Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
If release would occur, the primary source of environmental pollution of Acid Brown 355 (ABr355) is represented by industrial waste water and secondly by release during washing of dyed textile, thus the fate and pathways of ABr355 in surface water is of primary concern.
In the aquatic environment, hydrolysis is not expected to be an important removal process for ABr355.
Phototransformation in air/water/soil has not been investigated.
The binding capacity (adsorption) of the ABr355 to solid surfaces is expected to be low.
Given the intended use in aqueous-based treatments, ABr355 is not expected to be released to air and is not expected to distribute to this compartment.
ABr355 was tested for the ready biodegradation potential according to the OECD Guideline 301A, Modified AFNOR Test. Under test conditions, no biodegradation was observed (0 % after 28 days, based on the DOC-removal), thus ABr355 resulted as not readily biodegradable (Huntsman Textile Effects (Germany) GmbH, 1986).
There are no empirical bioaccumulation data available for ABr355, nevertheless the Pow was calculated as 0.04681 (average log Pow: -1.359) (REACH&colours Kft, 2012) and, on the basis of this outcome, it is expected that ABr355 has a low potential for bioaccumulation and/or a low potential to cross biological membranes.
Direct and indirect exposure of sediment and soil to ABr355 is unlikely; since no exposure of the aquatic compartment is foreseen and thus subsequent sediment and/or soil exposure can be excluded.
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.
