How is citronellol produced?
(-)-Citronellol is still obtained mainly from geranium oil by saponification followed by fractional distillation. In the second method, citronellol is produced by catalytic hydrogenation of saponified geraniol fractions obtained from Java citronella oil, followed by fractional distillation.
What is citronellol derived?
Citronellol is a naturally derived ingredient that is added to cosmetics and personal care products as a fragrance due to its sweet, floral scent. Citronellol, which is found in citronella oils, in the oils of rose and geranium oil.
What is the site of essential oil biosynthesis and accumulation?
Essential oil (monoterpene) biosynthesis and accumulation in mint is specifically localized in epidermal oil glands (12, 26).
Where is citronellol found?
Jacobsen in 1871. Its structure is similar to that of nerol, also a rose scent ingredient. Citronellol exists in nature as two enantiomers, designated (+) and (–). The (+)-isomer is more common and takes its name from citronella oils.
What is the functional group of citronellol?
From the skeletal structure we can see that (‐)‐citronellol contains both alkene and primary alcohol functional groups. All the carbon atoms have a tetrahedral shape apart from the two carbon atoms in the carbon‐carbon double bond, which, like an aldehyde, are trigonal planar, or flat.
What is the purpose of citronellol?
Uses. Citronellol is used in perfumes and insect repellents, and as a mite attractant. Citronellol is a good mosquito repellent at short distances, but protection greatly lessens when the subject is slightly further from the source.
How are Nerol and geraniol related to citronellol?
Geraniol is monoterpene alcohol that is a main ingredient of rose oil; it also is present in many other essential oils. Its structure is similar to that of nerol, also a rose scent ingredient. Citronellol exists in nature as two enantiomers, designated (+) and (–).
Why is oil called ethereal oil?
An essential oil is a concentrated hydrophobic liquid containing volatile (easily evaporated at normal temperatures) chemical compounds from plants. Essential oils are also known as volatile oils, ethereal oils, aetheroleum, or simply as the oil of the plant from which they were extracted, such as oil of clove.

How is citronellol used as an insect repellent?
Citronellol can be prepared by hydrogenation of geraniol or nerol. Citronellol is used in perfumes and insect repellents, and as a mite attractant. Citronellol is a good mosquito repellent at short distances, but protection greatly lessens when the subject is slightly further from the source.
What kind of raw material is citronellol used for?
Citronellol is used as a raw material for the production of rose oxide. The United States FDA considers citronellol as generally recognized as safe (GRAS) for food use.
Which is the most common isomer of citronellol?
Both enantiomers occur in nature. (+)-Citronellol, which is found in citronella oils, including Cymbopogon nardus (50%), is the more common isomer. (−)-Citronellol is found in the oils of rose (18–55%) and Pelargonium geraniums. Citronellol can be prepared by hydrogenation of geraniol or nerol.
Can a person have an allergic reaction to citronellol?
Citronellol is subject to restrictions on its use in perfumery, as some people may become sensitised to it, but the degree to which citronellol can cause an allergic reaction in humans is disputed. ^ Lawless, J. (1995). The Illustrated Encyclopedia of Essential Oils.
