Description of key information

NOEC=100 mg/L (nominal cocnentration, corrected for water content of test item), Daphnia magna, OECD 202

Key value for chemical safety assessment

Additional information

The acute toxicity of the test item Mexoryl SBO to Daphnia magna was determined in a 48-hour static test according to the EU Commission Directive 92/69/EEC, Part C.2, Commission Regulation (EC) No 440/2008, Part C.2 and the OECD Guideline for Testing of Chemicals, No. 202 (2004). A limit test was performed in accordance with the test guidelines to demonstrate that the test item has no toxic effect on the test organisms up to and including a nominal concentration of 100 mg/L (corrected for the water content of the test item; absolute amount of test item: 183.8 mg/L). Thus, the only nominal concentration tested was 100 mg/L. Additionally, a control group was tested in parallel.

The analytically determined concentration of the test item in the test medium at the start and end of the test was 108 and 101% of the nominal value, respectively. Under the conditions of the test, the test item Mexoryl SBO was stable during the test period of 48 hours.

In the control and at the test item concentration of 100 mg/L out of water (corrected for the water content of the test item; absolute amount of test item: 183.8 mg/L), no immobilized test organisms were observed during the test period of 48 hours.
