Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
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 a ubiquitous and essential molecule of life; acute effects, as well as (external) long-term effects are most likely the results of physical processes (pH-effect; electrostatic effects). Chronic effects are not relevant in the context of risk assessment. PNECs are derived based on the acute effects. PNECs are below the chronic no-effect levels, insofar available.Conclusion on classification
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.
Lactic acid does not have to be labeled for environmental effects, and no short or long-term effects are expected for any exposure levels that do not lower the pH to unacceptable levels. As such no relevant hazards are foreseen.
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.
