  • Toxicity Summary: Cinnamaldehyde is an allergen. The physiologic effect of cinnamaldehyde is by means of increased histamine release and cell-mediated immunity. Source: Toxin and Toxin Target Database (T3DB)
  • Environmental Bioconcentration: An estimated BCF of 8 was calculated in fish for cinnamaldehyde(SRC), using a log Kow of 1.9(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 37(SRC), determined from a log Kow of 1.9(2) and a regression-derived equation(3), indicates that cinnamaldehyde is expected to have very high mobility in soil(SRC). Volatilization of cinnamaldehyde from moist soil surfaces may be an important fate process(SRC) given an estimated Henry's Law constant of 3.5X10-6 atm-cu m/mole(SRC), derived from its vapor pressure, 2.89X10-2 mm Hg(4), and water solubility, 1,420 mg/L(5). Cinnamaldehyde is not expected to volatilize from dry soil surfaces(SRC) based upon its vapor pressure(4). Biodegradation data were not available(SRC, 2009). Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 37(SRC), determined from a log Kow of 1.9(2) and a regression-derived equation(3), indicates that cinnamaldehyde is not 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 3.5X10-6 atm-cu m/mole(SRC), derived from its vapor pressure, 2.89X10-2 mm Hg(4), and water solubility, 1,420 mg/L(5). Using this Henry's Law constant and an estimation method(3), volatilization half-lives for a model river and model lake are 290 hours and 91 days, respectively(SRC). According to a classification scheme(6), an estimated BCF of 8(SRC), from its log Kow (2) and a regression-derived equation(7), suggests the potential for bioconcentration in aquatic organisms is low(SRC). Biodegradation data were not available(SRC, 2009). 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), cinnamaldehyde, which has a vapor pressure of 2.89X10-2 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase cinnamaldehyde 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 10 hours and 9.5 hours for the cis- and trans-isomers, respectively(SRC), calculated from its rate constant of 3.8X10-11 and 4.0X10-11 cu cm/molecule-sec at 25 °C for cis- and trans-isomers, respectively(SRC). Cinnamaldehyde does not contain chromophores that absorb at wavelengths >290 nm(4) and therefore is not expected to be susceptible to direct photolysis by sunlight(SRC).

Verification workflow and record completeness

Before using this result in a compliance decision

  1. Confirm that “Cinnamal (2-propenal, 3-phenyl-)” and every CAS/EC identifier refer to the material in your supplier specification.
  2. Search exact identity across Schedules 4–8.
  3. Apply use, concentration and warning conditions.
  4. Check hazardous-substance classification and Group Standard scope.
  5. Confirm the latest legal instrument, not only the spreadsheet.
  6. Document the source version and recheck the regulator before manufacture, notification or market placement.

Questions this page answers

This substance is not unrestricted: cosmetic use is subject to the conditions in the cited official record. Check product type, body area, concentration, purity and warning requirements before deciding whether a formulation is compliant.

If this row does not reproduce conditions, open the cited official detail because omission does not mean unrestricted use. The searchable spreadsheet is an aid; the legal Group Standard and incorporated notices remain authoritative.

The record cites Schedule 5, reference 76, source row 104, source version effective-2026-01-01. 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.
