I can confirm that DAS is insoluble in isopropylalcohol. By adding 3 gram DAS to 50ml 99% isopropyl alcohol the powder stays dispersed in the liquid. By adding 50 ml water it still would not dissolve completely. Only after adding the minimum required quantity of water (100ml) it dissolves. As we know a saturated solution is around 3%. This water/alcohol/DAS mix is a clear solution and looks ok, time will tell if the alcohol has adverse effects on it. I will also test if this alcohol diluted DAS (now 2%) is usable as a brush-on sensitizer.
