  • First Aid: Warning: Cyclohexylamine is an alkaline-corrosive agent. Contact with eyes may result in severe damage to the cornea, conjunctiva, and blood vessels. Caution is advised.; Signs and Symptoms of Cyclohexylamine Exposure: Acute exposure to cyclohexylamine may result in irritation and burning of the skin, eyes, and mucous membranes. Light-headedness, drowsiness, slurred speech, pupillary dilation, increased salivation, dysphagia (difficulty swallowing), abdominal pain, and spontaneous vomiting may occur. Stridor (high-pitched, noisy respirations), dyspnea (shortness of breath), and pulmonary edema are also common. Apathy and mental confusion may develop, with progression to coma and death.; Emergency Life-Support Procedures: Acute exposure to cyclohexylamine exposure may require decontamination and life support for the victims. Emergency personnel should wear protective clothing appropriate to the type and degree of contamination. Air-purifying or supplied-air respiratory equipment should also be worn, as necessary. Rescue vehicles should carry supplies such as plastic sheeting and disposable plastic bags to assist in preventing spread of contamination.; Inhalation Exposure:; 1. Move v Source: CAMEO Chemicals

  • Environmental Bioconcentration: An estimated BCF of 3 was calculated for cyclohexylamine(SRC), using a log Kow of 1.49(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 150(SRC), determined from a measured log Kow of 1.49(2) and a regression-derived equation(3), indicates that cyclohexylamine as the free base is expected to have high mobility in soil(SRC). A pKa value of 10.6(4) indicates that the protonated form of cyclohexylamine will be the dominant species in moist soil surfaces and cations generally adsorb more strongly to soils than their neutral counterparts. Volatilization of cyclohexylamine from moist soil surfaces is not an important fate process since the cation will not volatilize. The potential for volatilization of cyclohexylamine from dry soil surfaces may exist(SRC) based upon a vapor pressure of 10.1 mm Hg(5). Biodegradation is expected to occur in soils based on standard biodegradability tests conducted with activated sludge and sewage inocula(6-8). Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 150(SRC), determined from a measured log Kow of 1.49(2) and a regression-derived equation(3), indicates that cyclohexylamine as the free base is not expected to adsorb to suspended solids and sediment(SRC). A pKa value of 10.6(4) indicates that the protonated form of cyclohexylamine will be the predominant species in water and cations generally adsorb more strongly than their neutral counterparts. Volatilization from water surfaces is not an important fate process(SRC) since the protonated form will not volatilize. According to a classification scheme(5), an estimated BCF of 3(SRC), from its log Kow of 1.49(2) and a regression-derived equation(6), suggests the potential for bioconcentration in aquatic organisms is low. Biodegradation is expected to occur in aquatic environments based on standard biodegradability tests conducted with activated sludge and sewage inocula(7-9). 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), cyclohexylamine, which has a vapor pressure of 10.1 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase cyclohexylamine 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 7 hours(SRC), calculated from its rate constant of 5.5X10-11 cu cm/molecule-sec at 25 °C(SRC) determined using a structure estimation method(3).

  2. Check prohibited/restricted and positive lists in the current Safety and Technical Standards.
  3. Review technical purpose, use history and any monitoring period.
  4. Confirm Chinese labelling, safety assessment and filing/registration duties.

Official market sources

Verification workflow and record completeness

Before using this result in a compliance decision

  1. Confirm that “环己胺 — Cyclohexylamine （CAS No. 108-91-8）” and every CAS/EC identifier refer to the material in your supplier specification.
  2. Search the current NMPA IECIC List I and List II by Chinese name and identity.
  3. Check prohibited/restricted and positive lists in the current Safety and Technical Standards.
  4. Review technical purpose, use history and any monitoring period.
  5. Confirm Chinese labelling, safety assessment and filing/registration duties.
  6. Document the source version and recheck the regulator before manufacture, notification or market placement.

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. IECIC listing is not blanket approval; absence may require the new cosmetic ingredient route, and restrictions are checked separately.

The record cites NMPA 2021 Catalogue of Raw Materials Banned for Cosmetics, entry 1270, source version NMPA Announcement No. 74 of 2021, effective 2021-05-26. 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.
