Antibacterial antiplaque oral composition
First Claim
1. An oral composition dentifrice for attaching, adhering or bonding a plaque-inhibiting antibacterial agent to oral tooth and gum surfaces comprising in an orally acceptable aqueous humectant vehicle, about 5-30% by weight of a siliceous polishing agent, an effective antiplaque amount in the range of about 0.01-5% by weight of a water soluble or swellable antibacterial-enhancing agent having an average molecular weight of about 100 to about 1,000,000, which contains at least one carboxylic delivery-enhancing functional group and at least one organic retention-enhancing functional group, which delivery-enhancing group enhances delivery of said antibacterial agent to oral tooth and gum surfaces and which retention-enhancing group enhances attachment, adherence or bonding of said antibacterial agent on oral tooth and gum surfaces, and about 0.5-50% by weight of a solubilizing material for said antibacterial agent in amount sufficient to dissolve said antibacterial agent in saliva and permit delivery of said antibacterial agent to soft oral tissues at or near the gum line, wherein (a) said oral composition dentifrice is free of polyphosphate anticalculus agent in an effective anticalculus amount and (b) said oral composition dentifrice does not contain polyethylene glycol which effectively inhibits the antibacterial activity of said non-cationic antibacterial agent.

Abstract
An oral composition dentifrice comprising an orally acceptable vehicle, about 5-30% by weight of a siliceous polishing agent, a substantially water-insoluble noncationic antibacterial antiplaque agent, such as 2,4,4'"'"'-trichloro-2'"'"'-hydroxydiphenyl ether (triclosan), and an antibacterial-enhancing agent which enhances the delivery of said antibacterial agent to, and retention thereof on, oral surfaces, wherein said antiplaque agent is substantially completely dissolved in saliva present during tooth and gum cleaning in a solubilizing agent therefor. The solubilizing agent may be a humectant polyol such as propylene glycol, dipropylene glycol and hexylene glycol; a cellosolve such as methy cellosolve and ethyl cellosolve; a vegetable oil or wax containing at least about 12 carbon atoms in a straight chain such as olive oil, castor oil and petrolatum; or an ester such as ethyl acetate, amyl acetate, glyceryl tristearate and benzyl benzoate.

- 1. An oral composition dentifrice for attaching, adhering or bonding a plaque-inhibiting antibacterial agent to oral tooth and gum surfaces comprising in an orally acceptable aqueous humectant vehicle, about 5-30% by weight of a siliceous polishing agent, an effective antiplaque amount in the range of about 0.01-5% by weight of a water soluble or swellable antibacterial-enhancing agent having an average molecular weight of about 100 to about 1,000,000, which contains at least one carboxylic delivery-enhancing functional group and at least one organic retention-enhancing functional group, which delivery-enhancing group enhances delivery of said antibacterial agent to oral tooth and gum surfaces and which retention-enhancing group enhances attachment, adherence or bonding of said antibacterial agent on oral tooth and gum surfaces, and about 0.5-50% by weight of a solubilizing material for said antibacterial agent in amount sufficient to dissolve said antibacterial agent in saliva and permit delivery of said antibacterial agent to soft oral tissues at or near the gum line, wherein (a) said oral composition dentifrice is free of polyphosphate anticalculus agent in an effective anticalculus amount and (b) said oral composition dentifrice does not contain polyethylene glycol which effectively inhibits the antibacterial activity of said non-cationic antibacterial agent.
- 2. An oral composition dentifrice for attaching, adhering or bonding a plaque-inhibiting antibacterial agent to oral tooth and gum surfaces comprising an orally acceptable aqueous humectant vehicle, about 5-30% by weight of a siliceous polishing agent, an effective amount in the range of 0.01-5% by weight of a substantially water insoluble non-cationic antibacterial agent, an effective amount in the range of about 0.05-5% by weight of an anionic copolymer of maleic acid or anhydride with another ethylenically unsaturated polymerizable monomer, which copolymer enhances delivery and attachment, adherence or bonding of said antibacterial agent on oral tooth and gum surfaces, and about 0.5-50% by weight of a solubilizing material for aid antibacterial agent in amount sufficient to dissolve said antibacterial agent in saliva and permit delivery of said antibacterial agent to soft oral tissues at or near the gum line, wherein (a) said oral composition dentifrice is free of polyphosphate anticalculus agent in an effective anticalculus amount and (b) said oral composition dentifrice does not contain polyethylene glycol which effectively inhibits the oral antibacterial activity or said non-cationic antibacterial agent.

16. An oral composition dentifrice comprising in an orally acceptable aqueous humectant vehicle, about 5-30% of a siliceous polishing agent, about 0.01-5% of triclosan, about 0.05-5% of a copolymer of maleic acid or anhydride with methyl vinyl ether, and propylene glycol in amount sufficient to dissolve the triclosan in saliva.
