Key value for chemical safety assessment

Additional information

The acute toxicity of Glycerides, palm-oil mono-, hydrogenated, acetates (CAS No. 93572-32-8) to fish species was investigated in a study by Hoke (2012). The test was conducted according to OECD 203, under GLP conditions under a static water regime. The test organism Oncorhynchus mykiss was exposed to the test substance for 96 h at 12 ± 1°C. Analytical monitoring of the test concentration (limit test, 120 mg/L nominal) was performed. The measured concentration is above the water solubility value estimated for this substance (1.3-7.4 mg/L). The substance is a complex UVCB and therefore, two representative components were chosen to monitor the concentration in the test solution. These components were probably the most water soluble.

After the exposure period, no lethal or sublethal effects were observed in test organisms and therefore, the LC50 (96 h) was determined to be > 77.9 mg/L (mean measured concentration).
