Uses	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. less more

Raw materials And Preparation Products

Hazard Information

Chemical Properties

Obtained by steam distillation with yields of approximately 0.5 to 1.2% from the fresh, flowering tops. It has a characteristic odor of rosemary and a warm, camphoraceous taste. Spanish rosemary essential oil has the largest production.

Chemical Properties

Rosemary oil is obtained by steam distillation of the twigs and flowering tops of Rosmarinus officinalis L. (Lamiaceae). It is an almost colorless to pale yellow liquid with a characteristic, refreshing, pleasant odor.
d²⁰₂₀ 0.892–0.910/0.907–0.920; n²⁰_D 1.4640–1.4720/1.4640–1.4700; α²⁰_D ?6 ° to +8 °/?2 ° to +5 °; solubility: 1 vol in max. 3 vol 90% ethanol/1 vol in max. 2 vol 80% ethanol (Spanish/North African oil types).
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.

Chemical Properties

Rosemary oleoresin is a purified extract of rosemary from which nearly all of the characteristic rosemary odor and flavor have been removed, leaving a faint note of cooked herbs. Also see Rosemary.

Physical properties

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).

Definition

Extractives and their physically modified derivatives. Rosmarinum officinalis, Labiatae.

Preparation

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.

Composition

Rosemary oleoresin contains antioxidants, which retard the oxidation of lipids (rancidity). Two of the compounds reported from oleoresin are rosmarinic acid and rosmaridiphenol.
