1. A dispersion comprising
an emulsion in a continuous liquid phase, wherein the emulsion consists essentially of
a polycationic polymeric antimicrobial surfactant, and
particles of a second polymer associated with the polycationic polymeric antimicrobial surfactant,
wherein the polycationic polymeric antimicrobial surfactant comprises a polymer consisting essentially of
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 antimicrobial monomers present is sufficient to provide at least three cations in the polymer, and wherein
the nonionic hydrophilic monomer comprises at least one of poly(ethylene glycol) methacrylate (poly(ethyleneglycol methacrylate)) and poly(ethylene glycol) methyl ether methacrylate (poly(ethyleneglycol methylether methacrylate)), and
the vinyl pyridine comprises 4-vinyl pyridine.
