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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
In accordance with EC 1907/2006, Annex IX, point 9.2.1.3, column 2, soil simulation testing is not required since the substance is readily biodegradable, as shown in study section 4.1.2.1.2 and since (2) the substance is not considered highly adsorptive to soil (Koc 759.6 L/kg).
Key value for chemical safety assessment
Additional information
One study is available, which investigated the anaerobic degradation of Docusate Sodium to methane during a digestion tower simulation test, with the purpose to assess whether use of digested sludge in agriculture poses a risk for the soil environment (Cognis, Bendt 2007). The study however demonstrates that Docusate Sodium is biodegradable under anaerobic conditions, since 77% were digested within 21 days, after the sludge had been adapted. The adaptation period duration was four weeks.
These results are used as a read-across to the substance registered, which is the corresponding potassium salt of the substance.
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.
