Description of key information
The substance is not readily biodegradable, OECD 301B, EU Method C.4 -C, EPA OPPTS 835.3110, Mead (1999)
Additional information
The ready biodegradability of the test material was investigated in a study which was conducted under GLP conditions and in accordance with the standardised guidelines OECD 301B, EU Method C.4-C and EPA OPPTS 835.3110.
During the study the test material was exposed to activated sewage sludge microorganisms at a concentration of 10 mg C/L with culture medium in sealed culture vessels in the dark at 21 °C for 28 days. The degradation of the test material was assessed by the determination of carbon dioxide produced. Control solutions with inoculum and reference material, sodium benzoate, together with a toxicity control were used for validation purposes.
In order to aid dispersion of the test material in the test system and to increase the surface area of the test maerial available to the activated sewage sludge microorganisms, the test material was adsorbed onto silica gel prior to addition to the test vessels.
The test material attained 39% degradation after 28 days and therefore cannot be considered to be readily biodegradable under the conditions of the study.
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.
