Tannpleiepreparat. Dental care preparation.

formig "bærermateriale og et poleringsmiddel som gir en meget onsket virkning. shaped "carrier material and a polishing agent which gives a very desirable effect.
Tannpleiepreparater som anvendes for å rense tennene, inne- Dental care preparations used to clean the teeth, containing

De anvendte poleringsmidler omfatter kalsiumcarbonat, dikalsiumfosfater, trikalsiumfosfat, kalsiumpyro- usually holds a significant amount of a polishing agent that works to remove stains on the teeth. The polishing agents used include calcium carbonate, dicalcium phosphates, tricalcium phosphate, calcium pyro-
fosfat og tilsvarende magnesiumsalter. phosphate and corresponding magnesium salts.
Det er også blitt foreslått å anvende forskjellige typer av siliciumholdige materialer, som silika-gel eller amorft silicium- It has also been proposed to use different types of silicon-containing materials, such as silica gel or amorphous silicon
dioksyd, som poleringsmidler for tannpleiepreparater. Dette har ikke vært gunstig da enkelte materialer inneholdende silicium ikke har dioxide, as polishing agents for dental care preparations. This has not been beneficial as some materials containing silicon do not
vært tilstrekkelig slipende til å gi en onsket poleringsgrad. På den annen side har enkelte materialer inneholdende silicium, som sand eller kvarts, hatt en slik storrelse og slipekraft at de kunne bevirke en uonsket slitasje på tannemaljen, og for å unngå dette var det nodvendig å belegge slike materialer med et harpiksmateriale for å minske etsev.irkningen. Denne fremgangsmåte er imidlertid komplisert og hindrer poleringsmidlet fra å kunne anvendes som et bærermateriale for alle bestanddeler i tannpleiepreparatet og i kontakt med alle bestanddeler i tannpleiepreparatet. been sufficiently abrasive to provide a desired degree of polishing. On the other hand, certain materials containing silicon, such as sand or quartz, have had such a size and abrasive force that they could cause an unwanted wear on the tooth enamel, and to avoid this it was necessary to coat such materials with a resin material to reduce etching .the anger. However, this method is complicated and prevents the polishing agent from being able to be used as a carrier material for all components of the dental care preparation and in contact with all components of the dental care preparation.
Det er en fordel ved oppfinnelsen at det afrVéftdes et siliciumdioxyd-materiale med en slik poleringsvirkning at det effektivt kan anvendes som bærermateriale for' tannpleiepreparatet homogent fordelt i dette og i kontakt med de ovrige bestanddeler i tannpleiepreparatet. It is an advantage of the invention that it produces a silicon dioxide material with such a polishing effect that it can be effectively used as a carrier material for the dental care preparation homogeneously distributed in it and in contact with the other components of the dental care preparation.
Det er dessuten en fordel ved oppfinnelsen at det tilveie-bringes et tannpleiepreparat hvori det med god virkning kan anvendes kationiske materialer. It is also an advantage of the invention that a dental care preparation is provided in which cationic materials can be used with good effect.
Oppfinnelsen angår et tannpleiepreparat inneholdende minst The invention relates to a dental care preparation containing at least
30 vekt% polerings- og bærermateriale hvorav i det minste en hovedsakelig mengde utgjores av et vannuopploselig, krystallinsk siliciumdioxyd jevnt fordelt og i kontakt med tannpleiepreparatets bestanddeler, og tannpleiepreparatet er særpreget ved at det krystallinske siliciumdioxyd består av a) partikler med en storrelse inntil 5 Mm og en gjennomsnittlig partikkelstorrelse inntil 1,1 ^m og med et overflateareal inntil 50.000 cm /g eller b) partikler hvorav minst 75% har en mindre storrelse enn 5 Mm og som har en gjennomsnittlig partikkelstorrelse av 1,1 - 2,06 ju.m og et overf lateareal av 11.000-50.000 cm og er tilstede i en mengde inntil 3<>>+,3 vekt%. 30% by weight of polishing and carrier material, of which at least a substantial amount consists of a water-insoluble, crystalline silicon dioxide evenly distributed and in contact with the components of the dental care preparation, and the dental care preparation is characterized by the fact that the crystalline silicon dioxide consists of a) particles with a size of up to 5 mm and an average particle size of up to 1.1 µm and with a surface area of up to 50,000 cm /g or b) particles of which at least 75% have a size smaller than 5 Mm and which have an average particle size of 1.1 - 2.06 ju. m and a surface area of 11,000-50,000 cm and is present in an amount of up to 3<>>+.3% by weight.
