Additional information
A determination of the particle size distribution of B331 was conducted (CiToxLAB Hungary, 2017, Study 15/361-386AN). The determination was conducted initially by microscopic inspection (100x and 400x magnification) then by laser diffraction. The laser diffraction analysis was condcuted in accordance with OECD method 110 and ISO13320:2009. The study was conducted in compliance with GLP.
The median particle size was found to be 219.732µm. 6.02% of the sample was found to be less than 10µm.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
