      Arctander has some other suggestions: “floral-green odor, fresher than that of Benzylacetate, more lasting. Stable in soap. Suggested for use in perfumes as a modifier for Benzylacetate, particularly in soap fragrances. Its somewhat sharper character can at times bean advantage for the more robust job of perfuming a soap.”
