Conclusions:
The Freezing point determination of Castor oil, ethoxylated (CAS No.61791-12-6) was done using crushed ice + salt . No freezing was observed up to -7.76°C. Hence, the freezing point was inferred to be less than -7.76 °C at hPa.
Executive summary:

The Freezing point determination of Castor oil, ethoxylated (CAS No.61791-12-6) was done using crushed ice + salt . No freezing was observed up to -7.76°C. Hence, the freezing point was inferred to be less than -7.76 °C at hPa.
