METHODS FOR FORMING STABILIZED METAL SALT PARTICLES

A process comprising: a) forming a first solution comprising at least one salt precursor; b) forming a second solution comprising a complex formed from at least one metal agent and at least one dispersing agent in a particle size stabilizing effective amount; c) adding said second solution to said first solution at a rate sufficient to maintain a clear solution throughout addition and to form a product solution comprising stabilized metal salt particle having a mean particler size of less than about 200 nm; d) drying said product solution to form an antimicrobial metal salt powder comprising 0.01 to about 10 weight % metal in the antimicrobial metal salt powder.
