Description of key information

Appearance:

On the basis of physical appearance, potassium dodecyl sulfate is physically available in white crystalline powder.

Melting point:

Based on the prediction done using the EPI Suite MPVPBP V1.43,the melting point of potassium dodecyl sulfate was predicted.

The melting point of potassium dodecyl sulfate was estimated to be 253.95 ˚C.

Boiling Point:

Based on the prediction done using the EPI Suite MPVPBP V1.43,the Boiling point of potassium dodecyl sulfatewas predicted.

The boiling point of potassium dodecyl sulfate was estimated to be 588.52 ˚C.

Density:

Density of potassium dodecyl sulfate is determined to be 1.065 g/cm3 at 25 Deg C.

Particle size distribution:

The particle size distribution of potassium dodecyl sulfate was determined by granulometric analysis with rotap sieve shaker. The particle size distribution was determined to be in the range of 150 micron to 53 micron.

Vapour pressure:

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

The estimated vapour pressure of potassium dodecyl sulfate at 25 deg C was 6.26E-011 Pa

Partition coefficient:

Based on the available data from modeling database EPI suite using the KOWWIN V1.68 program, the estimated logPOW of the test substancePotassium dodecyl sulfatewas 1.69. Based on this value, chemical Potassium dodecyl sulfate can be considered to be hydrophilic in nature.

Water solubility:

WSKOW v1.42 was used to estimate the water solubility of potassium dodecyl sulfate.

The estimated water solubility of potassium dodecyl sulfate at 25 deg C was 415 mg/l.

Based on the estimated value, potassium dodecyl sulfate was moderately soluble in water

Surface tension:

Surface tension of potassium dodecyl sulfate is determined to be 0.040 N/m.

Flash point:

Flash point of potassium dodecyl sulfate is calculated at 1 atm. Pressure to be 367.88 Deg C.

Auto flammability:

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

Flammability:

Potassium dodecyl sulfate 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 potassium dodecyl sulfate is not flammable at high temperature. However since such high temperatures are not found under normal circumstances of transportation and use, thus potassium dodecyl sulfate 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.

Oxidizing 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.
