Endpoint:

surface tension

Data waiving:

study technically not feasible

Justification for data waiving:

the study does not need to be conducted because water solubility is below 1 mg/L at 20°C

Justification for type of information:

Not applicable since the substance is not soluble in water.

Description of key information

No data - data waiving.

Additional information

Based on to the chemical structure of the constituents (i.e. long,hydrophobic alkyl-chains), it can be assumed that the test substance has very low water solubility. This is supported by the experimental data on water solubility and partition coefficient of the read-across substances as well as the calculated predictions for each constituent of the test substance by ChemProp and EPI Suite. Based on the provided information, it cannot be reasonably expected that the water solubility of the test substance is greater or equal to 1 mg/L at 20 °C. Therefore, the study is technically not feasible and does not need to be conducted.
