Additional information

The partition coefficient value of the AP 1300 S has been estimated by means two different tools which predicted very similar values:

KOWWIN v1.68 (September 2010)

logPow = 12.42

ACD/LogP tool

logPow = 11.12

The partition coefficient value reported for the Similar Substance 01 in the ECHA website is: > 7.2

Considering the whole data set, in order to complete the assessment the value predicted by means of KOWWIN v1.68 (September 2010) has been considered (logPow = 12.42)
