Description of key information

The dissociation constant of FAT 40854/A TE was determined according to OECD 112, EPA OPPTS 830.7370 and GLP.
It was not possible to determine an accurate pKa value of the test substance.
Based on a QSAR for pKa determination on one of the four main components of the test substance, it can be concluded that in environmentally relevant pH, the main components will be fully ionized (based on the structural similarity of the 4 main components, this is deemed applicable to all 4 main components)
