Description of key information

Determination of the particle size according to OECD 110 is scientifically not justified, since the method is applicable to insoluble substances only. The water solubility must be below 10 to 6 g/L according to criteria of the testing guideline. Since the substance is soluble in water above 10 g/L, particle size distribution was determined by dry sieving according to ISO 2591 Part 1, where woven wire cloth and perforated metal plate were used. Results are provided in Chapter 4.23.
