Description of key information
72h EC50 (Desmodesmus subspicatus, growth rate) > 20 mg/L (nominal, EU Method C.3)
72h EC10 (Desmodesmus subspicatus, growth rate) = 5.4 mg/L (nominal, EU Method C.3)
Key value for chemical safety assessment
- EC50 for freshwater algae:
- 20 mg/L
- EC10 or NOEC for freshwater algae:
- 5.4 mg/L
Additional information
For C12 -13 alkylsulfates (CAS 1231880 -35 -5) no test on algae is available. Thus a read-across is performed to the comparable mixture C12 -14 alkylsulfates (CAS 85586 -07 -8). In this study toxicity of the C12-14 mixture on aquatic algae was investigated in a study with Desmodesmus subspicatus according to EU Method C.3 (Scholz, Elementis, 1995). The GLP-study resulted in an EC50 (72 h)-value for growth rate of > 20 mg/L as a-WAS. The corresponding NOEC (72 h) for growth rate was 0.6 mg/L as a-WAS. This test is regarded as key study.
