Description of key information

In a test,  with Benzenesulfonic acid, 4-C10-13-sec alkyl derivs., compds with N-(3-dimethylaminopropyl)-2-methyl-propenamide (1:1)performed according to OECD 201, the EC50 based on growth rate, was determined to be 173 mg a.i./L. 

Key value for chemical safety assessment

EC50 for freshwater algae:
173 mg/L
EC10 or NOEC for freshwater algae:
9.6 mg/L

Additional information

One test performed with Benzenesulfonic acid, 4-C10-13-sec alkyl derivs., compds with N-(3-dimethylaminopropyl)-2-methyl-propenamide (1:1), is available. The study was performed according to OECD 201 and in accordance with GLP. There were no deviations from the guideline and the study is considered to be reliable without restrictions.
