The oil of Eucalyptus Australians exists in several forms apart from the type tree. We shall describe only the type and the variety called "B". The two oils are produced in sizeable quantities in southern Australia and the trees have lately been introduced in the Union of South Africa. The oils are produced locally by steam distillation of fresh or semi dry leaf material. Both oils are colorless or pale yellow, mobile liquids. Eucalyptus Australiana type is a cineole type of oil, slightly different from the common pharmaceutical eucalyptus oils, however, it has a peculiar sweet dryout and has less of the unpleasant low aldehydic topnotes characteristic of most of the pharmaceutical cineole type oils. It finds some use as a perfume material in the industrial perfumes.
