According to the ASPCA, research has shown that a citronella collar can be at least as effective for eliminating barking as an electronic collar, and its typically viewed more positively by dog owners. It is considered for these deletion strains that the oxidation to geranic acid and citronellic acid was suppressed and, instead of it, the metabolic flow from geraniol was directed to the reduction to citronellol. It has low solubility in water, but it is soluble in common organic solvents. Additionally, studies have found that it it can be used in mouthwashes to kill harmful bacteria in the mouth, and it has a lower cytotoxic effect and higher action compared to some other commercial solutions.

Seasonal metabolic profiling of Valencia orange leaf essential oil using GC coupled with chemometrics, nano-formulation, and insecticidal evaluation: Neuromodulation and differential learning across mosquito species. Is citronella oil effective against mosquitoes? These data suggest that BY4741 enzymes related to metabolism of monoterpene alcohols have higher affinities to geraniol than nerol. This product should be used only as directed on the label. Among the 5 monoterpene alcohols described above, geraniol is considered to be more cultivar-specific than linalool. Studies on essential oil from rose-scented geranium. This work was supported by a research fund to I.M. To clarify the metabolic pathways from geraniol/nerol to geranic acid and from geraniol/nerol to citronellic acid, potential substrates for biosyntheses of geranic acid and citronellic acid were added to BY4741 culture.
