Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Environmental fate and pathways
Degradation: Readily biodegradable (69% after 28 d, OECD 301F)
Bioaccumulation: log Kow: 4.13 at 20 °C (EU Method A.8, Estimation method)
Aquatic acute toxicity: Aquatic invertebrates (freshwater):
EC50 (48 h): > 0.483 mg/L (Daphnia magna, OECD 202, based on measured concentration of time weighted average)
Algae (freshwater): ErC50 (72 h): >0.0455 mg/L (Pseudokirchneriella subcapitata, OECD 201, based on measured concentration of time weighted average)
Aquatic chronic toxicity:
- Algae (freshwater): ErC10 (72 h): >0.0455 mg/L (Pseudokirchneriella subcapitata, OECD 201, based on measured concentration of time weighted average)
Conclusion on Classification
Based on the data above of the esterification product of C16-C18 even numbered, saturated fatty acids and lactic acid, sodium salt (EC No. 263-218-7, CAS 61792-31-2) is rapidly biodegradable and has a potential for bioaccumulation based on the log Kow of 4.13. Acute aquatic toxicity data are available for two trophic levels (aquatic invertebrates and algae) whereas chronic toxicity was only investigated for aquatic algae. No acute or chronic hazard was indicated up the highest achievable concentration. Therefore, the substance does not need to be classified and labeled according to the consolidated version of Regulation (EC) No 1272/2008 and further amendments (ATPs).
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.
