Additional information

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. No environmental hazards have been identified.

Conclusion on classification

Lactic acid is practically non-toxic 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 need to be classified for environmental hazards, 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 identified.
