Definitions

  • the present invention relates primarily to certain perfume mixtures, preferably perfume oils, comprising a compound of the formula (I) (tricyclo [5.2.1.0] decane-8-ethyl ether)

  • the compound of the formula (I) is known to the person skilled in the art (CAS No. 13213-08-6, see also Zhurnal Obshchei Khimii (1964), 34 (6), 2081-4).
  • An odor description of the compound of the formula (I) can be found in DE 3501888 C2.
  • the compound of formula (I) is described there as strong, warm woody, strongly radiant and with a note pronounced of forest foliage.
