Description of key information
The ready biodegradability of the test material was investigated according to the OECD guideline 301 F (1992). All validity criteria were fulfilled. The reaction mass reached the pass level of 60% for ready biodegradability in the Manometric Respirometry Test within the 10-d window and, therefore, can be termed as readily biodegradable. The procedure control sodium benzoate reached 86% biodegradation after 14 days, thus confirming suitability of inoculum and test conditions.
Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
Additional information
The biodegradability of the reaction mass exposed to microorganisms derived from activated sludge of a municipal sewage treatment plant was investigated under aerobic static exposure conditions. The reaction mass was completely biodegraded after an incubation time of 28 days as compared to the chemical oxygen demand (COD), The biodegradation of the reaction mass reached 100% at the end of the 10-d window. Biodegradation of the test item was observed without any significant lag-phase. The procedure control sodium benzoate reached 86% biodegradation after 14 days, thus confirming suitability of inoculum and test conditions. The elimination based on dissolved organic carbon (DOC) analyses was calculated to be 100% for the reaction mass and sodium benzoate, respectively. These data confirm the complete biodegradability of the test material. The reaction mass reached the pass level of 60% for ready biodegradability in the Manometric Respirometry Test within the 10-d window and, therefore, can be termed as readily biodegradable.
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.
