Description of key information

Appearance/physical state/colour

2 Phenylpropionaldehyde is a colourless organic liquid with floral odour.

Melting point/freezing point

Freezing point of 2 Phenylpropionaldehyde is reported as <-60°C

Boiling point

The boiling point of 2 Phenylpropionaldehyde is reported to be between 202 - 205°C.

Density

The density /specific gravity of 2 Phenylpropionaldehyde is reported to be 0.998 - 1.006 g/cm³

Particle Size distribution:

The chemical Hydratropaldehyde is a liquid chemical and hence it is technically not possible to estimate the particle size distribution (granulometry) of the chemical. Hence this end point was considered for waiver.

Vapour pressure

The vapour pressure of 2 Phenylpropionaldehyde is reported as 0.4 hPa at 20°C and 12 hPa at 90°C.

Partition coefficient

The octanol-water partition coefficient (log Pow) of 2 Phenylpropionaldehyde is reported as 1.96

Water solubility

2 Phenylpropionaldehyde is reported to be insoluble in water.

Surface Tension:

In accordance with column 2 of Annex VII of the REACH regulation, the study need only be conducted if surface activity is a desired property of the chemical. The chemical Hydratropaldehyde is widely used as a flavor and fragrance chemical. For this use, surface activity is not an important property. Hence this study was considered for waiver.

Flash point

Flash point of 2 Phenylpropionaldehyde is reported as 68.88°C

Auto Flammability:

2 Phenylpropionaldehyde did not catch fire on being exposed to air at room temperature of 27°Cpressure of 966 hPa. This indicates that 2 Phenylpropionaldehyde is not auto-flammable.

Flammability:

2 Phenylpropionaldehyde 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 2 Phenylpropionaldehyde is not flammable at high temperature. However since such high temperatures are not found under normal circumstances of transportation and use, thus 2 Phenylpropionaldehyde was considered non-flammable for chemical safety assessment.

Explosiveness:

In accordance with column 2 of Annex VII of the REACH regulation, the study does not need to be conducted since there are no chemical groups associated with explosive properties present in the molecule of Hydratropaldehyde. Thus, the chemical is most likely to be "Non explosive". Thus, for the purpose of chemical safety assessment, the chemical is considered to be "Non-explosive".

Oxidising Properties:

In accordance with column 2 of Annex VII of the REACH regulation, the substance Hydratropaldehyde is incapable of reacting exothermically with combustible materials on the basis of the chemical structure. It is an organic substance containing oxygen but no halogen atoms and these elements are not chemically bonded to nitrogen or oxygen. Thus, the chemcial is likely to be "Non-oxidising".
