Description of key information

Appearance:

Based on available data from reliable handbook the chemical 3,7-dimethylocta-2,6-dien-1-yl 2-methylpropanoate was observed to be Colourless to pale yellow coloured liquid having light rose odour.

Freezing point:

Based on the prediction done using the EPI Suite MPVPBP V1.43,the freezing point of chemical 3,7-dimethylocta-2,6-dien-1-yl 2-methylpropanoate was predicted.

The melting point of chemical 3,7-dimethylocta-2,6-dien-1-yl 2-methylpropanoate was estimated to be 4.57 ˚C

Boiling point:

Based on available data from reliable sources such as authoritative database and handbook ,the boiling  point of chemical 3,7-dimethylocta-2,6-dien-1-yl 2-methylpropanoate was determined to be 265 C at 760 mm of Hg.

Density:

Based on available data from reliable sources such as authoritative database and handbook ,the density of chemical 3,7-dimethylocta-2,6-dien-1-yl 2-methylpropanoate was determined to be 0.8897 g/cm3 15 degree C.

Particle Size Distribution:

The study does not need to be conducted because the test chemical is marketed or used in a non- solid or granular form.Geranyl isobutyrate is a colorless to pale yellow liquid in appearance. Hence this endpoint was considered for waiver.

Vapor Pressure:

Data from various modelling databases suggests that the estimated vapor pressure of Geranyl isobutyrate at 25°C was 1.07 Pa

Partition Coefficient:

Data from various databases suggests that the estimated log Pow of Geranyl isobutyrate was 5.38. Based on the value, it can be considered that Geranyl isobutyrate is hydrophobic in nature, which also supported by its low solubility in water. 

Water Solubility:

Data from various databases suggests that the estimated water solubility of Geranyl isobutyrate at 25 deg C was determined as 0.824 mg/l. This value suggests that Geranyl isobutyrate is insoluble in water.

Surface tension:

Based on the data from ACD labs, surface tension for test item 3,7-dimethylocta-2,6-dien-1-yl 2-methylpropanoate was predicted to be 28.4 ± 3.0 dyne/cm.

Flash point

The flash point of 3,7-dimethylocta-2,6-dien-1-yl 2-methylpropanoate (2345 -26 -8) was calculated to be 116.811 degree C. Based on criteria mentioned in CLP regulation the substance 3,7-dimethylocta-2,6-dien-1-yl 2-methylpropanoate(2345 -26 -8) was considered to be non flammable.

Autoflammability:

3,7-dimethylocta-2,6-dien-1-yl 2-methylpropanoate did not catch fire on being exposed to air at room temperature of 27°Cpressure of 966 hPa. This indicates that 3,7-dimethylocta-2,6-dien-1-yl 2-methylpropanoate is not auto-flammable.

Flammability:

3,7-dimethylocta-2,6-dien-1-yl 2-methylpropanoate 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 3,7-dimethylocta-2,6-dien-1-yl 2-methylpropanoate is not flammable at high temperature. However since such high temperatures are not found under normal circumstances of transportation and use, thus 3,7-dimethylocta-2,6-dien-1-yl 2-methylpropanoate was considered non-flammable for chemical safety assessment.

Explosivenes:

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 the organic substance contains oxygen or halogen atoms which are chemically bonded only to carbon or hydrogen and hence, the classification procedure does not need to be applied
