Description of key information

The acute toxicity of sodium L(-) lactate to the fresh-water crustacean Daphnia magna was determined as decribed in the OECD Guideline no. 202 and according to the OECD principles of Good Laboratory Practice. No effects on immobilization or condition were reported at 6000 mg sodium L(-) lactate/L.

Key value for chemical safety assessment

Additional information

No adverse effects of sodium lactate were observed in a short-term toxicity test with the fresh-water crustacean Daphnia magna at concentration up to 6000 mg/L which is used for read-across to calcium lactate. Sodium lactate and calcium lactate fully dissociate to lactate and Na+ or Ca2+. Sodium and calcium ions are natural present in water and both are essential nutrients to Daphnia. The ecotoxicological effects of sodium- or calcium lactate in the environment can be understood in terms of the ecotoxicological effect of lactate. Based on the absence of effect for sodium lactate at concentrations 60 times the limit concentration (100 mg/L) it is considered safe to conclude that no effects for calcium lactate occur at the limit concentration either.

This indicates that no hazard has been identified.
