Additional information

One toxicity study was performed to assess the chronic toxicity of dicyclohexylphthalate to Daphnia magna. The study was conducted under GLP and according to OECD Guideline 211. The study was conducted in a semi-static system. Daphnia were exposed to the substance at a range of concentrations from 0.2 to 2 mg/L in freshwater. Based on data obtained the NOEC was determined to be 0.181 mg/L. This value should be used for classification and risk assessment purposes.
