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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Bioaccumulation: terrestrial

Description of key information
Because of the highly anionic nature of the substance and its instability in aqueous media, terrestrial bioaccumulation is unlikely and testing is not considered necessary.
Key value for chemical safety assessment
Additional information
Thiosulfates are very polar in nature, with a correspondingly very low log Pow. They readily dissociate in aqueous solution or in contact with soil moisture, rendering any quantitatively relevant adsorption onto soils as unlikely. Therefore, bioaccumulation is not of importance and testing is formally not required. Moreover, thiosulfates are chemically unstable in the environment and under physiological conditions in biota, being prone to oxidation processes.
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.
