Description of key information

The streams in this category have partition coefficients ranges from log Kow 2.2-6.1.

Key value for chemical safety assessment

Log Kow (Log Pow):
at the temperature of:
20 °C

Additional information

Data at 20°C from GKA competence centre analytics (2008, 2008 & 2009) are available for three of the streams in this category (64742-49-0: log Kow 2.4 - 5.7, 92128-65-9: log Kow 2.2 - 6.1, 68476 -55 -1: log Kow 2.2 - 5.2). These data will be read across to all category members.

The mean of the log Kow values for the category is 5.5 at 20°C and this has been used to complete the 'key value for chemical safety assessment'.
