Results and discussion
Melting / freezing point
- Key result
- Melting / freezing pt.:
- < -14.1 °C
- Atm. press.:
- 982 hPa
Any other information on results incl. tables
During the measurement, the viscosity increased, but without freezing.
The aliquot used for initiation did not crystallise.
At -14.1°C, the substance is almost solid.
Accuracy: +/- 0.5°C
Applicant's summary and conclusion
- Executive summary:
The freezing point of the test substance was determined according to OECD102/EU A1/BS4633 guideline.
No freezing was measured down to -14.1°C.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
