Abstract: A polymeric biocidal salt is prepared from two components. The first component comprises a biocidal anionic or cationic monomeric, dendrimeric or polymeric ion. The second component comprises a dendrimeric or polymeric anion or cation having insignificant biocidal activity and a number average molecular weight of at least about 500. The second component will be cationic in nature when the first component is anionic in nature and anionic in nature when the first component is cationic in nature. The salt is further characterized as partially dissolving when exposed to an aqueous medium, thereby: (a) releasing sufficient biocidal ion to exceed the MIC or MBIC of a target bacteria sought to be controlled; and (b) leaving a reservoir of undissolved salt capable of being further dissolved and releasing additional biocidal ion as the biocidal ion is consumed or is otherwise removed from the environment encompassing the target bacteria.

Abstract: A method for cleaning, benefiting, or deodorizing skin or hair utilizing a body wash, skin cleaner, soap, shampoo or deodorizer formulation containing a controlled release skin benefit or deodorizing salt, a hydrophilic moisturizing polymer and surfactants is described.

Abstract: This invention pertains to dental care compositions with antimicrobial benefits. In particular, the invention provides for compositions of oral tissue-adherent salts that release biocidal ions on a controlled release basis and thereby provide and maintain an essentially uniform concentration of biocidal ions above the MBC or MIC of the target bacteria at the site of application in the mouth for an extended period of time. The compositions are useful for treating or preventing oral diseases resulting from bacteria, fungal or yeast infections, such as caries, gingivitis, periodontal disease and candidiasis.

The salt is characterized such that when the salt is exposed to an aqueous medium, the salt partially dissolves thereby releasing biocidal ions in an amount sufficient to exceed the MIC or MBC of a target bacteria being controlled, and further characterized as leaving a residual reservoir of undissolved salt capable of releasing more biocidal ions as the salt is consumed or otherwise removed from the environment encompassing the target bacteria. The preferred cationic biocidal molecule comprises N?-lauroyl-L-arginine ethyl ester (“LAE”).
