Description of key information

In accordance with column 2 of Annex VII of the REACH regulation, the study need only be conducted if surface activity is a desired property of the chemical. hexasodium 4,4'-{ethene-1,2 -diylbis[(3 -sulfonato-4,1 -phenylene)imino(6 -chloro-1,3,5 -triazine-4,2 -diyl)imino]}bis{6 -[(5 -carbamoyl-1 -ethyl-2 -hydroxy-4 -methyl-6 -oxo-1,6 -dihydropyridin-3 -yl)diazenyl]benzene-1,3 -disulfonate} (68991 -98 -0) is used as a dyes. For this use, surface activity is not an important property. Hence this study was considered for waiver.
