superabsolute

— By extraction of the pomades and concretes with absolute alcohol, chilling, filtering, fractionally distilling under reduced pressure at low temperatures, and by other means familiar to the organic chemist, are prepared the so-called "absolute" and "superabsolute essences," which represent the highest concentration of the fragrant floral principles. But for the ordinary purposes of the perfumers’ art this high degree of purification is not considered necessary.
