Description of key information
Additional information
The likely environmental fate of the substance has been assessed based on the substances physico-chemical properties and relevant study data.
The substance has very low water solubility (the main substance components solubility ranged from 1.42 x 10-5 g/l to 6.92 x 10-5 g/l).
The predicted octanol/water partition coefficient of the main substance components are log10 Pow -2.48, 6.17, 14.4 and 23.1 respectively.
This indicates that any proportion of substance components that are dissolved have potential to partition out of the aquatic environment, bar the substance component with predicted log10 Pow -2.48.
The substances high adsorption coefficient (log10 Koc >5.63) indicates that the substance has potential for adsorption to sediments or soils and is therefore has the potential to partition from the aquatic compartment into the sediment or soil compartments.
The substance is readily biodegradable (82% degradation after 28 days). No hydrolysis study data is available, but based on the biodegradation result the substance is not considered to have the potential to persist in the aquatic environment.
Therefore, despite the predicted octanol/water partition coefficient results and high adsorption coefficient, the low water solubility and ready biodegradation of the substance will limit the amount of substance able to partition from the aquatic environment into soil or sediment compartments. Partitioning and accumulation of the substance in these compartments is therefore not anticipated to be a significant fate.
The predicted octanol/water partition coefficient results indicate that the substance components have some potential for bioaccumulation in aquatic organisms, but predicted BCF values show limited bioaccumulation potential. However, as the substance does not persist in the aquatic environment, bioaccumulation in aquatic organisms is not considered to be a significant fate.
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.
