Additional information
Conclusion on classification
Ammonium-(S)-lactate fully dissociates into NH4+ ions and lactate, is readily biodegradable, does not bioaccumulate and has low potential for adsorption to sediment and soil. The ecotoxicology of ammonium lactate can be understood in terms of the ecotoxicology of ammonium and lactic acid. No adverse effects of lactic acid or ammonium relevant for classification and labelling have been observed in the acute and prolonged aquatic toxicity studies with fish, daphnids and algae. Therefore, ammonium-S-lactate is not classified for environmental hazards.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
