Description of key information
NOELR (21 d): 0.11 mg/L (measured; OECD 211)
Key value for chemical safety assessment
Additional information
One study is available investigating the chronic toxicity of Propanoic acid, 2-hydroxy-, C12-13-branched-alkyl esters to aquatic invertebrates (Höger, 2013). The study was performed according to OECD 211 (GLP) using the water flea Daphnia magna. A test solution of nominal 100 mg/L was prepared and filtered using appropriate methods. The filtrate was further diluted and the five dilutions (1:2, 1:6.3, 1:10, 1:63 and 1:100) were tested in a semi-static exposure regime. Actual concentrations of the dilutions were determined analytically by GC/FID. The concentrations in the freshly prepared test media of the relevant concentrations (NOEC and LOEC) were 0.0611 - 0.141 mg/L (dilution 1:10) and 0.0891 - 0.231 mg/L (dilution 1:6.3), respectively. In the aged test media samples (with and without food), the measured concentrations decreased and were between <LOQ (limit of quantification, LOQ=0.03 mg/L) and 85% of initially measured values. Under the conditions of the test, the test item was not stable during the test medium renewal periods of two and three days. As it is unknown whether the parent molecules (propanoic acid, 2-hydroxy-, C12-13-branched-alkyl esters) or the degradation products are responsible for the toxic effects, all reported biological results were related to the mean of the initially measured concentrations of the test item. At the end of the study an effect on mobility of D. magna was observed with immobilization of 40% at a concentration of 0.18 mg/L. The reproduction was not inhibited. Thus, a NOELR (21 d) of 0.11 mg/L (measured, initial) was derived based on immobilisation.
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).
