Geranyl acetate is a naturally occurring chemical compound and the ester of geraniol and acetic acid . The acyclic monoterpenoid is a component of essential oils such as coriander , lemon , orange and lavender oils .

Properties and use

Geranyl acetate is a colorless liquid with a flowery, rose- like odor and a burning, sweetish-bitter taste. The flash point is 104 ° C. The density is 0.91 g · cm −3 . Geranyl acetate is formed when geraniol is esterified with acetic acid . The ester is mainly used as an odor component in perfumes , deodorants and also in food. In the USA the ester is classified as FEMA GRAS ( Generally Reported As Safe ); the permitted daily PADI dose is 3,090 milligrams per day.
