The invention relates to novel chemical mixtures for mouth care, gum care and den¬ tal care containing aluminium and ferric salts, to processes for their preparation and their use.
The invention particularly relates to novel chemical mixtures characterized in that they contain aluminium ammonium sulphate or aluminium potassium sulphate or a mixture of aluminium ammonium sulphate and aluminium potassium sulphate or a mixture of aluminium ammonium sulphate, aluminium potassium sulphate and ferric ammonium sulphate or a mixture of aluminium ammonium sulphate and ferric am¬ monium sulphate or a mixture of aluminium potassium sulphate and ferric am¬ monium sulphate and/or boric acid and appropriate humectants, ethanol, sodium fluoride, a flavouring component, a non-ionic tenside and water.
Solutions for oral care and gum care and pastes for dental care described in the in¬ vention have pronounced deodorant, astringent and disinfectant properties.
A particular advantage of the products described in the invention is that due to the excellent choice of the flavour as breath freshener bad breath is removed effectively and for a longer period of time.
A further effect of the chemical mixtures described in this invention is their astrin¬ gent action on the mouth mucosa and thus by rinsing the mouth all waste plaque sub¬ stances are eliminated. At the same time direct causes of dental and gum diseases are diminished.
An important advantage of the solutions of the present invention is their potent dis¬ infectant action. It is shown in their bactericidal activity since they reduce bacterial flora in the mouth and inhibit bacterial enzymes converting sugars into acids.
In the literature there have not been described the preparation and use of washes and pastes for mouth care, gum care and dental care with excellent refreshing and protective properties containing a mixture of aluminium ammonium sulphate or a mixture of aluminium ammonium sulphate with aluminium potassium sulphate and ferric ammonium sulphate in various combinations.
It is very well known that, due to their specific properties, various alums and sulphate salts are used in preparations for dental and oral hygiene.
It is known that aluminium salts and various sulphates have excellent deodorant, astringent and pronounced bactericidal and fungicidal properties.
In the literature there are described numerous preparations or washes for mouth care and dental care which contain alums or sulphate salts as an active ingredient. Thus in the literature there is described an anti-caries dental agent or emulsion for rinsing the mouth containing potassium aluminium sulphate dodecahydrate and cor¬ responding tensides and humectants (EP-A-270 977 of 15.06.1988, Chem. Abstr. 110 (1989) 198967 b).
In many patents also the use of sulphate salts as active components in mouthwashes is described. So there is described a mouthwash for removing bad breath containing a zinc salt (Zn-sulphate) and an appropriate emulsifying agent (EP-A-251 542 of 07.01.1988, Chem. Abstr. 108 (1988) 101135 b). In 1991 a chemical mixture for dental hygiene was described, which was used for the treatment of dental diseases and gin¬ givitis and contained 16% of calcium sulphate, ethanol, glycerin and water (WO 91/99168 of 08.08.1991, Chem. Abstr. 115 (1991) 142051 j). For prevention of periodontosis an oral composition prepared from ferric sulphate is described (JP 90/164,815 of 25.06.1990, Chem. Abstr. 113 (1990) 170854 k).
In the literature also the testing of different gargle solutions is described (Yakuziagaku 17, (1957) 134-6, Chem. Abst. 52 (1958) 11275 b). Gargle solutions had the following compositions:
Solution I contained: alum 1.5 g menthol solution 25.0 g water 500 ml
Solution II contained: hydrogen peroxide 0.12 %
Solution III contained: sodium chloride 5.0 g sodium hydrogen carbonate 50.0 g water 500 ml
Solution IV contained: boric acid 2 %
Solution V contained: sodium peroxyborate 0.54 %
Solution VI contained:
Rivanole 0.25 g boric acid 20 g water 1000 ml
The activity of the solutions decreased in the following order: I> V> VI > III > II > IV. Their inhibitory activity against Bacillus subtilis and Saccharomyces albicans was tested. The activity of the gargle solution was tested in the following order:
1. B. subtilis
2. 2x dilution
3. 4x dilution
4. S. albicans
5. 2x dilution
6. 4x dilution
The results for the solution I were as follows: 1 2 3 4 5 6 +
The present invention relates to novel refreshing and antiseptic chemical mixtures for mouth care, gum care and dental care containing as active components aluminium ammonium sulphate, aluminium potassium sulphate and ferric am¬ monium sulphate and/or boric acid and ethanol, glycerin, sodium fluoride, a flavour¬ ing component, an appropriate tenside, a colour and water.
