Description

Novel mouthwash and preparation method thereof

Technical Field

The invention belongs to the technical field of oral care products, and particularly relates to novel mouthwash and a preparation method thereof.

Background

Oral inflammatory disease is a common and frequently occurring disease, and almost everyone experiences oral inflammatory disease. Common oral inflammatory diseases include canker sores, gingivitis, periodontitis, halitosis, and the like.

The current method for preventing and treating the oral inflammatory diseases mainly comprises the steps of chemical mouthwash rinsing and traditional Chinese medicine extract mouthwash rinsing. The chemical gargle contains povidone iodine, chlorhexidine acetate, cetylpyridinium chloride, tinidazole and other components, has a strong and broad-spectrum sterilization effect, but has poor taste, large irritation to mucous membrane, easy discomfort and possibility of causing the imbalance of normal flora of the oral cavity after long-term use. The traditional Chinese medicine extract mouthwash contains many components such as clove, astragalus root, honeysuckle, senecio scandens, bupleurum, liquorice and the like, has a certain effect on keeping the oral cavity clean and preventing oral infection, but the mouthwash containing the traditional Chinese medicine extract has a deep color, can cause tooth staining when being frequently used, and has more complex components, so that the problems of turbidity, precipitation, reduced efficacy and the like of the mouthwash in the storage process are easy to occur.

Aiming at the problems of large side effect, uncomfortable use, unstable efficacy and the like of the existing mouthwash, the need for searching the mouthwash with small side effect, stable efficacy and comfortable taste is urgent, and the public demand is met while the good mouth protection effect is achieved.

Disclosure of Invention

The invention aims to provide novel mouthwash and a preparation method thereof. The mouthwash has the advantages of safe and nontoxic components, low irritation, excellent effects of sterilizing, diminishing inflammation, promoting wound healing and whitening teeth, can effectively prevent and treat various oral inflammatory diseases, and is a novel multifunctional oral care product.

The invention is realized by the following technical scheme:

the novel mouthwash consists of the following components in percentage by mass: 0.5 to 1.5 percent of aluminum cloxate, 1 to 5 percent of glucose oxidase, 1 to 3 percent of allantoin biotin salt, 4 to 8 percent of bamboo salt, 3 to 5 percent of 3-O-ethyl ascorbyl ether, 0.1 to 0.3 percent of lemon peel powder and sclerotium rolfsii, 4 to 8 percent of humectant, 0.5 to 1 percent of solubilizer, 0.1 to 0.5 percent of edible essence and the balance of deionized water.

Preferably, the novel mouthwash consists of the following components in percentage by mass: 1% of aluminum cloxate, 4% of glucose oxidase, 2% of allantoin biotin salt, 6% of bamboo salt, 4% of 3-O-ethyl ascorbyl ether, 0.2% of lemon peel powder and sclerotium rolfskin, 6% of humectant, 1% of solubilizer, 0.5% of edible essence and the balance of deionized water.

Preferably, the humectant is one or any combination of glycerin, xylitol and sorbitol.

More preferably, the humectant is glycerin.

Preferably, the solubilizer is PEG-40 hydrogenated castor oil or polysorbate.

More preferably, the solubilizing agent is PEG-40 hydrogenated castor oil.

Preferably, the edible essence is green tea essence, lemon essence, sweet orange essence or peppermint essence.

The preparation method of the novel mouthwash comprises the following steps:

(1) Dissolving a solubilizer in part of water according to a formula, adding allantoin biotin salt, edible essence and a humectant under stirring, and stirring for 10-20 min to obtain an aqueous solution;

(2) Dissolving bamboo salt and 3-O-ethyl ascorbyl ether in the rest water according to a formula, adding aluminum cloxate, glucose oxidase, lemon peel powder and sclerotium rolfsii, stirring for 10-20 min, then adding the mixture into the aqueous solution obtained in the step (1), and stirring for 10-20 min to obtain the mouthwash.

The novel mouthwash has excellent effects of sterilizing, diminishing inflammation and promoting wound healing, and can be used for preparing products for preventing and treating oral inflammatory diseases.

The aluminum cloxate and the bamboo salt in the formula are used as bactericides, and the synergistic antibacterial activity of the aluminum cloxate and the bamboo salt is better than the antibacterial activity of pathogenic bacteria causing oral inflammation, such as porphyromonas gingivalis, actinomyces viscosus and staphylococcus aureus when the aluminum cloxate and the bamboo salt are used singly. The allantoin biotin salt has the effect of promoting cell growth, and the 3-O-ethyl ascorbate ether has the effect of promoting skin mucosa tissue repair and promoting collagen biosynthesis in cells, and the allantoin biotin salt and the 3-O-ethyl ascorbate ether have the effect of promoting wound healing under the convergence effect of aluminum cloxate. The glucose oxidase can catalyze glucose to generate glucolactone and hydrogen peroxide, and has effects of preventing dental caries and whitening teeth. The interaction of the above components in the mouthwash plays remarkable roles of sterilizing, diminishing inflammation, promoting wound healing and whitening teeth, and can effectively prevent and treat various oral inflammatory diseases including oral ulcer, gingivitis, periodontitis, halitosis and the like.

