У парфумерії
It is one of the most frequently used lactones in perfumes and flavors. It is used in tropical fruit complexes and also in coconut, peach, apricot, vanilla, maple, honey and chocolate flavors. Its power is often underestimated by a perfumer without experience as a flavorist, and the lactone will then grow out of the perfume and dominate the fragrance unpleasantly.
