Additional information

The partition coefficient of the test substance which is a UVCB substance characterized by varying proportions of constituents could not be determined experimentally in an explicit way. Instead, log Pow values for individual constituents were calculated by valid QSAR. The highest value, obtained applying KOWWIN v1.68 (US EPA Episuite v4.1) to monomeric C12 constituent, was selected as worst case. Results of respective calculations for shorter chains and dimeric/trimeric constituents are significantly lower (from -3.52 to 1.92). As the constituents with the chain length > C12 (i.e. C14, C16) do not contribute to the overall composition significantly, the calculation results obtained for them were discarded.
