Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
A single study is available on honey bees by Richards (2006). In this study the 48 h LD0 and LD50 were determined to be 25 ug and > 25 ug active matter per animal, respectively.
There are no further tests availbale on terrestrial toxicity for potassium silicate. However, direct emissions from soluble silicates to the terrestrial compartment are considered negligible. Since silicates are furthermore natural components of soil minerals, such tests would be of limited value. SiO2 makes up 59% of the earth's crust and similar percentages are present in many sediments and soils. The contribution of anthropogenic inputs to the occurrence in the various compartments will be negligible compared to the concentrations contributed to by the natural silica flux.
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.
