2,2''-dihydroxy-4,4''-(2-hydroxy-propane-1,3-diyldioxy)dibenzophenone

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 surface tension was not determined as the water solubility was determined to be less than 1 mg/L. Method A5 of Commission Directive 92/69/EEC states substances with a water solubility of less than 1 mg/L need not be tested for surface tension.
