Description of key information

The multiconstituent substance is not readily biodegradable but the main constituents hydrolyse fast. The log Pow of the remaining major constituents and proposed degradation products formaldehyde (CAS 50-00-0, logPow 0.35) and tolyltriazole (CAS 29385-43-1, logPow 1.71) is below 3. Based on weights of evidence with QSAR BCF data, it can be concluded that bisethylhexylamine (CAS 106-20-7, logPow 6.56 for the uncharged molecule and logPow 7.3 at pH 7.5) does not significantly accumulate in organisms.
However, the BCF for the main component of the multiconstituent substance was calculated to be approx. 166 (considering biotransformation) - 1680 L/kg ww (without considering metabolism) using EPI Win (BASF SE, 2013).
Secondary poisoning is therefore, highly unlikely to occur in any extent for the test item.
