Executive summary:

Based on the prediction done using ECOSAR version 1.1, the long term toxicity on aquatic invertebrate was predicted for test substance . On the basis of effects observed in a static freshwater system, the NOEC value for the test substance is estimated to be 20.059 mg/l for aquatic invertebrate for 21 days of exposure,The test substance is redialy biodegradable in aquatic environment it can be concluded that the test chemical can be considered as non-toxic to aquatic invertebrate at environmentally relevant concentrations and can be considered not-classified as per the CLP classification criteria.
