Mouthwash tablet containing plant extract and preparation method thereof

technical field

The invention relates to the field of oral care products, in particular to a mouthwash tablet containing plant extracts and a preparation method thereof.

Background technique

A beautiful and bright white teeth can add a lot to personal image, but dental disease also plagues many people, especially dental caries seriously affects people's image, social interaction and physical health.

There are many products on the market to help users maintain oral health. Common products include toothpaste, chewing gum, mouthwash, and breath fresheners, which can play a positive role in oral health by cleaning teeth, eliminating bad breath, and killing bacteria. therapeutic and health effects.

However, the above products also have certain defects. Toothpaste is the most widely used tooth cleaning product with the best cleaning efficiency, but it has the problems of large size and inconvenient portability; chewing gum can clean teeth and eliminate bad breath. It has no killing effect on tooth bacteria; breath fresheners have bactericidal and non-bacterial types, which can clean breath, but cannot effectively clean teeth; mouthwash is easy to carry, can clean teeth, eliminate breath, and kill bacteria. Widespread, but a leak of liquid mouthwash may soak other important items, causing irreparable damage.

In view of this, some manufacturers on the market have begun to develop and manufacture mouthwash tablets, which have the functions of cleaning teeth, eliminating bad breath, and killing bacteria, and are easy to carry. The solid form avoids the possibility of leaking and soaking other items.

But the use mode of this entrance-type dispersible mouthwash tablet is to contain clear water mouthwash again by being included in the mouthwash tablet, and this mouthwash tablet contains more foaming cleansers, film-forming agents, and they can quickly absorb the oral cavity Moisture will dry the mouth in a short time, and even damage the oral mucosa. In addition, too much plasticizer will also cause damage to human liver, kidney, and reproductive functions, and is mutagenic and carcinogenic.

CN201010220670 provides a mouthwash preparation containing nystatin, which can be made into preparations in the form of mouthwash tablets, effervescent tablets, dispersible tablets, granules, buccal tablets, etc., and the nystatin ingredients contained are used for prevention and treatment Oral fungal infection. The nystatin used in this preparation is a broad-spectrum antifungal drug. Its product function is mainly used as a pharmaceutical product, which is made for oral fungal infection. Daily long-term use will cause the imbalance of oral flora, so it cannot be used as daily oral cleaning care .

CN200810103364 provides a synergistic nystatin-menthol composition, the most preferred way of making dosage form is mouthwash tablet, the nystatin component contained is used to prevent and treat oral fungal infection, and the proportion of nystatin and menthol is configured A good synergistic therapeutic effect can be obtained. But equally, the main function of this preparation is as a pharmaceutical product, and the broad-spectrum antifungal drug nystatin makes this product unsuitable for daily oral cleaning care.

CN200580048793 provides a method of using magnolia extract to reduce oral tissue inflammation, using magnolia's natural anti-inflammatory active ingredients to reduce one or more verified mediators to reduce inflammation in oral tissue. The natural anti-inflammatory active ingredient of magnolia extract is safe, effective and non-irritating. The composition can be produced in the form of toothpaste, gel, powder, lozenge, etc., but does not provide a specific method for making a portable oral cleaning product.

CN95104632.2 provides a kind of coral coral mouthwash, by prefabricating the coral coral extract, then mixing natural peppermint oil, Tween-80, 95% edible ethanol, and medicinal glycerin in the weight ratio, adding the coral coral extract, Additives and distilled water were stirred to prepare mouthwash. This product is also in liquid state and not easy to carry.
