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. Disodium [μ-[[7,7'-iminobis[4-hydroxy-3-[[2-hydroxy-5-sulphamoylphenyl]azo]naphthalene-2-sulphonato]](6-)]]dicuprate(2-)  (Cas no. 6798-03-4) is used as a dye. For this use, surface activity is not an important property. Hence this study was considered for waiver.
