Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
DVS005u was determined to be not readily biodegradable according to a study performed in line with GLP and to the standardised guidelines OECD 301 and EU Method C.4-C. The substance was determined to be not inherently biodegradable in an OECD 302C Inherent Biodegradability: Modified MITI Test (II).
Key value for chemical safety assessment
- Biodegradation in water:
- under test conditions no biodegradation observed
Additional information
The key study (Clarke, 2010) was conducted in line with GLP and standardised guidelines with a sufficient level of detail to assess the quality of the study. The ready biodegradability study measured CO2 evolution in activated sludge under aerobic conditions. 20 % degradation was observed over 28 days and so the test material was considered to be not readily biodegradable.
Makido (2011) has been provided as a supporting study. The study was conducted in line with GLP and standardised guidelines with a sufficient level of detail to assess the quality of the study. The BOD was calculated to be 0%, showing that biodegradation did not occur. The transformation products were measured at the end of the study and it was determined that 82% to the test material had hydrolysed, where the mass balance of the transformation products and the residual rate was 99-100%. The test material was again considered not to be readily biodegradable.
Mei (2014) has also been provided as a supporting study. In the OECD 302C Inherent Biodegradability: Modified MITI Test (II) the percentage biodegradation at the end of the test by BOD were 0%. At the end of the test, the abiotic degradation rate of the test substance was 91.7%, so it's of little importance to calculate the primary biodegradation according to the residual content of test substance.
All 3 studies were performed to a good standard and have been assigned a reliability score of 1 using the principles for assessing data quality as set out in Klimisch (1997).
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).
