Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
This end-point study is waived. The justification for the waiving is the adaptation according to column 2 of Annex VIII, 9.3.1 and explained by the physicochemical properties: MMVF note Q fibres are purely inorganic and will not adsorb to soil and sediment. The leached positive charged ions (Na+, K+, Ca2+,Mg2+, Ba2+) may adsorb to both the clay fraction and the organic matter fraction. They are however considered to be natural constituents in both in fresh and marine waters, and in soil pore water and in the soil/sediment matrix.
Key value for chemical safety assessment
Additional information
Based on the physicochemical properties of MMVF note Q fibres: MMVF note Q fibres are purely inorganic and inert and will not adsorb to soil and sediment. The positive charged leached ions (Na+, K+, Ca2+,Mg2+, Ba2+) may adsorb to both the clay fraction and the organic matter fraction. They are however considered to be natural constituents in both in fresh and marine water and in soil pore water and soil/sediment matrix.
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.
