説明
Geranyl acetate has a pleasant, flowery odor reminiscent of rose
lavender. It has a burning taste, initially somewhat bitter and then
sweet. It is produced from geraniol by acetylation or by fractional
distillation of essential oils in which it is present.
化学的特性
Geranyl Acetate occurs in varying
amounts in many essential oils: up to 60% in oils from Callitris and Eucalyptus
species and up to 14% in palmarosa oil. A smaller amount occurs in, for example,
geranium, citronella, petitgrain, and lavender oils. Geranyl acetate is a liquid with
a fruity rose note, reminiscent of pear and slightly of lavender. It is used frequently
in perfumery not only to create floral, fruity nuances (e.g., rose) but also for citrus
and lavender notes. A small amount is added to fruit aromas for shading.
