Description of key information

Additional information

All aquatic toxicity studies were performed in accordance with internationally-accepted test guidelines and Good Laboratory Practice (GLP) standards.

Because MTDID 28640 is a complex mixture, Total Organic Carbon (TOC) was analyzed as a proxy for the chemical, to confirm presence of dissolved chemical over the period of the test. The algae results are considered reliable without restrictions. In the Daphnia magna test, some immobilization was observed, but it was not dose responsive and the result was therefore assigned a Klimisch 2 reliability. All results are considered suitable for purposes of Risk Assessment, Classification & Labeling, and PBT Analysis.
