A composition comprising a mixture of isomers of 17-oxabicyclo[14.1.0]heptadec-8-ene, having a content of an (E)-17-oxabicyclo[14.1.0]heptadec-8-ene isomer (1) and/or (2),
- wherein
- a) if the isomer mixture contains four isomers (1), (2), (3) and (4), the content of isomer (1) is greater than 32 wt. % and/or the content of isomer (2) is greater than 12 wt. %,