The formulation of the mouthwash of the present invention is not a simple combination of any of the functional ingredients. The stability of the glucose oxidase and the allantoin biotin salt in the formula is poor, the compatibility problem exists between the glucose oxidase and the allantoin biotin salt and the bamboo salt, and the alkalinity of the bamboo salt can promote the inactivation of the glucose oxidase and the decomposition of the allantoin biotin salt. And hydrogen peroxide released by glucose oxidase in decomposing sugar in the oral cavity also reduces the enzyme activity. The inventor unexpectedly found that when a proper amount of 3-O-ethyl ascorbate ether is contained in the system, the stability of glucose oxidase and allantoin biotin salt can be improved, the oxidation resistance of the 3-O-ethyl ascorbate ether can resist the influence of hydrogen peroxide on enzyme, and the proper acidity can neutralize the alkalinity of bamboo salt, so that the decomposition of the allantoin biotin salt is inhibited, and the enzyme activity is improved. The formula is added with a small amount of lemon peel powder and sclerotium rolfsii (fiber design) ^TM Sensing) improves the mouth feel of the mouthwash on the one hand and the adhesion of the enzyme on the other hand, so that the enzyme can attach to teeth to continuously react.

Compared with the prior art, the invention has the following beneficial effects:

1. the mouthwash disclosed by the invention has excellent effects of sterilizing, diminishing inflammation, promoting wound healing and whitening teeth, can effectively prevent and treat various oral inflammatory diseases, and is a novel multifunctional oral care product.

2. The mouthwash disclosed by the invention is safe and nontoxic in each component, low in irritation and wide in applicable crowd.

3. The mouthwash disclosed by the invention is stable in property, comfortable in taste and easy to accept by people.

Detailed Description

The following examples are further illustrative of the invention and are not intended to be limiting thereof. The components of the formulations in the examples below, unless otherwise specified, are all conventional commercial products.

Examples 1-5 preparation of novel mouthwashes

The formulations of the novel mouthwashes of examples 1-5 of the present invention are shown in table 1 below (in mass percent):

TABLE 1 formulation composition

The preparation method comprises the following steps:

(1) Dissolving PEG-40 hydrogenated castor oil in part of water according to a formula, adding allantoin biotin salt, green tea essence and glycerol under stirring, and stirring for 15min to obtain an aqueous solution;

(2) Dissolving bamboo salt and 3-O-ethyl ascorbyl ether in the rest water according to a formula, adding aluminum cloxate, glucose oxidase, lemon peel powder and sclerotium rolfsii, stirring for 15min, then adding the mixture into the aqueous solution obtained in the step (1), and stirring for 10min to obtain the mouthwash.

Comparative example 1

Comparative example 1 differs from example 1 in that 3-O-ethyl ascorbate was not added to the formulation.

Comparative example 2

Comparative example 2 differs from example 1 in that no bamboo salt was added to the formulation.

Comparative example 3

Comparative example 3 differs from example 1 in that 3-O-ethyl ascorbate and bamboo salt were not added to the formulation.

Comparative example 4

Comparative example 4 differs from example 1 in that no aluminum cloxate was added to the formulation.

Test example one, toxicology test

The novel mouthwashes of examples 1-5 and comparative examples 1-4 were tested according to the acute oral toxicity test of the disinfection technical Specification, and evaluated for their toxic effects by the subject animal LD 50. The results show that: the acute oral toxicity test results for the mouthwashes of examples 1-5 and comparative examples 1-4 were: the LD50 is more than or equal to 5000mg/kg. Therefore, the mouthwash provided by the invention is safe, nontoxic and nonirritating, and is suitable for various people.

Test example two, antibacterial Activity and enzyme Activity detection

1. The antibacterial activity of the novel mouthwashes of examples 1 to 5 and comparative examples 1 to 4 against Porphyromonas gingivalis (ATCC 33277), actinomyces viscosus (ATCC 27044) and Staphylococcus aureus (ATCC 6538) was examined by referring to "evaluation method of antibacterial and bacteriostatic effect of QBT 2738-2012 daily chemical products", and the antibacterial rate after 60 minutes of the action was recorded, and the results are shown in Table 2.

