天然物の起源
Found in the flowering tops of Rosmarinus officinalis L. (Fam. Labiatae).
使用
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.
製造方法
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.
