Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The substance is insoluble and hence, its log Kow is expected << 3. Hence, its log Koc is expected << 3, too. For risk assessment considerations, its Koc is set as 1 L/kg (log Koc=0), which classifies the substance as mobile according to FAO classification. The substance is a solid powder. Its mobility of particulate substance depends on the size of the solid particles and hence its sedimentation velocity/behaviour in STPs. The average volume distribution shows that D90 is 6.22 µm, i.e. the texture of clay. D10 is 0.59 µm, i.e., the texture of colloids. Hence, all particles of the substance will be removed from waste water during STP processes, either by sedimentation and/or by flocculation. They will hence not be part of effluents. Groundwater contamination is excluded since particles will be filtered during passage through sediment and/or soil layers. Furthermore the substance occurs as natural mineral in the environment (Berndtit) which makes it impossible to distinguish between artificial and natural substance. Hence, the issue of transport and distribution in environmental compartments surface water, groundwater, soil and sediment is of no concern.
