Applicant's summary and conclusion
- Conclusions:
- Interpretation of results (migrated information): other: The material is practically insoluble in water
Material is practically insoluble in water - Executive summary:
Material is practically insoluble in water. The levels of metallic elements (Fe, Cr, Cr(VI),Pb, Mn,Pb,Ni, Cd, Al) as well as As and SiO2 are below the detection limit in transmission dissolution test. Co could be detected but its concentration was close to the detection limit.
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.
