Claims33
A method of antimicrobially treating a food article, comprising contacting the food article with an effective amount of a water stable composition comprising water and a product that is formed by reacting in water:
- a) an organosilane of the formula RnSiX4−n where n is an integer of from 0 to 3;
- each R is, independently, a nonhydrolizable organic group;
- and each X is, independently, a hydrolyzable group, with
- b) a polyol containing at least three hydroxy groups, wherein all of the hydroxy groups are separated by at least three intervening atoms,
- wherein the polyol is not hydroxyethyl cellulose,
- wherein the product is a monomer, oligomer, or a combination thereof,
- for a period of time sufficient to antimicrobially treat the food article.
A method of antimicrobially coating a fluid container used for containing a human or animal consumable product, comprising contacting the container with an effective amount of a water stable composition comprising water and a product that is formed by reacting in water:
- a) an organosilane of the formula RnSiX4−n where n is an integer of from 0 to 3;
- each R is, independently, a nonhydrolizable organic group;
- and each X is, independently, a hydrolyzable group, with
- b) a polyol containing at least three hydroxy groups, wherein all of the hydroxy groups are separated by at least three intervening atoms,
- wherein the polyol is not hydroxyethyl cellulose,
- wherein the product is a monomer, oligomer, or a combination thereof,
- for a period of time sufficient to antimicrobially coat the container.
A method of antimicrobially coating a latex medical article for use in a human or animal medical procedure, comprising contacting the article with an effective amount of a water stable composition comprising water and a product that is formed by reacting in water:
- a) an organosilane of the formula RnSiX4−n where n is an integer of from 0 to 3;
- each R is, independently, a nonhydrolizable organic group;
- and each X is, independently, a hydrolyzable group, with
- b) a polyol containing at least three hydroxy groups, wherein all of the hydroxy groups are separated by at least three intervening atoms,
- wherein the polyol is not hydroxyethyl cellulose,
- wherein the product is a monomer, oligomer, or a combination thereof,
- for a period of time sufficient to antimicrobially coat the article.
A method of antimicrobially enhancing a product of rubbing alcohol, a flower preservative, or a waterproofing solution, comprising admixing with the product an effective amount of a water stable composition comprising water and a product that is formed by reacting in water:
- a) an organosilane of the formula RnSiX4−n where n is an integer of from 0 to 3;
- each R is, independently, a nonhydrolizable organic group;
- and each X is, independently, a hydrolyzable group, with
- b) a polyol containing at least three hydroxy groups, wherein all of the hydroxy groups are separated by at least three intervening atoms,
- wherein the polyol is not hydroxyethyl cellulose,
- wherein the product is a monomer, oligomer, or a combination thereof,
- for a period of time sufficient to antimicrobially enhance the product.
A method of antimicrobially treating a substrate selected from the group consisting of a concrete pipe, a tooth brush, a comb, a hair brush, a denture, an orthodontic retainer, a spa or pool filter, an air filter, an HVAC air system, a cabin air system, a marble article, a statue, an exposed work of art, an HDP plastic cover, a stucco finish, blended cotton, a bio-film, a bio-adhesive, a single ply roofing, a roofing shingle, and a fiberglass reinforcement product, comprising contacting the substrate with an effective amount of a water stable composition comprising water and a product that is formed by reacting in water:
- a) an organosilane of the formula RnSiX4−n where n is an integer of from 0 to 3;
- each R is, independently, a nonhydrolizable organic group;
- and each X is, independently, a hydrolyzable group, with
- b) a polyol containing at least three hydroxy groups, wherein all of the hydroxy groups are separated by at least three intervening atoms,
- wherein the polyol is not hydroxyethyl cellulose,
- wherein the product is a monomer, oligomer, or a combination thereof,
- for a period of time sufficient to antimicrobially treat the substrate.
