Abstract
This invention provides an encapsulated co-micronized bicarbonate salt powder composition which is a blend of crystalline ingredients having a particle size between about 0.1-30 microns. 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, and then surface coating the particles with a polymer. A blend of crystalline particles such as sodium bicarbonate and zinc oxide is free-flowing and essentially free of agglomerated solids after co-micronization, and the discrete crystalline particles are coated with a polymer to form a present invention encapsulated co-micronized bicarbonate salt powder composition.
