  • Publication number: 20130344120
    Abstract: Disclosed are oral care mouth rinse compositions formulated as stable oil-in-water emulsions comprising: (a) at least about 0.025% by weight of a quaternary ammonium antimicrobial agent, (b) at least about 0.05% by weight of an essentially water-insoluble volatile oil, and (c) at least about 50% by weight water, wherein the emulsion comprises oil droplets having an average mean particle size of about 350 nm or less. Examples of quaternary ammonium antimicrobial agent include cetylpyridinium chloride (CPC), tetradecylpyridinium chloride, N-tetradecyl-4-ethyl pyridinium chloride or domiphen bromide.

  • Publication number: 20110239736
    Abstract: Disclosed are oral care compositions effective to control mouth and breath malodour comprising in a pharmaceutically acceptable carrier, a combination of an antibacterial agent and a deodorizing or odor-neutralizing agent comprising a compound having the structure wherein R1, R2, R3, and R5 may be identical or different, each representing H, a linear or branched C1-C6 alkyl or alkenyl, phenyl, —OH or —ORa; R4 is —OH, —ORa, phenyl, or a linear or branched C1-C6 alkyl or alkenyl; and Ra is phenyl or a linear or branched C1-C6 alkyl or alkenyl. The odor-neutralizing agent may further comprise one or more of an additional odor-neutralizing compound selected from ?-damascenone, ?-isomethylionone, ?-ionone, ?-ionone, pulegone, piperitone, carvone, coenzyme Q10 or cinnamaldehyde.

  • Patent number: 8007771
    Abstract: The present invention relates to oral care compositions comprising stannous ions, a mint-type flavor oil, a protectant component that prevents generation of off odor and off taste in the composition, and orally acceptable carriers. The mint-type oils include peppermint, spearmint and corn mint. Suitable protectant components include copper salts and carbonyl compounds such as ascorbic acid; cis-jasmone; 2,5-dimethyl-4-hydroxy-3(2H)-furanone; 5-ethyl-3-hydroxy-4-methyl-2(5H)-furanone; vanillin; ethyl vanillin; anisaldehyde; 3,4-methylenedioxybenzaldehyde; 3,4-dimethoxybenzaldehyde; 4-hydroxybenzaldehyde; 2-methyoxybenzaldehyde; 4-methoxybenzaldehyde; benzaldehyde; cinnamaldehyde (3-phenyl-2-propenal); hexyl cinnamaldehyde; ?-methyl cinnamaldehyde; ortho-methoxy cinnamaldehyde; ?-amyl cinnamaldehyde; and combinations thereof. The oral care composition may be a dentifrice.

  • Publication number: 20080175801
    Abstract: The present invention relates to stable personal care composition, including oral care compositions containing a peroxide source. The compositions are stabilized by eliminating or minimizing the presence in the composition of metals having radical forming potential with the peroxide. Preferably, the metals that are eliminated or reduced are cobalt, copper, palladium, nickel and iron. The compositions are further stabilized by the addition of agents having scavenging or quenching activity for free radicals. Reducing free radical activity in the product matrix prevents radical-mediated loss and degradation of peroxide and other ingredients, in particular organic compounds added as active or aesthetic agents, including flavors, perfumes, colorants and thickeners. Provided are peroxide containing oral care products with enhanced consumer appeal in terms of taste, mouthfeel and appearance, thereby encouraging compliance and regular use.

  • Publication number: 20080008729
    Abstract: The present invention relates to flavor oils including mint-, fruit- and spice-type flavors that are specially processed to substantially eliminate low-molecular weight sulfur compounds, in particular dimethyl sulfoxide (DMSO), which has been found to be the main precursor of malodorous species such as dimethyl sulfide and methyl mercaptan. These malodorous species are produced via oxidation-reduction reactions involving such sulfur-containing compounds present in flavor oils. A preferred processing method is an aqueous-washing process, which has advantages of being simple, inexpensive and easy to implement while importantly avoiding the problems of typical processes including non-selective removal of desirable components and subjecting the flavor oils to extreme conditions that may destroy other components and result in undesirable changes in flavor or odor character.
