The C6 base uses mostly chemicals that are very common to Epson 
inks.  Epson GO and C6 base are both mostly just water and glycerol.  
The surfactants are usually not specified in the OEM inks, but I 
think most are not that different than what I'm using in the various 
C6 versions.  I'm not a chemist, but my impression is that the non-
ionic surfactants I'm using are not likely to strip off a chemically 
attached coating, which is what I believe the HP pigments use.  They 
may surround it, but I think they are alcohols that just evaporate 
when the ink dries.

I do not know the recipe for Glop. I'd guess it's mostly water, 
glycol (which is in the Photo Flo in the C6 base) and glycerol, but 
with it's own mix of surfactants.  It also has a binder/coating 
material and probably some biocides for long shelf life.
