Additional information
The acute toxicity of castor oil, dehydrated to Daphnia magna was tested according to OECD Guideline 202 and EC Method C.2 under static conditions. The study encompassed two treatment groups, each containing 20 individuals. The mobility of the daphnids was determined by visual observation after 24 and 48 h of exposure. Samples collected at start and after 48 h were analysed via the total organic carbon (TOC) method. Due to the low limit of water solubility of the test substance, a Water Accomodated Fraction (WAF) with a nominal loading rate of 100 mg /L and a control were tested. Under the test conditions, the 48 h EC50 of the test substance forDaphnia magnawas determined to be > 100 mg/L. The NOEC and the LOEC were > 100 mg/L.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
