Citronella oil is one of the essential oils obtained from the leaves and stems of different species of Cymbopogon (lemongrass). The oil is used extensively as a source of perfumery chemicals such as citronellal, citronellol, and geraniol. These chemicals find extensive use in soap, candles and incense, perfumery, cosmetic, and flavouring industries throughout the world.

Citronella oil is also a plant-based insect repellent and has been registered for this use in the United States since 1948.[2] The United States Environmental Protection Agency considers oil of citronella as a biopesticide with a non-toxic mode of action.[3] However, citronella insect repellant effects were not proven within the EU, and the use of citronella as an insecticide is prohibited under the Biocidal Product
