Abstract
Systems for delivering cosmetic and therapeutic actives to the oral cavity employ a strip comprising a first layer of material, a second layer comprising polybutene with a molecular weight of about 300 to about 3000, and a cosmetic or therapeutic active included within the second layer. Therapeutic and cosmetic actives in compositions comprising polybutene inhibit or prevent gingivitis, caries, staining, fungi, bacteria and plaque build-up in the oral cavity by means of the delivery system.
Claims24
A delivery system for deliverying oral care active to the oral surfaces comprising:
- a) an integral carrier, and
- b) a composition comprising polybutene with a molecular weight of about 300 to about 3000 and one or more cosmetic or therapeutic actives, releasably associated to the integral carrier.
The delivery system according to claim I wherein said integral carrier is in the form of a flexible strip of material having sufficient flexibility to form a curved shape on an oral surface, said strip of material being conformable to the oral surface without permanent deformation when said delivery system is placed thereagainst and wherein said flexible strip of material comprises a first side and a second side and wherein said composition is applied to said second side of said flexible strip of material.
The delivery system according to claim I wherein the polybutene has a molecular weight of about 500 to about 2200.
A oral care product comprising:
- a) a package;
- and
- b) one or more delivery systems for delivering oral care active to the oral surfaces comprising:
- an integral carrier, and a composition comprising polybutene with a molecular weight of about 300 to about 3000 and one or more cosmetic or therapeutic actives, releasably associated to the integral carrier, disposed within said package.
A method of providing sustained release of therapeutic and cosmetic actives to oral surfaces by delivering with an integral carrier a composition comprising polybutene with a molecular weight of about 300 to about 3000, and a cosmetic or therapeutic active, to said oral surfaces.
A method of inhibiting and preventing gingivitis, caries, staining, fungi, bacteria and plaque build up in the oral cavity by delivering with an integral carrier a composition comprising polybutene with a molecular weight of about 300 to about 3000, and a cosmetic or therapeutic active, to said oral surfaces.
A method of imparting a clean feel to the dentures by delivering with an integral carrier a composition comprising polybutene with a molecular weight of about 300 to about 3000, and a cosmetic or therapeutic active, to said oral surfaces.