Bærermaterialet som anvendes ifolge oppfinnelsen, utgjores i det minste hovedsakelig av et vannuopploselig, krystallinsk siliciumdioxyd med en partikkelstorrelse av inntil (dvs. ikke over) 5 Mm. The carrier material used according to the invention is made up at least mainly of a water-insoluble, crystalline silicon dioxide with a particle size of up to (ie not over) 5 mm.
Når det anvendes i storre mengder, kan siliciumdioxydets partikler betraktes som om de gjennomsnittlig er i det vesentlige kuleformige. Da kuleformige partiklers overflateareal oker omvendt proporsjonalt med kvadratet av den gjennomsnittlige partikkelstorrelse, er således overflatearealet 20.600 cm 2/g når den gjennomsnittlige partikkelstorrelse er 1,1 jim0 En del gjennomsnittlige partikkelstorrelser og overflatearealer for krystallinsk siliciumdioxyd er angitt nedenfor: When used in large quantities, the silicon dioxide particles can be considered to be, on average, substantially spherical. As the surface area of spherical particles increases inversely proportional to the square of the average particle size, the surface area is thus 20,600 cm 2 /g when the average particle size is 1.1 jim0 Some average particle sizes and surface areas for crystalline silicon dioxide are given below:
De tre sistnevnte kvaliteter tilfredsstiller således fordringene til gjennomsnittlig partikkelstorrelse og overflateareal for det krystallinske siliciumdioxyd i tahnpleiepreparatene ifolge oppfinnelsen. The three latter qualities thus satisfy the requirements for average particle size and surface area for the crystalline silicon dioxide in the toothpaste preparations according to the invention.
Den virkelige storrelse for hver partikkel av krystallinsk siliciumdioxyd i bærermaterialet som anvendes ifolge oppfinnelsen, The actual size of each particle of crystalline silicon dioxide in the carrier material used according to the invention,
varierer selvfolgelig, men partiklene har for minst 75%'s vedkom-mende en storrelse under 5 Mm. Partikkelstorrelsesområdene for en del i handelen tilgjengelige kvaliteter av krystallinsk siliciumdioxyd er angitt nedenfor: varies, of course, but the particles have a size below 5 mm for at least 75% of them. The particle size ranges for some commercially available grades of crystalline silicon dioxide are given below:
Av disse siliciumdioxydkvaliteter tilfredsstiller således Of these silicon dioxide qualities thus satisfy
de tre forstnevnte fordringene til gjennomsnittlig partikkelstorrelse og hoyeste partikkelstorrelse for det krystallinske siliciumdioxyd i tannpleiepreparatene ifolge oppfinnelsen. Slike siliciumdioxydkvaliteter er tilgjengelige i handelen. the three first-mentioned requirements for average particle size and highest particle size for the crystalline silicon dioxide in the dental care preparations according to the invention. Such silicon dioxide grades are commercially available.
Det ifolge oppfinnelsen anvendte krystallinske siliciumdioxyd er ikke-porost og har en noytral pH av 7,0 når det er dis-pergert i vann. Det anvendes som regel i nærvær av mindre mengder og spormengder av forurensninger (dvs. under 1% samlet), som treverdig jernoxyd, aluminiumoxyd, titandioxyd, kalsiumoxyd og magne siumoxyd. The crystalline silicon dioxide used according to the invention is non-porous and has a neutral pH of 7.0 when dispersed in water. It is usually used in the presence of smaller amounts and trace amounts of contaminants (ie less than 1% in total), such as trivalent iron oxide, aluminum oxide, titanium dioxide, calcium oxide and magnesium oxide.
