Description of key information
5% w/w of NC-4 were smaller than 75 µm.
Additional information
The particle size distribution of NC-4 was determined (Huntingdon Life Sciences, 2011); the determination was conducted according to OECD test guideline 110 and in compliance with GLP. It was determined that 5% (w/w) of NC-4 were smaller than 75 µm. As less than 10% by weight of the test substance were found to pass through a 75 µm seive, no further testing was required.
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.
