Conclusions:
The Freezing point of castor oil,sulfated; CAS No. 8002-33-3 was determined with freezing temperature and it was determine to be less than -12.4 °C at 971.4 hPa.
Executive summary:

The Freezing point determination of castor oil, sulfated (CAS No.8002-33-3) was done using crushed ice and salt. No freezing was observed up to -12.4°C. Hence, the freezing point was inferred to be less than -12.4 °C at 971.4 hPa.

Description of key information
