Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
From the results of the ready biodegradability test (degradation: 0 % on day 28) and BOD5/COD ratio (BOD5/COD=1.6 %), it can be concluded that the test substance is not readily biodegradable. An inherent biodegradability test according to OECD Guideline 302B is available. The biodegradation of test substance on day 28 was 18 %. Therefore, Reactive Orange 136 was found to be slightly biodegradable over the 28-day exposure period under the test conditions.
The information from biodegradation and hydrolysis tests is sufficient to conclude on the persistence assessment. Thus simulation tests of biodegradation and identification of degradation products were waived.
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.
