Applicant's summary and conclusion

Conclusions:
In accordance with REACH Annex XI, the bioconcentration study (required in section 9.3.2) does not need to be conducted as the substance has a low potential for bioaccumulation because the substance has no log Kow (substance is an inorganic substance or can be considered to behave as an inorganic substance). Also the substance size will hamper passing membranes as the substance consists of particles with sizes ranging from approximately 0.5 to > 0.5 µm. The particles are not soluble in water.
