Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

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.
Results are reproduced below.
| Species | Endpoint | Concentration | Result Parameter | Reliability (Klimisch) |
Invertebrate Daphnia magna |
48-hr EL50 | > 100 mg/L (nominal) |
Immobilization | 2 (reliable with restrictions) |
Algae Pseudokirchneriella subcapitata |
72-hr EL50 | > 100 mg/L (nominal) |
Growth Rate | 1 (reliable without restrictions) |
Algae Pseudokirchneriella subcapitata |
72-hr EL10 | > 100 mg/L (nominal) |
Growth Rate | 1 (reliable without restrictions) |
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).
