The reason for the use of hexamine is that it dramatically increases the size of the flame envelope. Thus it has two functions, to increase the size of the light source and to reduce the temperature as the heat is spread over a larger volume.
It does work, my best blue to date had hexamine in it.
Would you mind sharing the forumula? Pleeeeeease?!

so hexamine definitely attracts moisture!
There's been some discussion over on Passfire recently on substituting Lactose for Hexamine for just this reason, with purportedly good results. I'd be very interested to hear more on the equivalence ratios etc. if anyone has tried this...

I suspect that's a valuable commercial secret for now

They are OK, but the flame envelope is small, and they are easy to blow out. You do need to seriously step prime them if you want a decent break.
There is a coated grade of hexamine that is available which is not so much of a problem from a point of view of turning into a puddle of water.
As a hint just add a couple of percent of hexamine to your favourite formula (checking for incompatibilities) and see the difference.
