Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The test item has a low volatility (3.4E-7 hPa at 20°C) and should therefore not be released into air. It is a surface active substance which is very soluble in water (ca. 132 g/L) and has a low log Kow (0.3). Based on the QSAR prediction by means of the BCFBAF program v3.01, the substance is considered to have a very low potential for bioaccumulation.
The determination of experimental log Koc values (according to OECD 121) describing the adsorption potential of the substance in soil and sewage sludge at pH values 7 and 9 was not possible. An approximation of the log Koc of 5.17 and 5.308 at pH 4 in soil and sewage sludge, respectively, can be provided by estimation. Based on these results – and taking into account the charged moieties within the compound – it can be concluded that Basic Red 18:1 Acetate has a high adsorption potential in soil and sewage sludge. Therefore, a log Koc of 6 will be used as basis for exposure estimation by means of Chesar/EUSES in a worst-case approach.
Basic Red 18:1 Acetate is not considered to be readily biodegradable based on the results of 28-d biodegradation study according to test method EU C.4-E (Determination of the "Ready" Biodegradability - Closed Bottle Test, Version 29.12.1992; 5 % biodegradation observed). According to known substance data, the substance is stable at high temperatures and acidic and neutral pH. Consequently, the substance is considered to be persistent in the environment.
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.
