Sweet Orange Essential Oil

Citrus sinensis

Introduction

With its versatility, affordability and familiar citrus aroma, Sweet Orange Essential Oil is one of the most popular essential oils used within aromatherapy. It is typically cold pressed from the rind of the sweet orange fruit and has a bright, sweet, fresh orange aroma.

Aromatically, Sweet Orange Essential Oil is a top note that blends well with a wide range of other essential oils. It can soften heavier aromas, brighten blends and add a familiar citrus character without the sharpness associated with some other citrus oils.

Sweet Orange Essential Oil is especially rich in d-limonene. Published analyses commonly report limonene at approximately 90-97% of Citrus sinensis peel essential oil, although the exact composition varies with cultivar, growing conditions, fruit maturity, extraction method and storage. ¹

Because limonene readily oxidizes when exposed to air, Sweet Orange Essential Oil should be stored tightly capped and protected from heat and light. Oxidation products of limonene, particularly limonene hydroperoxides, can be more sensitizing than fresh limonene. ²

Its high limonene content also helps explain why orange oil is frequently used within household cleaning products. d-Limonene is used commercially as a solvent and cleaning agent. ⁵

Sweet Orange vs. Bitter Orange Safety Concern

Sweet Orange Essential Oil and Bitter Orange Essential Oil are different essential oils and should not be treated as interchangeable. Citrus taxonomy and naming can be complex, so check the botanical name, common name, plant part and extraction method supplied with the oil.

Within aromatherapy references, Sweet Orange Essential Oil is generally identified as Citrus sinensis. Robert Tisserand and Rodney Young indicate that Sweet Orange Essential Oil is not phototoxic. Bitter Orange peel oil, however, is phototoxic⁶. This distinction is important when selecting an orange oil for topical use.

Fun Facts About the Cold Pressing of Sweet Orange Essential Oil

Unlike most essential oils that are extracted using steam distillation, most citrus peel oils, including Sweet Orange Essential Oil, are produced by expression or cold pressing of the rind. Steam distilled Sweet Orange Essential Oil is also available, but it is less commonly encountered.

When you peel an orange, you may notice tiny droplets spray from the rind and a burst of orange aroma at the same time. Those aromatic droplets originate from oil glands within the peel. The next time that you peel an orange or another citrus fruit, gently press a portion of the rind between your fingers and notice how intensely aromatic the peel itself can be.

Sweet Orange Essential Oil Benefits and Uses

When I am feeling anxious, stressed or lethargic, I find the aroma of Sweet Orange Essential Oil uplifting and balancing.

There is some human research supporting the traditional aromatherapy use of Sweet Orange aroma for situational anxiety. In a controlled study involving 40 healthy male volunteers exposed to an anxiety-provoking task, the 2.5-drop and 10-drop Sweet Orange Essential Oil conditions showed an anxiolytic pattern on psychological measures compared with the control groups, although the results were not consistent across all three Sweet Orange dose groups and physiological changes were not prevented. The researchers emphasized that additional research is needed to determine its clinical relevance for anxiety disorders. ³

A separate small randomized crossover study involving 30 children during dental treatment found lower salivary cortisol and pulse rate when orange essential oil aroma was used compared with the control condition. ⁴

Sweet Orange Essential Oil Safety Information

Tisserand and Young do not indicate special precautions for fresh Sweet Orange Essential Oil, but they caution against using the oil if it has oxidized. Because limonene can oxidize during storage, keep the bottle tightly closed, protect it from heat and light and avoid using old or oxidized oil. ²

Sweet Orange Essential Oil is not considered phototoxic by Tisserand and Young. This is an important distinction from Bitter Orange Essential Oil, which is phototoxic. Always verify which orange oil you have before topical use.
