No numerical result is given.
The test substance is reported as miscible in water and no other numerical data has been represented.
Phosphonate salts are highly water soluble and some are formulated as aqueous. Solutions containing up to 70% active material. Free acids are less soluble than the salts; however, aqueous solutions in excess of l % active material can be prepared.
An infinite water solubility value was reported in the handbook which represents the water solubility is greater than >1 *10E+6 (the substance is miscible in water).
The substance is manufactured and marketed in aqueous solutions of various pH values and concentrations. It is known that up to 50% m/m solutions can be prepared, which would have very acidic pH (see section 2.12). At pH 7 the substance is multiply-ionised and solutions of over 50% m/m can be prepared.
The water solubility value of 1000000 mg/L at 25°C was reported for ATMP-H in EPIWIN suite Ver. 4.0 cited with Gledhill WE, Feijtelm TCJ (1992). No pH condition is reported.
Description of key information
Water solubility (ATMP-xNH4): The substance is very soluble in water and has an average water solubility value of >400 g/L at ambient conditions based on available information
Water solubility [ammonia]: 510000-531000 mg/L at 20°C
Key value for chemical safety assessment
- Water solubility:
- 400 g/L
- at the temperature of:
- 20 °C
Additional information
The substance ATMP-xNH4 (and its analogues) are known to be highly hydrophilic and extremely water-soluble. Although supplier's literature is much less detailed than laboratory study reports, given the range of values expected for these types of substance, the uncertainty is not significant in respect of environmental exposure or human health exposure modelling. Typical concentrations of aqueous solutions in commercial supply provides weight of evidence of high loadings. For ATMP-xNH4, the water solubility can be estimated to be equivalent to approximately >400 g/L based on concentrations of 38% for ATMP-xNH4 (pH 4) and 35% for ATMP-xNH4 (pH 7) (concentration range 25-50%) and average density of 1.2 g/cm3 at 20°C.
A water solubility of 1000000 mg/L at 25°C was reported for ATMP-H using appropriate predictive method (US Environmental Protection Agency 2008) and is cited with Gledhill WE, Feijtel, TCJ (1992). In available secondary sources to which reliability could not be assigned, water solubility in the range 500 - 730 g/L were reported for ATMP-H.
Phosphonate salts are highly water soluble and are supplied as aqueous solutions. The aqueous solutions of phosphonate salts are miscible in water.
Ammonia, has a reported water solubility of 510000-531000 mg/L at 20°C (OECD 2007). The reported values indicate that ammonia is highly soluble/miscible with water.
