Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
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
Sugar factory lime is not readily biodegradable.
Key value for chemical safety assessment
- Biodegradation in water:
- under test conditions no biodegradation observed
Additional information
The key study (Degussa, 2007) was performed in accordance with EU Method C5 and GLP and was therefore assigned a reliability of 1. The study assessed the ready biodegradability of sugar factory lime (SFL) at concentrations of 1000 and 2000 mg/L over a period of 5 days. The oxygen consumption of the test samples was measured and the degradation of the test material was determined to be equal to 6% and 8% for the 1000 and 2000 mg/L samples, respectively. SFL is therefore not readily biodegradable.
In a preliminary study, the chemical oxygen demand of SFL was determined to be 76.3 mg O2 per gram of test material (Degussa, 2007).
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.
