  • 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).
