  • First Aid: EYES: First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop.; SKIN: IMMEDIATELY flood affected skin with water while removing and isolating all contaminated clothing. Gently wash all affected skin areas thoroughly with soap and water. If symptoms such as redness or irritation develop, IMMEDIATELY call a physician and be prepared to transport the victim to a hospital for treatment.; INHALATION: IMMEDIATELY leave the contaminated area; take deep breaths of fresh air. If symptoms (such as wheezing, coughing, shortness of breath, or burning in the mouth, throat, or chest) develop, call a physician and be prepared to transport the victim to a hospital. Provide proper respiratory protection to rescuers entering an unknown atmosphere. Whenever possible, Self-Contained Breathing Apparatus (SCBA) shou Source: CAMEO Chemicals

  • Toxicity Summary: 2-Phenoxyethanol is a glycol ether. Glycol ethers can produce toxicity following oxidation to the corresponding aldehyde and alkoxyacetic acid by alcohol dehydrogenase (ADH; EC 1.1.1.1) and aldehyde dehydrogenase (ALDH; EC 1.2.1.3), respectively. (A15201) 2-Phenoxyethanol causes reduction of NMDA-induced membrane currents, indicating a neurotoxic potential for 2-phenoxyethanol. (A15202) Source: Toxin and Toxin Target Database (T3DB)
  • Environmental Bioconcentration: An estimated BCF of 1.5 was calculated in fish for 2-phenoxyethanol(SRC), using a log Kow of 1.16(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 15(SRC), determined from a structure estimation method(2), indicates that 2-phenoxyethanol is expected to have very high mobility in soil(SRC). Volatilization of 2-phenoxyethanol from moist soil surfaces is not expected to be an important fate process(SRC) given an estimated Henry's Law constant of 4.9X10-8 atm-cu m/mole(SRC), based upon its vapor pressure, 0.007 mm Hg at 25 °C(3), and water solubility, 2.6X10+4 mg/L(4). One biodegradation study reported theoretical 2-phenoxyethanol BODs of 2% (5-day), 71% (10-day), and 80% (20-day)(3); a theoretical 20-day BOD of 50%(3) indicates biodegrdaation may be an important environmnetal 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 15(SRC), determined from a structure estimation method(2), indicates that 2-phenoxyethanol 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 4.9X10-8 atm-cu m/mole(SRC), derived from its vapor pressure, 0.007 mm Hg at 25 °C(4), and water solubility, 2.6X10+4 mg/L(5). According to a classification scheme(6), an estimated BCF of 1.5(SRC), from its log Kow of 1.16(7) and a regression-derived equation(8), suggests the potential for bioconcentration in aquatic organisms is low. One biodegradation study reported theoretical 2-phenoxyethanol BODs of 2% (5-day), 71% (10-day), and 80% (20-day)(4); a theoretical 20-day BOD of 50% indicates a compound will largely be removed during biological waste treatment(4). 2-Phenoxyethanol is not expected to undergo hydrolysis in the environment due to the lack of functional groups that hydrolyze under environmental conditions(3). 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), 2-phenoxyethanol, which has a estimated vapor pressure of 0.007 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase 2-phenoxyethanol 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 about 11.8 hours(SRC), calculated from its rate constant of 3.27X10-11 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3). Monitoring data have shown that 2-phenoxyethanol can be removed from the atmosphere via precipitation such as snow(4). 2-Phenoxyethanol does not absorb at wavelengths >290 nm(5), and therefore is not expected to be susceptible to direct photolysis by sunlight(SRC).
