12.1 Toxicity
Benzyl cinnamate's production and use in artificial flavors and perfumes, mainly as a fixative, may result in its release to the environment through various waste streams. If released to air, an estimated vapor pressure of 1X10-5 mm Hg at 25 °C indicates benzyl cinnamate will exist in both the vapor and particulate phases. Vapor phase benzyl cinnamate will be degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals; 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. Particulate-phase benzyl cinnamate will be removed from the atmosphere by wet and dry deposition. If released to soil, benzyl cinnamate is expected to have no mobility based upon an estimated Koc of 10,400. Volatilization from moist soil surfaces is not expected to be an important fate process based upon an estimated Henry's Law constant of 3.3X10-7 atm-cu m/mole. Benzyl cinnamate is not expected to volatilize from dry soil surfaces based upon its vapor pressure. If released into water, benzyl cinnamate is expected to adsorb to suspended solids and sediment based upon its estimated Koc. Volatilization from water surfaces is not expected to be an important fate process based upon this compound's estimated Henry's Law constant. An estimated BCF of 270 suggests the potential for bioconcentration in aquatic organisms is high. A base-catalyzed second-order hydrolysis rate constant of 3.8X10-2 L/mole-s
