Linalool, (-)- is one of enantiomers of Linalool and a fragrance ingredient used in decorative cosmetics, fine fragrances, shampoos, toilet soaps and other toiletries as well as in non-cosmetic products such as household cleaners and detergents. The maximum skin level that results from the use of l-linalool in formulae that go into fine fragrances has been reported to be 0.31%, assuming use of the fragrance oil at levels up to 20% in the final product. Linalool is used by pest professionals as a flea, fruit fly, and cockroach insecticide. It can also be used a method of pest control for codling moths. Linalool creates a synergistic effect with the codling moth's pheromone called codlemone, which increases the attraction of males. Linalool can be absorbed by inhalation of its aerosol and by oral intake or skin absorption, potentially causing irritation, pain and allergic reactions.
