The rheological behaviour of the composition of the invention corresponds well with the characteristic rheological behaviour of typical aqueous dentifrice formulations

WO10076123A2: The present invention relates to a dentifrice composition comprising Polyethyleneglycol that is capable of providing relatively high warming effect during brushing while keeping the composition stable and does not allow it to solidify below sub-zero temperatures; and allowing the water-soluble actives present in the composition solubilised. The composition includes a selective combination of 50 to 65 weight percent Polyethyleneglycol (or a derivative thereof), 2.5 to 15 weight percent Glycerine and 5 to 7 weight percent water

WO08138660A1: A packed toothpaste, the toothpaste comprising capsules dispersed therein, the capsules comprising a sensory agent and/or reactive agent, the package comprising a dispensing (3) means which is closed by a flip-top cap (4). 

WO08006725A1:  An opaque toothpaste composition comprising: water; a zinc salt; a chelating agent for the zinc salt, the chelating agent having a log Ks1 as herein defined of from 3.0 to 7.0; calcium carbonate at from 10 percent to 70 percent by weight of the toothpaste composition; a monofluorophosphate salt; and trisodium phosphate.  

WO07122146A1:   A toothpaste composition comprising an abrasive calcium compound, a fluoride salt, alkali metal silicate and a salt selected from the class comprising alkali metal citrates.  

US2009010857A:  Toothpaste and method for making such, the toothpaste comprising calcium carbonate as abrasive, water and zinc salt substantially all of which is in the form of water-solubilised zinc citrate.

US2008159966A: Multiphase toothpaste composition comprising a first phase disposed co-axially within a second phase, each of the phases having a viscosity of from 180 000 to 250 000 mPa.s.  

US2003072721A: Oral composition comprising from 1 to 60 percent by weight of the total composition fine ground natural chalk (FGNC), characterised in that the FGNC comprises particulate matter of weight-based median particle size ranging from 1 to 15 mum and BET surface area ranging from 0.5 to 3 m2/g

US2003215403A: An oral composition with an improved teeth whitening effect, comprising a first formulation comprising an effective amount of a peroxy amido phthalamide having the structural formula: in which R is hydrogen or C1-C4 alkyl; n is 1 to 5; and X is C=O or SO2, wherein said first formulation has a pH of from 2 to 6 and a second formulation formulated such that when said second formulation is mixed with the first formulation the pH of the mixture is from 6.5 to 8.5.

US2002122776A:  The present invention relates to oral care compositions with an improved teeth whitening effect. This effect is achieved by inclusion in the oral care compositions of certain organic peroxy acids as teeth whitening/bleaching agents, particularly peroxyamidophthalamides together with hydrogen peroxide.

US2002034478A:  Oral non-food composition comprising an active agent which is substantially insoluble in water at room temperature and pressure and a silicone with a viscosity within the range 10x10-3 to 90x10-3 m2s-1 at 25 degrees centigrade, said composition obtainable by mixing said active agent and silicone before adding said mixture to the remaining ingredients of the composition.

US2002012635A: Oral composition comprises a first formulation stored adjacent a second formulation for simultaneous dispensing, wherein the pH the first formulation differs from the pH of the second formulation by at least one pH unit.

WO0010520A1: The present invention relates to a toothpaste which comprises particulate calcium carbonate as the main abrasive cleaning agent. By using a mixture of relatively fine particulate calcium carbonate with a certain level of relatively coarse particulate calcium carbonate, the toothpaste provides for a reduced RDA while maintaining the same cleaning efficacy in comparison with the use of only the relatively fine particulate calcium carbonate

US6022528A: The present invention relates to an effervescent oral care composition with improved interproximal delivery properties. The composition comprises a first composition with about 2.5 percent by weight of an alkalimetal bicarbonate and a second composition with an acidic compound. Upon bringing the two compositions into contact with each other, e.g. by extruding them from a multicompartment container through a single outlet orifice, the alkalimetal bicarbonate and the acidic compound react with each other, causing an effervescent effect. By using 0.02 percent to less than 0.5 percent by weight, calculated on the total weight of the oral care composition, of the acidic compound, the interproximal delivery properties of the composition are significantly improved

GB2299263A: A dental applicator such as a toothbrush, for use with a dental product, eg. having stain removal properties, bears on the handle (10) adjacent the head (12) an indicator patch (14) carrying a colour indicator which changes colour responsively to repeated contacts with the dental product, eg. being bleached by repeated contacts with a bleaching agent incorporated in the dental product.

WO9605802A2:   The present invention relates to oral care compositions with an improved teeth whitening effect. This effect is achieved by inclusion in the oral care compositions of certain organic peroxy acids as teeth whitening/bleaching agents, particularly peroxyamidophthalamides and cationic peroxycarboxylic acids such as N-phthalimido per hexanoic acid and quaternary benzylperoxyacid.  

EP0658565A1  The present invention relates to copper, stannous and zinc salts of polyhydroxy compounds having at least one acid, ester-linked salt-forming substituent. These salts have anti-bacterial activity and are useful for inclusion in personal care compositions, particularly in oral care compositions, to impart anti-plaque, anti-caries, anti-gingivitis properties thereto. Several of these salts are novel compounds; typical examples are stannous and copper salts of glucose-6-phosphate

WO9502392A1:  The present invention relates to an effervescent oral care composition with improved sensory properties. The composition comprises a first composition with alkalimetal bicarbonate and a second composition with an acidic compound. Upon bringing the two compositions into contact with each other, e.g. by extruding them from a multicompartment container through a single outlet orifice, the alkalimetal bicarbonate and the acidic compound react with each other, causing an effervescent effect. By using 2.5-10 percent by weight of the alkalimetal bicarbonate, the sensory properties of the composition are significantly improved, while maintaining the same degree of effervescence as compared to similar systems with 15 percent or more alkalimetal bicarbonate

GB2273673A:  A dental active material such as a fluoride is delivered to the oral cavity by electrostatic spraying. The dental active material can be sprayed at ultra-low flow rates

US5258173A: The present invention relates to a dentifrice composition comprising a stannous compound that releases stannous ions in the composition such as stannous fluoride or stannous pyrophosphate. These stannous ions can be converted in the composition into the inactive stannic ions, and to prevent such conversion according to the present invention an antioxidant is incorporated into the composition, such as butylated hydroxyanisole, butylated hydroxytoluene and ethyl vanillin.
