Description of key information
Based on read across studies for short-term toxicity to aquatic invertebrates on chemically similar substances, for the target substance Fatty acids, C14-18 and C16-18-unsatd., ammonium salts the EC50(daphnia, 48h/24h) is estimated to be >=4.2 mg/l (to <= 40 mg/l).

Additional information
Several publications are available in which the short-term toxicity to aquatic invertebrates of the analogue substances (Sodium oleate, Sodium myristate, Sodium stearate, Sodium palm kernel soap, Sodium tallow soap) were determined. The test took 24 hours respectively 48 hours. As results, following (lowest) EC50 values were determined: 4.2 mg/L for Sodium oleate, >20 mg/L for Sodium myristate, 19 mg/L for Sodium stearate, 25 mg/L for Sodium palm kernel soap and 40 mg/L for Sodium tallow soap.
Based on the structural similarity of the target substance to the analogue substances the results of the short-term toxicity to aquatic invertebrates of the source substances can be assigned to the target substance.
The supporting information of the short-term toxicity to aquatic invertebrates of the analogue substances sodium laurate (EC50(daphnia, 24h): 48 mg/l) is given but is less appropriated for the read-across projection to short-term toxicity to aquatic invertebrates of the target substance (because laurate is an impurity).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
