Metabolism / Metabolites
In rabbits this alcohol metabolizes to 7-carboxy-and 7-hydroxymethyl-3-methylocta-6-enoic acids, and these are excreted in the urine.

Toxicity Summary
IDENTIFICATION AND USE: Citronellol has been found in nature, and it has been reported in about 70 essential oils. It is registered for pesticide use in the USA but approved pesticide uses may change periodically and so federal, state and local authorities must be consulted for currently approved uses. It is also used in perfumery. HUMAN EXPOSURE AND TOXICITY: Adult male volunteers with no known allergic reactions were patch-tested on their back for 48 hr with 32% citronellol. After 48 hr, patches were removed and the skin was cleaned of any residual test material. Moderate irritation was observed. A patch test using a 1% concentration of citronellol in acetone gave a positive reaction in subjects allergic to citronella oil. ANIMAL STUDIES: Citronellol applied full strength to intact or abraded rabbit skin for 24 hr under occlusion was moderately irritating. Severe irritation was observed in rabbits and guinea pigs exposed to 100% compound (unoccluded) for 24, 48 or 72 hr. Citronellol was not mutagenic when tested in Salmonella typhimurium strains TA98 and TA100 in the presence and absence of metabolic activation. ECOTOXICITY STUDIES: Golden Orfe (Leuciscus idus) were exposed to this chemical under static conditions for 96 hours. No mortalities were seen in the control and 4.64 mg/L groups. At 10 mg/L, apathy was noted up to 24 hr, but no mortalities were noted at 96 hr. At 21.5, 46.4 and 100 mg/L, 100% mortality was seen 1 hour after exposure.

Citronellol is a monoterpenoid that is oct-6-ene substituted by a hydroxy group at position 1 and methyl groups at positions 3 and 7. It has a role as a plant metabolite.
Citronellol has been reported in Ambrosiozyma monospora, Artemisia princeps, and other organisms with data available.
3,7-Dimethyl-6-octen-1-ol is a metabolite found in or produced by Saccharomyces cerevisiae.

Mechanism of Action
We evaluated the effects of rose oil on the peroxisome proliferator-activated receptor (PPAR) and cyclooxygenase-2 (COX-2).Citronellol and geraniol, the major components of rose oil, activated PPAR alpha and gamma, and suppressed LPS-induced COX-2 expression in cell culture assays, although the PPARgamma-dependent suppression of COX-2 promoter activity was evident only with citronellol, indicating that citronellol and geraniol were the active components of rose oil.
