surface tension
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because based on structure, surface activity is not expected or cannot be predicted

Description of key information

Information on surface tension not relevant for As2O3. In accordance with Annex VII section 7.6 Column 2 of regulation (EC) 1907/2006) this study only needs to be conducted if based on the structure surface activity is expected or can be predicted. This is not the case for diarsenic trioxide, which is a solid. In water it dissolves readily yielding arsenite and arsenate ions, which are not capable of influencing surface tension. Based on these considerations, this study is waived.

Key value for chemical safety assessment
