Dive into the world of linalool, a natural compound found in plants, exploring its properties, sources, applications, health benefits, and environmental impact.
Linalool: An Overview
Linalool, a naturally occurring terpene alcohol found in many plants and flowers, possesses a variety of applications due to its distinctive scent and wide range of benefits. The properties of this versatile compound have made it a prevalent ingredient in several industries, such as cosmetics, food and beverage, and pharmaceuticals.
Chemical Properties and Structure
Scientifically known as C10H18O, linalool has a molecular weight of approximately 154.25 g/mol. The molecule exhibits chirality, meaning it has two enantiomers – (R)-(-)-linalool, also known as licareol, and (S)-(+)-linalool, or coriandrol. These enantiomers differ in their optical rotation but share the same structural formula. The varying chemical compositions can lead to different scents and effects; for instance, licareol has a woody lavender scent, while coriandrol has a sweet, floral aroma reminiscent of coriander.
