Link to relevant study record(s)
- Endpoint:
- water solubility
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- From 9 Dec 2009 to 26 Apr 2010
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.6 (Water Solubility)
- Deviations:
- yes

- Key result
- Water solubility:
- 468.7 g/L
- Conc. based on:
- test mat.
- Temp.:
- 20 °C
- pH:
- 4.3
- Key result
- Water solubility:
- 119.6 g/L
- Conc. based on:
- element
- Temp.:
- 20 °C
- pH:
- 4.3
- Details on results:
- The magnesium concentration measured between the three sampling dates between 96h and 144h differed not more than 15% during the sampling dates and no tendency of increasing values were observed. So a saturation of the water phase with the test item in this period can be assumed and the water solubility is calculated as the mean value of the results between 96h and 144h.
- Conclusions:
- Interpretation of results: very soluble (> 10000 mg/L)
Magnesium chloride is very soluble - Executive summary:
The water solubility of magnesium chloride anhydrous was determined according to OECD Guideline 105 and EC method A.6 (92/69/EC).
The water solubility of Magnesium Chloride Anhydrous was determined in bidistilled water (being in equilibrium with atmospheric carbon dioxide) at 20°C +/- 0.5°C.

Reference
As it is not appropriate to include the chemical combined water into the water solubility, it was stated as the water solubility of MgCL2 anhydrous.
Description of key information
The water solubility of magnesium chloride anhydrous was determined according to OECD Guideline 105 and EC method A.6 (92/69/EC), using the flask method.
The water solubility of Magnesium Chloride Anhydrous was determined in bidistilled water (being in equilibrium with atmospheric carbon dioxide) at 20°C +/- 0.5°C.
The water solubility of Magnesium Chloride Anhydrous in bidistilled water (being in equilibrium with atmospheric carbon dioxide) at 20 °C +/- 0.5°C was determined to be 468.7 g/L. The pH of the saturated solution was pH 4.3.
Key value for chemical safety assessment
- Water solubility:
- 468.7 g/L
- at the temperature of:
- 20 °C
Additional information
The water solubility of the MgCl2 was investigated in one GLP-compliant study performed in accordance with standard methods, without deviations impacting the results of the study. The study is considered as reliable (Klimisch 1) and is selected as a key study for the endpoint.
An additional value of 546 g/L from the handbook "Ullmann's Encyclopedia of Industrial Chemistry. 5th ed" was found in the HSDB.
According to the high water solubility of the Magnesium Chloride, a Transformation/Dissolution protocol (T/Dp) does not seem relevant for the ecotoxicological assessment of the substance.
