Results and discussion

Any other information on results incl. tables

The preparation of a stock solution was not successful. The resulting suspension is heterogeneous with most of the pigment accumulated in a foam-like upper phase. It is an indication that the pigment is too hydrophobic and thus it is not sufficiently wetted by water. This makes it impossible to perform all other steps in accordance to the guideline TG-318. Thus the evaluation of the stability of Pigment Yellow 128 in simulated environmental media is not possible.
