Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Stability
Hydrolysis
A hydrolysis study does not to be conducted because the test substance is highly insoluble in water.
The water solubility is <<1 mg/L.
Biodegradation
Biodegradation in water: screening test
The test substance was determined to be non biodegradable. Based on several screening tests (BOD5, COD, OECD 301E, OECD 302C), the brominated form of the test item and the brominated form of a structural analogue (RA) did not indicate any biodegradability. The target substance is neither considered ready nor inherently biodegradable. The brominated form of the substance is not inhibitory to activated sludge respiration (OECD 209).
Transport and distribution
Adsorption / desorption
The adsorption coefficient log Koc of a structural analogue (RA) was determined to be 3.8 for soil and 4.0 for sewage sludge.
Additional information
Due to the very low water solubility of Disperse Blue 291:1 (Cl) hydrolysis is unlikely to happen. This is a typical property of disperse dyes. Consequently, no hydrolysis study was performed. Available studies from source substances show the dyes to be not readily or inherently biodegradable. The substances share the same kind of organic functionalities (phenyl azo bond) and the same constituents, therefore they are expected to have the same behaviour in environmental conditions. The adsorption coefficient log Koc was determined to be 3.8 for soil and 4.0 for sewage sludge for a structural analogue substance. This means that the substance is expected to mainly adsorb to sewage sludge and will not arrive at the environmental compartments of surface water, sediment or soil.
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.
