Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Data for the physico-chemical properties of tin bis(tetrafluoroborate) are not available as the substance only exists in aqueous solution. Endpoints according to the REACH requirements for physico-chemical testing are based on data waiving due to long time experiences in handling or the consideration that testing is not scientifically justified, since the substance is produced, marketed and used in an aqueous solution (1000 g/L tin bis(tetrafluoroborate)). The submitter of the dossier confirms that the substance is not stable by drying up to a concentration of 100% (w/w). Drying the solution (>64% (w/w) tin bis(tetrafluoroborate) leads to decomposition and e.g. the precipitation of tin fluoride.
