< -1.9).

Key value for chemical safety assessment

Log Kow (Log Pow):
-1.9
at the temperature of:
20 °C

Additional information

A study was performed to determine the partition coefficient of the test substance, lipase, according to EEC Method A8 and OECD Method 107.

The study was conducted to comply with the requirements of European Council Directive for 91/414/EEC (Annex II) as amended by European Commission Directive 94/37/EC and amended by Commission Regulation (EU) No. 544/2011 Implementing Regulation (EC) Nov 1107/2009 of the European Parliament and of the Council as regards the data requirements for active substances.

The octanol/water partition coefficient of lipase was found to be < 0.01 (log10 Pow = < -1.9).
