Citronellol, or dihydrogeraniol, is a natural acyclic monoterpenoid. Both enantiomers occur in nature. (+)-Citronellol, which is found citronella oils, including Cymbopogon nardus (50%), is the more common isomer. (−)-Citronellol is found in the oils of rose (18-55%) and geranium.[1]

Citronellol is used in perfumes and insect repellents,[2] and as a mite attractant.[3]


The United States FDA considers citronellol as GRAS (Generally Recognized as Safe for food use).[3] Citronellol should be avoided by people with perfume allergy.[4]
