Description of key information

The Freezing point of test chemical was determined with Freezing Temperature Method and it was determined to be less than -10.86 °C at 978.9 hPa.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:

-10.86 °C

Additional information

The Freezing point determination of test chemical was done using crushed ice and salt . No freezing was observed up to -10.86°C. ence, the freezing point was inferred to be less than -10.86°C at 978.9 hPa.

Other supporting study,the freezing point of test chemical was determined to be less than -60 degree C.

As the data from lab has K1 reliability and the test was performed using standard method of analysis which has the value of freezing point temperature as <-10.86 degree C thus considered as key study for the chemical safety assessment.
