Conclusions:
The Freezing point of 3-phenylpropyl acetate; CAS No. 122-72-5 was determined using crushed ice + salt. No freezing was observed up to -9.17 °C.
Executive summary:

The Freezing point determination of 3-phenylpropyl acetate (CAS No.122-72-5) was done using crushed ice + salt. No freezing was observed up to -9.17°C. Hence, the freezing point was inferred to be less than -9.17°C at 975.9 hPa.

Description of key information

The Freezing point of 3-phenylpropyl acetate; CAS No. 122-72-5 was determined using crushed ice + salt. No freezing was observed up to -9.17 °C.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
-9.17 °C

Additional information

The Freezing point determination of 3-phenylpropyl acetate (CAS No.122-72-5) was done using crushed ice + salt. No freezing was observed up to -9.17°C. Hence, the freezing point was inferred to be less than -9.17°C at 975.9 hPa.

Other supporting data from reliable handbook, also supported the selected key value and exhibited the freezing point of chemical 3-Phenylpropyl acetate as -40 degree C.
