Is it ok to prepare a stock solution of CMC or HPMC
and keep them at 4*C and use them over several weeks
or they have to be prepared fresh each time and
preferably 24 h before use (adequate time for
wetting)?

It should be OK with stock solution of CMC that was prepared a few
weeks before. We did not encouter any problems with the stock in our
experience. I did not use HPMC, probably the same rule applies, but
somebody with the experience has to comment.
Hope it helps.
