Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

- Endpoint:
- appearance / physical state / colour
- Type of information:
- migrated information: read-across from supporting substance (structural analogue or surrogate)
- Adequacy of study:
- key study
- Study period:
- 02/10/2009 -05/11/2009
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: see 'Remark'
- Remarks:
- The substance tested is a hydrated form of the substance to be registered and therefore in accordance with 'Data Submission Manual, Part 18 - How to report substance identity in IUCLID 5 for registration under REACH' the hydrated form is considered to be different to the anhydrous form. Read-across from trimagnesium phosphate-4-hydrate to the anhydrous trimagnesium bis(orthophosphate) is justified on the basis that the addition of water is unlikely to detrimentally affect the physicochemical or (eco)toxicological profile of the substance. The reliability has been amended in accordance with 'practical guide 6: How to report read-across and categories' which states that the maximum reliability for a read-across study is 2. The study is considered to be adequate and reliable for the purpose of registration under REACH (Regulation (EC) No. 1907/2006).
- Qualifier:
- no guideline required
- Principles of method if other than guideline:
- Visual observation
- GLP compliance:
- yes (incl. QA statement)
- Physical state at 20°C and 1013 hPa:
- solid
- Form:
- powder
- Colour:
- white
- Odour:
- other: no data
- Substance type:
- inorganic
- Conclusions:
- Trimagnesium phosphate-4-hydrate has been determined to be a white powder. This study was performed in accordance with an accepted method (visual observation) and under the conditions of GLP.
