Description of key information
The test substance can be considered to be inherently biodegradable. The Adsorption Coefficient was found to be greater than 4.3 x 10E5, log10 Koc >5.63, classifying the test item as immobile.
Additional information
In a study performed according to the OECD Guideline 302 C (Inherent Biodegradability: Modified MITI Test (II)). The biodegradation of the test substance after 28 days is 21 %.
Performing a hydrolysis was not technically feasible.
As the hydrolysis test is performed at no greater than 50 % of the saturation level, and methodology is required to be able to detect 10 % of the initial concentration, it was considered that achieving an accurate, robust analytical method to detect concentrations in the range of level approximately 1.8 to 0.18 µg/L was not possible.
The Adsorption Coefficient was found to be greater than 4.3 x 10E5, log10 Koc >5.63, using the HPLC screening method, designed to be compatible with Method C.19 Adsorption Coefficient of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 121 of the OECD Guidelines for Testing of Chemicals, 22 January 2001. The results classify the test item as immobile.
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.
