Oral care compositions
The application relates to oral care compositions comprising substantive polyesters formed from xylitol, polycarboxylic acids (or esters, acid halides or anhydrides thereof) and optionally arginine. The formed polyesters or polyesteramides are active in biofilm inhibition and dissolution to maintain clean teeth.
1. An oral care composition comprising:
a polymer formed from the condensation of only xylitol and
carboxymethylcellulose or anhydrides, esters or acid halides thereof,
wherein the formed polymer is distributed in an orally acceptable carrier.
2. The oral care composition according to claim 1 , wherein the carboxymethylcellulose has a degree of acid substitution ranging from about 0.1 to about 3.
3. The oral care composition according to claim 1 , wherein the formed polymer consists of one or more xylitol-grafted carboxymethylcellulose polymers selected from the group consisting of formula (I), (I′) and (I″),
wherein CMC is a carboxymethylcellulose radical.
4. The oral care composition according to claim 2 , wherein the degree of acid substitution ranges from about 0.5 to about 2.0.
5. The oral care composition according to claim 1 , wherein xylitol makes up from about 3 to about 80 wt. % based on the total weight of the formed polymer.
6. The oral care composition according to claim 1 , wherein the formed polymer has a Mw ranging from about 500 to about 1,000,000.
7. The oral care composition according to claim 1 , comprising at least one ingredient selected from the group consisting of surfactants, desensitizing agents, chelating agents, whitening agents, tartar control agents, antibacterial agents, abrasives, binders, thickening agents, detergents, adhesion agents, foam modulators, pH modifying agents, mouth-feel agents, sweeteners, flavoring agents, colorants, preservatives and combinations thereof.
8. The oral care composition according to claim 7 , wherein the ingredient is an antibacterial agent selected from the group consisting of triclosan, chlorhexidine or its salts, peroxides, phenols or their salts, domiphen bromide (phenododecinium bromide), bromochlorophene, Zn salts, chlorophylls, Cu salts, Cu gluconate, Cu chlorophyll, sodium lauryl sulfate, quaternary monoammonium salts, pyridinium salts, polylysine, homopolymers of argininine, salts or complexes of arginine, stannous fluoride, thymol, menthol, methyl salicylate, eucalyptol and combinations thereof.
9. The oral care composition according to claim 8 , wherein the antibacterial agent is selected from the group consisting of quaternary monoammonium salts, pyridinium salts, polylysine, triclosan, chlorhexidine or its salts and combinations thereof.
10. The oral care composition according to claim 1 , wherein the formed polymer makes up about 0.01 to about 95 wt. %, based on the total weight of the oral care composition.
11. The oral care composition according to claim 1 , wherein the composition is a product selected from the group consisting of orally dissolvable films, whitening strips, mouthwashes, tooth pastes, dentifrices, oral lozenges, chewing gums and dental flosses.
