Eucalyptus Staigeriana Oil

#### Eucaluptus Staigeriana. From the leaves of this tree, an essential oil is obtained by steam distillation and sold under the above name. This oil is one of the few eucalyptus oils produced exclusively outside Australia, although the tree originates in this "home of all eucalyptuses". Distillation is undertaken on plantations in Brazil, in the Union of South Africa (Dundee and Carolina provinces), the Seychelles and in Guatemala. The yield is excellent, far better than the yield from **E. Citriodora **which is an even cheaper oil. Oil of **Eucalyptus Staigeriana **is (according to age and resinification) a pale yellow to dark yellow, somewhat oily liquid of sweet and fresh, fruity- lemony odor. The particular odor of this oil makes it immediately interesting for use in fresh- rosy types of soap perfumes, detergent fragrances, etc. But its stability in soap is not very good. The main constituents, **Citral**** **and geranyl acetate are not exactly noteworthy for stability in soaps unless very skillfully fixed. By various means of chemical stabilization, e.g. partial reduction, condensation with acetone, etc., this oil can be transformed into more generally useful soap perfume materials in the same way as described under citronella oil, eucalyptus citriodora oil, etc. As a source of isolated **Citral**, the staigeriana is of little or no interest: the content is too low (35 to 45 percent), and citral is now produced synthetically in a beautiful quality at an attractive price. Oil of **Eucalyptus Staigeriana **is presently produced in quantities of 15 to 35 metric tons per year, but the production may slowly diminish in the future in view of the above competition. There are only few actual producers of this oil, and they are all earnest settlers, growers and distillers. Adulteration is practically out of the question. ---
