Description of key information

Based on read-across to 1-DECANAMINE, N-DECYL, N-METHYL, a substance with the same chemical structure, but a shorter alkyl chain length than the substance registered, EC50 value to invertebrates is 0.024 mg/L.

Key value for chemical safety assessment

EC50/LC50 for freshwater invertebrates:
0.024 mg/L

Additional information

The acute toxicity (inhibition of mobility) of the test item 1-DECANAMINE, N-DECYL, N-METHYL for a duration of 48 hours was assessed according to the OECD Guideline 202.

Daphnia magna were exposed under static conditions to a range of concentrations of 1-DECANAMINE, N-DECYL, N-METHYL dissolved in dilution water. The toxic effect measured during the assay was the inhibition of mobility over time periods of 24 and 48 hours.

The maximum effect concentration was 50% of immobilization, corresponding to a measured concentration of 0.02 mg/L. Therefore, only an estimation of the EC50 value by calculation was possible.

The results were as follows:
