Description of key information
Additional information
Adsorption / desorption behaviour
Based on long-term experiences made in the paper dyeing process as well as in actually operating paper mill WTPs, the high adsorption capacity of cationic azo paper dyes has been proven. Therefore the conduct of a laboratory-based adsorption/desorption study is being waived based on scientific grounds. For the substance registered an indicative log Koc value of 6 shall be used for risk assessment.
Henry's Law constant
Thesubstance registeredhas a very low vapour pressure and very good water solubility. The Henry's Law constant will be very low. The substance will not volatilise from water surfaces in significant amounts.
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.
