Information @ a Glance

  • Linalool is a colorless to very pale yellow liquid with a floral smell similar to that of bergamot oil and French lavender. It is a naturally occurring substance that is used to make fragrances and flavors.

  • Linalool is a naturally occurring terpene alcohol chemical found in many flowersand spice plants with many commercial applications, the majority of which are based on its pleasant scent .

  • Linalool is one of the most important compounds to the perfume and flavor industries and is found in large amounts in several plant species. Since linalool is an important intermediate in the manufacture of vitamin E, large-scale processes have been developed for its production.

  • Linalool and its esters have been identified in the essential oils of several hundred plants.

  • Another very interesting property of linalool is the ease with which it undergoes cyclization. It was discovered in the early stages of the study of linalool that both dilute sulfuric acid" and strong formic acid converted it not only to geraniol and nerol but also to alpha terpin hydrate.

  • Linalool was formerly obtained entirely from natural sources. It was separated from other components of an essential oil by careful fractional distil¬lation through efficient columns.

  • Formerly, synthetic linalool could be prepared only by the method described by Ruzicka and Fornasir in 1919. Both commercial linalool and linalool used in academic studies were obtained from natural sources.

  • A process which has become very important in the production of large quantities of linalool is based on pinene chemistry and has resulted in the availability of many other terpene derivatives.

  • New technologies for extraction, as super critical fluids, would be essential in the production of linalool from species other than rosewood, due its precision in extracting only the wanted substance at low temperatures.

  • Linalool is used as a scent in 60–80% of perfumed hygiene products and cleaning agents including soaps, detergents, shampoos, and lotions. It is also used as a chemical intermediate. One common downstream product of linalool is Vitamin E. In addition, linalool is used by pest professionals as a flea and cockroach insecticide.

  • Linalool is used in large quantities in soap and detergent products, and has been found to be stable and non-discoloring.

  • Linalool can be converted to terpineol, geraniol and citral, and used in the preparation of citronellol, the ionones, Vitamin A, farnesol and sesquiterpenes.

  • The linalool dehydratase catalyzed in vitro two reactions in both directions depending on the thermodynamic driving forces: a water secession from the tertiary alcohol linalool to the corresponding acyclic monoterpene myrcene and an isomerization of the primary allylalcohol geraniol in its stereoisomer linalool.

  • Citrus are a good source of linalool. The Brazilian juice industry produces essential oil as a byproduct from the fruit peels at very low prices, but theirs is poor in linalool.

  • Linalool, like geraniol, is normally a very stable product that follows broad economic trends, but its pricing has softened for the past 18 months, primarily because of weakening prices for its main feedstock, crude sulfate turpentine.

  • The cosmetics industry is becoming increasingly interested in many different, often very specific, essential oils, many of them of tropical origin. The exact demand situation is therefore difficult to characterise.
