Particle size distribution:

The study does not need to be conducted because the substance is marketed or used in a non solid or granular form.

Vapour pressure:

The vapour pressure of test chemical was estimated to be 0.63 Pa at temperature 25°C.

Partition coefficient:

The partition Coefficient n-octanol/water of test chemical was determined by Shake Flask Method. The study was performed at a temperature of 28°C. The log Pow value was determined to be 2.27 at a temperature of 28°C and pH 3.41.
