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.”
