  • 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.

  • Cosmetic Ingredient Review Finding(s): Safe for use in cosmetics, with qualifications Source: Cosmetic Ingredient Review (CIR)
  • Environmental Bioconcentration: An estimated BCF of 5.1 was calculated for p-aminodiphenylamine(SRC), using an estimated log Kow of 1.82(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 3.1X10+3(SRC), determined from a structure estimation method(2), indicates that p-aminodiphenylamine is expected to have slight mobility in soil(SRC). The pKa of p-aminodiphenylamine is 5.20(3), indicating that this compound will partially exist in cation form in the environment and cations generally adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(4). Volatilization of p-aminodiphenylamine from moist soil surfaces is not expected to be an important fate process(SRC) given an estimated Henry's Law constant of 3.7X10-10 atm-cu m/mole(SRC), using a fragment constant estimation method(5). p-Aminodiphenylamine is not expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 1.21X10-5 mm Hg at 25 °C(6). Reported inherent biodegradation values of 28% after 20 days in an adapted activated sludge and 58% after 3 hours in a mixed, non-adapted activated sludge inoculum(7) suggest that biodegradation in the aquatic environment may be an important fate process(SRC). Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 3.1X10+3(SRC), determined from a structure estimation method(2), indicates that p-aminodiphenylamine is 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 3.7X10-10 atm-cu m/mole(SRC), developed using a fragment constant estimation method(4). A pKa of 5.20(5) indicates p-aminodiphenylamine will exist partially in the cation form at pH values of 5 to 9 and therefore volatilization from water surfaces is not expected to be an important fate process(6). According to a classification scheme(7), an estimated BCF of 5.1(SRC), from an estimated log Kow of 1.82(8) and a regression-derived equation(9), suggests the potential for bioconcentration in aquatic organisms is low. Reported inherent biodegradation values of 28% after 20 days in an adapted activated sludge and 58% after 3 hours in a mixed, non-adapted activated sludge inoculum(10) suggest that biodegradation in the aquatic environment may be an important fate process(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), p-aminodiphenylamine, which has a vapor pressure of 1.21X10-5 mm Hg at 25 °C(2), will exist in both the vapor and particulate phases in the ambient atmosphere. Vapor-phase p-aminodiphenylamine 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 1.9 hours(SRC), calculated from its rate constant of 2.0X10-10 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3). Particulate-phase p-aminodiphenylamine may be removed from the air by wet or dry deposition(SRC). p-Aminodiphenylamine contains chromophores that absorb at wavelengths >290 nm(4) and therefore may be susceptible to direct photolysis by sunlight(SRC).
