Referenceopen allclose all
Large particles remain in the 300 µm sieve with light caking observed in lower sieves. Therefore the sample is believed to be finer than the test indicates (due to observed blinding/agglomeration effects).
Description of key information
The particle size distribution:
D10 97 µm
D50 176 µm
D90 241 µm
Additional information
The information of particle size distribution is taken from company data (Emery Oleochemicals and Oleon NV).
The main fraction of particles (60.4%) is observed in the range of 150 - 300 µm.
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.
