  • Toxicity Summary: IDENTIFICATION AND USE: Ethyl Butyrate is a colorless liquid. It is used in manufacturing artificial rum; perfumery; the alcoholic solution constitutes the so-called "pineapple oil". It is also used in flavoring extracts, solvent mixture for cellulose esters and ethers. HUMAN EXPOSURE AND TOXICITY: Tested at 5% in petrolatum, ethyl butyrate produced no irritation after a 48 hr closed-patch test in 25 human subjects. ANIMAL STUDIES: Ethyl butyrate applied full strength to intact or abraded rabbit skin for 24 hr under occlusion was moderately irritating. In rabbits admin of 2.14 mL/kg caused increase in respiratory volume. In vitro it has been shown to have a hemolytic effect slightly greater than that of methyl butyrate.

  • Environmental Bioconcentration: An estimated BCF of 8 was calculated in fish for ethyl n-butyrate(SRC), using an estimated log Kow of 1.85(1) and a regression-derived equation(1). According to a classification scheme(2), 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 20(SRC), determined from a structure estimation method(2), indicates that ethyl nbutyrate is expected to have very high mobility in soil(SRC). Volatilization of ethyl n-butyrate from moist soil surfaces is expected to be an important fate process(SRC) given an estimated Henry's Law constant of 4.4X10-4 atm-cu m/mole(SRC), based upon its vapor pressure, 14.0 mm Hg(3), and water solubility, 4,900 mg/L(4). Ethyl n-butyrate is expected to volatilize from dry soil surfaces(SRC) based upon its vapor pressure(3). Ethyl n-butyrate has been classified as readily biodegradable as estimated by results from analogous compounds in the Japanese MITI test(5), suggesting that biodegradation may be 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 20(SRC), determined from a structure estimation method(2), indicates that ethyl n-butyrate 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 4.4X10-4 atm-cu m/mole(SRC), derived from its vapor pressure, 14.0 mm Hg(4), and water solubility, 4,900 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 5 hrs and 5 days, respectively(SRC). According to a classification scheme(6), an estimated BCF of 8(SRC), from an estimated log Kow of 1.85(2) and a regression-derived equation(2), suggests the potential for bioconcentration in aquatic organisms is low(SRC). Ethyl n-butyrate has been classified as readily biodegradable as estimated by results from analogous compounds in the Japanese MITI test(7), suggesting that biodegradation may be 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), ethyl n-butyrate, which has a vapor pressure of 14 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase ethyl n-butyrate 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 3 days(SRC), calculated from its rate constant of 4.94X10-12 cu cm/molecule-sec at 25 °C(3). Ethyl n-butyrate 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).
