  • Toxicity Summary: 2-Butoxyethanol is a high production volume glycol ether. It is a colorless liquid that is miscible in water and soluble in most organic solvents. 2-Butoxyethanol is used widely as a solvent in surface coatings, such as spray lacquers, quick dry lacquers, enamels, varnishes, varnish removers and latex paint. Based on limited data, ambient exposures in air are generally in the ug/cu m range. Industrial exposure of the general population to this chemical is most likely from inhalation and dermal absorption during the use of products containing 2-butoxyethanol. Levels of airborne 2-butoxyethanol in occupational settings are typically in the mg/cu m range. The results of in vitro studies indicate that human red blood cells are not as sensitive to the hemolytic effects of 2-butoxyethanol and 2-butoxyacetic acid and also that red blood cells are more sensitive to hemolysis by 2-butoxyacetic acid than to hemolysis by 2-butoxyethanol. 2-Butoxyethanol is readily absorbed following inhalation, oral or dermal exposure. The chemical is metabolized via alcohol and aldehyde dehydrogenases, with the formation of 2-butoxyacetaldehyde and 2-butoxyacetic acid, the principal metabolite, although othe Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Bioconcentration: An estimated BCF of 3 was calculated for ethylene glycol mono-n-butyl ether(SRC), using an estimated log Kow of 0.83(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 8(SRC), determined from a log Kow of 0.83(2), indicates that ethylene glycol mono-n-butyl ether is expected to have very high mobility in soil(SRC). Volatilization of ethylene glycol mono-n-butyl ether from moist soil surfaces is expected to be an important fate process(SRC) given an Henry's Law constant of 1.60X10-6 atm-cu m/mole(3). Ethylene glycol mono-n-butyl ether is expected to volatilize slowly from dry soil surfaces(SRC) based upon a vapor pressure of 0.88 mm Hg(4). Ethylene glycol mono-n-butyl ether reached 96% of its theoretical BOD in 14 days using an activated sludge inoculum(5). Therefore this compound is expected to biodegrade rapidly in the soil environment. Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 8(SRC), determined from a log Kow of 0.83(2), indicates that ethylene glycol mono-n-butyl ether is not expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is expected(3) based upon a Henry's Law constant of 1.6X10-6 atm-cu m/mole(4). Using this Henry's Law constant and an estimation method(3), volatilization half-lives for a model river and model lake are 17 and 185 days, respectively(SRC). According to a classification scheme(5), an estimated BCF of 3, from its log Kow of 0.83(2) and a regression-derived equation(6), suggests the potential for bioconcentration in aquatic organisms is low(SRC). Alcohols and ethers are generally resistant to hydrolysis(7). Ethylene glycol mono-n-butyl ether reached 96% of its Theoretical BOD in 14 days using an activated sludge inoculum(8). Therefore this compound is expected to biodegrade rapidly in the aquatic environment. 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 mono-n-butyl ether, which has a vapor pressure of 0.88 mm Hg at 25 °C(2) is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase ethylene glycol mono-n-butyl 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 15 hours(SRC), calculated from its rate constant of 1.86X10-11 cu cm/molecule-sec at 25 °C(3). Ethylene glycol mono-n-butyl 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).
