Conclusion on classification:

Regarding the classification as "hazardous to the aquatic environment", aquatic toxicity studies with benzenesulfonic acid, 4-dodecyl-, cerium(4+) salt are not available, thus aquatic toxicity is addressed with existing data on the dissociation products. The aquatic hazard assessment is based on the most toxic moiety, i.e. cerium cations for the trophic level of algae and aquatic plants but benzenesulfonic acid, 4-C10-13-sec-alkyl derivatives for the trophic level of aquatic invertebrates. Existing aquatic toxicity data of the dissociation products are therefore recalculated for benzenesulfonic acid, 4-dodecyl-, cerium(4+) salt based on a maximum cerium content of 59.5 % and a maximum content of benzenesulfonic acid, 4-C10-13-sec-alkyl derivatives of 51 % (see also endpoint summary "Aquatic toxicity").

Acute (short-term) toxicity: Reliable acute aquatic toxicity data are available from guideline studies for algae and invertebrates. The lowest recalculated EC/LC50 values for benzenesulfonic acid, 4-dodecyl-, cerium(4+) are the 72-h EC50 of 1.06 mg/L for algae and the 48-h EC50 of 5.69 mg/L for Daphnia magna. Therefore, benzenesulfonic acid, 4-dodecyl-, cerium(4+) does not meet classification criteria as short-term hazard to the aquatic environment according to Regulation (EC) No 1272/2008 and its subsequent adaptations.

Chronic (long-term) toxicity: Reliable chronic aquatic toxicity data for benzenesulfonic acid, 4-dodecyl-, cerium(4+) are available for thel trophic level of algae and aquatic plants. Based on classification criteria for substances for which chronic toxicity data are available for one or two trophic levels, criteria in Table 4.1.0(b)(i) and Table 4.1.0(b)(iii) are applied in accordance with Figure 4.1.1 of Regulation (EC) No 1272/2008. Based on the 72-h NOEC of 0.77 mg/L for the trophic level of algae and aquatic plants, benzenesulfonic acid, 4-dodecyl-, cerium(4+) salt would meet classification criteria of Category Chronic 2 (criteria in Table 4.1.0(b)(i)). Based on the 48-h EC50 of 5.69 mg/L for the trophic level of invertebrates, benzenesulfonic acid, 4-dodecyl-, cerium(4+) salt would meet classification criteria of Category Chronic 2 (criteria in Table 4.1.0(b)(iii)). According to the most stringent outcome, benzenesulfonic acid, 4-dodecyl-, cerium(4+) salt classifies as long-term aquatic hazard Category 2 under Regulation (EC) No 1272/2008 and its subsequent adaptations.
