Linalool
Description
Linalool is used very extensively in perfume compositions of almost all types and price levels. Basically a floral material, and originally a Lily-of-the V alley (Muguet) ingredient, it is now used in countless floral types, and in Oriental, Ambre, aldehydic, herbaceous and many other fragrance types. It may even form part of a Citrus fragrance or a woody complex, a Lily, Muguet, Honeysuckle, Lilac, Sweet Pea, NeroIi, Appleblossom, Frangipanni, Freesia, Peony, etc. Linalool should be the ingredient that gives the lift in an overall heavier composition.
