Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Aquatic toxicity data of barium dilaurate are not available. Read-across to the assessment entities soluble barium substances and lauric acid is applied for the assessment of barium dilaurate since the ions of barium dilaurate determine its fate and toxicity in the environment. Reliable data are available for soluble barium substances and lauric acid (i.e. C12 fatty acid) indicate that the moiety of ecotoxicological concern are barium cations. A reliable, nominal 48h-EC50 of 14.5 mg Ba/L was derived. Aquatic toxicity data of lauric acid point to a low toxic potential to aquatic invertebrates. The ecotoxic potential of the fatty acid chain, i.e. laurate, is assumed to be negligible. Fatty acids are generally not considered to represent a risk to the environment, which is reflected in their exclusion from REACH registration requirements (c.f. REACH Annex V (Regulation (EC) No 987/2008)).
Thus, barium dilaurate is expected to have a low potential for acute toxicity to invertebrates.
Key value for chemical safety assessment
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.
