Chemistry & Uses
Uses in perfumery :
Cedrol is used in woody, leather and masculine notes and perfumes, to give a dry, ashy and sawdust effect.
Year of discovery :
Data not available.
Natural availability :
Cedrol is present in a few cedarwood oils, of various species. All species are called ''cedarwood '' because of their content of Cedrol, even if they are not cedarwoods, botanically speaking. Cedarwood Virginia EO contains between 16 and 25% of Cedrol. Cedarwood Texas EO is the one containing the most Cedrol, with 20% minimum. Eventually, Cedarwood Chinese EO can contain 10 to 20% of Cedrol. Cedarwood Atlas EO, coming from Morocco, does not contain Cedrol.
Isomerism :
Cedrol has a few asymmetric carbons. In general, dextrorotatory Cedrol is used in perfumery, because it is the one present in cedarwood oils. Here, we are talking about this enantiomer. Synthetic Cedrol can be a mix of levorotatory and dextrorotatory Cedrol. Cedrol is also a constitutional isomer of Polysantol® and Javanol®, even if their smell is more reminiscent of sandalwood than cedarwood.
Synthesis precursor :
Cedrol is a precursor to the synthesis of some components used in perfumery. For example, Cedryl acetate is obtained by an esterification reaction involving Acetic Anhydride and Cedrol. Also, a methylation reaction of Cedrol leads to the formation of Cedramber®.
Synthesis route :
Cedrol is generally extracted from cedarwood oils (cf. ''Natural Occurrence ''). Synthesis of Cedrol is not frequent. Extraction of Cedrol leads to a colored and liquid aspect of the molecule, which is not obtained on a pure state. For natural Cedrol, the percentage of Cedrol contained in the sold product has to be mentioned.
Stability :
Stable in perfumes and diverse functional bases.
Other comments :
Pure Cedrol is a solid. When extracted from cedarwood, Cedrol can be found under a liquid form, mixed with other oily components. It is then very viscous and tends to crystallize easily.
