Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
ROC-601 was investigated for biodegradability “Determination of the aerobic ready biodegradability of ROC-601 in the CO2 Evolution Test following OECD 301B resp. EU C.4-C”.
The test item ROC-601 was tested using a concentration of nominally 20 mg organic carbon/L (corresponding to 28.9 mg ROC-601/L) in test medium following OECD 301B and EU-Method C.4-C.
Aniline was chosen as positive control. Activated sludge was used as inoculum (concentration in the test 25.0 mg dry matter/L). The test was left running for 28 days.
All validity criteria were met. Degradation of the positive control was 70 % after 9 days.
The following data were determined for the test item ROC-601:
- 10-day-window: day 9 – 19
- degradation at the end of 10-day-window 48 %
- degradation at the end of the test: 76 %
Therefore, when applying the 10-day-window, the test item ROC-601 is not readily biodegradable following OECD 301B/EU C.4-C. As degradation surpassed 60% in the course of the test, ROC-601 is considered as ultimately biodegradable within 28 days.
Additional information
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.
