Abstract:
Provided are coated particles and methods of their use for providing healthcare benefits. More specifically, the present invention provides amino acid and/or polymer-coated particles, or particles coated with other materials, for binding to, or otherwise associating with, surfaces of the oral cavity.

Claim (Index 1):
A coated particle comprising:\n (a) a substrate selected from the group consisting of particles or nanoparticles made from poly(lactic-co-glycolic acid) (\u201cPLGA\u201d), poly(lactic acid) (\u201cPLA\u201d), poly(cyanoacrylates) (\u201cPACA\u201d), poly(acrylic acid), poly(anhydrides), poly(amides), poly(ortho esters), poly(arginateene glycol), poly(vinyl alcohol), poly(isobutylcyanoacrylate) (\u201cPIBCA\u201d), poly(ethylene oxide) (\u201cPEO\u201d), poly(caprolactone) (\u201cPCL\u201d), cellulose, starch, chitosan, carrageenan, alginates, xantham gum, gellan gum, pectins, combinations of two or more thereof and the like, and (b) a coating comprising one or more materials selected from the group consisting of Leucine, Valine, Tryptophan, Methionine, Arginine, chitosan, xantham gum, polyvinyl pyrrolidone and derivatives thereof, Cetylpyridinium chloride, Chlorhexidine, PVM/MA Copolymers and Isopropyl, ethyl, or butyl ester of PVM/MA Copolymers, polyquaterniums, sodium carboxymethylcellulose, urethane methacylate, Dextrans, Dextrins, Merquats, Tetrahydropyrimidines, copolymers of methyl methacrylate and diethylaminoethyl methacrylate, phospholipid surfactants, poly(styrene sulfonic acid), phospholipid surfactants, ethyl lauroyl arginate HCl, and compounds of Formula I: wherein: R 1  is a linear or branched, saturated or unsaturated aliphatic group having from 5 to 22 carbon atoms; R 2  is selected from the group consisting of the free base and corresponding salt forms of the functional groups:\n \u2014NH 2 , \n said salt versions having an anion X \u2212  preferably selected from the group consisting of acetate, benzoate, besylate, bromide, chloride, chlortheophyllinate, citrate, ethandisulfonate, fumarate, gluconate, hippurate, iodide, fluoride, lactate, laurylsulfate, malate, laeate, mesylate, methysulfate, napsylate, nitrate, octadecanoate, oxalate, pamoate, phosphate, polygalacturonate, succinate, sulfate, tartrate, and tosylate; n is from 0 to 4; and R 3  is a linear or branched, saturated or unsaturated aliphatic group having from 1 to 6 carbon atoms.
