Is linalool toxic to humans?
Linalool is a “generally recognized as safe” (GRAS) substance approved by the FDA as a direct food additive (synthetic flavoring substance) for human and animal consumption (FDA, 1996). Despite the widespread exposure to linalool, few studies of its effects on humans have been conducted.
How does linalool affect the body?
For instance, linalool reduces the signaling strength of acetylcholine, a brain chemical that’s required for muscle contraction and movement. Linalool can have anesthetic-like effects by reducing the excitability of cells in the spinal cord that transmit pain signals to the brain.
What does linalool smell like?

What fruits contain linalool?
Over 200 species of plants produce linalool, mainly from the families Lamiaceae (mint and other herbs), Lauraceae (laurels, cinnamon, rosewood), and Rutaceae (citrus fruits), but also birch trees and other plants, from tropical to boreal climate zones.
Is Lavender a linalool?
Linalool is a noncyclic monoterpenoid that is commonly extracted from lavender (Lavandula spp.), rose (Rosa spp.), basil (Ocimum basilicum), and neroli oil (Citrus aurantium).
Is linalool an alcohol?
Linalool is an alcoholic monoterpene and the main component of O. basilicum oil (46.97%). It has been shown that linalool-rich essential oils extracted from several plants have antimicrobial properties but because of the little effect of linalool alone on T.
What spices contain linalool?
Linalool is an alcohol found in bay, bergamot, coriander, ho wood, basil*, thyme*, lavender, clary sage, sage, cinnamon, petitgrain, rose, niaouli*, sage, neroli, geranium, marjoram, palmarosa, jasmine, ylang, ylang, and rosewood. Alcohols can be sensitizing when oxidized, so proper storage is important.
Do apples have linalool?
Also not surprising is that apple blossoms have their own unique signature that happens to be a bit more floral. They contain high amounts on linalool for example and have small amounts of beta-caryophyllene.
Is linalool optically active?
Linalool is a terpene alcohol, which is present in many plant species EO. It occurs naturally in two isomeric forms, also named enantiomers. The enantiomers are optically active, asymmetrical and non-overlapping isomers that are mirror images of each other.
How do you make linalool?
It can be produced industrially by hemi- synthesis from natural pinene or through total chemical synthesis. Isolation of linalool as a single compound from an essential oil mixture can be achieved by using various chromatographic techniques such as column chromatography or through fractional distillation.
What is the specific rotation of pure linalool?
(R)-(–)-Linalool used had a 21.95% total yield, a 97.0% purity on GLC (CP-cyclodextrine-β-236M-19) and a specific rotation [α]D = –15.1° (c 0.88, ethanol), while (S)-(+)-linalool with a 32.9% total yield, a purity of (S)-form 88.3% and (R)-form 11.7% on GLC and a specific rotation [α]D = +17.4° (c 3.19, ethanol) and ( …
Is linalool soluble in water?
Linalool is a colorless liquid, relatively soluble in water (1590 mg L−1 at 25 ◦C) and highly soluble in different organic solvents. This tertiary terpene alcohol has a chiral center at C3 carbon, thus appearing two enantiomeric forms in nature: (+)-Linalool and (−)-linalool .
Is linalool a Monoterpenol?
What are the two major functional groups present in linalool?
Linalool is a monoterpenoid that is octa-1,6-diene substituted by methyl groups at positions 3 and 7 and a hydroxy group at position 3.
Is linalool safe to consume?
Linalool is a compound that is naturally occurring, found in the essential oils of many flowers and spice plants. It has a safe history of use and has been deemed by both the U.S. Food and Drug Administration (FDA) and the Joint FAO/WHO Expert Committee on Food Additives (JECFA) as safe for use in food and beverages.
What foods are high in linalool?
This is a major constituent of Ho Wood (up to 99%), Rosewood, Thyme linalool chemotype, Coriander seed and Lavender essential oils. It is also found, in VERY much smaller amounts, in apricots, papayas and cranberries.
Is linalool a toothpaste?
For example, limonene and linalool are in toothpaste (see resources) but not all toothpastes are listed so it means looking at the labels and contacting the manufactures for clarification of their products or looking for alternatives.
Does rosemary contain linalool?
