Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
No terrestrial studies are available for sugar factory lime (SFL). However, three reliable OECD guideline studies are available which demonstrate the effects of calcium carbonate (nano) on terrestrial species. The species studied were Eisenia foetida(earthworm), plants (soybean, tomato and oat) and soil microorganisms. The tests were all performed as limit tests using a calcium carbonate (nano) concentration of 1000 mg/kg. The results of these studies demonstrate that the concentration of calcium carbonate (nano) that might cause toxicity to terrestrial species is greater than the highest concentration tested and is therefore greater than the maximum solubility of calcium carbonate in water.
The results from studies performed with calcium carbonate (nano) are directly applicable to SFL. On this basis, SFL is not acutely toxic to terrestrial organisms and PNECs for the terrestrial compartment have not been derived.
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.
