Description of key information

The study does not need to be conducted because the substance decomposes rapidly. Three further QSAR calculation with different Oligomer chain length were added. The log Pow was determined to be 19.86, 20.43 and 21.00.

Key value for chemical safety assessment

Log Kow (Log Pow):
19.86
at the temperature of:
20 °C

Additional information

According to column 2 of Annex VII Regulation (EC) No 1907/2006 (REACH), due to the rapid hydrolysis of SIKA HArdener LTJ in water the test cannot be performed and was replaced by calculation method for the determination of log Pow:

The result was determined by QSAR estimation with the programme EPIWIN using KOWWIN v1.68 that is recommended in the REACH Guidance on information requirements and chemical safety assessment (2008), Chapter R.7.1.7.3, Table R.7.1-21. The log Pow was calculated for the Oligomere n=2, 6 and 10 respectively. The log Pow was determined to be 19.86, 20.43 and 21.00.
