  • Toxicity Summary: IDENTIFICATION AND USE: 2-Methoxyethanol (2-ME) is a colorless liquid with ether-like odor. It is used as a solvent for cellulose acetate, natural and synthetic resins, some alcohol-soluble dyes; in nail polishes, quick-drying varnishes and enamels, and wood stains. It is also used as a as a jet fuel de-icer. HUMAN EXPOSURE AND TOXICITY: The substance is mildly irritating to the eyes and respiratory tract and may cause effects on the central nervous system, blood, bone marrow, kidneys and liver. Exposure at high levels could cause unconsciousness. The liquid defats the skin. Two non-fatal cases of poisoning by consuming 100 mL 2-ME in men aged 41 and 23 were reported. In addition to agitation and confusion, the predominant clinical features were nausea, cyanosis, hyperventilation, slight tachycardia, and metabolic acidosis. In one patient there were suggestions of moderate kidney failure. No evidence of liver damage was found and both patients recovered within 4 weeks. Chronic poisonings from vapors lead to toxic encephalopathy and evidence of bone marrow depression without hemolysis. Lung, kidney and liver changes have been observed. It was found that individuals exposed in utero Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Bioconcentration: An estimated BCF of 3 was calculated in fish for 2-methyoxyethanol(SRC), using a log Kow of -0.77(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC). Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 1(SRC), determined from a log Kow of -0.77(2) and a regression-derived equation(3), indicates that 2-methoxyethanol is expected to have very high mobility in soil(SRC). Volatilization of 2-methoxyethanol from moist soil surfaces is expected to be an environmental fate process(SRC) given a Henry's Law constant of 3.3X10-7 atm-cu m/mole(4). The potential for volatilization of 2-methoxyethanol from dry soil surfaces may exist(SRC) based upon a vapor pressure of 9.5 mm Hg(5). Utilizing the Japanese MITI test, 83% of the Theoretical BOD was reached in 2 weeks(6) indicating that biodegradation is an important environmental fate process in soil(SRC). Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 1(SRC), determined from a log Kow of -0.77(2) and a regression-derived equation(3), indicates that 2-methoxyethanol is not expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces may occur(4) based upon a Henry's Law constant of 3.3X10-7 atm-cu m/mole(5). Using this Henry's Law constant and an estimation method(3), volatilization half-lives for a model river and model lake are 97 days and 700 days, respectively(SRC). According to a classification scheme(6), an estimated BCF of 3(SRC), from its log Kow(2) and a regression-derived equation(3), suggests the potential for bioconcentration in aquatic organisms is low(SRC). Utilizing the Japanese MITI test, 83% of the Theoretical BOD was reached in 2 weeks(7) indicating that biodegradation is an important environmental fate process in water(SRC). 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), 2-methoxyethanol, which has a vapor pressure of 9.5 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase 2-methoxyethanol 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 31 hours(SRC), calculated from its rate constant of 1.25X10-11 cu cm/molecule-sec at 25 °C(3). 2-Methoxyethanol does not contain chromophores that absorb at wavelengths >290 nm(4) and, therefore, is not expected to be susceptible to direct photolysis by sunlight(SRC).

  • Toxicity Summary: ... The methyl and ethyl ethers of ethylene glycol, ie 2- methoxyethanol (2-ME) esters, 2-methoxyethyl acetate (2-MEA) and 2-ethoxyethyl acetate (2- EEA) ... are all stable, and are all miscible with (or in the case of 2-EEA very soluble in) water and miscible with a large number of organic solvents. ... The solubility of these glycol ethers in water and their relatively low vapor pressure could result in their build-up in water in the absence of degradation. However, degradation by microorganisms in soil, sewage sludge, and water appears to prevent this possibility. Atmospheric emissions resulting from the use of glycol ethers as evaporative solvents result in the greatest environmental exposure.... Effects on Organisms in the Environment: The toxicity of 2-ME and 2-EE to microorganisms and aquatic animals appears to be low. ... The glycol ether acetates (2-MEA and 2-EEA) are far more toxic to fish. The LC50 of 2-EEA for fathead minnows is 46 mg/L and that of 2-MEA for tidewater silverfish and bluegills is 45 mg/L. ... Effects on Experimental Animals and In Vitro Test Systems: Systemic toxicity: The toxicity of 2-ME and 2-EE to experimental animals has been much more widely studie Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Bioconcentration: An estimated BCF of 3.2 was calculated for methyl cellosolve acetate(SRC), using an estimated log Kow of 0.10(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests that bioconcentration in aquatic organisms is low(SRC). Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 30(SRC), determined from an estimated log Kow of 0.10(2) and a regression-derived equation(3), indicates that methyl cellosolve acetate is expected to have very high mobility in soil(SRC). Volatilization of methyl cellosolve acetate from moist soil surfaces is expected to be an important fate process(SRC) given an estimated Henry's Law constant of 1.1X10-6 atm-cu m/mole(SRC) derived from its vapor pressure, 7.0 mm Hg at 20 °C(4), and assigned value for water solubility of 1.0X10+6 mg/L (miscible)(5). The potential for volatilization of methyl cellosolve acetate from dry soil surfaces may exist(SRC) based on its vapor pressure(4). Using aqueous screening tests methyl cellosolve acetate reached 30 to 86.9% of its theoretical BOD over a period of 5 to 14 days(6,7), suggesting that biodegradation may be an important environmental fate process in soil(SRC).

  • Environmental Fate: AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 30(SRC), determined from an estimated log Kow of 0.10(2) and a regression-derived equation(3), indicates that methyl cellosolve acetate 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 1.1X10-6 atm-cu m/mole(SRC) derived from its vapor pressure, 7.0 mm Hg(4), and assigned value for water solubility of 1.0X10+6 mg/L (miscible)(5). Using this Henry's Law constant and an estimation method(3), volatilization half-lives for a model river and model lake are 24 days and 270 days, respectively(SRC). According to a classification scheme(6), an estimated BCF of 3.2(3), from an estimated log Kow(2), and a regression derived equation(7) suggests that bioconcentration in aquatic organisms is low(SRC). Hydrolysis half-lives of 140 and 14 days at pH values of 7 and 8, respectively(10), suggest that hydrolysis is not expected to be an important process except under basic conditions(SRC). Using aqueous screening tests, methyl cellosolve acetate reached 30 to 86.9% of its theoretical BOD over a period of 5 to 14 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), methyl cellosolve acetate, which has a measured vapor pressure of 7.0 mm Hg at 20 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase methyl cellosolve acetate 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 about 1.1 days(SRC) calculated from its rate constant of 9.7X10-12 cu cm/molecule-sec at 25 °C(SRC)that was derived using a structure estimation method(3). Methyl cellosolve acetate does not contain chromophores that absorb at wavelengths >290 nm(4) and therefore is not expected to be susceptible to direct photolysis by sunlight(SRC).
