There are now 3 distinct types or categories of the original C6 base.  
See http://www.paulroark.com/BW-Info/Ink-Mixing.pdf.  With each iteration, a new surfactant has been added.

Photo Flo has some glycol in it as well as the active surfactant.  This glycol component may be an important co-solvent in the mix.  My C6c mix clouds without the Photo Flo.

I don't know the ingredients of that mix.  Try to find their Material Safety Data Sheet or other source of what is in the Ilford mix.

Yes, the surfactant mix is a big part of the game.

I think of it as a commodity.  I'm using a 99.7% pure version.  

I don't know if there are differences among glycerols (aka glycerin and glycerine).
