  • 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. IMMEDIATELY call a hospital or poison control center even if no symptoms (such as redness or irritation) develop. IMMEDIATELY transport the victim to a hospital for treatment after washing the affected areas.; INHALATION: IMMEDIATELY leave the contaminated area; take deep breaths of fresh air. IMMEDIATELY call a physician and be prepared to transport the victim to a hospital even if no symptoms (such as wheezing, coughing, shortness of breath, or burning in the mouth, throat, or chest) develop.

  • Environmental Bioconcentration: BCFs of <4.6 to 10 were measured for p-cresidine(1,2). In a bioconcentration test using orange-red killifish, p-cresidine was listed as a compound which is non accumulative or of low accumulation in aquatic organisms(3). According to a classification scheme(4), these BCF values suggest that bioconcentration in aquatic organisms is low. Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 53(SRC), determined from a log Kow of 1.74(2) and a regression-derived equation(3), indicates that p-cresidine is expected to have high mobility in soil(SRC). However, aromatic amines are expected to bind strongly to humus or organic matter in suspended solids and sediments due to the high reactivity of the aromatic amino group(4,5). Volatilization of p-cresidine from moist soil surfaces is not expected to be an important fate process(SRC) given an estimated Henry's Law constant of 1.2X10-7 atm-cu m/mole(SRC), using a fragment constant estimation method(6). p-Cresidine is not expected to volatilize from dry soil surfaces(SRC) based upon an estimated vapor pressure of 2.5X10-2 mm Hg(SRC), determined from a fragment constant method(7). p-Cresidine reached 0.7% of its theoretical BOD in 2 weeks using the Japanese MITI test(8), suggesting that biodegradation is not a rapid environmental fate process in soils(SRC).

  • Environmental Fate: AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 53(SRC), determined from a log Kow of 1.74(2) and a regression-derived equation(3), indicates that p-cresidine is not expected to adsorb to suspended solids and sediment(SRC). However, aromatic amines are expected to bind strongly to humus or organic matter in suspended solids and sediments due to the high reactivity of the aromatic amino group(4,5). Volatilization from water surfaces may occur slowly(3) based upon an estimated Henry's Law constant of 1.2X10-7 atm-cu m/mole(SRC), developed using a fragment constant estimation method(6). Using this Henry's Law constant and an estimation method(3), volatilization half-lives for a model river and model lake are 23 and 169 days, respectively(SRC). According to a classification scheme(7), a BCF of <4.6(8), suggests bioconcentration in aquatic organisms is low(SRC). p-Cresidine reached 0.7% of its theoretical BOD in 2 weeks using the Japanese MITI test(8), suggesting that biodegradation is not a fast environmental fate process in water(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-cresidine, which has an estimated vapor pressure of 2.5X10-2 mm Hg at 25 °C(SRC), determined from a fragment constant method(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase p-cresidine 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 2 hrs(SRC), calculated from its rate constant of 2.2X10-10 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3).

  • Uses: For p-cresidine (USEPA/OPP Pesticide Code: 042002) there are 0 labels match. /SRP: Not registered for current 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)

Questions this page answers

This official record identifies the substance as prohibited for cosmetic use in the stated market scope. Do not rely on a formulation containing this identity until the cited source, effective date and exact substance match have been verified.

A prohibition entry may contain no separate condition text because the regulatory outcome is the prohibition itself. Korean source wording is canonical and other positive lists/notices may still apply to the formulation.

The record cites 화장품 안전기준 등에 관한 규정, 별표 1, record 1-346, source version 2026-19. Open the official source.

No. CAS helps resolve identity, but jurisdictions can classify the same substance differently and can apply different product scopes, limits, warnings and transition dates.
