Procedure:
Solubility tests in ratios of 1+10, 1+1 and 10+1 of the test item Carbazat (KGD1409) in demineralized water were prepared in 20 ml beaded rim bottles. The exact initial weights of the test item and the exact weights of the demineralized water are listed in table 1. The bottles were tightly stoppered and then agitated with a magnetic stirrer and alternate mechanical shaking at room temperature (20 °C).
The results of the tests shows, that the test item Carbazat (KGD1409) was soluble in demineralized water in each ratio after 5 – 15 minutes.