An advantage of the solutions and pastes for oral hygiene, dental hygiene and gum treatment described in the present invention is that by their use bad breath is removed for a longer period of time.
By using the described mixtures consequences of microbicidal processes in the mouth cavity are prevented and removed. By their regular use the pathomorphologic decay of hard tooth substances and thereby the possibility of dental caries are reduced.
By the use of oral hygiene preparations of the invention the formation of plaque and tartar and the deposition thereof on tooth necks and gums are prevented, whereby the possibility of gingivitis is reduced.
There are different reasons for bad breath. It may be produced from tonsillitis and diseases of esophagus or stomach. However, most frequently bad breath is caused by food debris after a meal. Food debris disintegrated by saliva and bacteria cause bad breath since from proteins, carbohydrates and fats ammonia, amines, hydrogen sul¬ fide, mercaptans and various aldehydes and ketones are formed.
Food debris after a meal also cause plaque to accumulate on teeth. The plaque mainly consists of organic disintegration products which are a good culture medium for bacteria, which by enzymatic disintegration of calcareous substances from saliva produce tartar. In this process also microorganisms belonging to lactobacteria as well as some other bacteria take part.
Tartar is deposited on tooth necks and can cause gum inflammation or gingivitis. At the same time tartar is one of the causes for periodontosis since by the deposition thereof the gum tissue becomes unprotected, more sensitive and easily inflammable. Beside dental caries periodontosis is the most frequent dental disease. Dental caries is caused by pathomorphologic decay of tooth enamel and dentin. Biochemically, this is an enzymatic dissolution of hard tooth parts caused by phosphatases, oxidases and proteases of bacteria in the mouth and by the influence of saliva. The reasons there-
for are the diet, hormonal-vegetative anomalies, genetic factors and consequences of various diseases. Lack of vitamins in the diet and disturbances in the organism also increase periodontosis.
The object of the present invention are novel chemical mixtures for mouth care, gum care and dental care and solutions and pastes intended for general oral hygiene after cleaning one's teeth. The described preparations also diminish direct causes of dental and gum diseases and satisfy the following basic conditions:
they prevent the development of bacteria, reduce bacterial flora in the mouth and thereby the consequences of bacterial fermentation of food debris in the mouth, they prevent the coating of the teeth by dentobacterial plaque and the accumula¬ tion of organic disintegration products on the teeth, they prevent the calcification of the plaque into tartar and enzymatic disintegra¬ tion of calcareous substances from saliva and the formation of dental calculus (tartar), they prevent the deposition of tartar on tooth necks and thereby directly prevent the causes of periodontosis, they prevent the deposition of plaque on tooth necks and thereby directly prevent the hypersensibility of gum tissue and the causes of gingivitis, they prevent or immediately stop gum bleeding, they prevent or soothe all inflammatory processes of the gums, they prevent the enzymatic dissolution of hard tooth parts, demineralization of enamel and formation of dental caries; they are characterized in that they contain aluminium ammonium sulphate dodecahydrate acting in a bactericide and astringent manner, they are characterized in that that they contain aluminium potassium sulphate dodecahydrate acting in a microbicide and astringent manner, are characterized in that they contain ferric ammonium sulphate dodecahydrate acting in a fungicide and astringent manner, they are characterized in that they contain an appropriate humectant, glycerin and tenside, they are characterized in that they contain sodium fluoride and boris acid, they are characterized in that they contain sodium monofluoro phosphate, sac¬ charin, phosphates, silicates and paraffin oil, they are characterized in that they contain an appropriate breath freshener,
