Description of key information

The uvcb 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),
diethanolamine (CAS 111-42-2, logPow -2.46 at 25°C, pH 6.8-7.3)
and tolyltriazole (CAS 29385-43-1, logPow 1.08 at 25°C, pH 7-8)
is below 3.
However, the BCF for the main component of the uvcb substance was
calculated to be approx. 0.897- 3.16 L/kg ww (BCF) using EPI Win
BASF SE, 2013). Secondary poisoning is therefore, highly unlikely
to occur in any extent for the test item.
