  • 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).
