Additional information

The acute toxicity of Glycerides, mixed C8-10 and succinyl (CAS No. 91744-56-8) to aquatic invertebrates was investigated in a study by Hafner (2012). This test was conducted according to OECD 202, under GLP conditions. According to the results of a range-finding test conducted under non-GLP conditions, Daphnia magna was exposed for 48 hours to a single nominal loading rate of 100 mg/L (Water Accomodated Fraction (WAF)).The Water Accommodated Fraction (WAF) was prepared by adding the test material into water, stirring for a period of 48 hours, followed by a sedimentation period of 1 hour. After the stirring, the WAF was almost clear, but undissolved test item was observed at the bottom of the beaker. Later on, after the sedimentation period, no particles or undissolved test material were observed. The test solution was prepared without a further filtration step. Analytical measurements of the test concentration were performed via TOC and DOC analysis at the start and at the end of the test. The mean measured concentration was determined to be 10.7 mg/L.


After 48 hours of exposure to the test substance, no immobilization was reported in control or treatment vessels and therefore, the EL50 (48 h) was determined to be > 100 mg/L (loading rate) and > 10.7 mg/L (mean measured concentration).


Based on the above information, no acute toxicity of Glycerides, mixed C8-10 and succinyl to aquatic invertebrates is expected within the limit of the water solubility (WS 1-2 mg/L).
