Specific gravity is a type of relative density in which the substance density is compared to that of water at 3.98°C. Value reported has been rounded down from 1.5235.

Conclusions:
The specific gravity of disodium hydrogenorthophosphate dodecahydrate has been reported as 1.5235. 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 a number of hydrated forms of disodium hydrogenorthophosphate. 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
