Description of key information

No long-term toxicity test with aquatic invertebrates is available, but no long-term effects can be expected.

Key value for chemical safety assessment

Additional information

There is no long-term test on aquatic invertebrates available for Fatty acids, C18-unsaturated, dimers, hydrogenated (CAS No. 68783-41-5). However, one study investigating the chronic toxicity to fish is available. A NOEC of ≥ 0.85 mg/L (mean measured) was determined. As the water solubility of the test substance was determined to be < 0.52 mg/L, no effects within the water solubility of Fatty acids, C18-unsaturated, dimers, hydrogenated (CAS No. 68783-41-5) were observed.

As there was no sign that aquatic invertebrates are more sensitive than fish in the short term tests, it cannot be expected that a long-term test with aquatic invertebrates will generate different results than the existing long-term test with fish.

Thus, a long-term study on aquatic invertebrates is not required.
