Melting/Freezing Point. -6 ± 3 °C (267 ± 3 K) by the 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. Conducted under GLP conditions.
Reference
Preliminary Test
The pour point of the preliminary test was -5 ± 3 °C (268 ± 3 K).
Definitive Test
The results of the main test are shown in the following table:
Table 1 - Results
| Observation | Determination 1 | Determination 2 |
| Stationary Point (°C) | -9.0 | -9.0 |
| Pour Point (°C) | -6.0 | -6.0 |
Overall pour point result: 6 ± 3 °C (267 ± 3 K)
Discussion
As the test item was viscous and a complex mixture, it was considered that the pour point method was the most appropriate test procedure.
Description of key information
The pour point of the test item has been determined to be -6 ± 3 °C (267 ± 3 K).
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 267 K
