  • Toxicity Summary: IDENTIFICATION AND USE: Ethylene Glycol Monoethyl ether (EGEE) is a colorless liquid with mild, agreeable odor. It is used as a solvent for nitrocellulose, lacquers and dopes; in varnish removers, cleansing solutions, dye baths; finishing leather with water pigments and dye solutions; increasing stability of emulsions. HUMAN EXPOSURE AND TOXICITY: Short-term exposure: The substance is mildly irritating to the eyes and respiratory tract, may cause effects on the central nervous system, blood, bone marrow, kidneys and liver. Exposure at high levels could cause unconsciousness. Long-term or repeated exposure: The liquid defats the skin, may have effects on the blood and bone marrow. The major long-term effects of exposure for humans are developmental, testicular, and hematological toxicity. A cross-sectional evaluation of semen quality was carried out in workers exposed to EGEE. A control group of workers from the same plant was included. Workers exposed to EGEE had significantly lower average sperm counts than controls, although both groups had lower sperm counts than those found in other occupational groups.

  • Environmental Bioconcentration: An estimated BCF value of 3 was calculated for ethylene glycol monoethyl ether(SRC), using a log Kow of -0.32(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF value 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 2(SRC), determined from a log Kow of -0.32(2) and a regression-derived equation(3), indicates that ethylene glycol monoethyl ether is expected to have very high mobility in soil(SRC). Volatilization of ethylene glycol monoethyl ether from moist soil surfaces is expected to be an important fate process(SRC) given a Henry's Law constant of 4.7X10-7 atm-cu m/mole(4). Ethylene glycol monoethyl ether is expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 5.31 mm Hg at 25 °C(5). Utilizing the Japanese MITI test, 76% 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 2(SRC), determined from a log Kow of -0.32(2) and a regression-derived equation(3), indicates that ethylene glycol monoethyl ether is not expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is expected(4) based upon a Henry's Law constant of 4.7X10-7 atm-cu m/mole(5). Using this Henry's Law constant and an estimation method(4), volatilization half-lives for a model river and model lake are 74 and 540 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, 76% 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), ethylene glycol monoethyl ether, which has a vapor pressure of 5.31 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase ethylene glycol monoethyl ether 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 22 hrs(SRC), calculated from its rate constant of 1.54X10-11 cu cm/molecule-sec at 25 °C(3). Ethylene glycol monoethyl ether 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).

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. ...

  • Environmental Fate: TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 32(SRC), determined from a measured Kow of 0.24(2) and a regression-derived equation(3), indicates that ethylene glycol monoethyl ether acetate will have very high mobility in soil(SRC). Volatilization of ethylene glycol monoethyl ether acetate from moist soil surfaces may be an important fate process(SRC) given its Henry's Law constant of 3.2X10-6 atm-cu m/mole(4). Ethylene glycol monoethyl ether acetate is expected to volatilize from dry soil surfaces(SRC) based on its vapor pressure of 2.00 mm Hg(5). Several screening biodegradation tests have demonstrated that ethylene glycol monoethyl ether acetate is readily biodegradable(6-9); 80% biodegradation was measured for ethylene glycol monoethyl ether acetate in a 20 day screening test(7) suggesting that biodegradation may be an important fate process in soil(SRC).

  • Environmental Fate: AQUATIC FATE: Based on a recommended classification scheme(1), an estimated Koc value of 32(SRC), using a log Kow of 0.24(2) and a regression-derived equation(1), indicates that ethylene glycol monoethyl ether acetate should not adsorb to suspended solids and sediment in water(SRC). Volatilization from water surfaces may occur(1) based on a Henry's Law constant of 3.2X10-11 atm-cu m/mole(3). Using this Henry's Law constant and an estimation method(1), volatilization half-lives for a model river and model lake are 13 and 100 days, respectively(SRC). According to a classification scheme(4),an estimated BCF value of 3.0(SRC), determined from its log Kow(2), suggests that bioconcentration in aquatic organisms is low(SRC). Biodegradation of ethylene glycol monoethyl ether acetate in a 28 day river die-away test resulted in classification as easily degraded(5) and 80% biodegradation occurred in a 20 day screening test(6) which suggest biodegradation as an important environmental fate process in water(SRC). This compound is expected to hydrolyze with estimated half-lives of 305 and 30 days at pH values of 7 and 8, respectively(7). 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), ethylene glycol monoethyl ether acetate, which has a measured vapor pressure of 2.00 mm Hg at 25 °C(2), will exist solely as a vapor in the ambient atmosphere. Vapor-phase ethylene glycol monoethyl ether 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 0.7 days(SRC), calculated from its measured rate constant of 1.3X10-11 cu cm/molecule-sec at 25 °C(3). Ethylene glycol monoethyl ether 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).
