Administrative data
Link to relevant study record(s)
Description of key information
Key value determined using EU Methods C4-C & C4-E, OECD guidelines 301B & 301D.
Key value for chemical safety assessment
- Biodegradation in water:
- under test conditions no biodegradation observed
Additional information
The biodegradability of the test substance DUSANTOX® 86 was assessed using two different methods:
Method A - Carbon dioxide (CO2) evolution - Modified Sturm test
Method B - Closed bottle test (two-phase closed bottle test)
Based on the results of the biodegradability tests using the method of determination of evolved carbon dioxide(method A)and the closed bottle test (two-phase closed bottle test)(method B), the following biodegradability values were established for the test substance DUSANTOX® 86 after 28 days:
Dt = 29% (method A)
DThOD = 5% (method B)
The test substance DUSANTOX® 86 under the test conditions (method A) and (method B), cannot be considered to be readily biodegradable (D < 60%).
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).
