That is what I made it for.  (But one does not dissolve pigments, the issue
is keeping them in suspension.)

What I did was see what chemicals were used in the OEM inks.  I wanted to
avoid incompatibilities.  So, with water and glycerin/glycerol being prime
ingredients, I figures this would do it.  The Epson base has some other
proprietary chemicals in it, but if the dilution is not too much -- say up
to 50% -- there should be enough of the others (wetting agents,
anti-bacterial agents, etc.) to continue to do their jobs adequately.

So, in my experiments, the mix above seems to work fine.  I have no real
long term experience with it.  In my fade tests with B&W inksets made with
Epson pigments, the MIS pigments did better.
