Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Experimental investigations considering possible toxic effects of '1,3,4-Thiadiazolidine-2,5-dithione, reaction products with hydrogen peroxide and tert-dodecanethiol' towards terrestrial organisms are waived. A reliable Koc of > 4.27 x 10E5 (OECD 121) is available for the closely related substance '1,3,4-Thiadiazolidine-2,5-dithione, reaction products with hydrogen peroxide and tert-nonanethiol' (CAS 91648-65-6) and the required PNECsoil was derived using the Equilibrium Partitioning Method (EPM) described in ECHA Guidance R.10 (Guidance of Information Requirements and Chemical Safety Assessment, Chapter R.10: Characterisation of dose-response for environment, therein chapter R.10.6.1, 2008). It is considered justified that the information available is sufficient and further testing is not required; if necessary, data available from aquatic toxicity testing can be used as a worst case scenario if further characterisation of the terrestrial compartment is desired.
Finally, it is concluded that the UVCB substance '1,3,4-Thiadiazolidine-2,5-dithione, reaction products with hydrogen peroxide and tert-dodecanethiol' does not exhibit relevant ecotoxicity potential in soil organisms.
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.
