1. An antimicrobial composition, comprising:
- perlite coated with a composition comprising approximately 4% by weight an organosilane quaternary ammonium compound and approximately 2% by weight a quaternary ammonium compound,wherein the quaternary ammonium compound is not an organosilane quaternary ammonium compound;
wherein the organosilane quaternary ammonium compound is 3-trimethoxysilyl propyltetradecyldimethyl ammonium chloride; and
wherein the quaternary ammonium compound is a mixture of alkyl (C12, C14 and C16) dimethyl benzyl ammonium chloride, octyl decyl dimethyl ammonium chloride, dioctyl dimethyl ammonium chloride and didecyl dimethyl ammonium chloride.

6. A method of rendering perlite antimicrobial comprising:
-
contacting perlite with an aqueous composition, wherein the aqueous composition comprises approximately 4% by weight of an organosilane quaternary ammonium compound and approximately 2% by weight of a quaternary ammonium compound, and wherein the quaternary ammonium compound is not an organosilane quaternary ammonium compound; and bonding at least a portion of the aqueous composition to at least a portion of the perlite to form an antimicrobial coating on the perlit, wherein the organosilane quaternary ammonium compound is 3-trimethoxysilyl propyltetradecyldimethyl ammonium chloride; and wherein the quaternary ammonium compound is a mixture of alkyl (C12, C14 and C16) dimethyl benzyl ammonium chloride, octyl decyl dimethyl ammonium chloride, dioctyl dimethyl ammonium chloride and didecyl dimethyl ammonium chloride. - View Dependent Claims (7, 8, 9, 10)

11. A method of removing a portion of microbes present in a gas, liquid or solid, comprising:
-
contacting the gas, liquid or solid with a composition having antimicrobial activity, the composition having antimicrobial activity comprising perlite coated by an aqueous composition comprising approximately 4% by weight of an organosilane quaternary ammonium compound and approximately 2% by weight of a quaternary ammonium compound, wherein the quaternary ammonium compound is not an organosilane quaternary ammonium compound; wherein the organosilane quaternary ammonium compound is 3-trimethoxysilyl propyltetradecyldimethyl ammonium chloride; and wherein the quaternary ammonium compound is a mixture of alkyl (C12, C14 and C16) dimethyl benzyl ammonium chloride, octyl decyl dimethyl ammonium chloride, dioctyl dimethyl ammonium chloride and didecyl dimethyl ammonium chloride. - View Dependent Claims (12)