Poleringsmidlet inneholdende krystallinsk siliciumdioxyd anvendes som bærermateriale for et tannpleiepreparat i en mengde av minst 30 vekt%, f.eks. 30-99 vekt$, og som regel 30-75 vékt%, i en tannkrem eller tanntablett og i en mengde av 70-99 vekt% i et tann-pulver. Det ifolge oppfinnelsen anvendte krystallinske siliciumdioxyd kan være det eneste poleringsmiddel eller det kan anvendes sammen med andre poleringsmidler. Når det anvendes alene, skal den anvendte mengde være minst 30 vekt% av tannpleiepreparatet, og det skal være tilstede i en hovedsakelig mengde (dvs. minst halvparten) når det anvendes i blanding med et annet poleringsmiddel. The polishing agent containing crystalline silicon dioxide is used as carrier material for a dental care preparation in an amount of at least 30% by weight, e.g. 30-99% by weight, and as a rule 30-75% by weight, in a toothpaste or dental tablet and in an amount of 70-99% by weight in a tooth powder. The crystalline silicon dioxide used according to the invention can be the only polishing agent or it can be used together with other polishing agents. When used alone, the amount used should be at least 30% by weight of the dental care preparation, and it should be present in a major amount (ie at least half) when used in admixture with another polishing agent.
Poleringsmidler som ifolge oppfinnelsen kan anvendes sammen med det krystallinske siliciumdioxyd, omfatter dikalsiumfosfat, trikalsiumfosfat, uopplbselig natriummetafosfat, aluminiumhydroxyd, magnesiumcarbonat, kalsiumcarbonat, kalsiumpyrofosfat, kalsium-sulfat, polymethylmethacrylat eller bentonittetc. eller egnede blandinger derav. Dersom disse poleringsmidler anvendes, er de til-stede i en mindre mengde(dvs.inntil halvparten) i poleringsmidlet. Om onskes kan en mindre mengde krystallinsk siliciumdioxyd med et vesentlig antall partikler med en storrelse over 5f-un anvendes sammen med det krystallinske materiale som har partikler med en storrelse av som regel under 5Pia,for å regulere poleringsgraden efter bnske. Polishing agents which according to the invention can be used together with the crystalline silicon dioxide include dicalcium phosphate, tricalcium phosphate, insoluble sodium metaphosphate, aluminum hydroxide, magnesium carbonate, calcium carbonate, calcium pyrophosphate, calcium sulphate, polymethyl methacrylate or bentonite etc. or suitable mixtures thereof. If these polishing agents are used, they are present in a smaller amount (ie up to half) in the polishing agent. If desired, a smaller amount of crystalline silicon dioxide with a significant number of particles with a size above 5µm can be used together with the crystalline material which has particles with a size of usually below 5µm, in order to regulate the degree of polishing as desired.
Ved fremstillingen av tannpulvere er det som regel tilstrekkelig mekanisk, f.eks.ved maling,! blande de forskjellige faste bestanddeler i egnede mengder og med egnede partikkelstorrelser. In the production of tooth powders, it is usually sufficient mechanically, e.g. when painting,! mixing the various solid components in suitable quantities and with suitable particle sizes.
