Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Specific gravity is a type of relative density in which the substance density is compared to that of water at 3.98°C.

Conclusions:
The specific gravity of trisodium orthophosphate has been reported as 1.62 at 20°C. This data is considered to meet the regulatory requirements for this endpoint as part of a weight of evidence approach.

Description of key information

In accordance with Annex XI, Section 1.2. of Regulation (EC) No. 1907/2006 (REACH) a weight of evidence approach has been used to fulfil the endpoint '7.4. Relative Density'. Data are provided for the anhydrous form and a hydrated form of trisodium phosphate. Taken together these data are considered to be acceptable to fulfil the endpoint as part of a weight of evidence and no further testing is considered to be justified.

Key value for chemical safety assessment

Relative density at 20C:
1.62
