Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
Based on ample data collected from studies with alkyl lactates and fatty alcohols, the 96h-LC50 for freshwater fish is estimated at 0.28 mg/L. Based on GLP studies according to OECD guidelines, the 48h-EC50 for Daphnia magna is 0.0 64 mg/L and the ErC50 for Algae at > 1.8 mg/L. Estimated chronic exposure of Daphnia magna to the combined alkyl lactates resulted in a values of 0.023 mg/L. However, as both the C12 -15 alcohols and lactate esters are readily biodegradable, prolonged environmental exposure of aquatic organisms is considered as less relevant. Toxicity to microorganisms appeared to exceed a loading of 40 mg/L, which was used in a biodegradation test. Microbial activity was not inhibited and the constituents of propanoic acid, 2-hydroxy-, C12-15-alkyl esters were readily biodegradable.
Additional information
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.
