Description of key information
The proportion of test item having an inhalable particle size of less than 100 µm was determined to be 0.1%. The test item was therefore considered to be essentially non-inhalable.
Additional information
The test was performed according to 'Particle Size Distribution, Fibre Length and Diameter Distribution’, June 1996 European Commission technical guidance document, which satisfies the requirements of OECD Guideline 110, 12 May 1981. No deviation from the guideline was observed during the test.
The test item was observed to be a uniform, granular solid. The preliminary screening test indicated the absence of any fine particle fraction within the test item. It was therefore possible to conclude that that the test item was of a particle size distribution that was essentially non-inhalable without the need to complete the cascade impactor assessment.
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.
