Synthetic Antibacterial Clay Compositions And Method Of Using Same

US Patent:
2013000, Jan 3, 2013
Filed:
Jun 1, 2010
Appl. No.:
13/515309
Inventors:
David W. Metge - Lafayette CO, US
Lynda Williams - Tempe AZ, US
Dennis D. Eberl - Boulder CO, US
Alex E. Blum - Boulder CO, US
Ronald W. Harvey - Boulder CO, US
International Classification:
A61K 33/26, C12Q 1/18, A61P 31/04, A61K 9/14
US Classification:
424400, 424646, 435 32
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
