A good formula for an EEG gel

In This solution The reaction occurs between boric acid and glycerin for the formation of Given this happens at room temperature this asks for more time so that it takes some time before your gel runs out. NaCMC carries acid carboxyl groups, which are not so strongly sour. This may be different from   tragacanth.   Tragacanth becomes as an anionic polymer with the following components arabinose, xylose, fucose, galactose and acid acid. So there is effectively an acidic component. But if it is not geionized, the effect on the viscosity will probably be smaller as with CMC.

So CMC-is converted to the non-geionized form and then maybe still salted by by the not insignificant amount of NaCl. I would replace NaCMC with a non-charged polymer like hydroxyethylcellulose medium viscosity also 50 g (?). In add parts and follow viscosity.  

I read for hydroxyethylcellulose

Soluble in most 10% salt solutions and in many 50% (or saturated) salt solutions such as   sodium chloride   and aluminum nitrate
