Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Calcium lactate fully dissociates into Ca2+ ions and lactate. The ecotoxicological effects of lactate in the environment can be understood in terms of the ecotoxicological effect of lactic acid. Calcium ions - i.e. simple calcium salts, are non-toxic.
Lactic acid is practically nontoxic to algae. This is an additional indication that the short-term effects observed for fish and daphnids are of a physical nature, since algae are less sensitive to pH effects than (especially) fish.
Key value for chemical safety assessment
- EC50 for freshwater algae:
- 3 390 mg/L
- EC10 or NOEC for freshwater algae:
- 2 300 mg/L

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.
