Additional information
The ready biodegradation of Quaternary Ammonium compounds, tri-C8-C10-alkylmethyl, Methosulfate was investigated in a study conducted according to OECD Guideline 301 B (Ready Biodegradability: CO2 Evolution Test) over a period of 28 days and using activated sludge obtained from a municipal wastewater treatment plant as inoculum. The biodegradation rate was determined by measurement of CO2 -evolution. Inoculum blank and procedural/functional control with the reference substance sodium benzoateniline were performed. A toxicity control was included in the study.
Under the test conditions the test item is classified as not readily biodegradable within the 28 day period 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.
