Do not apply essential oils to eyes or undiluted to mucous membranes. Orange essential oil is flammable and should not be vapourised near sources of heat or open flames. Therefore, candle vapourisers are not recommended. Skin sensitisation and phototoxicity are possible with the essential oils, so exposure to UV light sources should be avoided for at least 12 hours after dermal application. The risk is increased in fair-skinned individuals and when a blend that also contains other phototoxic essential oils is used.
