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 measured total Ba-levels in the water column, a 96-h LC50 of > 97.5 mg Ba/L (corresponding to > 3.5 mg dissolved Ba/L) is reported for fish. According to the QSAR-based outcome of the model ECOSAR v.2.0, dodecylphenolate has a potential for toxicity to freshwater fish, as the 96-h LC50 was estimated with 0.038 mg/L.
Thus, barium 4 -dodecylphenolate is expected to have a potential for acute toxicity to fish.
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.
