Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Additional information

Experimental results are available for the three trophic levels (fish, Daphnia and algae). Two reliable OECD guideline studies are available for Sugar Factory Lime (SFL), which assess its toxicity to Daphnia magna and algae at a concentration of 100 mg/L based on the water accommodated fraction. These studies give EC50 values >100 mg/L and therefore demonstrate that SFL is not acutely toxic. Three reliable OECD guideline studies are also available for calcium carbonate (nano), two of which (fish and Daphnia) were conducted at limit tests of 100% v/v saturated solution. The algal study was conducted at a measured initial test concentration of 14 mg/L, which was the highest concentration that could be achieved. These studies show that the concentration of calcium carbonate (nano) that might cause acute toxicity is greater than the highest concentration tested and therefore exceeds 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 aquatic organisms and PNECs for the aquatic compartment have not been derived.