I tannkremer bor mengdene av væskene og de faste stoff.er nødvendigvis avpasses slik at det dannes en kremaktig masse med bnsket konsistens som kan ekstruderes fra en aerosolbeholder eller en sammenklembar tube,f.eks. av aluminium eller bly.Væskene i tannkremen er som regel hovedsaklig vann, glycerol, vandige opp-losninger av sorbitol, propylenglycose eller polyethylenglycose ^00 etc. eller egnede blandinger derav. Det er som regel fordel-aktig å anvende en blanding av både vann og et fuktemiddel eller In toothpastes, the amounts of the liquids and the solids must be adjusted so that a creamy mass with a sticky consistency is formed which can be extruded from an aerosol container or a squeezable tube, e.g. of aluminum or lead. The liquids in the toothpaste are generally mainly water, glycerol, aqueous solutions of sorbitol, propyleneglycose or polyethyleneglycose ^00 etc. or suitable mixtures thereof. It is usually advantageous to use a mixture of both water and a wetting agent or
bindemiddel, som glycerol eller sorbitol. Det samlede væskeinn-hold er som regel 20-75 vekt % av preparatet. Det foretrekkes binder, such as glycerol or sorbitol. The overall liquid content is usually 20-75% by weight of the preparation. It is preferred
dessuten å anvende et geleringsmiddel i tannkremer,som de natur-lige og syntetiske gummier og gummiliknende materialer, f.eks. furthermore, to use a gelling agent in toothpastes, such as the natural and synthetic gums and gum-like materials, e.g.
irsk mose,tragant-gummi, methylcellulose, hydroxyethyl-cellulose, irish moss, gum tragacanth, methylcellulose, hydroxyethyl cellulose,
natriumcarboxymethylcellulose, polyvinylpyrrolidon eller stivelse, som regel i en mengde av inntil ca. 10$, fortrinnsvis 0, 5- 5%, av preparatet. De foretrukne geleringsmidler er methylcellulose og hydroxyethylcellulose. sodium carboxymethylcellulose, polyvinylpyrrolidone or starch, usually in an amount of up to approx. 10$, preferably 0.5-5%, of the preparation. The preferred gelling agents are methylcellulose and hydroxyethylcellulose.
Det anvendes i preparatene ifolge oppfinnelsen organiske overflateaktive midler for å oppnå en oket profylaktisk virkning, for å lette oppnåelsen av en god og fullstendig dispergering av de foreliggende preparater i munnhulen og for å gjore de foreliggende preparater kosmetisk mer aksepterbare. Det organiske overflateaktive materiale kan være anionaktivt, ikke-ionisk, amfolytisk eller kationaktivt, og det foretrekkes som overflateaktivt middel å anvende et rensende materiale som gjor preparatet rensende og skummende. Organic surfactants are used in the preparations according to the invention to achieve an increased prophylactic effect, to facilitate the achievement of a good and complete dispersion of the present preparations in the oral cavity and to make the present preparations cosmetically more acceptable. The organic surface-active material can be anion-active, non-ionic, ampholytic or cation-active, and it is preferred as surface-active agent to use a cleansing material which makes the preparation cleansing and foaming.
Som kationiske overflateaktive midler kan spesielt anvendes slike som omfatter kimdrepende midler og antibakterielle forbindelser , som di-isobutylfenoxyethyldimethylbenzylammoniumklorid, benzyldimethylstearylammoniumklorid, tertiære aminer med en fettalkylgruppe med 12-18 carbonatomer og 2(poly)-oxyethylengrupper bundet til nitrogénatomet (som regel inneholdende et samlet antall av 2-50 etha-noxygrupper pr„ molekyl) og salter derav med syrer, og forbindelser med formelen As cationic surfactants, those that include germicides and antibacterial compounds, such as diisobutylphenoxyethyldimethylbenzylammonium chloride, benzyldimethylstearylammonium chloride, tertiary amines with a fatty alkyl group with 12-18 carbon atoms and 2(poly)oxyethylene groups bound to the nitrogen atom (usually containing a total number of of 2-50 ethoxy groups per molecule) and salts thereof with acids, and compounds with the formula
hvor R er en fettalkylgruppe inneholdende ca. 12-18 carbonatomer og x, y og z samlet 3 eller hoyere, og salter derav med mineral-syrer eller organiske syrer kan også anvendes. Det foretrekkes å anvende 0,05-5 vekt% av de ovenfor angitte overflateaktive materialer i de foreliggende tannpleiepreparater. where R is a fatty alkyl group containing approx. 12-18 carbon atoms and x, y and z together 3 or higher, and salts thereof with mineral acids or organic acids can also be used. It is preferred to use 0.05-5% by weight of the above-mentioned surface-active materials in the present dental care preparations.
