Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
For barium 4-dodecylphenolate, aquatic toxicity studies are not vailable. Read-across to the assessment entities soluble barium substances and dodecylphenolate is applied for the assessment of barium 4-dodecylphenolate since the ions of barium 4-dodecylphenolate determine its fate and toxicity in the environment. Reliable data available for soluble barium substances and dodecylphenolate indicate that the moiety of ecotoloxicological concern are dodecylphenolate anions. Based on dissolved barium concentrations in solution, the ErC50and NOEC are >1.15 and >=1.15 mg Ba/L, respectively. According to the QSAR-based outcome of the model ECOSAR v.2.0, dodecylphenolate has a potential for toxicity to algae since the chronic value (ChV = 10^([log (LOEC x NOEC)]/2)) is estimated with 0.023 mg/L.
Thus, barium 4 -dodecylphenolate is expected to have a potential for toxicity to algae.
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.
