It should work. The alcohol is used to thin the
glycerine which is pretty thick by itself. Also, I
have, on occassion, had paste that thinned ok with
just the glycerine and did not need alcohol. If you
are using hot air to melt the solder paste, you may
want to go with straight glycerine. The blowing hot
air will seperate the alcohol from the glycerine
(Alcohol is lighter) and it will bubble (Which is what
you experienced, at least I think...) 

I do have one thought regarding ethanol. Typically,
ethanol comes in many qualitative grades as opposed to
isopropyl with is available in a medical grade at drug
stores in the usa. Just be sure the ethanol is of a
decent grade and not watered down below 70% with h20.