De relative poleringsegenskaper for det krystallinske siliciumdioxyd med foreskjellige gjennomsnittlige partikkelstorrelser ble undersokt på dentin fra trukkede tenner. The relative polishing properties of the crystalline silicon dioxide with different average particle sizes were investigated on dentin from extracted teeth.
Forskjellige prosenter eller mengder av en rekke typer av krystallinsk siliciumdioxyd med partikkelstorrelser, gjennomsnittlige partikkelstorrelser og overflatearealter som angitt i tabellene I og II ovenfor, ble satt til et tannpleiemiddel med folgende sammen-setning : Different percentages or amounts of a variety of types of crystalline silicon dioxide with particle sizes, average particle sizes and surface areas as indicated in Tables I and II above were added to a dentifrice with the following composition:
De oppnådde resultater ble avsatt på kurver, og de fra kurvene oppnådde verdier for poleringsevene er angitt i tabell III nedenfor. The results obtained were plotted on curves, and the values obtained from the curves for the polishing properties are given in Table III below.
Et kosmetisk aksepterbart tannpleiepreparat skal inneholde minst 30% av poleringsmidlet. Dessuten bor poleringsmidlet ha en poleringsevne av minst ca. 2h- 0 enheter og ikke over ca. 350 for at det ikke skal gi en for liten eller for sterk polering. Denne ovre grense for poleringsevne kan aksepteres. Naturlig forekommende krystallinske silikater har en for sterk poleringsevne til at' de kan aksepteres i tannpleiepreparater. Det fremgår av resultatene i tabell III at når det krystallinske siliciumdioxyd har en gjennomsnittlig partikkelstorrelse av 1,1 jum og anvendes i en mengde av 30 vekt% eller derover av tannpleiepreparatet, -oppnås en onskelig polering. Dette, er spesielt tilfelle dersom det krystallinske siliciumdioxyd er tilstede i tannpleiemidlet i en mengde fra noe under h0% inntil noe over 50% da en poleringsevne av 275~325 enheter, spesielt 3OO5 er meget onskelig. Kvaliteter av krystallinsk siliciumdioxyd med en gjennomsnittlig partikkelstorrelse under 1,1 jum og et overf lateareal av inntil 50.000 cm.<2>/g hai" også en onskelig poleringsevne innen et vidt område for innholdet av poleringsmiddel i et tannpleiemiddel. A cosmetically acceptable dental care preparation must contain at least 30% of the polishing agent. In addition, the polishing agent must have a polishing ability of at least approx. 2h- 0 units and no more than approx. 350 so that it does not give too little or too strong a polish. This upper limit of polishing ability can be accepted. Naturally occurring crystalline silicates have too strong a polishing ability for them to be accepted in dental care preparations. It appears from the results in Table III that when the crystalline silicon dioxide has an average particle size of 1.1 µm and is used in an amount of 30% by weight or more of the dental care preparation, a desirable polishing is achieved. This is especially the case if the crystalline silicon dioxide is present in the dentifrice in an amount from slightly below h0% to slightly above 50% as a polishing ability of 275~325 units, especially 3OO5 is very desirable. Grades of crystalline silicon dioxide with an average particle size below 1.1 µm and a surface area of up to 50,000 cm.<2>/g hai" also have a desirable polishing ability within a wide range for the content of polishing agent in a dentifrice.
