- Executive summary:
The water solubility of FAT 40879/B at a temperature of 20 °C was determined according to OECD guideline 105 and EU method A.6 using flask method. In the preliminary visual experiments, the water solubility of the test item was between 500 and 667 g/l. So, based on the study results, the water solubility cs of FAT 40879/B at a temperature of 20 °C was determined (without correction for the purity) to 519 g/l.
Reference
The preliminary visual experiments showed that the water solubility of the test item is between 500 and 667 g/l.
