  • Toxicity Summary: IDENTIFICATION AND USE: PROPYLENE CARBONATE is a colorless liquid. Propylene carbonate is used in paints as a high-boiling solvent and film-forming auxiliary, especially in poly(vinyl fluoride) and poly(vinylidene fluoride) systems. It is also employed as an auxiliary in the pigment and dye industry. It is also used In lithium batteries, to decrease sulfur dioxide vapor pressure and increase electrolyte solubility and ionic conductivity. HUMAN EXPOSURE AND TOXICITY: In clinical studies, undiluted propylene carbonate caused moderate skin irritation, whereas 5 and 10% propylene carbonate in aqueous solution produced no skin irritation or sensitization. Cosmetic products or gels containing 0.54-20% propylene carbonate were essentially nonsensitizing and, at most, moderately irritating to human skin. Products formulated with 1.51-20% propylene carbonate were generally nonphototoxic and nonphotosensitizing. However, one product containing 20% propylene carbonate may have produced a low level photoallergic reaction in 1 of 25 subjects tested. ANIMAL STUDIES: The undiluted material was a slight irritant to the skin and a moderate irritant to the rabbit eye. In an acute dermal toxicity stu Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Bioconcentration: An estimated BCF of 3 was calculated in fish for propylene carbonate(SRC), using a log Kow of -0.41(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 5(SRC), determined from a structure estimation method(2), indicates that propylene carbonate is expected to have very high mobility in soil(SRC). Volatilization of propylene carbonate from moist soil surfaces is not expected to be an important fate process(SRC) given an estimated Henry's Law constant of 3.5X10-8 atm-cu m/mole(SRC), based upon its vapor pressure, 0.045 mm Hg(3), and water solubility, 1.75X10+5 mg/L(4). Propylene carbonate is not expected to volatilize from dry soil surfaces(SRC) based upon its vapor pressure(3). A 79% of theoretical BOD using activated sludge in the Japanese MITI test(5) suggests that biodegradation is an important environmental fate process in soil(SRC).

  • Environmental Fate: AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 5(SRC), determined from a structure estimation method(2), indicates that propylene carbonate is not expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is not expected(3) based upon an estimated Henry's Law constant of 3.5X10-8 atm-cu m/mole(SRC), derived from its vapor pressure, 0.045 mm Hg(4), and water solubility, 1.75X10+5 mg/L(5). Propylene carbonate may undergo hydrolysis in the environment due to functional groups that hydrolyze under environmental conditions(3). According to a classification scheme(6), an estimated BCF of 3(SRC), from its log Kow of -0.41(7) and a regression-derived equation(2), suggests the potential for bioconcentration in aquatic organisms is low(SRC). A 79% of theoretical BOD using activated sludge in the Japanese MITI test(8) suggests 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), propylene carbonate, which has a vapor pressure of 0.045 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase propylene carbonate 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 4 days(SRC), calculated from its rate constant of 3.8X10-12 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3). Propylene carbonate contains chromophores that absorb at wavelengths >290 nm(4) and, therefore, may be susceptible to direct photolysis by sunlight(SRC). Source: Hazardous Substances Data Bank (HSDB)
