Kevin, isopropanol is horrible stuff. It's banned for use in the print trade in many countries particularly USA, partially because it's so flammable in it's neat form and partially because of the health implications. Different states seem to put different risks on it, That's why alternatives have been produced. Have a look round the internet for the health implications. Yes, one or two like you will claim it's harmless but the majority won' t. Generally the people who claim it's harmless are the manufacturer's, just Google health implications of isopropanol and read it.
I certainly wouldn't be happy breathing in isopropanol vapour no matter how dilute I had thirty years in the print trade and saw many chemicals come and go, even got a dose of cancer but whether that's related to chemical use - who knows?.
Yes it's also a wetting agent.
That is the only reason it's used in print - to reduce surface tension of pure water in lithography. Other industries use it as a solvent. The stuff evaporates so fast that it is normally cooled on a printing press to about eight degrees in it's mixed form. Probably not a good idea to keep it stored in bulk anywhere near your house/garage because it's as bad as petrol regarding flammability.
Kevin, you as a chemist and blender of products should know all this
