Any other information on results incl. tables

quantitative concentration of substance was not granted by ECHA; test was done in saturated solution according to comments

substance is very low soluble, < 0.4 mg/l is result of solubility test; see part 4.8

substance with solubility lower than 1 mg/l is not need to test according to EU A.5 method, but when was result granted by ECHA we fill in
