Description of key information
Benzenesulfonic acid, 4-dodecyl-, cerium(4+) salt consists of a cerium cation and a benzenesulfonic acid (4-C10-13-sec-alkyl derivate) anion. In the assessment of the toxicity of benzenesulfonic acid, 4-dodecyl-, cerium(4+) salt to aquatic invertebrates, read-across to the assessment entities soluble cerium substances and benzenesulfonic acid (4-C10-13-sec-alkyl) anions is applied since the ions of benzenesulfonic acid, 4-dodecyl-, cerium(4+) salt determine its fate and toxicity in the environment.
Regarding cerium toxicity in aquatic environments, a 48-h EC50 of 6.9 mg Ce/L was derived for D. magna. For benzenesulfonic acid (4-C10-13-sec-alkyl-derivates), a OECD 202 conform study with sodium 4-undecylbenzenesulfonate (CAS: 68411-30-3) as a representative substance resulted in a 48-h EC50 of 2.9 mg/L for D. magna.
Thus, benzenesulfonic acid, 4-dodecyl-, cerium(4+) salt appears to have some potential for acute toxicity to aquatic invertebrates due to the toxicity of its dissociation products.
Key value for chemical safety assessment
