i bet if you try to distil it with 9 parts water, it will bubble up and foam over instead of distilling...
and i bet you have no rig.
so, IMHO, just check if it's non-toxic soap, make the ghb, and bee sure to bioassay it personally before allowing other humans to consume it.
hmm, might want to boil some of that dish soap with NaOH solution for awhile as a test, to see if it degrades and gives any nasty colors... then neutralize it and drink to test the taste

swim remembers dreaming of wearing an ear-to-ear grin as he walked down the street with a 5gallon jug of gbl he had just picked up from the campus post-office. guy asks swim, what's in the box? swim says, is it my new monitor? guy says, no, it's liquid. swim walks out the door with the box. heh, heh, heh.
