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 water solubility is below 1 mg/L at 20°C
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 3-hydroxy-4-{[2-methoxy-5-(phenylcarbamoyl)phenyl]diazenyl}-N-(3-nitrophenyl) -2-naphthamide (Common Name: C.I. Pigment Red 31) is used as coloring agent in paints, Ink and textile industry. For this use, surface activity is not desired property. Hence this study was considered for waiver.
