Description of key information
In accordance with section 9.3.2, column 2 of Annex IX to Regulation (EC) No 1907/2006 (REACH) the study on bioaccumulation in aquatic organisms (preferred species fish) is scientifically not necessary since the substance has a log Kow < 3. Regarding the log Kow, accumulation of the test substance in organisms is not to be expected.
Key value for chemical safety assessment
Additional information
Waiving justification
In accordance with section 9.3.2, column 2 of Annex IX to Regulation (EC) No 1907/2006 (REACH) the study on bioaccumulation in aquatic organisms (preferred species fish) is scientifically not necessary since the substance has a log Kow < 3. In an experimental study the log Kow of the substance was determined to be 0.68 at 25 °C (see IUCLID section 4.7), which is clearly below the indicated threshold value for bioaccumulation potential. Further, based on the structure and physicochemical properties of the substance the potential to cross biological membranes is low. Therefore, the study on bioaccumulation in aquatic organisms is regarded scientifically not necessary and was waived.
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.
