摘要:
Oral care compositions containing a stannous salt and sodium tripolyphosphate are provided where stannous tripolyphosphate ionic intermediates comprise less than about 1% of the compositions Tetrasodium pyrophosphate, a methylvinyl ether-maleic anhydride copolymer and/or a silica oral polishing agent may be added for further efficacy. In a single phase blend, the oral care composition may be effectively limited to comprise less than about 10% water. In a dual-phase blend a mixture having the stannous salt in a first phase and the sodium tripolyphosphate in a second phase may be generated from a dual chamber storage tube (with each phase provided from a separate chamber) immediately prior to dental care usage.
摘要:
The invention includes methods of cleaning an oral surface, maintaining oral health and/or increasing oral health. Such methods encompass contacting an oral surface with a primary oral care composition at least once daily, contacting the oral surface with a periodic oral care maintenance composition at least once monthly, wherein the periodic oral care maintenance composition comprises a basic amino acid, in free or salt form and optionally contacting the oral surface with a periodic oral care cleaning composition at least once monthly. The periodic oral care cleaning compositions suitable for use in the method comprise an abrasive system.
摘要:
The invention includes an oral care composition that reduces and/or eliminates the perception of tooth sensitivity. The composition includes an adherent material and particles having an average particle size of about 8 microns or less. The particles are present in the composition in an amount of about 5% by weight. Also included within the scope of the invention are related methods, such as methods of occluding a dentin tubule.
摘要:
Oral care compositions comprising: (a) a peroxide complex comprising a peroxide component and an N-vinyl heterocyclic polymer (e.g., poly-N-vinyl polylactam, or poly-N-vinyl-polyimide); (b) a whitening agent (e.g., hydrogen peroxide); and (c) an orally acceptable carrier. In one embodiment, the carrier comprises a film forming material. Methods are also provided for making an oral care composition comprising: (a) mixing a whitening agent, silicone adhesive and carrier fluid to form a homogenous mixture; (b) adding a peroxide complex to said homogenous mixture, wherein said complex comprises hydrogen peroxide and an N-vinyl heterocyclic polymer; and (c) mixing under vacuum.
摘要:
A two component desensitizing dentifrice composition is disclosed which comprises a first dentifrice component containing an enzyme such as papain and a second dentifrice component containing an ionic surfactant such as sodium lauryl sulfate, the first and second dentifrice components being maintained separate from the other until dispensed for application to teeth whereby enzyme activity is maintained with improved dentifrice foaming characteristics.
摘要:
A composition for delivery of an oral care substance to a dental surface upon application of the composition thereto is a flexible film comprising the oral care substance dispersed in a film-forming effective amount of a polymeric matrix having a hydrophilic component, e.g., vinylpyrrolidone (VP), and a hydrophobic component, e.g., vinyl acetate (VA), in a weight ratio selected such that the film is substantially dissolvable in saliva in a period of time effective for delivery of the oral care substance. The polymeric matrix illustratively comprises a poly(VP/VA) copolymer having a VP/VA weight ratio of about 90:10 to about 10:90.
摘要:
A dual component antiplaque oral composition having superior foaming properties in which a first component contains a cationic antibacterial agent and the second component contains a anionic surfactant normally incompatible with the cationic antibacterial agent, the first and second components are simultaneously combined for application to the teeth, the first and second components being physically segregated prior to use, the components when mixed upon application to teeth providing substantially unimpaired antiplaque effect with superior foaming properties.
摘要:
A high cleaning low abrasion dentifrice containing a silica hydrogel having a mean particle size from about 5 to about 11 microns; an Einlehner hardness of from 1 to about 20; an oil absorption of about 40 to less about 100 cc/g, a BET surface area from 100 to 700 m2/g of silica, the particles having a morphology characterized by glass conchoidal fracture surfaces whereby, the dentifrice composition has a RDA of 110 to 200 and a PCR from about 150 to about 300.
摘要:
A dual component tooth whitening composition is disclosed, which composition contains a peroxide whitening and a second ingredient incompatible with the peroxide compound, the second ingredient and the peroxide compound each being incorporated in separate dentifrice components which are physically separated until dispensed for use, the components retaining their original physical state when in contact, the first component being a composition containing a peroxide whitening compound in a vehicle thickened with a combination of a particulated water insoluble inorganic compound and an organic thickener other than an alkylene oxide polymer, and the second component containing the ingredient incompatible with the peroxide.
摘要:
An aqueous dentifrice composition comprising an aqueous vehicle containing at least two active ingredients reactive with each other, at least one of the active ingredients being encapsulated in a substantially water immiscible, pressure rupturable shell which is rupturable during use of the dentifrice, causing the same to be released for interaction with the other active ingredient, the shell being formed from a plasticized alkyl cellulose polymer. The dentifrice exhibits increased efficacy for fluoridation of teeth when the active ingredients are soluble fluoride salt and a calcium salt encapsulated in the plasticized alkyl cellulose polymer.
