Results

Preliminary Test (non GLP)

The determined solubility was in the range of 4.7 g/L. The samples were checked negative for Tyndall-effects. For the application dose of the definitive study, 50 g/L, as approx. the tenfold of the solubility result was used.

1) Mean values of two injections

2) Calculated according to the formula

The water solubility of Indoflor was determined to be: 3.89 g/L (20 °C, pH 6.7)

 

Conclusions:
A water solubility value of 3.89 g/L (at 20 °C, pH 6.7) was determined for the test substance according to E.U. Method A.6.
