Any other information on results incl. tables
In conclusion it can be stated that the particles of FAT 40'576/A are spherical and they tend to form agglomerates, even after sieving. The measurement of the single particles was not possible only agglomerates were measured. There was only minor fraction with a size below 75 urn in the sieve test. The main agglomerate size was found in the range of 2000 urn to 250 urn. Less than 10 % (mean of two measurements) of the particles/agglomerates were smaller than 250 urn.
Applicant's summary and conclusion
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.
