Polycationic polymeric antimicrobial surfactant and polymeric biocompatible antimicrobial surfactant compositions are useful in dispersing various compounds in a carrier liquid. The polycationic polymeric antimicrobial surfactant and polymeric biocompatible antimicrobial surfactant compositions employ polymers having both hydrophilic domains and hydrophobic domains so that the compositions can disperse particles such as polymer particles or droplets in a continuous phase as well as provide stable dispersions that have not been provided before. The antimicrobial properties of the compositions provide much-needed capabilities of fighting infectious agents such as bacteria and viruses in a wide spectrum of products such as paint, adhesives, and coatings. Methods of using these compositions as well as methods of making products using the compositions are disclosed.
A method of creating a dispersion, wherein the method comprises dispersing an insoluble compound in a continuous phase with a polycationic polymeric antimicrobial surfactant, wherein the polycationic polymeric antimicrobial surfactant comprises a polymer having a number of nonionic hydrophilic monomers and a number of cationic antimicrobial monomers, each comprising a vinyl pyridine quaternized with an alkyl group, and wherein the surfactant has a sufficient number of the nonionic hydrophilic monomers present in the polymer to provide a hydrophilic domain, a sufficient number of the cationic antimicrobial monomers and vinylic groups from the nonionic hydrophilic monomers present in the polymer to provide a hydrophobic domain, and the number of the cationic antimicrobial monomers present is sufficient to provide at least three cations in the polymer:
A dispersion comprising a polycationic polymeric antimicrobial surfactant, a continuous liquid phase, and particles of a second polymer associated, with the polycationic polymeric antimicrobial surfactant, wherein the dispersion comprises a suspension or a colloid and wherein the polycationic polymeric antimicrobial surfactant comprises a polymer having a nonionic hydrophilic monomer and a cationic antimicrobial monomer comprising a vinyl pyridine quaternized with an alkyl group and having a sufficient number of nonionic hydrophilic monomers present in the polymer to provide a hydrophilic domain, a sufficient number of cationic antimicrobial monomers and vinylic groups from nonionic hydrophilic monomers present in the polymer to provide a hydrophobic domain, and the number of cationic monomers present is sufficient to provide at least three cations in the polymer.
