  • Environmental Bioconcentration: An estimated BCF of 334 was calculated in fish for myrcene(SRC), using a log Kow of 4.33(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).

  • Environmental Fate: TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 1074(SRC), determined from a structure estimation method(2), indicates that myrcene is expected to have low mobility in soil(SRC). Volatilization of myrcene from moist soil surfaces is expected to be an important fate process(SRC) given an estimated Henry's Law constant of 0.0916 atm-cu m/mole(SRC), derived from its vapor pressure, 2.09 mm Hg(3), and water solubility, 4.09 mg/L(4). However, adsorption to soil may attenuate volatilization(SRC). Myrcene is expected to volatilize from dry soil surfaces(SRC) based upon the vapor pressure of 2.09 mm Hg at 25 °C(3). Myrcene, present at 100 mg/L, reached 82-92% of its theoretical BOD in 2 weeks using an activated sludge inoculum at 30 mg/L and the Japanese MITI test(5) which classifies the compound as readily biodegradable. Monoterpene compounds similar in structure to myrcene (limonene, pinene, terpinene, terpinolene) were readily degraded in aerobic batch experiments using forest soil(6).

  • Environmental Fate: AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 1074(SRC), determined from a structure estimation method(2), indicates that myrcene is 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 0.0916 atm-cu m/mole(SRC), derived from its vapor pressure, 2.09 mm Hg(4), and water solubility, 4.09 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 3.4 hours and 4.6 days, respectively(SRC). According to a classification scheme(6), an estimated BCF of 334(SRC), from its log Kow of 4.33(7) and a regression-derived equation(2), suggests the potential for bioconcentration in aquatic organisms is high(SRC), provided the compound is not metabolized by the organism(SRC). Myrcene is not expected to undergo hydrolysis in the environment due to the lack of functional groups that hydrolyze under environmental conditions(3). Myrcene, present at 100 mg/L, reached 82-92% of its theoretical BOD in 2 weeks using an activated sludge inoculum at 30 mg/L and the Japanese MITI test(8) which classifies Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), myrcene, which has a vapor pressure of 2.09 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase myrcene is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals, ozone and nitrate radicals(SRC); the half-life for the reaction with hydroxyl radicals is estimated to be 1.8 hrs(SRC), calculated from its rate constant of 2.15X10-10 cu cm/molecule-sec at 25 °C(3); the half-life for the reaction with ozone is estimated to be 34 minutes(SRC), calculated from its rate constant of 4.90X10-16 cu cm/molecule-sec(4); the half-life for the reaction with nitrate radicals in nighttime air is estimated to be 4 minutes(SRC), calculated from its rate constant of 1.10X10-11 cu cm/molecule-sec(4). Hydroxyl radical and ozone oxidation of myrcene in the ambient atmosphere yields acetone, formaldehyde and formic acid as degradation products(5). Myrcene does not contain chromophores that absorb at wavelengths >290 nm(6), and therefore is not expected to be susceptible to direct photolysis by sunlight(SRC).

  • Uses: ... Myrcene is the starting material for a range of industrially important products, e.g., geraniol, nerol, linalool, and isophytol. ... Besides its main use as an intermediate for the production of terpene alcohols, myrcene is used in the production of terpene polymers, terpene-phenol resins, and terpene-maleate resins. It can also be used as a solvent or diluting agent for dyes and varnishes. Source: Hazardous Substances Data Bank (HSDB)

  • Uses: Perfume chemicals and flavoring. Myrcene is the major constituent of oil of bay and hop which are used in the manufacture of alcoholic beverages. Myrcene is also present in lemon grass (Cymbopogon citratus), a plant widely used in Brazilian folk medicine. Recently, it was shown that myrcene is a very potent analgesic substance and might be an alternative to the already available analgesic drugs (T39, A2447).
