Description of key information

The measured Log Kow  values for the three main constituents were in the range 5.4 - 6.7

The calculated log Kow for the metabolite of biodegradation i.e. 1-Piperazineethanamine (CAS no 140-31-8) is -1.57. This calculated value is in good agreement with the measured log Kow of piperazine of -1.5 Hansch, C. et al (1995).

Key value for chemical safety assessment

Log Kow (Log Pow):
5.4
at the temperature of:
