The active ingredient in the absorbent feminine napkins is the same stuff as in Pampers and other disposable diapers including Depends. One of the polyacrylate crystals, i think. Great at absorbing liquid water, but not much at absorbing water vapor, compared to silica gel. Silica gel is also reusable; just dry it in the oven for an hour at 250 degrees or so.
If you really want super duper extra dry air, you need a refrigerated dryer. Liquid nitrogen works a treat.
