Reference
Endpoint:
water solubility
Type of information:
experimental study
Adequacy of study:
key study
Study period:
January 15, 2004 - February 3, 2004
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
test procedure in accordance with generally accepted scientific standards and described in sufficient detail
Qualifier:
no guideline followed
Principles of method if other than guideline:
Mixtures of the test substance in water were mixed for 5 days at 24 ± 1 °C, after which they were centrifuged and filtered. The concentration of Ba, Mg and Al was determined by ICP-AES.
GLP compliance:
no
Type of method:
other: measurement of saturated mixtures
Key result
Remarks on result:
other: The substance is insoluble in water.

- Undissolved test substance was present in all the solutions containing test substance after mixing for 5 days at 24 ± 1 °C, showing that the solutions were saturated.

These results show that the used method is suitable for the test substance.

Conclusions:
The substance is insoluble in water, based on the results obtained in a study in which the concentration of 3 elements in saturated mixtures was determined by ICP-AES.

Description of key information

The substance is insoluble in water.

Key value for chemical safety assessment

Additional information

Mixtures of the test substance in water were mixed for 5 days at 24 ± 1 °C, after which they were centrifuged and filtered. The concentration of 3 elements was determined by ICP-AES.
