Citronella oil is an essential oil. The oil is used extensively as a source of perfumery chemicals such as citronellal, citronellol, and geraniol.
Citronellal or rhodinal (C10H18O) is a monoterpenoid aldehyde, the main component in the mixture of terpenoid chemical compounds that give citronella oil its distinctive lemon scent.
