  • GHS Hazard Statements: Not Classified; Reported as not meeting GHS hazard criteria by 1564 of 1564 companies. For more detailed information, please visit ECHA C&L website. Source: European Chemicals Agency (ECHA)
  • ECHA C&L Notifications Summary: Aggregated GHS information provided per 1564 reports by companies from 1 notifications to the ECHA C&L Inventory.; Reported as not meeting GHS hazard criteria per 1564 of 1564 reports by companies.; There are 0 notifications provided by 0 of 1564 reports by companies with hazard statement code(s).; Information may vary between notifications depending on impurities, additives, and other factors.

  • Environmental Bioconcentration: An estimated BCF of 46 was calculated for 2-phenethyl propionate(SRC), using an estimated log Kow of 3.06(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is moderate(SRC). Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 476(SRC), determined from a structure estimation method(2), indicates that 2-phenethyl propionate is expected to have moderate mobility in soil(SRC). Volatilization of 2-phenethyl propionate from moist soil surfaces is expected to be an important fate process(SRC) given an estimated Henry's Law constant of 2.5X10-5 atm-cu m/mole(SRC), using a fragment constant estimation method(3). 2-Phenethyl propionate is not expected to volatilize from dry soil surfaces(SRC) based upon an estimated vapor pressure of 0.051 mm Hg(SRC), determined from a fragment constant method(4). Biodegradation data for 2-phenethyl propionate were not available(SRC, 2006); however, biodegradation is expected to be an important environmental fate process because of the presence of an easily biodegraded ester functional group(5).

  • Environmental Fate: AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 476(SRC,2006), determined from a structure estimation method(2), indicates that 2-phenethyl propionate is 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 2.5X10-5 atm-cu m/mole(SRC), developed using a fragment constant estimation method(4). Volatilization half-lives for a model river and model lake are 7 and 82 days, respectively(SRC). According to a classification scheme(5), an estimated BCF of 46(SRC), from an estimated log Kow of 3.06(6) and a regression-derived equation(7), suggests the potential for bioconcentration in aquatic organisms is moderate(SRC). Biodegradation data for 2-phenethyl propionate were not available(SRC, 2006); however, biodegradation is expected to be an important environmental fate process because of the presence of an easily biodegraded ester functional group(8). Hydrolysis under alkaline conditions may be an important environmental fate process, given an estimated base-catalyzed hydrolysis half-life of 63 days at pH 8(9).

  • Environmental Fate: ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), 2-phenethyl propionate, which has an estimated vapor pressure of 0.051 mm Hg at 25 °C(SRC), determined from a fragment constant method(2), is expected to exist solely in the vapor-phase in the ambient atmosphere. Vapor-phase 2-phenethyl propionate is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals. The half-life for this reaction in air is estimated as 2 days(SRC), from its rate constant of 8.3X10-12 cu cm/molecule-sec at 25 °C(SRC), derived using a structure estimation method(3).

  • Sources/Uses: Used as an insect attractant of Japanese beetles in orchards; [HSDB] Used as flavoring agent or adjuvant; [ToxPlanet: FDA] Source: Haz-Map, Information on Hazardous Chemicals and Occupational Diseases
  • Uses: For phenethyl propionate (USEPA/OPP Pesticide Code: 102601) ACTIVE products with label matches. /SRP: Registered for use in the U.S. but approved pesticide uses may change periodically and so federal, state and local authorities must be consulted for currently approved uses./ Source: Hazardous Substances Data Bank (HSDB)
  • Uses: ...Used widely for monitoring new infestations of the Japanese beetle Popillia japonica and for removal trapping in orchards. Source: Hazardous Substances Data Bank (HSDB)
