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).
