Additional information

An experimental determination of the partition coefficient was not possible, since the test item is only stable in an aqueous medium and is not available as pure substance. The partition coefficient of the active ingredient of Mexoryl SBO was estimated using the software KOWWIN. The log Pow was estimated to be 3.2 for the active ingredient.
