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. tetrasodium 2-[[4-[[4-[(4-amino-6-chloro-1,3,5-triazin-2-yl)amino]-5-sulphonato-1-naphthyl]azo]-7-sulphonato-1-naphthyl]azo]benzene-1,4-disulphonate (CAS no. 70161-16-9) is used as a dye. For this use, surface activity is not an important property. Hence this study was considered for waiver.
