Description of key information
The substance is hydrolytically stable at pH values 4, 7, 8 and 9 with half lifes of > 1 year (pH 4, 7 and 8), and 120 days (pH 9).
The substance was tested for ready biodegradability, inherent biodegradability and enhanced ready biodegradability under OECD 301 and OECD 302 test designs. Based on the results of the tests performed, the substance can not be considered as readily biodegradable, but inherently biodegradable (not fullflling specific criteria). In the key studies for ready and inherent biodegradability, the substance exhibited a significant amount of mineralization, i.e. 49% on average in 28 days in an OECD 301 B study and more than 70% in 10 days in an OECD 302 B study, respectively. Besides, at the end of the incubation period of OECD 301 studies (day 28), the plateau phases were not reached. Results of enhanced biodegradation studies show repeatedly, that more than 60% of the substance was ultimately degraded within 60 days of incubation under OECD 301 test design. Hence, though the substance is not readily biodegradable, it is inherently biodegradable and not considered persistent in the environment based on enhanced biodegradation testing under OECD 301 design.
The log Koc value of the substance (1.93) indicates, that the substance is mobile, i.e. that it does not adsorb to soils or sediments according to FAO mobility classification
The BCF of 9.33 L/kg indicates that the substance is not bioaccumulative and hence bioaccumulation is of no concern.
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.
