- Executive summary:
Melting/Freezing Temperature.The freezing temperature of the test item has been determined to be less than -20 °C (253 K), by the liquid bath method, using a procedure designed to be compatible with Method A1 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
Both samples did not freeze under the conditions of the test, going as low as – 20°C.
Freezing temperature <-20 °C (253 K).
Description of key information
The freezing temperature is less than -20 °C (253 K).
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- -20 °C
