Description of key information

No effect on fish up to the limit of the water solubility of the category members Fatty Acid Glycerides was observed.

Key value for chemical safety assessment

Additional information

Five short-term studies with freshwater fish are available for four different substances (CAS No. 67701-33-1, 73398-61-5, 8001-78-3, 67701-30-8). In all five semi-static studies over 96 hours with Danio rerio no effect up to the limit of the water solubility of the test substances was observed.

Four tests were conducted according to ISO 7346-1 Part 2 under semi-static conditions. In these tests the test substance was directly weighed into the test vessels and undissolved test substance was not removed. The fifth study (CAS No. 73398-61-5; Scholz 1994) was conducted according to the EU-method C.1, which is equivalent to OECD guideline 203. For this limit test water accommodated fractions (WAF) were prepared by filtration of the test solution. In the freshly prepared test solutions the DOC was measured. The result (LC0 ≥ 53 mg/L) was based on the mean concentration of these measurements which were varying from 17 to 104 mg/L. As the water solubility of the test substance is < 1 mg/L no complete separation of the test substance was achieved.

Thus, no effect on fish up to the limit of the water solubility for all category members Fatty Acid Glycerides is assumed.
