Abstract
An oral care composition is provided. The composition comprises (a) a first component comprising an amine fluoride; and (b) a second component comprising an acidic polymer; wherein the amine fluoride and acidic polymer have respective first and second reactive groups which are arranged to react together to form a cross-linked copolymer of the amine fluoride and acidic polymer when the composition is applied to an oral cavity.
Claims29
An oral care composition, comprising:
- (a) a first component comprising an amine fluoride;
- and
- (b) a second component comprising an acidic polymer;
- wherein the amine fluoride and acidic polymer have respective first and second reactive groups which are arranged to react together to form a cross-linked copolymer of the amine fluoride and acidic polymer when the composition is applied to an oral cavity, and wherein the amine fluoride and the acidic polymer are maintained separately from one another in the oral care composition prior to contacting with the oral surface;
- wherein the amine fluoride is N,N,N′-tris(2-hydroxyethyl)-N′-octadecylpropane-1,3-diamine dihydrofluoride and wherein the acidic polymer is a copolymer of maleic acid or maleic anhydride with methyl vinyl ether.
A method of treating or preventing a disease or condition of the oral cavity, comprising the steps of:
- (a) contacting an oral surface with a first component, of an oral care composition, comprising an amine fluoride;
- and subsequently
- (b) contacting the oral surface with a second component, of an oral care composition, comprising an acidic polymer;
- wherein the film-forming amine fluoride and film-forming acidic polymer have respective first and second reactive groups which are arranged to react together to form a cross-linked copolymer of the amine fluoride and acidic polymer on the oral surface, wherein the cross-linked copolymer is a film-former, and wherein the amine fluoride and the acidic polymer are maintained separately from one another prior to contacting with the oral surface;
- wherein the amine fluoride comprises hydroxyalkyl groups as the first reactive groups;
- wherein amine fluoride is N,N,N′-tris(2-hydroxyethyl)-N′-octadecylpropane-1,3-diamine dihydrofluoride, and wherein the acidic polymer is a copolymer of maleic acid or maleic anhydride with methyl vinyl ether.
A method of protecting a tooth surface against acid attack, comprising the steps of:
- (a) contacting the tooth surface with a first component, of an oral care composition, comprising an amine fluoride;
- and subsequently
- (b) contacting the tooth surface with a second component, of an oral care composition, comprising an acidic polymer;
- wherein the film-forming amine fluoride and film-forming acidic polymer have respective first and second reactive groups which are arranged to react together to form a cross-linked copolymer of the amine fluoride and acidic polymer on the tooth surface, wherein the cross-linked copolymer is a film-former, and wherein the amine fluoride and the acidic polymer are maintained separately from one another prior to contacting with the tooth surface;
- wherein the amine fluoride comprises hydroxyalkyl groups as the first reactive groups;
- wherein amine fluoride is N,N,N′-tris(2-hydroxyethyl)-N′-octadecylpropane-1,3-diamine dihydrofluoride and wherein the acidic polymer is a copolymer of maleic acid or maleic anhydride with methyl vinyl ether.
