Calamus root essential oil, also known as "Sweet Flag", is a pale yellow liquid displaying a smooth, warm, woody-earthy-spicy bouquet with a milky, sweet undertone of very good tenacity. You have never smelled anything quite like this lovely rare oil. Our calamus oil is wonderful for adding complex and interesting notes to a scent. It's gentle spice is vaguely reminiscent of the scent of cinnamon bark floating on the air while its earthy tones are well rounded and subtle. Calamus oil can contain around 70% asarones which are highly restricted by IFRA in natural oils to 0.01% of a finished product, however this Payan Bertrand speciality still allows for a maximum use of 0.47% in your finished product. Despite the restrictions this is still a wonderful material to have in the perfumer's palette and is most certainly still useable in commercial scents.
