Short-term toxicity to aquatic invertebrates
Administrative data
Link to relevant study record(s)
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, butanol, sulfonated and neutralized by caustic soda to Daphnia magna were thus determined by analogy (Read across approach) 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
The short-term toxicity to aquatic invertebrates of Reaction product of naphthalene, butanol, sulfonated and neutralized by caustic soda is determined by a read-across approach based on analogue substance Reaction product of naphthalene, propan-2-ol, sulfonated and neutralized by caustic soda.
A GLP-compliant study, scored as Klimisch 2 and flagged as a key study, is available on Reaction product of naphthalene, propan-2-ol, sulfonated and neutralized by caustic soda; giving a 48h-EC50 > 100 mg/L and revealing that Reaction product of naphthalene, propan-2-ol, sulfonated and neutralized by caustic soda is not harmful to Daphnia magna (M. Anderson, 2013).
