Definitions

  • the present invention relates to chewing gum compositions containing polymeric surface active agents, including polyphosphates. These polymeric surface active agents may provide novel surface conditioning reaction to oral surfaces such as the teeth and mucosa. This leads to improved cleaning impression.
  • the present invention further relates to compositions wherein the chewing gum has a crunchy texture conferred to it by the polyphosphate particles.
  • Polymeric surface active agents such as polyphosphates
  • Polyphosphates are known in the oral care art. Although disclosed in chewing gum compositions, these ingredients are most commonly found in dentifrice compositions. Polyphosphates are known to provide an anti-calculus benefit as stated in U.S. Patent 5,094,844, US 4808401 and EP 0333301 issued to Gaffar et al.. Polyphosphates are also know to provide a buffering effect within zinc comprising oral compositions as stated in U.S. Patent 4,170,632 and US 4,170,633 both to Wagenknecht, deceased et al. Other chewing gum patents disclosing a polyphosphate include U.S. patent 5,702,687 issued to Miskewitzand EP0,387,024 issued to McClanahan.
  • confectionery gums wherein sugars and sugar substitutes (such as isomalt, candy and the like), sometimes in conjunction with freeze dried food stuffs, are distributed throughout the body of the gum for the purpose, at least in part, of providing a "crunchy" texture are also known (FR 2,748,902; GB 950,811 ; EP 017,691 ; US 5,958472, and US 5,017,385). Whilst these latter disclosures do provide useful advances in conferring a "crunchy" sensation to the gum they do so by the use of food stuffs and not by use of the oral care active itself.
  • the surface conditioning effects can measured using several different methods.
  • the surface conditioning effects on a subject's teeth and oral mucosa can be measured in vivo. These measurements include consumer responses on questions concerning clean teeth and smooth teeth. Other in vivo measurement include the water contact angle on the tooth surface and on the mucosa surfaces.
  • the surface conditioning effects can also be measured in considerable detail through in vitro methods. In vitro methods are made over time to measure surface free energies and pellicle film thickness and composition.
  • the polymeric surface active agent can help to reduce the astringency of a metallic ion. Additionally, this reduction in astringency can occur without significantly reducing the efficacy of the metallic ion and without significantly reducing the efficacy and the surface conditioning effects of the polymeric surface active agent.
  • a first aspect of this invention relates to a chewing gum composition
  • a chewing gum composition comprising a polymeric surface active agent.
  • the chewing gum composition may also contain a cationic material and/or an orally active metallic ion.
  • the chewing gum composition will provide surface conditioning effects on a subject's teeth and/or oral mucosa.
  • the surface conditioning effects can by measured through in vitro or in vivo testing.
  • the in vitro testing shows a total surface energy and/or a lewis base score to increase immediately after treatment with the chewing gum and then decrease overtime.
  • the in vivo testing shows a water contact angle of the oral mucosa to decrease after treatment with the chewing gum composition and/or a significantly higher smooth teeth feel relative to other chewing gum compositions.
  • the present invention also relates to methods of providing surface conditioning effects to a subject comprising administering to the subject a chewing gum comprising a polymeric surface active agent.
  • the present invention also relates to methods of reducing astringency of a chewing gum containing a metallic ion without significantly reducing the efficacy of the metallic ion.
  • this invention relates to a chewing gum composition which has a crunchy texture wherein the crunchy texture is conferred to the gum by the inclusion of particulate polyphosphate material within the composition.
  • the "crunchy" texture can be attained when the polyphosphate material used has a particle size of between 100 ⁇ m and 2000 ⁇ m. Furthermore, by ensuring that the polyphosphate is at least sparingly soluble the "crunch” will slowly disappear to leave a non gritty gum.
  • the chewing gum compositions of the present invention may be in the form of a conventional chewing gum or any other product form which is suitable for chewing. Suitable physical forms include sticks, dragees, chiclets, and batons.
  • the chewing gum may also be a digestible or dissolvable gum suitable for chewing.
  • a chewing gum is typically retained in the oral cavity for a time sufficient to allow ingredients released to contact substantially all of the dental surfaces and/or oral tissues for purposes of oral activity.

Abstract

La présente invention concerne une composition de chewing-gum contenant un agent tensioactif polymère. Un second aspect de cette invention concerne un chewing-gum croquant dans lequel la texture croquante est obtenue par des particules de polyphosphate particulaire à l'intérieur de la formulation et laquelle dure pendant toutes les minutes initiales de mastication. La composition de chewing-gum peut également contenir une matière cationique et/ou un ion métallique actif oralement. La composition de chewing-gum procure des effets de conditionnement de surface sur les dents d'un sujet et/ou la muqueuse orale et la texture 'croquante' est utilisée comme sensation pour renforcer ces effets. Les effets de conditionnement de surface peuvent être mesurés par essais in vitro ou in vivo. L'essai in vitro montre une énergie de surface totale et/ou un indice de base lewis augmentant immédiatement après traitement avec le chewing-gum et diminuant ensuite dans le temps. L'essai in vivo montre un angle de contact de l'eau de la muqueuse orale diminuant après traitement avec la composition de chewing-gum et/ou une sensation de douceur aux dents sensiblement supérieure par rapport à d'autres compositions de chewing-gum. La présente invention concerne également des procédés procurant des effets de conditionnement de surface à un sujet consistant à administrer au sujet un chewing-gum contenant un agent tensioactif polymère. L'invention concerne également des procédés de réduction de l'astringence d'un chewing-gum contenant un ion métallique actif oralement, sans réduire de manière significative l'efficacité de l'ion métallique.
