Linalool (LL)

Linalool is a naturally occurring terpene alcohol chemical found in many flowers and spice plants with many commercial applications, the majority of which based on its pleasant scent. It has other names such as β-linalool, linalyl alcohol, linaloyl oxide, p-linalool, allo-ocimenol, and 2,6-dimethyl-2,7-octadien-6-ol. In higher plants linalool, as other monoterpenoids, is produced from isopentenyl pyrophosphate via the universal isoprenoid intermediate geranyl pyrophosphate, through a class of membrane-bound enzymes named monoterpene synthases. One of these, linalool synthase (LIS), has been reported to produce (S)-linalool in several floral tissues. Linalool is used in some mosquito-repellent products, however the EPA notes that: "A preliminary screen of labels for products containing Linalool indicates that efficacy data on file with the Agency may not support certain claims to repel mosquitos."
