Surface tension

Administrative data

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

Justification for type of information:

The water solubility of the test substance at a temperature of 25 °C was determined according to the flask method is < 1 mg/L
