Description of key information
In accordance wiith Annex XI, 1.2 and 1.5 of REACH Regulation 1907/2006, short- and long-term studies on terrestrial arthropods are scientifically not necessary because of the natural abundance of silica and silicates as minerals in soils.
Key value for chemical safety assessment
Additional information
Lethal and sublethal effects of colloidal silica (containing a biocide) on a terrestrial pollinator, Bombus terrestris (Linnaeus) are reported (Mommaerts et al 2011). Because these effects might have been caused by the biocide contained in the test material, no causal relationship with colloidal silica can be inferred from this study.

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.
