Description of key information
Key value for chemical safety assessment
Additional information
The simulation test on ultimate degradation in surface water and sediment simulation test study required in REACH guidance, Annex IX (Sections 9.2.1.2 and 9.2.1.4) do not need to be conducted as the substance is readily biodegradable. The chemical safety assessment also indicates that identification of degradation products (required in section 9.2.3) is not necessary.
However, a biodegradation value of 93 ± 5 % has been determined for citric acid in a test conducted according to OECD 303A (simulation test - aerobic sewage treatment aerobic). The observed removal could be due to adsorption and/or degradation.
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.
