  • 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.

  • Environmental Bioconcentration: BCF values less than 0.3 to 0.9 and less than 3.9 were measured using orange-red killifish (Oryzias latipes) which were exposed to 1 and 0.1 ppm, respectively, over an 8-week period(1). According to a classification scheme(2), these BCF values suggest 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 3.6(SRC), determined from a log Kow of -1.50(2) and a regression-derived equation(3), indicates that piperazine is expected to have very high mobility in soil(SRC). Measured pKa values of 9.73 (first nitrogen) and 5.33 (second nitrogen)(4) indicate that piperazine will exist primarily in cation form in the environment and cations generally adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(5). Volatilization of piperazine from moist soil surfaces is not expected to be an important fate process(SRC) since cations do not volatilize. Piperazine is not expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 0.16 mm Hg(6). Piperazine may biodegrade in soil based on greater than 51% biodegradation measured after 28 days in a artificial river water total organic carbon (TOC) die-away test; however, only 1.4% degradation occurred after 14 days during a MITI screening test(7,8). Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 3.6(SRC), determined from a log Kow of -1.50(2) and a regression-derived equation(3), indicates that piperazine is not expected to adsorb to suspended solids and sediment(SRC). However, measured pKa values of 9.73 (first nitrogen) and 5.33 (second nitrogen)(4) indicate piperazine will exist almost entirely in the cation form at pH values of 5 to 9 and cations adsorb to suspended solids and sediment more strongly than their neutral counterparts(5). Volatilization of piperazine from water surfaces is not expected to be an important fate process since cations do not volatilize. According to a classification scheme(6), a BCF range of less than 0.3-0.9(7) suggests the potential for bioconcentration in aquatic organisms is low(SRC). Piperazine may biodegrade in water based on greater than 51% biodegradation measured after 28 days in a artificial river water total organic carbon (TOC) die-away test; however, only 1.4% degradation occurred after 14 days during a MITI screening test(7,8). 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), piperazine, which has a vapor pressure of 0.16 mm Hg at 20 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase piperazine 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 2.3 hours(SRC), calculated from its rate constant of 1.7X10-10 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3). Piperazine does not contain chromophores that absorb at wavelengths >290 nm and therefore is not expected to be susceptible to direct photolysis by sunlight(4).

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. Regional annex coverage does not replace member-state implementation dates, notifications or national deviations.

The record cites ASEAN Annex II, reference 1504, source version 2026-1. 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.
