Additional information

Proprietary data on the flash point of the streams were available from BASF for the category members, 64742-83-2: -18°C , 92045-23-3: < -30°C, 87741-01-3: < -30°C (BASF 2008). The data from these streams can be read across to the other members of the category. The flash points of the streams were reported to range from <-30°C to -18°C.

The mean of the flash point values for the category is -26°C at 101325 Pa and this has been used to complete the 'key value for chemical safety assessment'.
