Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

Dehydrated sample of SBP-1 -Na (produced by adding aqueous NaOH to SBP1)

Although the substance is defined as a solid, it is always produced as an aqueous solution. Therefore Chapter 9 and 10 in the CSA/CSR are based on the aqueous solution rather than the solid.
