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 py?te, 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 bacte?cidal.