TABLE 2 antibacterial Activity detection results

The results show that the novel mouthwash prepared in examples 1-5 has good antibacterial activity on porphyromonas gingivalis, actinomyces viscosus and staphylococcus aureus, and the effect is better than that of the mouthwash prepared in comparative examples 1-4. As is clear from comparative example 1, the formulation does not contain 3-O-ethyl ascorbyl ether and hardly affects the antibacterial activity of the mouthwash. As can be seen from comparative examples 2 and 4, the formula without bamboo salt or aluminum cloxate can obviously reduce the antibacterial activity of the mouthwash, and the antibacterial effect of the formula with single use is obviously inferior to that with simultaneous use, which indicates that the bamboo salt and the aluminum cloxate exert synergistic antibacterial effect.

2. The activity of glucose oxidase in the novel mouthwashes of examples 1-5 and comparative examples 1-4 was tested by referring to "spectrophotometry for measuring the activity of glucose oxidase of feed additive, DB 41/T1729-2018", and the mouthwashes were diluted 500 times with deionized water before measurement; the activity (U/mg) of glucose oxidase was measured at 0, 12 and 24 months, respectively, and the enzyme activity retention rate after 12 and 24 months was calculated.

After 12 months, the enzyme activity retention = (1- (0 month enzyme activity value-12 month enzyme activity value)/0 month enzyme activity value) ×100%.

After 24 months, the enzyme activity retention = (1- (0 month enzyme activity value-24 month enzyme activity value)/0 month enzyme activity value) ×100%.

The results are shown in Table 3.

TABLE 3 glucose oxidase Activity detection results

Group of	Enzyme activity retention after 12 months (%)	Enzyme activity retention after 24 months (%)
			Example 1	99.4	96.5
Example 2	99.2	95.8
			Example 3	99.0	95.0
Example 4	99.6	97.2
			Example 5	99.3	96.0
Comparative example 1	5.7	/
			Comparative example 2	94.8	82.6
Comparative example 3	99.3	96.4
			Comparative example 4	99.4	96.4

The results show that the novel mouthwashes prepared in examples 1-5 are stored for 2 years at room temperature, and the activity of glucose oxidase is reduced little, which indicates that the mouthwash system is stable and can effectively maintain the activity of glucose oxidase. As is clear from comparative example 1, the formulation does not contain 3-O-ethyl ascorbate, and the glucose oxidase activity is rapidly reduced, presumably due to rapid inactivation of glucose oxidase caused by the strong basicity of bamboo salt. As is clear from comparative example 2, the formulation does not contain bamboo salt, and the glucose oxidase activity is lowered, presumably due to slow inactivation of glucose oxidase caused by the acidity of 3-O-ethyl ascorbate. As is clear from comparative example 3, the formulation does not contain 3-O-ethyl ascorbate and bamboo salt, and hardly affects the activity of glucose oxidase. As is clear from comparative example 4, the activity of glucose oxidase was hardly affected by aluminum cloxate in the formulation. The above results indicate that the interaction of 3-O-ethyl ascorbate and bamboo salt helps to maintain glucose oxidase activity.

Test example III, evaluation of gingivitis control Effect

The random double-blind control experiment design is characterized in that 54 volunteer subjects suffering from gingivitis symptoms with different degrees are collected, 9 groups are randomly arranged, 6 persons in each group are respectively used for preparing the novel mouthwash by using the examples 1-5 and the comparative examples 1-4, and the use times are once in the morning, the evening and the evening every day, and the novel mouthwash is continuously used for 4 weeks. The gum index of volunteer subjects after 4 weeks of mouthwash use was examined using the method of oral epidemiological investigation. Gum Index (GI): checking the situation of 4 areas of gingival margin in mesial, distal, buccal and lingual areas, wherein the 4 areas are classified into 0-3 level standard and 0 point (normal gingival); score 1 (low inflammation of gums, low change in color, low edema, no bleeding in visit); 2 minutes (moderate inflammation of gum, reddish, edema, bright, bleeding visit); 3 minutes (obvious gingivitis, redness and swelling, ulceration, tendency to automatic bleeding), average. The results are shown in Table 4.

TABLE 4 evaluation results of gingivitis control Effect

The results show that the novel mouthwashes prepared in examples 1-5 are effective in treating gingivitis and have better effects than the mouthwashes prepared in comparative examples 1-4.

The foregoing is merely a preferred embodiment of the present invention, and it should be noted that the above-mentioned preferred embodiment should not be construed as limiting the invention, and the scope of the invention should be defined by the appended claims. It will be apparent to those skilled in the art that various modifications and adaptations can be made without departing from the spirit and scope of the invention, and such modifications and adaptations are intended to be comprehended within the scope of the invention.
