Abstract
The present invention comprises methods and compositions for treating solid surfaces having antimicrobial and biocidal properties. Such surfaces are capable of controlling or killing a broad spectrum of biological agents, including viruses, bacteria and other microbial agents in solids, liquids or gases that subsequently contact the treated surface.
Claims12
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.
2 more elements
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.
3 more elements
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.
