Description of key information

Appearance / physical state / colour:

The physical appearance of Dioctyl sebacate was observed as, colorless to light yellow organic liquid compound.

Melting point/ Freezing point:

The freezing point of Dioctyl sebacate was determined as 18 deg C.

Boiling point:

The boiling point of Dioctyl sebacate was determined as 218 deg C at 0.5 mmHg pressure.

Density:

The density of Dioctyl sebacate was determined as 0.9074 g/cm3 at 25 deg C.

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 Dioctyl sebacate 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 Dioctyl sebacate at 25 deg C was 0.0000604 Pa.

Partition coefficient:

Octanol water partition coefficient of the 1,10-dioctyl decanedioate (CAS no. 2432-87-3) was estimated. The estimated log POW of the 1,10-dioctyl decanedioate was 10.23. On the basis of estimated value, the 1,10-dioctyl decanedioate can be considered as hydrophobic in nature

Water solubility:

The estimated water solubility of Dioctyl sebacate at 25 deg C was  0.000003856 mg/l.

Surface tension:

The surface tension for chemical Dioctyl sebacate was predicted to be 33.2 ± 3.0 dyne/cm.

Flash point:

The flash point of Dioctyl sebacate was estimated as 198.4 ± 18.2 °C.

Autoflammability:

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

Flammability:

Dioctyl sebacate 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 Dioctyl sebacate is not flammable at high temperature. However since such high temperatures are not found under normal circumstances of transportation and use, thus Dioctyl sebacate 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 handbook, the physical appearance of Dioctyl sebacate was observed as, colorless to light yellow organic liquid compound.

Melting point/ Freezing point:

Based on available data from handbook and authoritative database, the freezing point of Dioctyl sebacate was determined as 18 deg C.

Boiling point:

Based on available data from handbook and authoritative database, the boiling point of Dioctyl sebacate was determined as 218 deg C at 0.5 mmHg pressure.

Density:

Based on available data from handbooks and authoritative database, the density of Dioctyl sebacate was determined as 0.9074 g/cm3 at 25 deg C.

Other supporting studies from ACD/I-Lab 2.0 and Scifinder also supported the selected key value. The density of Dioctyl sebacate was estimated to be 0.918 ± 0.06 g/cm3, at 20 °C and 760 mmHg pressure.

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 Dioctyl sebacate is a liquid and is expected to be marketed or used in a non solid or granular form.

Vapour pressure:

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

The estimated vapour pressure of the Dioctyl sebacate at 25 deg C was 0.0000604 Pa.

Partition coefficient:

Octanol water partition coefficient of the 1,10-dioctyl decanedioate (CAS no. 2432-87-3) was estimated. The estimated log POW of the 1,10-dioctyl decanedioate was 10.23. On the basis of estimated value, the 1,10-dioctyl decanedioate can be considered as hydrophobic in nature

Water solubility:

WSKOW v1.42 was used to estimate the water solubility of the Dioctyl sebacate.

The estimated water solubility of the Dioctyl sebacate at 25 deg C was 0.000003856 mg/l.

Based on the estimated value, the Dioctyl sebacate was considered to be insoluble in water.

Surface tension:

Based on the prediction done by ACD labs Software (v12.1.0.50375), the surface tension for chemical Dioctyl sebacate was predicted to be 33.2 ± 3.0 dyne/cm.

Flash point:

Based on available data from authoritative database Scifinder, the flash point of Dioctyl sebacate was estimated as 198.4 ± 18.2 °C.

Thus accroding to estimated value the given chemical was not classified as flammable.

Autoflammability:

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

Flammability:

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