B-Citronellol is a colorless liquid with low water solubility but high solubility in organic solvents.

B-Citronellol is formally classified as alkylalcohol although it is biochemically a monoterpenoid as it is synthesized from isoprene units. 

B-Citronellol is found in highest concentrations in gingers, sweet basils, and winter savories and in lower concentrations in highbush blueberries, bilberries, and cardamoms.

B-Citronellol is a naturally occurring monoterpenoid alcohol widely found in essential oils such as rose, citronella, and geranium oils.

B-Citronellol is characterized by a pleasant, sweet, and floral aroma, making it a valuable ingredient in the fragrance, cosmetic, and food industries.

B-Citronellol is a colorless liquid with low water solubility but high solubility in organic solvents.

In food applications, B-Citronellol is used in very low concentrations as a flavoring agent to enhance sensory properties.

Additionally, B-Citronellol exhibits mild antimicrobial and insect-repellent properties.

B-Citronellol has a role as a plant metabolite.

B-Citronellol has been reported in Ambrosiozyma monospora, Artemisia princeps, and other organisms with data available.

B-Citronellol is a metabolite found in or produced by Saccharomyces cerevisiae.

B-Citronellol is formally classified as alkylalcohol although it is biochemically a monoterpenoid as it is synthesized from isoprene units. 

B-Citronellol occurs in many essential oils as either - or + enantiomers. 

B-Citronellol is found in the oils of rose (18-55%) and Pelargonium geraniums while + citronellol is found in citronella oils extracted from the leaves and stems of Cymbopogon nardus or citronella grass. 

B-Citronellol is found in highest concentrations in gingers, sweet basils, and winter savories and in lower concentrations in highbush blueberries, bilberries, and cardamoms. 

B-Citronellol has a citrus, floral, and geranium taste with a floral¬†leathery¬†waxy¬†rose¬†citrus odor ( Ref:DOI).  

B-Citronellol is an insect repellent that repels mosquitos at short distances. 

B-Citronellol has also been detected in blackcurrants, fennels, evergreen blackberries, herbs and spices, and nutmegs making citronellol a potential biomarker for the consumption of these foods. 

Uses of B-Citronellol:

B-Citronellol is widely used across multiple industries due to its pleasant floral aroma and functional properties.
