My question is very direct. Does alcohol underpainting for a soft pastels effect the archival quality of a pc of art?

It normally should not affect the life of your work if all your materials are archival quality and acid free. Alcohol evaporates quickly and does not stay in the substrate. If your ground is sensitive to alcohol and will degrade, then all bets are off.

Not all alcohols are the same. If you have doubts about the type of alcohol used for the underpainting, I'd suggest doing a search on google and find out more about its properties.

I did this before using isopropyl alcohol (our household rubbing alcohol) with my pastels. Bob Rohm (a well known international artist) uses denatured alcohol for his underpaintings. I've used that too but the rubbing alcohol is cheaper and quicker to purchase in the grocery or drug store. Both dissipate completely and leave no residue in your painting or on your substrate.
