also are all the isopropyl's oil based?
None of them are oil based.. The term means will they mix easier with water or oil... It has to do with polar and non-polar I belive.. I will leave this one to Chemo so i don't screw up...
You are right Curt, like dissolves like, so if they are polar they should dissolve, just don't know if they are polar or not. If they are polar then they will dissolve in water, nonpolar in oil.
Those are all water soluble...
Isopropyl's are usually water soluble unless very long chains.
