Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Adsorption to solid soil phase is expected.
Key value for chemical safety assessment
Additional information
Two adsorption studies for the assessment of the adsorption potential of the substances in the category of derivatives of 4,4’-bis(1,3,5-triazinyl-2-yl)amino)stilbene-2,2’-disulfonic acid, each with one anilino and one alkyl amino moiety,are available.All studies demonstrate that the substances belonging to this category possess adsorption potential which indicates that the tested substances bind to soils.
EC 432-690-8:
In a study on adsorption/desorption in soil according to OECD Guideline 106 (Adsorption - Desorption Using a Batch Equilibrium Method) the adsorption coefficient Koc was determined as 5580 (log Koc: 3.75).The results of the adsorption/desorption study indicate that the test material is tightly bound to soil components, if exposure should occur.
EC 476-900-6:
In a study on adsorption/desorption in soil according to OECD Guideline 106 (Adsorption - Desorption Using a Batch Equilibrium Method) the adsorption coefficient Koc was determined as < 18 (log Koc: < 1.25). This value indicates that the test substance will not be strongly adsorbed by organic carbon in 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.
