ABSTRACT:
This invention provides a co-micronized bicarbonate salt composition which is a blend of ingredients having a particle size between about 0.01-1.0 micron. The composition is produced by mill co-micronization of a crystalline bicarbonate ingredient and a crystalline inorganic compound ingredient having a Mohs hardness value between about 3-7. A co-micronized blend such as sodium bicarbonate and zinc oxide is free-flowing and essentially free of agglomerated particles.
