Conclusions:
On the basis of EPI suite, ECOSAR version 1.1, the LC50 value for short term toxicity to fish was predicted to be 722.57 mg/l for sodium 2-[(1-oxododecyl)amino]ethanesulphonate (CAS: 70609-66-4) in 96 hrs. Based on the LC50 value, it can be concluded that the substance sodium 2-[(1-oxododecyl)amino]ethanesulphonate (CAS: 70609-66-4) can be considered as not toxic to aquatic environment and thus can be considered as “not classified” as per the CLP criteria.
Executive summary:

On the basis of EPI suite, ECOSAR version 1.1, the LC50 value for short term toxicity to fish was predicted to be 722.57 mg/l for sodium 2-[(1-oxododecyl)amino]ethanesulphonate (CAS: 70609-66-4) in 96 hrs.
