- A density value of 1.3 to 1.4 g/cm³ is reported at 20°C. The result is reported in a company MSDS. The original reference was not available for review and no further information is available. The reliability of this result is not assignable.
- Endpoint:
- density, other
- Type of information:
- read-across from supporting substance (structural analogue or surrogate)
- Adequacy of study:
- weight of evidence
- Justification for type of information:
- Density data for the acid is read-across to the salt due structural similarity. The salts are produced from the parent acid; diethylene triamine penta(methylene phosphonic acid). The read-across is therefore based on the presence of common functional groups in both the acid and the salt . The impurity profile of the salt is expected to be similar to that of the parent acid since the salt is prepared from the acid.

Description of key information
Density :The weight of evidence from company data is for specific gravity values in the range ca. 1.3 - 1.4 g/cm³ at ambient conditions for various commercial solutions.
Key value for chemical safety assessment
Additional information
A number of specific gravity values of individual commercial aqueous products are known. While the individual sources are secondary literature, meaning that in most cases the reliabilities are not assignable, overall the weight of evidence is taken to be adequately reliable for the purpose of registration, particularly in view of the acceptance of the data in the HPV program.
The following company data of non-assignable reliability are available:
1) Values of ca. 1.3 - 1.4 g/cm³ at 20 °C was reported for commercial forms of this substance in the online product specification data for a major European producer.
2) A specific gravity of 1.42 g/cm³ was reported in online product literature for a major European producer. The original reference was not available for review and no further information is available.
3) A typical specific gravity of 1370 to 1410 kg/m3 at 20°C was reported in a company product data sheet for a major European importer. The original reference was not available for review and no further information is available.
