Description of key information

The test item, Reaction product of naphthalene, propan-2-ol, sulfonated and neutralized by caustic soda, was not considered toxic to Daphnia magna at concentrations of up to 100 mg/L (75.1 mg organic a.i./L). 
The 48-hour EC50 of Reaction product of naphthalene, propan-2-ol, sulfonated and neutralized by caustic soda to Daphnia magna were thus determined to be > 100 mg/L based on the mobility; revealing it is not harmful for the daphnids.

Key value for chemical safety assessment

Additional information

A GLP-compliant study, scored as Klimisch 1 and flagged as a key study, is available on the Reaction product of naphthalene, propan-2-ol, sulfonated and neutralized by caustic soda; giving a 48h-EC50 > 100 mg/L and revealing that the Reaction product of naphthalene, propan-2-ol, sulfonated and neutralized by caustic soda is not harmful to Daphnia magna (M. Anderson, 2013).
