Description of key information

Sodium lactate fully dissociates into Na+ ions and lactate. The ecotoxicology of sodium lactate can be understood in terms of the ecotoxicology of lactic acid. molar ratio to convert from lactic acid by weight to sodium lactate by weight is 1.24.
Three short term toxicity studies with lactic acid with fish are available. The key study shows an LC50 (nominal) of 130 mg/L. This corresponds to 162 mg/L sodium lactate.

Key value for chemical safety assessment

LC50 for freshwater fish:
162 mg/L
