Description

An oily composition for oral health care, its preparation method and its application

technical field

The invention belongs to the technical field of oral care, and relates to an oily composition for oral health care, a preparation method and application thereof.

Background technique

The oral cavity is the starting point of the two major systems of the human respiratory system and the digestive system. Oral health is closely related to the health of the whole body. It not only directly affects the quality of people's daily life, but also may be the culprit of diseases in other parts of the body such as the heart, stomach, and lungs. .

In order to ensure oral health, people have long used mouthwash to remove food residues and some loose soft scales, as well as dirt and odors that are easily removed by the force of gargling. Rinsing with a mouthwash can help reduce disease-causing microorganisms or inhibit the growth of bacteria in the mouth. Later, with the improvement of people's requirements for oral care, oral care products such as toothpaste, tooth cleaning powder, and oral spray appeared. In order to improve the efficacy, oral fresheners, such as menthol and eucalyptus oil, are added to current oral care products to remove bad breath. Toothpastes are often added with fungicides such as dioxophenylbiguanidyl hexane and ciprofloxacin, copper leaf Chloric acid also has a certain effect on preventing bad breath; adding alcohol, surfactants, etc. to help dissolve the dirt, alcohol has a solubilizing effect on fat-soluble components, and also has a certain bactericidal effect. The currently widely used surfactant is laurel Sodium alcohol sulfonate; various bacteriostatic agents are added; some drugs are added in low doses for curative effect, such as triclosine, metronidazole, tinidazole and chlorhexidine. It is true that the addition of the above additives can improve the effect of oral care to a certain extent, but the above additives are mostly chemical additives, and some substances with medicinal effects will cause a series of side effects such as dry mouth, oral flora imbalance, and damage to the oral mucosa. There are also problems such as tooth surface coloration, dysgeusia, and dysbacteriosis. At the same time, the latest research shows that mouthwash contains a lot of alcohol, and if it is used more than three times a day, it will increase the risk of oral cancer.

In order to overcome the defects of the current oral care products, CN 201710702547.X discloses an oral care composition, which, by mixing various base oils to reconcile the mouthfeel, avoids the situation of poor mouthfeel experience of a single oil, and simultaneously balances the intake of fatty acids, Improve the absorption rate, but they are all base oils, although they have a certain oral cleaning ability, but the effect is not good; CN201710083315.0 discloses a kind of oral care essential oil, which mixes sweet almond oil with peppermint essential oil and spearmint essential oil It is prepared into an oily care solution. Although it can effectively kill harmful bacteria and has the functions of anti-inflammatory, analgesic, clearing breath and protecting gums, the total essential oil ratio of the care solution reaches 45-65%, which is far higher than the safety of essential oils. The scope of use has a strong stimulating and destructive effect on the oral mucosa, and the currently used method of preparation is complicated, and the convenience of use is poor.

Therefore, it is of great practical significance to develop an oral care additive composition with good oral cleaning effect, natural non-irritant, soft taste and high safety.
