Justification for type of information:
No determination of the adsorption coefficient was possible by the HPLC estimation method, Method C19 Adsorption Coefficient of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 121 of the OECD Guidelines for Testing of Chemicals, 22 January 2001. This was since the method was invalid for the test item. The method is not valid for quaternary amines which present a cationic species at all pH values. No alternative estimation method was available for the adsorption coefficient of this test item.
