Executive summary:

A study was conducted according to OECD TG 102 and EU method A.1. The pour point was determined from the lowest temperature at which movement of the test item was observed in a closed test jar. The determination was performed in duplicate. The pour point of the test item was determined to be 44°C at 1013 hPa.

Description of key information

The pour point of the test item was determined to be 44°C at 1013 hPa.
