Background (engl)

Geraniol is a terpene alcohol that forms the chief part of oil of rose and oil of palmarosa. It is an alcoholic extract obtained from geranium oil. It has a pleasant, sweet, rose-like odor. Most geraniol on the market today is synthetic made by pinene chemistry. Geraniol is a widely used fragrance in soaps, detergents, and cosmetics. It is also a component of natural flavors and essential oils used in flavor compounds. It is found in over 250 essential oils including cintronella and lemon grass. It accounts for over 90% of palmarosa oil and a large portion of geranium and rose oils.
