Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

- Effect concentration:
- 146 µg/L
Additional information
Three studies are presented for acute toxicity to Daphnia Magna, with the following results:
EC50 (48- h): 146 µg/L test mat. (estimated) based on: mortality (and mobility)
LC50 (48- h): 0.27 mg/L test mat. (nominal) based on: mortality
LC50 (48- h): 0.09 mg/L test mat. (nominal) based on: mortality
The results clearly demonstrate that toxicity is prevalent. As it is known that the phosphates as a group demonstrate toxicity to aquatic organisms, the LC50 value for hazard assessment is taken as146 µg/L. The risk phrase "Very toxic to aquatic organisms" is applicable.
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
