Description of key information
Two studies exist (company test data and MMAD as reported in an OECD 403 study). The results from an acute inhalation study have been chosen as the key study.
Additional information
The Mean Mass Median Aerodynamic Diameter was reported to be 4.22 μm. The inhalable fraction of the test material, % <4 μm, was 48.3%, which would allow the test material to reach upper and lower regions of the respiratory tract of the rat. In addition, this also means that a fraction of the particles will be respirable (i.e. reaching the alveoli) in humans.
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.
