Arctander points out that: “olibanum resinoid is a valuable fixative, but it also lends its own peculiar odor to the perfume (see odor description under olibanum oil and absolute), since the essential oil content is only about 8%, the resinoid of olibanum has a much more versatile application in perfumery than has the essential oil.”
