Composition


The composition of orange oil varies for several reasons. Region and seasonal changes as well as the method used for extraction lead to these variations. Several hundred compounds have been identified with gas chromatograph-mass spectroscopy. Most of the substances are part of the terpene group with limonene

Safety


The limonene which is the main component of the oil is a mild hand irritant, by virtue of dissolving the protective oils in the skin. It is wise to wear solvent-resistant gloves when handling limonene solutions.

Limonene and its oxidation products are skin irritants, and limonene-1,2-oxide (formed by aerial oxidation) is a known skin sensitizer. Most reported cases of irritation have involved long-term industrial exposure to the pure compound, e.g. during degreasing or the preparation of paints. However a study of patients presenting dermatitis showed that 3% were sensitized to limonene.

Treating Termite Infestations

Orange oil is increasingly being used as an alternative to more traditional methods of ridding a house of termites, such as tenting or using other dangerous pesticides. The benefits of an orange oil treatment include: occupants do not have to leave, the fumes are safe for people, pets, and plants, and the treatment does not leave behind toxic residue or fumes. The cons are: orange oil only kills the termites that the termite inspectors find and spray directly, it doesn't kill termites in the ground (or there's no guarantee that they'll get all of the underground termites), and the poison doesn't last long meaning that the building can be re-infested later.