De kvaliteter av krystallinsk siliciumdioxyd som har en gjennomsnittlig partikkelstorrelse av ^,19 Mm og 2,70 ^m, har ikke en onskelig poleringsevne, mens det krystallinske siliciumdioxyd som har en gjennomsnittlig partikkelstorrelse av 2,06 ^m, har en effektiv poleringsevne i en konsentrasjon over 30% av tannpleiepreparatet bare innen et snevert område som slutter ved 3^,3% av tannpleiepreparatet. Mindre mengder av disse kvaliteter av krystallinsk siliciumdioxyd eller av andre poleringsmidler kan selvfolgelig anvendes sammen med krystallinsk siliciumdioxyd med en gjennomsnittlig partikkelstorrelse av inntil 1,1 ^m, partikler med en storrelse av inntil 5 M™ og et overflateareal av inntil 50„000 cm /g for å modifisere poleringsevnene efter or. ske. Tannpleiepreparatet kan med andre ord som poleringsmiddel inneholde en hovedsakelig mengde (25 vekt% av tannpleiepreparatet) av krystallinsk siliciumdioxyd av kvalitet "n" ifolge tabell III med en poleringsevne av ca. 215 enheter, og en mindre mengde (f.eks. 20 vekt% av tannpleiepreparatet) av et annet poleringsmiddel for fremstilling av et tannpleiepreparat med en poleringsevne av ca0 300 enheter. The grades of crystalline silicon dioxide having an average particle size of ^.19 µm and 2.70 µm do not have a desirable polishing ability, while the crystalline silicon dioxide having an average particle size of 2.06 µm has an effective polishing ability in a concentration above 30% of the dental care preparation only within a narrow range ending at 3^.3% of the dental care preparation. Smaller amounts of these qualities of crystalline silicon dioxide or of other polishing agents can of course be used together with crystalline silicon dioxide with an average particle size of up to 1.1 µm, particles with a size of up to 5 M™ and a surface area of up to 50,000 cm / g to modify the polishing abilities according to or. happen. In other words, the dental care preparation can contain as a polishing agent a mainly amount (25% by weight of the dental care preparation) of crystalline silicon dioxide of quality "n" according to table III with a polishing ability of approx. 215 units, and a smaller amount (e.g. 20% by weight of the dental care preparation) of another polishing agent for the production of a dental care preparation with a polishing power of approx. 300 units.
Ifolge visse utforelsesformer av oppfinnelsen anvendes kationaktive antibakterielle midler i de foreliggende preparater. Disse midler omfatter: N1- (^-klorbenzyl )-5f^- (2 ,^-dIklorbenzyD-big^anid, p-klorfenylbiguanid, According to certain embodiments of the invention, cationic antibacterial agents are used in the present preparations.

og deres ugiftige syreaddisjonssalter,spesielt fluoridene og dihydrogenfluoridene. 1,6-di-(p-klorfenylbiguanidhexan)er spesielt foretrukket. Disse midler kan anvendes i en mengde av .0,01 -5 vekt %, fortrinnsvis '.0,05-1 vekt %,av tannpleiepreparatet. and their non-toxic acid addition salts, especially the fluorides and dihydrogen fluorides. 1,6-di-(p-chlorophenylbiguanidehexane) is particularly preferred. These agents can be used in an amount of 0.01-5% by weight, preferably 0.05-1% by weight, of the dental care preparation.
De kationaktive antibakterielle midler er blitt anvendt i kjente tannpleiepreparater. Disse midler har gitt slike preparater antibakteriell virkning. Denne virkning har imidlertid ofte vært noe begrenset, og dette skyldes muligens tilstedeværelsen av storre mengder ioniske poleringsmidler i slike tannpleiepreparater. Disse poleringsmidler er i det vesentlige vannuopplbselige, men de har noen vannopploselighet som kan begrense virkningen av de kationaktive antibakterielle midler. The cationic antibacterial agents have been used in known dental care preparations. These agents have given such preparations antibacterial action. However, this effect has often been somewhat limited, and this is possibly due to the presence of large amounts of ionic polishing agents in such dental care preparations. These polishing agents are essentially water insoluble, but they have some water solubility which can limit the effect of the cationic antibacterial agents.
