Applicant's summary and conclusion
- Conclusions:
- Average size of particles: 125.573 μm
D10 = 8.71 μm
D50 = 109.55 μm
D90 = 267.70 μm
The study was performed in accordance with generally accepted scientific standards and described in sufficient detail and therefore reliability of Klimisch 2 has been assigned. - Executive summary:
The particle size distribution of the test substance was investigated by laser diffraction based on Mie Scattering (non-GLP, 2016) and the average size of particles has been determined to be 125.573 µm (D10 = 8.71 µm, D50 = 109.55 µm, D90 = 267.70 µm).
According to the results, the inhalation of particles has to be regarded as less significant:
- ~ 45% are < 100 µm (inhalable fraction)
- ~ 0.1 % are < 10 µm (thoracic fraction)
- ~0.05% are < 4µm (respirable fraction)
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).
