Tyler,

You're right! Inks contain all sorts of stuff that most people don't think 
about or understand:-

Dye or pigment,

Solvent (eg water, alcohol, methyl ethyl ketone)

Surfactant (eg tergitol)

Penetrant (eg isopropyl alcohol)

Solubilizing agent (eg methyl pyrollidone)

Dispersant (eg derussol carbon black)

Humectant (eg glycol)

Viscosity modifier (eg glycol)

pH buffer (eg triethylamine)

Chelating agent (eg EDTA)

Biocide (eg benzisothiazolin-3-one)

UV-blockers

Antioxidants

Free radical inhibitors

I just figure there's a lot of ingredients in these inksets we know
nothing about that could have an impact. There has to be many
components that are not actually image forming, but simply allow the
inks to perform, deliver, sit well, ship well, taste good, etc..
Those have to have some impact on longevity, chemical robustness,
etc.. I have no idea what I'm talking about here.
