Description of key information

Appearance / physical state / colour:

The appearance of Geranyl phenylacetate was observed as colorless organic liquid compound.

Melting point/ Freezing point:

The Freezing point of Geranyl phenylacetate; CAS No. 102-22-7 was determined, using Freezing Temperature Method . No freezing was observed up to -10.41 °C. Hence, the freezing point was inferred to be less than -10.41°C at 967.4 hPa.

Boiling point:

The mean boiling point of Geranyl phenylacetate (CAS No. 102-22-7) is 256.0°C at 970.0 hPa.

Density:

The mean density of Geranyl phenylacetate (CAS No. 102-22-7) was determined to be 1.0555 g/cm³ at 20 °C and 970.1 hPa.

Particle size distribution (Granulometry):

In accordance with column 2 of Annex VII of the REAcH regulation this end point was considered for waiver since the chemical Geranyl phenylacetate is a liquid and is expected to be marketed or used in a non solid or granular form.

Vapour pressure:

The estimated vapour pressure of the substance Geranyl phenylacetate at 25 deg C was 0.007053 Pa.

Partition coefficient:

The octanol water partition coefficent (log Pow) of chemical (2E)-3,7-dimethylocta-2,6-dien-1-yl 2-phenylacetate (102 -22 -7) was estimated to be 6.18 at temparature 25oC. By this log Pow value chemical (2E)-3,7-dimethylocta-2,6-dien-1-yl 2-phenylacetate is considered as hy drophobic in nature.

Water solubility:

The estimated water solubility of substance Geranyl phenylacetate at 25 deg C was  0.0928 mg/L.

Surface tension:

The surface tension for chemical Geranyl phenylacetate was predicted to be 34.5 ± 3.0 dyne/cm.

Flash point:

The mean flash point of Geranyl phenylacetate (CAS No. 102-22-7) is 101.6°C at 970.0 hPa.

Autoflammability:

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

Flammability:

Geranyl phenylacetate 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 Geranyl phenylacetate is not flammable at high temperature. However since such high temperatures are not found under normal circumstances of transportation and use, thus Geranyl phenylacetate 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.

pH:

The pH of 1% w/v emulsion of the Geranyl phenylacetate (CAS No102-22-7) was 4.51 at 25 °C.

Viscosity:

Kinematic viscosity (experimental) of Geranyl phenylacetate (CAS No. 102-22-7) at 20°C and 40°C is 29.2201 mm²/sec and 21.2420 mm²/s, respectively.

Dynamic viscosity (calculated) of Geranyl phenylacetate (CAS No. 102-22-7) at 20°C and 40°C is 29.2347 mPa.S and 21.2526 mPa.S, respectively.
