Description of key information
Too few particles were of a size less than 10.0 µm to allow accurate assessment of the mass median aerodynamic diameter.
Additional information
Particle size data was acquired using a procedure designed to be compatible with the European Commission Technical Guidance Document EUR 20268 'Determination of Particle Size Distribution, Fibre Length and Diameter Distribution of Chemical Substances' (2002). The results are as follows:
Measurement |
Method |
Result |
Proportion of test item having an inhalable particle size <100 µm |
Sieve |
14.8% |
Proportion of test item having a thoracic particle size <10.0 µm |
Cascade Impactor |
0.736% |
Proportion of test item having a respirable particle size <5.5 µm |
Cascade Impactor |
0.185% |
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.

This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
