Rlinalool

Rlinalool, commonly written as R-linalool, is one enantiomer of linalool, a naturally occurring monoterpene alcohol with the formula C10H18O. Like its mirror image, S-linalool, R-linalool is produced by many plants and exhibits optical activity. In nature, linalool is biosynthesized from geranyl pyrophosphate via linalool synthase in a range of species.

R-linalool is a major component of numerous essential oils and occurs in varying proportions depending on the source. It is found in lavender, coriander, bergamot, citrus peel oils, rosewood, and many other essential-oil streams. Commercial linalool is often supplied as a racemate (RS-linalool) or in enantiomerically enriched forms.

Odor and applications: Linalool has a pleasant floral scent with citrus undertones and is widely used as a fragrance ingredient and flavor additive. It is a common constituent of perfumes, soaps, detergents, and cosmetics, frequently serving as a top or middle note. The sensory properties can differ between enantiomers, and enantiomeric composition can affect aroma in some blends.

Production and regulation: Industrially, linalool is produced by extraction from essential oils or by chemical synthesis and then purified; chiral separation may yield enriched R- or S-linalool. Safety and regulation: Linalool is generally regarded as safe as a flavoring agent and is permitted in cosmetics in many jurisdictions. However, linalool and especially its oxidized products can be skin sensitizers, and several regions require labeling of linalool as a fragrance allergen in consumer products.
