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 based on structure, surface activity is not expected or cannot be predicted
the study does not need to be conducted because surface activity is not a desired property of the material

Description of key information

In accordance with column 2 of REACH Annex VII, the study does not need to be conducted as based on structure, surface activity of the substance is not expected and not a desired property of the substance.		

Key value for chemical safety assessment

Additional information

Data on surface tension in the range from 22.4 g*s-2 at 172 °C to 38.38 g*s-2 at 20 °C are available for the substance. According to the Guidance on information requirements and chemical safety assessment (R.7a, ECHA, 2014) the surface tension should be determined for a concentration of 1 g/L or 90 % of the water solubility. As the reference does not give any information about that fact, the reliability of the data cannot be assessed.
