First Claim
1. A composition comprising an organosilane and an acidic stabilizing solution;
- wherein the organosilane is of the formula RnSiX4-n, where n is an integer from 0 to 3, each R is, independently, a non-hydrolyzable organic group, and each X is, independently, a hydrolyzable group; and
wherein the acid stabilizing solution comprises at least one inorganic acid, at least one glycol ether comprising diethylene glycol butyl ether, and at least one cationic surfactant in water, wherein the cationic surfactant is a quaternary ammonium salt having the following structure;
wherein each of R38, R39, R40, and R41 are independently selected from the group consisting of alkyl, aryl, and arylalkyl, or the nitrogen may be part of a ring system; and
wherein X is an anion.

Abstract
The present invention relates to water-stable compositions and compounds formed by mixing an organosilane, optionally having a non-hydrolyzable organic group, but having one or more hydrolyzable groups, and an acidified stabilizing solution prepared from at least one acid, at least one glycol ether, and at least one cationic surfactant, preferably at least one quaternary ammonium salt (QAS), in water. The present invention also relates to methods of treating a substrate by mixing or contacting the substrate with the product, compound, or composition of this invention for a period of time sufficient for treatment of the substrate, methods of antimicrobially treating a food article, methods of antimicrobially coating a fluid container, methods of dyeing and treating a substrate, and methods of antimicrobially coating a latex medical article. The invention also pertains to a treated substrate having adhered thereto the product, compound, or composition of this invention.
