Can I dissolve IBA from talc powder?

My container of in total 25 grams of rooting powder contains 2.5 mg IBA (Indole-3-butyric acid), which is mixed with talc powder and a tiny bit of chromium(III)oxide. I know talc is not soluble in water or ethanol. But is it possible to add ethanol to dissolve only the IBA? The talc will then remain in my solution. Is this correct?
