Description of key information

Calcium lactate is readily biodegradable.

Key value for chemical safety assessment

Biodegradation in water:
readily biodegradable

Additional information

Calcium lactate fully dissociates into Ca2+ ions and lactate in aqueous environments. The biodegradation of calcium lactate in the environment can be understood in terms of the biodegradation of lactic acid.

Based on unequivocally positive QSAR predictions (BIOWIN v4.10) and a supporting study investigating the biochemical oxygen demand (BOD) lactic acid is considered to be readily biodegradable, and therefore calcium lactate is considered to be readily biodegradable.
