easiest & most friendly buffer to play with, C6H8O7 or H3PO4 ?
hi,
i am messing with Na2CO3 water to shave and i am irritating my face for a few days now.
so i i consider buffering my causitc water.
i think that C6H8O7 or H3PO4 should work well without producing unfriendly by-products.
what should be the easiest to work with?
thanks

If you are irritating your face I suspect you are using too much Na2CO3.

I think that both should be without much problems. Acetic acid could be another option. Then you can use simple white vinegar.

Use a carbonate-bicarbonate buffer system?  You can't store it for long
(aqueous), but if freshly prepared, it works. You might be able to store a mix of the carbonate and bicarbonate dry, then just add water to a little
immediately before use. Keep in a tightly closed jar.

considering i will have to heat my water at around 80 deg Cel., won't NaHCO turn into Na2CO3 immediately?

Use bicarb alone, boil the water for several minutes to drive off excess CO2, then let cool slowly to the desired temperature, which allows calcium
and magnesium carbonates to settle.
Or get a water softening unit.

Seriously, though. Wouldn't these questions be better suited to a shaving forum?

May I recommend a shaving stick and avoiding multi-blade razors? I have a very vigorous beard, and shaving foam just doesn't cut it.
Not to mention the economy of paying $3 for enough shave stick to last for months!
