  • Toxicity Summary: IDENTIFICATION AND USE: 1-Methoxy-2-propyl acetate is used as a solvent in cosmetic formulations, as well as in surface coatings, inks, and cleaners. HUMAN STUDIES: The substance defats the skin, which may cause dryness or cracking. It is irritating to the eyes and respiratory tract. Exposure at high levels could cause depression of the central nervous system. ANIMAL STUDIES: Watery eyes, anorexia, rapid shallow breathing, and excess salivation were observed in rats given a single dose of 4000, 6300, or 10,000 mg/kg 1-methoxy-2-propyl acetate. 1-Methoxy-2-propyl acetate was not a skin irritant in rabbits. 10% 1-methoxy-2-propyl acetate in water was not a sensitizer in a guinea pig maximization test. Some slight changes were observed in the appearance of renal tissues in rats exposed to 3000 ppm 1-methoxy-2-propyl acetate. Slight to moderate degeneration of the olfactory epithelium in the nasal cavities was seen in rats and in mice. 1-Methoxy-2-propyl acetate had no adverse effect on reproductive parameters in rat developmental studies. 1-Methoxy-2-propyl acetate did not induce mutations or toxicity in Salmonella typhimurium strains TA98, TA100, TA1535, or TA1537 or in Escherichia c Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Bioconcentration: An estimated BCF of 3 was calculated in fish for 1-methoxy-2-propyl acetate(SRC), using a log Kow of 0.56(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), a measured log Koc of 0.362, corresponding to a Koc of 2.3(2) indicates that 1-methoxy-2-propyl acetate is expected to have very high mobility in soil(SRC). Volatilization of 1-methoxy-2-propyl acetate from moist soil surfaces is expected to be an important fate process(SRC) given an estimated Henry's Law constant of 3.4X10-6 atm-cu m/mole(SRC), based upon its vapor pressure, 3.92 mm Hg(3), and water solubility, 1.98X10+5 mg/L(2). 1-Methoxy-2-propyl acetate is expected to volatilize from dry soil surfaces(SRC) based upon its vapor pressure(2). 50% Biodegradation in less than one day using sandy and sandy loam soils(4) suggests 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), a measured log Koc of 0.362, corresponding to a Koc of 2.3(2) indicates that 1-methoxy-2-propyl acetate 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 3.4X10-6 atm-cu m/mole(SRC), derived from its vapor pressure, 3.92 mm Hg(4), and water solubility, 1.2X10+5 mg/L(2). Using this Henry's Law constant and an estimation method(3), volatilization half-lives for a model river and model lake are 12 and 93 days, respectively(SRC). According to a classification scheme(5), an estimated BCF of 3(SRC), from its log Kow of 0.56(2) and a regression-derived equation(6), suggests the potential for bioconcentration in aquatic organisms is low(SRC). 100% Biodegadation in the Zahn-Wellens test(7) indicates that biodegradation is an important environmental fate process in water(SRC).

  • Environmental Fate: ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), 1-methoxy-2-propyl acetate, which has a vapor pressure of 3.92 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase 1-methoxy-2-propyl 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 32 hrs(SRC), calculated from its rate constant of 1.2X10-11 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3). d(1); this corresponds to half-lives of 2.4 yrs and 88 days at pH values of 7 and 8, respectively(1). Using an atmospheric simulation chamber, no photolysis of 1-methoxy-2-propyl acetate was observed(4); therefore, the compound is not expected to be susceptible to direct photolysis by sunlight(SRC).
