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

The substance is concluded not to have surface active properties. Surfactant molecules typically contain both polar (hydrophilic) and non-polar (lipophilic) moieties. In the test substance, both the polar (NH2-group) as well as the non-polar (lipophilic) moiety are considered to be too insignificant to enable amphiphilic properties.

Based on the absence of structural alerts, the test substance is considered not to be a surface active substance and thus the study has been omitted.

Key value for chemical safety assessment
