Non indicating silica gels will adsorb moisture in exactly the same way as indicating Blue silica gel, but they will Not indicate when they are becoming saturated by changing their color. It will remain white when they are becoming saturated. This is useful in fillers, catalysts supports, adsorbent, dehydrating agent and as the buffing media in toothpaste.
