Description of key information

Appearance:

Based on available data from peer reviewed publication,the chemical 2-hydroxypropyl octadec-9-enoate was observed to be clear and  yellow coloured liquid in appearance.

Freezing point;

Based on prediction done from CompTox Chemistry Dashboard which uses OPERA (OPEn (quantitative) structure-activity Relationship Application) V1.02 model ,to predict the melting point of chemical 2-hydroxypropyl octadec-9-enoate.

The melting point of chemical 2-hydroxypropyl octadec-9-enoate was estimated to be 19.2 degree C.

Boiling point:

Based on available data from authoritative database,the boiling point of chemical 2-hydroxypropyl octadec-9-enoate was determined to be in the range of 176 degree C to 183 degree C at 2 Torr pressure.

Density:

Based on prediction done using ACD/I-Lab 2.0,the density of chemical 2-hydroxypropyl octadec-9-enoate was estimated to be 0.919 ± 0.06 g/cm3.

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.

2-hydroxypropyl octadec-9-enoate was observed to be clear and  yellow coloured liquid in appearance.Hence, this endpoint was considered for waiver.

Vapor Pressure:

MPBPVP v1.43 was used to estimate the vapor pressure of Propylene Glycol Monooleate. The estimated vapour pressure of Propylene Glycol Monooleate at 25 deg C was 1.22E-06 Pa.

Partition Coefficient:

KOWWIN v1.68 was used to estimate the octanol water partition coefficient of Propylene Glycol Mono oleate. The estimated logPow of Propylene Glycol Mono oleate was 7.46. This value indicates that Propylene Glycol Mono oleate is hydrophobic in nature, which is also supported by its very low solubility in water.

Water Solubility:

WSKOW v1.42 was used to estimate the water solubility of Propylene Glycol Monooleate.The estimated water solubility of Propylene Glycol Monooleate at 25 deg C was 0.009738 mg/l.

This value suggests that Propylene Glycol Monooleateis insoluble in water.

Surface tension:

Based on the data from ACD labs, surface tension for test item 2-hydroxypropyl octadec-9-enoate was predicted to be 33.9 ± 3.0 dyne/cm.

Flash point:

From the available data of flash point of 2-hydroxypropyl octadec-9-enoate (1330-80-9) was determined to be 167 degree C.Based on criteria mentioned in CLP regulation the chemical has flash point >than 60 degree C hence the substance was considered to be non-flammable.

Autoflammability:

2-hydroxypropyl octadec-9-enoate did not catch fire on being exposed to air at room temperature of 27°Cpressure of 966 hPa. This indicates that 2-hydroxypropyl octadec-9-enoate is not auto-flammable.

Flammability:

2-hydroxypropyl octadec-9-enoate 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-hydroxypropyl octadec-9-enoate is not flammable at high temperature. However since such high temperatures are not found under normal circumstances of transportation and use, thus 2-hydroxypropyl octadec-9-enoate 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 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
