Description
ORAL CARE COMPOSITION
Field of the Invention
The present invention relates to oral care compositions in particular oral care that are free from preservatives.
Background of the Invention
A key attribute for oral care products is that they are free from microbial and fungal contamination. Thus, there is a need for oral care products that provide consistent and reproducible resistance to bacterial growth and mould, while maintaining their efficacy and consumer acceptability. Oral care products having a high water content and a silica abrasive can be difficult to preserve, especially in the absence of preservatives.
WO 2013/095370 provides oral care compositions comprising: greater than 50 weight % water; an effective amount of benzyl alcohol; and a silica abrasive that are said to provide adequate preservation.
WO 2018/145988 discloses compositions oral care comprising low levels of sodium fluoride.
WO 2014/100930 discloses the use of a water-soluble source of stannous ions for improving the robustness towards microbial challenge of oral care compositions.
Toothpastes that contain higher levels of water are desirable from both a cost and sustainability point of view. There is now a consumer preference for products that minimise the use of preservatives and lower the level of fluoride, thus products that are self-preserving are desirable.
Description of the Invention
The present invention relates to a toothpaste composition comprising: i) 40 wt% or greater of the total composition of water, ii) silica abrasive, iii) from 0.05 wt% to 0.15 wt%, of the total composition of sodium fluoride, iv) 0.4 wt% of the total composition of zinc sulphate.
The invention further relates to the use of zinc sulphate to mitigate fungal contamination in a toothpaste composition comprising 40wt% or greater of water of the total composition of water and from 0.05 wt% to 0.15 wt% the total composition of fluoride.

These proportions of thickeners in the dentifrice compositions of the present invention form an extrudable, shape-retaining product which can be squeezed from a tube onto a toothbrush and will not fall between the bristles of the brush but rather, will substantially maintain its shape thereon. Suitable thickeners or gelling agents useful in the practice of the present invention include inorganic thickening silicas such as amorphous silicas available from Huber Corporation under the trade designation Zeodent 165, Irish moss, iota-carrageenan, gum tragacanth, and polyvinylpyrrolidone.
Compositions according to the invention preferably comprise a polymeric deposition aid. Preferably the composition comprises acid anhydride polymers, particularly preferred are copolymers of maleic anhydride with methyl vinylether, in which the anhydride moiety may be in a partially or fully hydrolysed or alcoholysed form. Preferred copolymers include Gantrez(R) polymers such as:
Gantrez S-95: molecular weight 216,000; free acid;
Gantrez S-96: molecular weight 700,000; free acid;
Gantrez S-97: molecular weight 1 ,500,000; free acid; and
Gantrez MS-955: molecular weight 1,060,000; calcium/sodium salt.
Particularly preferred co-polymers of maleic acid and methyl vinylether have a molecular weight of 1,000,000 or greater and an especially preferred material is Gantrez S-97.
Compositions according to the invention may comprise a tooth whitening agent. The whitening agent preferably comprises a green and/or a blue pigment. In the context of the present invention a pigment is generally understood to be a shade/material which is insoluble in the relevant medium, at the relevant temperature. This is in contrast to dyes which are soluble. In the context of this invention, the "relevant medium" is human saliva, the liquid medium in which the composition is used, at the temperature of the oral cavity during brushing of the teeth, i.e. up to 37 Degrees C. As a reasonable approximation, the relevant medium may be considered to be water and the relevant temperature to be 25 Degrees C.
Preferably the blue pigment is Pigment Blue 15, more preferably Pigment Blue 15:1 , 15:2, 15:3, 15:4, 15:5 or 15:6, most preferably 15:1. A preferred pigment is blue pigment is Phthalocyanine Blue Pigment, Cl No. 74160, blue covarine.
The preferred Green pigment is Phthalocyanine Green, preferably Phthalocyanine Green CI- 74260.
Preferably the total level of pigment in the composition is from 0.01 wt% to 3 wt, more preferably from 0.02 to 2 wt%.
If the composition is a toothpaste it may be a dual phase paste, with the whitening pigments present in one phase.
Compositions according to the invention may comprise oral care enzyme systems such as hydrogen peroxide producing enzyme systems (e.g. the oxidoreductase enzyme glucose oxidase), amyloglucosidase, dextranase and/or mutanase, (optionally in the presence of zinc ion providing compounds and/or 8- hydroxyquinoline derivatives), lactoperoxidase, lactoferrin, lysozyme and mixtures thereof.
In one embodiment a preferred class of oral care active for inclusion in the compositions of the invention includes agents for the remineralisation of teeth. The term “remineralisation” in the context of the present invention means the in situ generation of hydroxyapatite on teeth.
A specific example of a suitable agent for the remineralisation of teeth is a mixture of a calcium source and a phosphate source which, when delivered to the teeth results in the in situ generation of hydroxyapatite on teeth.
Illustrative examples of the types of calcium source that may be used in this context (hereinafter termed “remineralising calcium sources”) include, for example, calcium phosphate, calcium gluconate, calcium oxide, calcium lactate, calcium glycerophosphate, calcium carbonate, calcium hydroxide, calcium sulphate, calcium carboxymethyl cellulose, calcium alginate, calcium salts of citric acid, calcium silicate and mixtures thereof. Preferably the remineralising calcium source is calcium silicate.
The amount of remineralising calcium source(s) (e.g. calcium silicate) in the composition of the invention typically ranges from 1 to 30%, preferably from 5 to 20% by total weight remineralising calcium source based on the total weight of the oral care composition.
Illustrative examples of the types of phosphate source that may be used in this context (hereinafter termed “remineralising phosphate sources”) include, for example, monosodium
dihydrogen phosphate, disodium hydrogen phosphate, sodium pyrophosphate, tetrasodium pyrophosphate, sodium tripolyphosphate, sodium hexametaphosphate, potassium dihydrogenphosphate, trisodium phosphate, tripotassium phosphate and mixtures thereof. Preferably the remineralising phosphate source is a mixture of trisodium phosphate and sodium dihydrogen phosphate.
The amount of remineralising phosphate source(s) (e.g. trisodium phosphate and sodium dihydrogen phosphate) in the composition of this invention typically ranges from 2 to 15%, preferably from 4 to 10% by total weight remineralising phosphate source based on the total weight of the oral care composition.
Mixtures of any of the above described materials may also be used.
