for masking odor and providing fragrance. Rosemary oil is considered beneficial for acne, dermatitis, and eczema. Some reports indicate that rosemary oil may stimulate fibroblast growth with a possible increase in epidermal cell turnover. This would make it useful in products for aging and mature skin. Rosemary oil, obtained through distillation of the herb’s flowering tops, is superior to that obtained through distillation of the stems and leaves. The latter process, however, is more common among the commercial oils.
synthetische
By steam distillation of the fresh flowering tops of Rosmarinus officinalis L. Uses: In public use before the 1860s. Use in fragrances in the USA amounts to about 50,000 lb/yr.
Essential oil composition
Main constituents include α-pinene, camphene, cineol, camphor and bornyl alcohol (10 to 15%). The volatile or essential oil of rosemary is also reported to include 1,8-cineole, α- and β-pinene, camphor, bornylacetate, camphene, linalool, d-limonene, borneol, myrcene, terpineol and caryophyllene.
Sicherheitsprofil
Low toxicity by ingestion and skin contact. A skin irritant. When heated to decomposition it emits acrid smoke and irritating fumes. See also indvidual components.
