Endpoint:
surface tension
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because surface activity is not a desired property of the material
Conclusions:
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. The chemical calcium 4-[(E)-2-(4-chloro-3-sulfonatophenyl)diazen-1-yl]-3-hydroxynaphthalene -2-carboxylate (CAS no. 7538-59-2) is used as a coloring pigment dye in ink, etc. For this use, surface activity is not an important property. Hence this study was considered for waiver.
