The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
Additional information
The ready biodegradability of Biofert Plusz was investigated in a study conducted according to OECD Guideline 301 B over a period of 28 days and using non-adapted activated sludge as inoculum source. The biodegradation rate was determined by measurement of CO2 evolution. Inoculum blank, procedural/functional control with the reference substance sodium benzoate, and toxicity control using 80 mg/L test material and 20 mg/L reference compound were performed. Biofert Plusz proved to be readily biodegradable and fulfilling the 10-d window criterion (92% biodegradation after 28 d). The functional control reached the pass level >60% after 14 d. In the toxicity control containing both test and reference substance 81% biodegradation based on ThCO2 occurred within 14 d thus indicating that the test item was not inhibitory at the concentration tested.
Due to these results, the performance of further experimental studies on biodegradation, e.g. in surface water, sediment or soil, according to REACH regulation annexes IX and X is not required.
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.
