Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The test substance was tested in in CO2 evolution test and showed 32.1% degradation on day 29.
Key value for chemical safety assessment
- Biodegradation in water:
- under test conditions no biodegradation observed
Additional information
DNNSA is a structural analogue of CaDDNSA. Under the conditions of the OECD 301B test, di C8-C10, branched, C9 rich, alkylnaphthalene sulphonic acid (DNNSA) was not readily biodegradable. Degradation of DNNSA was 14-17% after 28 days.In a test for inherent biodegradation, no degradation of DNNSA was observed over the 56-day study period.
These results confirm the conclusion that CaDDNSA is not readily biodegradable.
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).
