I found this, which does not mention what I thought I read earlier about mineral oil as a carrier. It doesnt' tell us why alcohol is a good carrier, but it says it is used. Working it in a blender might help too.
"The most popular carrier for OC is isopropyl alcohol. Other options include, but are not limited to, Freon, Dymel-22, Dymel-134, Genetron-141B, methylene chloride, and water"
and I also learned that the active principle is a very strong alkaloid, capsaicin, which is found in paparika oleoresin, so the capsaicin might disolve or otherwise be suspended in water or alcohol, regardless what the oleoresin does. Alkaloids can be extracted with acids, including sometimes citric acid, but vinegar might also help suspend the active ingredient in a carrier. Is there a chemist in the house?
