Conclusion on classification

Lactides undergo rapid hydrolysis, forming lactic acid. Therefore, by way of read-across from lactic acid, the following conclusion on classification and labelling is derived:

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.

In conclusion, DD-lactide 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. Accordingly, no relevant hazards are identified.
