Those lists are not the complete formulas either. They both contain a Phenidone derivative, and I believe Ilfosol also contains ascorbic acid. Sodium sulfite isn't listed here either. It is difficult to compare the formulations, and especially the working properties of proprietary formulas using MSDS information. The approximate formula for HC-110 is known (although Kodak has tinkered with it over time).
Ilfotec HC is a lot more similar in my mind. Ilfosol is more like liquid concentrate XTOL.

A bunch of Nikons; Feds, Zorkis and a Kiev; Pentax 67-II (inherited from my deceased father-in-law); Bronica SQ-A; and a nice Shen Hao 4x5 field camera with 3 decent lenses that needs to be taken outside more. Oh, and as of mid-2012, one of those bodies we don't talk about here.
