- Environmental Bioconcentration: An estimated BCF of 430 was calculated for 2-ethylhexyl acrylate(SRC), using an estimated log Kow of 4.09(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is high(SRC), provided the compound is not altered biologically or chemically once released into the environment(SRP). Source: Hazardous Substances Data Bank (HSDB)
- Environmental Fate: TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 430(SRC), determined from a structure estimation method(2), indicates that 2-ethylhexyl acrylate is expected to have moderate mobility in soil(SRC). Volatilization of 2-ethylhexyl acrylate from moist soil surfaces is expected to be an important fate process(SRC) given a Henry's Law constant of 0.000432 atm-cu m/mole(SRC), derived from its vapor pressure, 0.178 mm Hg(3) and water solubility, 100 mg/L(4). 2-Ethylhexyl acrylate is not expected to volatilize from dry soil surfaces(SRC) based upon its vapor pressure(3). Biodegradation data in soil were not found; however, 2-ethylhexyl acrylate was found to biodegrade 51 to >90% in biodegradation screening tests(4,5). Source: Hazardous Substances Data Bank (HSDB)
- Environmental Fate: AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 430(SRC), determined from a structure estimation method(2), indicates that 2-ethylhexyl acrylate is expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is expected(3) based upon a Henry's Law constant of 0.000432 atm-cu m/mole(SRC), derived from its vapor pressure, 0.178 mm Hg(4) and water solubility, 100 mg/L(5). Using this Henry's Law constant and an estimation method(3), volatilization half-lives for a model river and model lake are 7 hours and 6 days, respectively(SRC). According to a classification scheme(6), an estimated BCF of 280(SRC), from an estimated log Kow of 4.09(7) and a regression-derived equation(8), suggests the potential for bioconcentration in aquatic organisms is high(SRC), provided the compound is not altered physically or chemically once released into the environment(SRP). No hydrolysis data are available for 2-ethylhexyl acrylate; however, hydrolysis is expected to be an important environmental fate process for 2-ethylhexyl acrylate but only at alkaline pHs(SRC).

- Environmental Fate: ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), 2-ethylhexyl acrylate, which has a vapor pressure of 0.178 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase 2-ethylhexyl acrylate 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 19 hours(SRC), calculated from its rate constant of 2.0X10-11 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3). The rate constant for the vapor-phase reaction of 2-ethylhexyl acrylate with ozone has been estimated as 1.8X10-16 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3). This corresponds to an atmospheric half-life of about 6.5 days at an atmospheric concentration of 7X10+11 ozone molecules per cu cm(4). 2-Ethylhexyl acrylate is not expected to be susceptible to direct photolysis by sunlight, since it does not contain functional groups that are expected to absorb light with wavelengths >290 nm(SRC).
