Conclusions:
The Freezing point determination of (±)-menthone (CAS No.1074-95-9) was done using crushed ice and salt. No freezing was observed up to -9.60°C. Hence, the freezing point was inferred to be less than -9.60 °C at 978.1 hPa.
Executive summary:

The Freezing point determination of (±)-menthone (CAS No.1074-95-9) was done using crushed ice and salt. No freezing was observed up to -9.60°C. Hence, the freezing point was inferred to be less than -9.60 °C at 978.1 hPa.

Description of key information

The Freezing point determination of (±)-menthone (CAS No.1074-95-9) was done using crushed ice and salt. No freezing was observed up to -9.60°C. Hence, the freezing point was inferred to be less than -9.60 °C at 978.1 hPa.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
-9.6 °C
