Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
In a growth inhibition test on Pseudokirchneriella subcapitata according to OECD guideline 201 no effects were observed with a saturated solution of tin sulfide. Therefore, the 72-hr EC50 is > 34 µg a.i./L and the 72-hr NOEC is >= 34 µg a.i./L (equal to soluble fraction from nominal concentration of 100 mg/L).
Calculated for ditin trisulfide the 72-hr EC50 is > 38 µg/L and the 72-hr NOEC is >=38 µg/L (equal to soluble fraction from nominal concentration of 100 mg tin sulfide/L).
The toxicity of tin disulfide on algae (Desmodesmus subspicatus) was tested in a limit test at the limit of water solubility which was determined for algal medium as 11 µg/L (analytical determination during the test) according to OECD guideline 201. No inhibition was observed. Hence, the test item has no effect on the growth of the test organism under the tested conditions.
Based on this information it is considered that also ditin trisulfide has no effect on the growth of the test organism under the tested conditions.

Additional information
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.
