Abstract
The present invention is directed to synthetic bactericidal compositions having clay like properties and a method of using these compositions to topically treat bactenally-caused skin infections and skin diseases. The compositions within the scope of the invention compnse a bactericidal effective amount of a reducing agent, such as pyπte, marcasite, pyrrhotite, FeS2, FeS, FeS04—or other reducing agents having like properties, and a natural clay or clay mineral and/or synthetic clay or clay mineral, or other suitable matenals having clay-like properties. The synthetic bactericidal compositions are synthesized by adding the reducing agent to the clay or clay mineral. It is the presence of the reducing agent in said compositions that renders them bacteπcidal. The clays serve as a vehicle within which the reducing agent is dispersed, as a diluent to the reducing agent, and also as an adsorbent and low permeability banner in use of the composition

34. A method of determining whether a day has bactericidal properties, wherein said method comprises chemically and/or mineralogically analyzing said clay to determine the presence of a reducing agent comprising pyrite or marcasite therein or measuring the oxidation-reduction potential of a slurry containing said day.

37. A synthetic antibacterial day or day mineral, wherein said antibacterial clay or day mineral is produced by:
synthesizing a clay or day mineral or by treating or altering the chemistry of a natural clay or day mineral to yield a synthetic antibacterial day or day mineral containing within its crystal structure or within its exchange positions an antibacterial effective amount of a reducing agent;
wherein said reducing agent ferrous iron and renders said clay or day mineral antibacterial.
