Definitions
- the present invention relates to oral hygiene compositions, in particular remineralising compositions comprising a source of calcium ions and a source of phosphate ions.
- Such compositions are of use in the prophylaxis and treatment of caries and/or sensitivity.
- the present invention provides a remineralising composition
- a remineralising composition comprising: a) as a first component an aqueous calcium phase comprising a water- soluble calcium salt providing from 0.05 to 10%, by weight of the calcium phase, of calcium ions, and b) as a second component an aqueous phosphate phase comprising a stabilising amount of a polyphosphate salt and a water-soluble phosphate salt providing from 0.05 to 10%, by weight of the phosphate phase, of phosphate ions; the two phases being kept separate until use, whereupon on mixing they provide a single phase having a pH from 2.0 to 5.0 and a molar ratio of calcium ions to phosphate ions of from 0.5:1 to 5:1 capable of remineralising teeth.
- compositions of the present invention have the advantage of forcing deep remineralisation and thus are expected to be of use in the prophylaxis and treatment of caries and/or sensitivity.
- calcium and phosphate ions remain soluble, by virtue of the initial pH of the applied compositions, and can diffuse deeply within carious lesions and/or dentinal tubules. As the pH rises within a tooth, for example by the subsequent action of saliva, precipitation of calcium phosphate occurs resulting in deep remineralisation.
- the calcium salt provides from 1 to 5%, preferably from 2 to 3% , by weight of the calcium phase, of calcium ions.
- Suitable examples of calcium salts include calcium acetate, calcium formate, calcium lactate, calcium nitrate and mixtures thereof, and preferably, is calcium chloride or a mixture of calcium chloride and calcium lactate.
- the phosphate salt provides from 1 to 5%, preferably from 2 to 3% , by weight of the phosphate phase, of phosphate ions.
- Suitable examples of phosphate salts include disodium hydrogen phosphate, potassium dihydrogen phosphate, trisodium phosphate and, preferably, sodium dihydrogen phosphate. It is important that the phosphate phase comprises a stabilising amount of a polyphosphate salt which improves the long term storage stability and efficacy of the remineralising composition.
- the polyphosphate salt is an alkali metal pyrophosphate or tripolyphosphate.
- it is an alkali metal polymetaphosphate for example sodium polymetaphosphate (otherwise known as Graham's salt or sodium hexametaphosphate) .
- the polyphosphate salt is present up to 250 ppm, preferably from 5 to 200 ppm, most preferably from 5 to 20 ppm, by weight of the phosphate phase.
- the pH of the calcium and phosphate phases are such that on mixing they result in a pH from 2.0 to 5.0, preferably 3.0 to 4.5, more preferably 3.5 to 4.0, most preferably 3.5 to 3.8. Conveniently equal amounts, by weight, of the calcium and phosphate phases are mixed prior to use.
- the pH of the calcium phase is from 3.0 to 7.0, preferably 3.0 to 6.0.
- the pH of the phosphate phase is from 3.0 to 6.5, preferably 3.5 to 6.0.
- the molar ratio of calcium ions to phosphate ions should be such to ensure effective remineralisation of teeth.
- the molar ratio of calcium ions to phosphate ions is from 1 :1 to 3:1 , eg 2:1.
- composition of the present invention comprises in the phosphate phase a source of fluoride ions, such as an alkali metal fluoride (eg sodium fluoride), an amine fluoride or an alkali metal monofluorophosphate (eg sodium monofluorophosphate).
- a source of fluoride ions such as an alkali metal fluoride (eg sodium fluoride), an amine fluoride or an alkali metal monofluorophosphate (eg sodium monofluorophosphate).
- the composition comprises from 50 to 2500 ppm of fluoride ions, eg from 100 to 1500 ppm of fluoride ions by weight of the total composition.
- the composition comprises a catalytic amount of fluoride ions, preferably from sodium fluoride, eg up to 50 ppm, suitably up to 20 ppm, preferably between 1 and 10 ppm, most preferably between 4 and 6 ppm of fluoride ions, by weight of the total composition.
- a catalytic amount of fluoride ions preferably from sodium fluoride, eg up to 50 ppm, suitably up to 20 ppm, preferably between 1 and 10 ppm, most preferably between 4 and 6 ppm of fluoride ions, by weight of the total composition.
- Suitable compositions of the present invention include rinses, gels or dentifrices, providing that the calcium and phosphate phases are kept separate until use.
- compositions can be packaged into a container such as bottle or tube having two chambers for separating each phase, the container having a dispensing nozzle allowing controlled dispensing and preferably concomitant mixing of said phases prior to use.
- a container such as bottle or tube having two chambers for separating each phase
- the container having a dispensing nozzle allowing controlled dispensing and preferably concomitant mixing of said phases prior to use.
- compositions can be packaged into a sachet having two chambers separated by a frangible seal which can be ruptured prior to use allowing mixing of the calcium and phosphate phases within the sachet.
- the calcium and phosphate phases may also be packaged in separate containers which can dispense the required amount of each phase prior to mixing and use.
