Description of key information
Density: Company data indicate density in the range 1.2 - 1.3 g/cm3 at ambient conditions for various major commercial aqueous solution products.
Key value for chemical safety assessment
Additional information
No relative density of solid values are available, but this does not constitute a data gap since no solid ATMP ammonium salt products are known. A number of specific gravity values of individual commercial products (acid and salt forms) 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.
1) Density value of 1.2 -1.3 g/cm3 at 20°C was reported for ATMP-xNH4 (pH 4 and pH 7) in a company MSDS
2) A relative density of 1.33 at 20°C was reported in a reliable reference source. The same result is repored in a peer-reviewed data profile published through the OECD HPV program, which is considered reliable with restrictions. This is supported by the following company data of non-assignable reliability:
3) Values of 1.3 g/cm³ at 20°C for four separate commercial forms of this substance are listed in the online product specification data for a major European producer.
4) A specific gravity of 1320-1360 kg/m³ at 20°C was reported in a company MSDS for a major European producer. The original reference was not available for review and no further information is available.
5) A typical specific gravity of 1.33 ± 0.02 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.
6) A specific gravity of 1.33 at 20°C was reported in a company MSDS for a major European producer. The original reference was not available for review and no further information is available.
