Description of key information

The ECOSAR model v.1.11 (EPISuite v.4.10) estimated the 48 hour LC50 for the test material to daphnia to be 78.695 mg/L.

Key value for chemical safety assessment

EC50/LC50 for freshwater invertebrates:
78.695 mg/L

Additional information

The toxicity potential of the test material to daphnia was estimated using a validated QSAR model, the ECOSAR model v.1.11 (EPISuite v.4.10).

The structure-activity relationships (SARs) presented in this program are used to predict the aquatic toxicity of chemicals based on their similarity of structure to chemicals for which the aquatic toxicity has been previously measured. Most SAR calculations in the ECOSAR Class Program are based upon the octanol/water partition coefficient (Kow). Various surfactant SAR calculations are based upon the average length of carbon chains or the number of ethoxylate units.

The toxicity of the test material to daphnids was estimated using the Neutral Organic class of ECOSAR.

The ECOSAR model v.1.11 (EPISuite v.4.10) estimated the 48 hour LC50 for the test material to daphnia to be 78.695 mg/L.
