Definitions

  • compositions comprising one or more phosphate derivatives, and carrier materials wherein the compositions are in a form suitable for oral or topical administration.
  • These compositions preferably contain a safe and effective amount of one or more active materials such as those which provide nutritional, therapeutic, antimicrobial, pharmaceutical medicinal, and/or aesthetic benefit, and those commonly used in health care products.
  • a wide variety of flavor, coolant and sweetener agents are used in consumer and health care products today.
  • Aesthetic qualities of these compositions such as taste, smell, mouthfeel, and after-taste are important concerns for consumer acceptability. Products with poor flavor, a bad after-taste or other negative aesthetics may limit consumer acceptability initially or over an extended period of time, thereby limiting consumer usage and compliance with treatment regimens.
  • An additional aspect of consumer acceptability and compliance is the consumer's perception of efficacy. Consumer satisfaction with a product is likely to be increased if some type of sensory signal exists to remind the consumer that the product is working after ingestion, administration or expectoration.
  • phosphate derivatives comprising flavor, coolant, and/or sweetener components may be incorporated into oral or topical compositions to deliver pleasing aesthetics and high consumer acceptability. It has also been discovered that these compositions for oral or topical administration may be formulated to include a safe and effective amount of one or more actives. These compositions may provide sustained coolant, flavor and/or sweetener activity, depending on the particular derivative being used. These phosphate derivatives may also serve to improve the aesthetics of the compositions and provide a sensory signal to the user.

  • the present invention also includes the instance where one R group acts both as an antimicrobial and a flavorant or coolant.
  • Mixed pyrophosphate diesters are also included herein, ie, where the compound contains one R group which is a coolant and one R group which is a flavor.
  • the mixed pyrophosphate compound provides three benefits: tartar control, flavor and cooling.
  • one R group can be a flavor or coolant and the other R group can be a safe, hydroxyl-containing antimicrobial group. If an antimicrobial group is included, three benefits can be achieved by inclusion of only this one type of active in the oral composition: good taste (coolant/flavor), tartar . control and antimicrobial effect.
  • this compound is believed to lead to a reduction in plaque formation on the teeth and/or a decrease in the incidence and/or severity of gingivitis and/or prevention or reduction of mouth odor. Further without meaning to be bound by theory, it is believed that the tartar control effect is achieved by the parent compound or by inorganic pyrophosphate which is released when the parent compound is cleaved by phosphatase enzyme present in the oral cavity.
  • both a flavor effect and a low level antimicrobial effect are conveyed in addition to tartar control. If the other R group is then a coolant, a fourth benefit (cooling taste) is believed to be conveyed.
  • Compounds of this type may provide antitartar activity without attendant unpleasant taste.
  • Oral compositions containing pyrophosphates can convey a bitter taste.
  • a pyrophosphate such as this one which can control tartar and at the same time taste good (or have improved taste) is surprising and beneficial.
  • Another advantage of this compound is that a single compound can provide multiple benefits: tartar control, improved taste (cooling and/or flavoring and/or sweetening) and/or an antimicrobial effect. It is also believed that one or more of these four effects, cooling, flavor, antimicrobial, and tartar control, may surprisingly be sustained effects.
  • sustained means that one or more of these effects continues for some time after administration or use of the oral composition containing the present pyrophosphate diesters. Thus, compound remaining in the oral cavity, for example, adhered either on the plaque itself or on the teeth, would continue to be cleaved by phosphatase enzyme, which is commonly present in saliva and in plaque.
  • phosphatase enzyme acid or alkaline phosphatases and pyrophosphatases.
  • Preferred is from about 0.01% to about 15%, more preferably from about 0.05% to about 10%, most preferably from about 0.5 to about 5%, by weight of the composition, of the pyrophosphate compound. Also preferred is from about 85% to about 99.99%, more preferably from about 90% to about 99.05%, most preferably from about 95% to about 99.5%, by weight of the composition, of carrier material.
  • the oral composition herein is preferably toothpaste (most preferred), mouthrinse, or liquid dentifrice.
  • Sodium fluoride is preferably included in dentifrice compositions herein.
  • Components to be added should be safe for oral use. By “safe” is meant without undue adverse side effects (such as toxicity, irritation or allergic response) commensurate with a reasonable benefit/risk ratio when used in the manner of this invention.
  • Preferred pyrophosphate diesters are selected from the group consisting of 1 ,2-bis-menthyl-dihydrogen pyrophosphate, 1 ,2-bis-thymyl-dihydrogen pyrophosphate, 1,2-bis-vanillyl-dihydrogen pyrophosphate, 1,2-bis-eugenyl- dihydrogen pyrophosphate, 1,2-bis-methyl salicylyl-dihydrogen pyrophosphate; and mixtures thereof.

  • BMPP which has a menthol component
  • BMPP when taken into the oral cavity in, for example, a mouthrinse, has a sweet initial flavor and a surprisingly long lasting (eg, up to one hour and perhaps beyond) cooling effect.
  • This flavor was quite surprising since pyrophosphates and menthol are known to have an unpleasant taste.
  • BMPP is also believed to reduce and/or prevent tartar formation.
  • BMPP can be synthesized by coupling the phosphate, menthyl monophosphate ("MMP"), via a dehydration reaction using dicyclohexylcarbodiirr., je (“DCC”).
