Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

PBT assessment
Administrative data
PBT assessment: overall result
- PBT status:
- PBT assessment does not apply
- Justification:
According to the Guidance on Information Requirements and Chemical Safety Assessment, Chapter R.11: PBT Assessment (2014) PBT and vPvB criteria are not applicable to inorganic substances.
Persistence Assessment
The concept of biodegradation is not applicable to inorganic substances (OECD, 2001). Both Magnesium and phosphorus are abundant elements being persistent in the environment and essential for organisms.
Bioaccumulation assessment
Bioaccumulation of magnesium dimetaphosphate (CAS 13573-12-1) is not the point of concern for the environmental risk assessment. Magnesium and phosphorus are essential for biochemical functions of cells. As micronutrients the internal concentrations of Mg and P will be regulated by biochemical processes and metabolism of organisms. This suggested that environmental and dietary exposure ofmagnesium dimetaphosphate is unlikely to pose risk of Mg and P accumulation to organism. A risk of secondary poisoning is therefore not anticipated.
Toxicity assessment
Magnesium dimetaphosphate (CAS 13573-12-1) is not expected to be toxic. The available read across data demonstrate no acute toxicity to fish, Daphnia or algae. A chronic toxicity of the substance is not anticipated. The substance is not classified as carcinogenic, mutagenic, toxic for reproduction, noris there any evidence of chronic toxicity according to Directive 67/548/EEC and Regulation (EC) No 1272/2008.
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.
