Description of key information

- Testing is not applicable due to hydrolysis of the substance.

- The log Pow values of the hydrolysis products are known and given as follows:

log Pow of Bis-(2-ethylhexyl)amine = 7.3 at pH 7.5

log Pow of 1H-1,2,4 -triazole = -0.58

log Pow of Formaldehyde = 0.35

Key value for chemical safety assessment

Log Kow (Log Pow):
5.3
at the temperature of:
0 °C

Additional information

The partition coefficient of test substance could not be determined by experiment as the test substance is hydrolytically unstable refers to the study “Hydrolysis of Test Item", GLP report no. 09.093 from Ciba Inc.,(TAOH),2009. Thus the logPow value of degradation products has been considered and individually generated.

The log Pow of Bis-(2-ethylhexyl)amine with CAS number 106-20-7 has been measured refers to ref. OXEA GmbH, report no AN-ASB 0496, 12 April 2010.

The log Pow values of 1H-1,2,4 -triazole with CAS number 288-88-0 and formaldehyde with CAS number 50-00-0 derive from SRC PhysProp Database. (Experimental data, Ref.: Hansch, C ET AL. 1995)
