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.
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
