Auto flammability

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

Flammability

Flash point of test substance was determined to be 131.3°C . On the basis of GHS classification criteria, test chemical has flash point > 60°C hence the test chemical was considered to be non flammable.

Explosiveness

In accordance with column 2 of the Annex VII of the REACH regulation, the study does not need to be conducted since there are no chemical groups associated with explosive properties present in the molecule of test chemical . Thus, the chemical is not likely to be explosive and has been considered non-explosive for the purpose of chemical safety assessment.

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

pH

The experimental pH value for 1% aqueous solution of test substance was observed to be 10.78 at 24.6 °C ,inferring its  basic nature

Viscosity

The kinematic viscosity (experimental) at 20⁰C and 40⁰C was determined to be 78.37 mm²/sec and 74.91 mm²/sec, respectively.

The dynamic viscosity (calculated) at 20⁰C and 40⁰C was determined to be 75.24 mPa.S and 71.92 mPa.S. respectively
