Thanks both of you. Just read that the MAIN components of many lavender oils are in the family of the terpenes, LINALOOL, LINALYL ACETATE, and EUCALYPTOL and the Ketone CAMPHOR. As you imply there are probably many complex constant boiling mixtures. Perhaps I should just try, as with the removal of methanol from fermented fruits, by …….
redistilling my pure 200ml lavender oil, and checking by nose (!) the first 1-2ml which primarily distil over.?? f this is very "campherous", then Bob's your Uncle.
Thanks rolnor, I will check the Ebay links you mention.
