  • ECHA C&L Notifications Summary: Aggregated GHS information provided per 1794 reports by companies from 13 notifications to the ECHA C&L Inventory. Each notification may be associated with multiple companies.; Information may vary between notifications depending on impurities, additives, and other factors. The percentage value in parenthesis indicates the notified classification ratio from companies that provide hazard codes. Only hazard codes with percentage values above 10% are shown. For more detailed information, please visit ECHA C&L website. Source: European Chemicals Agency (ECHA)
  • Environmental Bioconcentration: An estimated BCF of 270 was calculated for benzyl cinnamate(SRC), using an estimated log Kow of 4.1(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is high(SRC). Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 10,400(SRC), determined from a structure estimation method(2), indicates that benzyl cinnamate is expected to be immobile in soil(SRC). Volatilization of benzyl cinnamate from moist soil surfaces is not expected to be an important fate process(SRC) given an estimated Henry's Law constant of 3.3X10-7 atm-cu m/mole(SRC), using a fragment constant estimation method(3). Benzyl cinnamate is not expected to volatilize from dry soil surfaces(SRC) based upon an estimated vapor pressure of 1X10-5 mm Hg(4). Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 10,390(SRC), determined from a structure estimation method(2), indicates that benzyl cinnamate 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 3.3X10-7 atm-cu m/mole(SRC), developed using a fragment constant estimation method(4). A base-catalyzed second-order hydrolysis rate constant of 3.8X10-2 L/mole-sec(SRC) was estimated using a structure estimation method(5); this corresponds to half-lives of 6 years and 211 days at pH values of 7 and 8, respectively(5). According to a classification scheme(6), an estimated BCF of 269(SRC), from an estimated log Kow of 4.06(7) and a regression derived equation(8), suggests the potential for bioconcentration in aquatic organisms is high(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), benzyl cinnamate, which has an estimated vapor pressure of 1X10-5 mm Hg at 25 °C(2), will exist in both the vapor and particulate phases in the ambient atmosphere. Vapor-phase benzyl cinnamate 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 14 hours for the cis-isomer and 13 hours for the trans-isomer of benzyl cinnamate(SRC), calculated from their rate constants of 28X10-12 and 31X10-12 cu cm/molecule-sec at 25 °C, respectively(SRC), determined using a structure estimation method(3). Particulate-phase benzyl cinnamate may be removed from the air by wet and dry deposition(SRC). Source: Hazardous Substances Data Bank (HSDB)

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 standards are separate controlled publications; absence from a locally indexed excerpt is not permission.

The record cites IS 4707 (Part 2):2025 Annex B, entry 78, source version IS 4707 (Part 2):2025, fifth revision. 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.
