Abstract

The invention relates to a vetiveryl ester comprising at least 0.5 weight percent of secondary alcohol compounds with respect to the total weight of the vetiveryl ester and to a process for the preparation a vetiveryl ester, the process comprising: providing a vetiver oil, at least one enzyme preparation and at least one acylating compound; and allowing sufficient time for the enzyme preparation to esterify the alcohol compounds of the vetiver oil with the acylating compound. The invention also relates to a vetiveryl ester obtainable by the above process, a fragrance composition comprising anabove-mentioned vetiveryl ester and the use of an above-mentioned vetiveryl ester for the preparation of a perfumed product.

Description

technical field [0001] The present invention relates to vetiveryl esters, a method for preparing vetiveryl esters, a fragrance composition comprising vetiveryl esters and uses of the above-mentioned vetiveryl esters, vetiver prepared by the above-mentioned method Esters, or the above fragrance compositions for the preparation of perfuming products. Background technique [0002] Vetiver oil is a composition extracted from Vetiver grass (Vetiveria zizanioides) (Poaceae), also known as Chrysopogon zizanioides. Extracts obtained from Vetiver (Poaceae) and modified extracts such as tinctures, coagulations, absolute oils, essential oils, oleoresins, terpenes, terpene-free fractions, residues, etc. are also known (CAS: 84238- 29-9; EINECS: 282-490-8). Vetiver oil is also used as a substrate to provide fragrance ingredients and compositions, such as vetiver extract (CAS: 84082-84-8; EINECS: 282-031-1), vetiveryl acetate (CAS: 62563-80-8; EINECS: 204-225-7, 263-597-9), vetiverol (...
