Description of key information

Category members (Amino Acid Alkyl Amides, Sodium or Potassium Salts) were not found to be significant toxic to neither aquatic invertebrates nor aquatic algae.

Additional information

A collection of the aquatic toxicity is available for category members. All found values are listed below. 

EC number

Short-term toxicity to aquatic invertebrates

Toxicity to aquatic algae and cyanobacteria


S1 - EC: 918-984-3

EC5048 h Daphnia magna: 45 mg/l

EC50 ca. 76 mg/L


readily biodegradable

S2 - EC: 927-837-2

The results obtained on the ecotoxicological endpoint "immobilisation" give an EC5048h superior to the highest tested concentration (i.e 100 mg/l), value expressed in mg/l of the nominal item concentration.

No sign of stress was observed on the daphnids during the 48 hours of the experiment.

ErC50= 136.6 mg/l (extrapolated value expressed in nominal concentration)

ErC50= 1.33 g/l (extrapolated value expressed in nominal concentration)

NOEC= 10.0 mg/l

LOEC = 100.0 mg/l

readily biodegradable


Overall, considering (i) aquatic toxicity values for invertebrates and algae and (ii) that the substances are readily biodegradable, the registered substance is not expected to be toxic.

According to Regulation (EC) n. 1272/2008, the registered substance should not be classified for the aquatic toxicity because the available data are judged as "conclusive but not sufficient for classification".