Ifolge oppfinnelsen utgjores poleringsmaterialet i det minste av en hovedsaklig del av et spesielt krystallinsk siliciumdioxyd som er ikke-ionisk. Poleringsmidlet gir derfor ikke noen vesentlig, mengder av anionisk materiale som kan hindre virkningen av According to the invention, the polishing material is made up of at least a substantial part of a special crystalline silicon dioxide which is non-ionic. The polishing agent therefore does not provide any significant amounts of anionic material that can prevent the effect of
de antibakterielle midler. Det har således spesielt vist seg at et tannpleieapparat inneholdende 0,50 % 1,6-di-(p-klor-fenylbiguanid-hexan)og k-^ % siliciumdioxyd med partikler med en storrelse inntil 5jLim,en gjennomsnittlig partikkelstorrelse av 1,1/Um og et overflateareal av 20.600 cm /g ga en 35 % minskning av tannstendannelsen hos rotter som var blitt foret med en tannstendannende diet,sammen-lignet med et kcntrolltannpleiepreparat uten det antibakterielle middel. Dette viser de sterke antibakterielle virkninger til det kationaktive antibakterielle middel i tannpleiepreparatet inneholdende ikke- the antibacterial agents. It has thus been particularly shown that a dental care device containing 0.50% 1,6-di-(p-chloro-phenylbiguanide-hexane) and k-^% silicon dioxide with particles with a size of up to 5 µm, an average particle size of 1.1 /Um and a surface area of 20,600 cm /g produced a 35% reduction in calculus formation in rats fed a calculus-forming diet compared to a control dental care preparation without the antibacterial agent. This shows the strong antibacterial effects of the cationic antibacterial agent in the dental care preparation containing non-
ionisk, krystallinsk siliciumdioxyd. Det er også onskelig å anvende salter, som gluconatet eller acetatet av l,6-di-(p-klor-fenylbiguanidhexan). ionic crystalline silicon dioxide. It is also desirable to use salts, such as the gluconate or acetate of 1,6-di-(p-chloro-phenylbiguanidehexane).
Det er dessuten onskelig at preparatene ifolge oppfinnelsen inneholdende poleringsmidlet av ikke-ionisk, krystallinsk siliciumdioxyd inneholder en fluorholdig forbindelse med gunstig virkning for pleien av og hygienen i munnhulen, f.eks. minskning av opp-loseligheten av emalje i syre og beskyttelse av tennene mot ned-brytning. Eksempler på,disse omfatter natriumfluorid, toverdig tinnfluorid, kalsiumfluorid, kalsiumtinnfluorid (SnF2-KF) og toverdig tinnklorfluorid. Det er gunstig at disse materialer som spalter eller avgir fluorholdige ioner, er tilstede i en effektiv, men ugiftig, mengde av som regel 0,01-1 vekt% av deres innhold av vannopploselig fluor. Natriumfluorid og toverdig tinnfluorid er spesielt foretrukne, og dessuten blandinger derav. It is also desirable that the preparations according to the invention containing the polishing agent of non-ionic, crystalline silicon dioxide contain a fluorine-containing compound with beneficial effects for the care and hygiene of the oral cavity, e.g. reduction of the solubility of enamel in acid and protection of the teeth against decay. Examples of these include sodium fluoride, divalent stannous fluoride, calcium fluoride, calcium stannous fluoride (SnF2-KF) and divalent stannous chlorofluoride. It is advantageous that these materials which split or emit fluorine-containing ions are present in an effective, but non-toxic, amount of typically 0.01-1% by weight of their water-soluble fluorine content. Sodium fluoride and divalent stannous fluoride are particularly preferred, and also mixtures thereof.
De i de efterfolgende eksempler angitte preparater ifolge oppfinnelsen ble fremstilt på vanlig måte, og alle mengder og forhold er basert på vekt dersom intet annet er angitt. The preparations according to the invention stated in the following examples were prepared in the usual way, and all amounts and ratios are based on weight if nothing else is stated.
