Description of key information
median particle size D50 (determined using OECD 110; GLP): 264 µm
Additional information
The particle size distribution of the test item 2,4-Diethyl-9H-thioxanthen-9-one was determined by laser light scattering, according to OECD Guideline 110 (and OPPTS 830.7520 and ISO 13320).
A reliability score of 1 was assigned, in accordance with the criteria for assigning data quality in line with the principles described by Klimisch (1997).
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.
