Description of key information
No toxicological effects on aquatic invertebrates were observed up to the limit of the water solubility of Fatty acids, C16-18 and C18-unsaturated, branched and linear.
Key value for chemical safety assessment
Additional information
One study, investigating the short-term toxicity to aquatic invertebrates of Fatty acids, C16-18 and C18-unsaturated, branched and linear (CAS No. 68955-98-6) is available.
This OECD 202 acute immobilisation study for Fatty acids, C16-18 and C18-unsaturated, branched and linear was conducted under static test conditions and with Daphnia magna (Sewell, 1994). During the test no immobilised daphnids or other adverse effects were observed during the 48h test period exposed to a 1000 mg/L Water Accommodated Fraction loading rate (EL50 > 1000 mg/L).
Based on this result, it can be concluded that no toxicological effects on aquatic invertebrates are expected up to the limit of water solubility for Fatty acids, C16-18 and C18-unsaturated, branched and linear (15 mg/L).
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).
