Description of key information
In a study conducted according to OECD Guideline 202 (Daphnia sp. Acute Immobilisation Test) and using Daphnia magna as test organism, the 48– hour EC50 was determined to be > 100 mg/L (limit test) based on the nominal concentration of the test material.
Key value for chemical safety assessment
Additional information
The 48–hr-acute toxicity of Isostearic acid, esters with methyl α-D-glucoside was investigated in a study conducted according to OECD Guideline 202 (Daphnia sp. Acute Immobilisation Test). Under static conditions Daphnia magna were exposed to control, reference substance (potassium dichromate) and the test chemical at a loading rate of 100 mg/l (limit test) for 48 h. Isostearic acid, esters with methyl α-D-glucoside could not be completely dissolved in the test medium at the loading rate tested because the water solubility was visually assessed to be less than 1 mg/l. No analytical control was performed. Immobilization was observed after 24 and 48 h.
The 24 h EC50 was > 100 mg/l (nominal, limit test)
The 48 h EC50 was > 100 mg/l (nominal, limit test).
The NOEC based on immobilization was = 100 mg/l.
Based on the results of this study the test substance Isostearic acid, esters with methyl α-D-glucoside is non-toxic to Daphnia magna (EC50 > maximum soluble concentration).
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).
