Description of key information

Appearance / physical state / colour:

The appearance of chemical Cinnamyl propionate was observed as colorless to pale yellow colored organic liquid with spicy, fruital, floral odor.

Melting point/ Freezing point:

Based on prediction done from modelling database CompTox Chemistry Dashboard, the freezing point of chemical Cinnamyl propionate

was estimated to be -21.9 °C.

Boiling point:

The boiling point of Cinnamyl propionate was determined as 289 °C.

Density:

The density of Cinnamyl propionate was determined to be 1.029-1.034 g/cm³.

Particle size distribution (Granulometry):

The study does not need to be conducted because the substance Cinnamyl propionate is in non solid form i.e in liquid form.

Vapour pressure:

The estimated vapour pressure of the test substance Cinnamyl propionate at 25 deg C was 0.9826 Pa.

Partition coefficient:

The octanol water partition coefficent ( Pow) of chemical (2E)-3-phenylprop-2-en-1-yl propanoate was estimated to be 3.34 at temparature 25oC.

Water solubility:

The estimated water solubility of substance Cinnamyl propionate at 25 deg C was  69 mg/l.

Surface tension:

The surface tension for chemical Cinnamyl propionate was predicted to be 37.6 ± 3.0 dyne/cm.

Flash point:

The flash point of Cinnamyl propionate was determined as 100 °C.

Autoflammability:

Cinnamyl propionate did not catch fire on being exposed to air at room temperature of 27°C pressure of 966 hPa. This indicates that Cinnamyl propionate is not auto-flammable.

Flammability:

Cinnamyl propionate does not indicate any ignition when the flame of bunsen burner having temperature of approximately 950°C is brought in contact with it. Thus it can be concluded that Cinnamyl propionate is not flammable at high temperature. However since such high temperatures are not found under normal circumstances of transportation and use, thus Cinnamyl propionate was considered non-flammable for chemical safety assessment.

Explosiveness:

The study does not need to be conducted because there are no chemical groups present in the molecule which are associated with explosive properties.

Oxidising properties:

The study does not need to be conducted because there are no chemical groups present in the molecule which are associated with oxidizing properties and hence the classification procedure does not need to be applied.

Additional information

Appearance / physical state / colour:

Based on available data from handbooks, the appearance of chemical Cinnamyl propionate was observed as colorless to pale yellow colored organic liquid with spicy, fruital, floral odor.

Melting point/ Freezing point:

Based on prediction done from CompTox Chemistry Dashboard which uses OPERA (OPEn (quantitative) structure-activity Relationship Application) V1.02 and NICEATM models to predict the freezing point of chemical Cinnamyl propionate.

The freezing point of chemical Cinnamyl propionate was estimated to be -21.9 °C.

Boiling point:

Based on available data from handbooks and review articles, the boiling point of Cinnamyl propionate was determined as 289 °C.

Density:

Based on available data from handbooks and review articles, the density of Cinnamyl propionate was determined to be 1.029-1.034g/cm³.

Particle size distribution (Granulometry):

The study does not need to be conducted because the substance Cinnamyl propionate is in non solid form i.e in liquid form.

Vapour pressure:

Modified Grain method (Mean of Antoine and Modified Grain methods) was used to estimate vapour pressure of the substance Cinnamyl propionate using MPBPVP v1.43 of EPI SUITE.

The estimated vapour pressure of the substance Cinnamyl propionate at 25deg C was 0.9826 Pa.

Partition coefficient:

The octanol water partition coefficent ( Pow) of chemical (2E)-3-phenylprop-2-en-1-yl propanoate was estimated to be 3.34 at temparature 25oC.

Water solubility:

Data from authoritative and modelling databases (EPI suite,WSKOW v1.42) suggested that the estimated water solubility of substance Cinnamyl propionate at 25 deg C was 69 mg/l.

Even though other data from handbooks suggested that Cinnamyl propionate was insoluble in water, based on the estimated value for water solubility, the substance Cinnamyl propionate can be considered to be slightly soluble in water.

Surface tension:

Based on the prediction done by ACD labs Software (v12.1.0.50375), the surface tension for chemical Cinnamyl propionate was predicted to be 37.6 ± 3.0 dyne/cm.

Flash point:

Based on available data from handbooks and Material safety data sheet, the flash point of Cinnamyl propionate was determined as 100 °C.

Autoflammability:

Cinnamyl propionate did not catch fire on being exposed to air at room temperature of 27°C pressure of 966 hPa. This indicates that Cinnamyl propionate is not auto-flammable.

Flammability:

Cinnamyl propionate does not indicate any ignition when the flame of bunsen burner having temperature of approximately 950°C is brought in contact with it. Thus it can be concluded that Cinnamyl propionate is not flammable at high temperature. However since such high temperatures are not found under normal circumstances of transportation and use, thus Cinnamyl propionate was considered non-flammable for chemical safety assessment.
