  • 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 th Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Bioconcentration: An estimated BCF of 177 was calculated in fish for citronellol(SRC), using a log Kow of 3.91(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is high(SRC), provided the compound is not metabolized by the organism(SRC). Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 94(SRC), determined from a structure estimation method(2), indicates that citronellol is expected to have high mobility in soil(SRC). Volatilization of citronellol from moist soil surfaces is expected to be an important fate process(SRC) given an estimated Henry's Law constant of 2.1X10-5 atm-cu m/mole(SRC), derived from its vapor pressure, 0.02 mm Hg(3), and water solubility, 200 mg/L(4). Even though the vapor pressure is low environmentally at standard temperature and pressure, there is a detectable odor; therefore, citronellol may volatilize from dry soil(SRC). An 80-90% of Theoretical BOD using activated sludge in the OECD 301F test(5) suggests that biodegradation is an important environmental fate process in soil(SRC). Citronellol was also classified as readily biodegradable by the results of the OECD 301C test (modified MITI) with 65% degradation in 4 weeks(6) and by a DOC Method F test (100% biodegradation in 15 days)(6). Citronellol absorbs at wavelengths >290 nm(7) and, therefore, may be susceptible to direct photolysis on soil surfaces exposed to sunlight(SRC). Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 94(SRC), determined from a structure estimation method(2), indicates that citronellol is not expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is expected(3) based upon an estimated Henry's Law constant of 2.1X10-5 atm-cu m/mole(SRC), derived from its vapor pressure, 0.02 mm Hg(4), and water solubility, 200 mg/L(5). Using this Henry's Law constant and an estimation method(3), volatilization half-lives for a model river and model lake are 2.4 and 21 days, respectively(SRC). According to a classification scheme(6), an estimated BCF of 177(SRC), from its log Kow of 3.91(7) and a regression-derived equation(2), suggests the potential for bioconcentration in aquatic organisms is high(SRC). An 80-90% of Theoretical BOD using activated sludge in the OECD 301F test(8) suggests that biodegradation is an important environmental fate process in water(SRC). Citronellol was also classified as readily biodegradable by the results of the OECD 301C test (modified MITI) with 65% degradation in 4 weeks(9) and by a DOC Method F test (100% biodegradation in 15 days)(9).

  • Environmental Fate: ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), citronellol, which has a vapor pressure of 0.02 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase citronellol is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals(SRC); the half-life for this reaction in air is estimated to be 2.3 hours(SRC), calculated from its rate constant of 1.70X10-10 cu cm/molecule-sec at 24 deg(3). Citronellol is also degraded in the atmosphere by reaction with ozone and nitrate radicals. The half-life for the reaction with ozone is estimated to be 1.1 hours(SRC), calculated from its rate constant of 2.4X10-16 cu cm/molecule-sec at 24 °C(3). The half-life for the reaction with nitrate radicals is estimated to be 4 minutes(SRC), calculated from its rate constant of 1.21X10-11 cu cm/molecule-sec at 24 °C(4). The nitrate radical (NO3) is the dominant atmospheric oxidant during the night-time in most atmospheric environments(5), therefore, night-time degradation appears to be a major fate process for citronellol(SRC).

  • Uses: Citronellol is one of the components responsible for the insect repellent properties of citronella oil ... Citronellol finds extensive use in floral fragrances and in flavors for citrus and other fruit notes. Its stability makes it particularly useful in fragrances for soaps, detergents, and other household products. Citronellol is also important as an intermediate in the synthesis of a number of other aroma chemicals ... Citronellol is the key feedstock for the synthesis of rose oxide. Source: Hazardous Substances Data Bank (HSDB)
  • Uses: Citronellol is one of the most widely used fragrance materials, particularly for rose notes and for floral compositions in general. As flavor material, citronellol is added for bouquetting purposes to citrus compositions. It is the starting material for numerous citronellyl esters and for hydroxydihydrocitronellol, an intermediate in the production of hydroxydihydrocitronellal.
