- Executive summary:
Melting/Freezing Point: 69 ± 3 °C (342 ± 3 K) by a modified pour point method, designed to be compatible with Method A.1 Melting/Freezing Temperature of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 102 of the OECD Guidelines for Testing of Chemicals, 27 July 1995.
Reference
Preliminary Test
The pour point of the preliminary test was less than 80°C (353 K).
Definitive Test
The results of the main test are shown in the following table:
| Observation | Determination 1 | Determination 2 |
| Stationary point (°C) | 66 | 66 |
| Pour point (°C) | 69 | 69 |
Overall pour point result 69 ± 3 °C (342 ±3 K)
Discussion
As the test item was a viscous complex mixture, it was considered that the pour point method was the most appropriate test procedure. Due to the test item being very viscous, a high pour point was expected. Therefore, it was decided to perform the test in reverse where the test item was heated at 3 °C intervals and observed for movement within 5 seconds. The temperature at which movement was first observed was considered the pour point and the observation prior to this as the stationary point.
Description of key information
Melting/Freezing Point: 69 ± 3 °C (342 ± 3 K) by a modified pour point method, designed to be compatible with Method A.1 Melting/Freezing Temperature of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 102 of the OECD Guidelines for Testing of Chemicals, 27 July 1995.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 69 °C
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
