Chemistry & Uses
Year of discovery :
Terpineol's structure determined in 1885 by Wallach, Tiemann and Semler.
Natural availability :
Terpineol can be obtained from the essential oil of many plants by fractional distillation, such as Turpentine EO, Lavender EO, Wormwood EO, Cardamom EO or Clary Sage EO. It is therefore posible to have a natural quality. This ingredient is found, in large quantities or in trace, in a very large quantity of ingredients used in our fragrances. Some references identify more than 200 oils containing it.
Isomerism :
Terpineol is a mixture of isomers. There are four of them. The alpha-terpineol ; beta-terpineol ; gamma-terpineol as well as terpinen-4-ol.
Synthesis precursor :
Terpineol is a precursor for the synthesis of a large number of olfactory compounds.
Synthesis route :
There are several ways to obtain Terpineol. Either by isolation from a natural ingredient, or by synthesis. The most commonly used reaction mechanisms start with Turpentine EO, alpha-pinene or D-Limonene
Stability :
Data not available.
Other comments :
Terpineol, along with menthol-l and carvone-l, is one of the three most important cyclic monoterpenes used in perfumery. Precursor to the synthesis of many other ingredients and present at least trace in most natural extracts, terpineol is essential in perfumery.
The quality presented here comes from a Upcycling program and is 100% renewable carbon.
