Description of key information

The test item consists of Silicium oxide and Aluminium oxide. Silicium could not be measured in the low concentrations which were expected. Qualitative analysis of the first fractions showed no presence of Silicium. Therefore, it was decided to use the Aluminium content only for the determination of the solubility of the test item. All samples showed values below the LOQ. If the measured absorptions were regarded as valid, the resulting concentrations would lie in a range of 0.1 mg/L Al in the concentrated samples, giving 0.01 mg/L Al in the undiluted samples and approx. 0.04 mg/L test item in solution. The solubility of the test item is stated as < 0.07 mg/l.

Key value for chemical safety assessment
