Description of key information
In an OECD 202 study, the 48 h EL50 to D. magna was >100 mg/L (highest loading rate tested). This value was adjusted to account for the solvent oil content (40.8%) of the test material; therefore an EL50 value of EC 903-162-9 is >59.2 mg/L.
Key value for chemical safety assessment
Additional information
Testing was conducted in accordance with OECD guideline 202 and to GLP standards. Based on the results of a range finding test, a limit test was conducted with test solution prepared as Water Accommodated Fraction (WAF) from an initial test material loading rate of 100 mg/L, corresponding to 59.2 mg EC 903-162-9/L. A control of untreated Daphnia medium was also included. As the test item is a poorly soluble complex mixture, the method of preparation was selected to maximise the solubility of EC-903-162-9 under test exposure conditions, while minimising exposure to insoluble fractions.
No immobile D. magna were noted throughout the test period. The 48 h EL50 was therefore >100 mg/L (highest loading rate tested), and the no observed effect loading rate (NOELR) is concluded to be 100 mg/L. These values were adjusted to account for the solvent oil content (40.8%) of the test material; therefore the EL50 value and NOELR for EC 903 -162 -9 are >59.2 mg/L and 59.2 mg/L, respectively.
A read across study conducted on an analogue of EC 903-162-9 is also presented in support of the read-across justification provided in IUCLID section 13. The EL50 value for this study was determined to be >1000 mg/L (highest loading rate tested) when tested as a water accommodated fraction. From the results it is clear that both materials do not show signs of aquatic toxicity in the short term toxicity test for Daphnia Magna.
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).
