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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information
DTPMP potassium salts will fully dissociate in aqueous solution, once absorbed and in moist environments like soil and will behave no differently to the parent DTPMP acid and its potassium counter ion at equivalent concentrations. It is not expected that the potassium counter ion will contribute significantly to the overall toxicity of their DTPMP salts. Therefore, the impact on aquatic, sediment, soil and mammalian organisms will be dominated by the affects of the DTPMP acid.
Conclusion on classification
The substance is not classified since the the EC and LC50 values are >1 mg/L (180 mg/L and above), while the long term NOECs are >1 mg/L (60 day with fish is >25.6 mg/L)
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.
