Description of key information
An OECD 301 D Ready Test was conducted on 2 -methyl-p-phenylenediaminesulfate (CAS # 615 -50 -9). Biodegradation was monitored by oxygen consumption.
The biodegradation of the test substance reached 17% on the 28th day. Hence the test material was not readily biodegradable.
Key value for chemical safety assessment
- Biodegradation in water:
- inherently biodegradable
Additional information
An OECD 301 D Ready Test was conducted on 2 -methyl-p-phenylenediaminesulfate (CAS # 615 -50 -9). The test concentration was 6 mg/L, and the inoculum concentration was 10(E4)-10(E6) CFU/L. The test treatment, controls, reference, and blank were conducted in duplicate. Biodegradation was monitored by oxygen consumption.
The biodegradation of the test substance reached 17% on the 28th day.
Hence the test material was not readily biodegradable.
The reference material, sodium acetate, reached >60% after day 6 and met 10 day window. It met the validity criteria established in the guideline for a reference material.
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.
