Lavender and Lavandin oil compositions may benefit from the topnote created with this alcohol, and certain floral bouquets can be improved with pleasantly green, sweet and natural notes from the subject material. It finds increasing use in artificial Geranium oils.
In flavors, traces are used in fruit complexes, and it is a common ingredient in artificial Strawberry. It adds freshness to Mint compositions, and it is often used to reconstitute the flavor in Orange juice, whose flavor suflers severely during the processing.
