Additional information

The short-term toxicity of Zorgol 48 (1-Hexanol, 2-ethyl-, manuf. of, by-products from, distn. Residues) to aquatic invertebrates was tested under GLP conditions according to OECD TG 202 using five graduate concentrations. Based on measured concentrations (geometric mean of 0 and 48 h concentrations), the 48 h EC50 was determined to be 74 mg/L. The 48 h NOEC was 45 mg/L (Muckle/Laus, 2010b).
