Any other information on results incl. tables
Acid Yellow RN 2903 is a fine dark yellow powder. Under the microscope (with a magnification of 100), small-sized orange colored crystals with some major crystals were observed.
A solubility test showed, that the test item is both: sparingly soluble and well dispersible in 2-propanol. The particle size distribution of Acid Yellow RN 2903 was performed with two samples of the stock dispersion each measured in duplicate.
The individual measurements and the results obtained using the laser diffraction method of Acid Yellow RN 2903 are summarized in Table1 and Table 2. The tables represent rounded results obtained by using the exact measurement data. An example of the particle size distribution curve is shown in the attached Figure1.
The results obtained during the measurements showed no relevant difference. Therefore the study is considered to be valid and no further testing is necessary.
