Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention is convenient for carrying, does not require combined use with a toothbrush, and rubs directly on the tooth surface and then gargles lightly to clean the teeth. The present invention relates to a solid dentifrice that can be used, more specifically, to a solid dentifrice that contains an abrasive, a foaming agent, and a wetting agent, and is solidified by physical pressure molding without or with addition of a binder. .

(Prior Art) Toothpastes have been conventionally used for preventing tooth decay and cleaning teeth. Toothpaste generally contains abrasives, foaming agents, binders, wetting agents, sweeteners, flavoring agents, preservatives and, if necessary, medicinal ingredients as basic components, and powder toothpaste depending on the content of the abrasive. , Toothpaste, and moisturizing toothpaste, and there is a water-based dentifrice containing no abrasive as a special form. All of these dentifrices are stored in a container and are used by being attached to a toothbrush when brushing teeth. That is, the dentifrice is used integrally with the toothbrush, and not only the dentifrice. Therefore, toothpaste and toothbrush are always required for cleaning teeth, and even if only a small amount of toothpaste is used, the toothbrush and the container containing the toothpaste are carried, and in some cases it is not inconvenient. It was On the other hand, there was a solid toothpaste in which an abrasive was hardened with a binder mainly of soap, but this was also used with a toothbrush, and since soap is the main ingredient It is hardly used at present, because it has the drawbacks of being difficult to fix, fixing calcium salts, having an unpleasant odor, and having a limited fragrance for toothpaste. As described above, any toothpaste exhibits its function when used in combination with a toothbrush. However, in recent years, for beauty and health reasons, it has been desired to develop a dentifrice capable of easily cleaning teeth at any place.

(Problems to be Solved by the Present Invention) As described above, the conventional dentifrice exhibits its function when used in combination with the toothbrush, and the dentifrice is stored in the container and retains its form. . The present invention
When brushing teeth, a toothbrush is not required, and a container is not required for holding and holding the toothbrush. Therefore, it is an object of the present invention to provide a dentifrice which is convenient for handling and can clean teeth easily at any place.

(Means and Actions for Solving the Problems) In order to achieve the above object, a solid dentifrice that can achieve tooth cleaning simply by rubbing the dentifrice directly on the tooth surface without using a toothbrush and lightly gargle. The present invention provides. Since it is a solid type, it is easy to handle, stick type,
It can be processed into any shape such as pencil type, mechanical pencil type, etc., and it can also be processed into fiber or plate shape, so it is also possible to implant a processed toothpaste instead of the bristles of the toothbrush used conventionally. , Has a wide range of applications.
In general, dentifrices are abrasives for the purpose of removing plaque and coloring substances adhering to the surface of teeth, imparting wettability to the abrasives, preventing the scattering of the abrasives, and stabilizing the humectants on the surface of the dentifrice. It lowers the tension, enhances the cleaning effect on teeth and oral cavity, and contains a foaming agent for promoting dispersion and penetration, and a binder as an ingredient for preventing the separation of solid and liquid components. It is well known to include preservatives and medicinal ingredients. The solid dentifrice according to the present invention does not use a toothbrush, but rubs it onto the tooth surface and rinses it lightly to achieve tooth cleaning. It is necessary that the abrasive is uniformly dispersed in the solid dentifrice so as to cover the tooth surface and be applied to the tooth surface in a definite manner during rubbing. Abrasive used for this,
The type and amount of wetting agents and blowing agents and their dispersity play an important role. As the abrasive, wetting agent and foaming agent, it is possible to use the agents conventionally used in toothpaste, and it is preferable that the abrasive be as fine as possible, but generally the particle size used for toothpaste is sufficient. It is possible. Using hydroxyapatite as an abrasive
It can be said that it is particularly preferable because it has excellent adsorptivity for plaque and organic substances and has a property of easily adhering to the tooth surface and promoting remineralization. The ratio of the abrasive and the liquid component is important for the formation of the solid dentifrice, and if the ratio of the liquid component to the abrasive is too small, high pressure is required for molding, and the obtained solid dentifrice becomes brittle, It will be difficult to rub against the surface, and if it is too much, it will be difficult to maintain a solid form. Here, the liquid component means a wetting agent and water. A binder is added to the solid dentifrice of the present invention in relation to a liquid component as needed when the liquid component is large, and a binder conventionally used for a dentifrice is used. Other dentifrice ingredients such as effervescent agents, sweeteners, flavoring agents, preservatives and medicinal ingredients are added according to conventional dentifrices. That is, the solid dentifrice according to the present invention contains at least 95% by weight or less of an abrasive and 25% or less of a wetting agent; and 0.5 to 2.0% of a foaming agent, and contains a sweetener, a flavoring agent and a medicinal ingredient in the same manner as a conventional dentifrice. 0.1-1.0%, 0.6-2%,
And, if necessary, a small amount of water or a binder is added to the composition containing about 0 to 3%, and the mixture is sufficiently stirred with a kneader or other mixing stirrer to make it uniform, and then, with a roll or a speed line mill. Knead to disperse uniformly, defoam and then mold under pressure to obtain the desired form. The pressure during molding is selected according to the shape and hardness of the dentifrice, but generally 50 kg / cm ²
Moderate pressure is sufficient. The toothpaste thus obtained is evenly rubbed on the tooth surface and lightly gargleed to easily clean the teeth. The tooth surface can be rubbed with a dentifrice, but a toothbrush can be used.

 The present invention will be specifically described below with reference to examples.

The compositions having the following mixing ratios were uniformly mixed with a kneader, kneaded with a roll mill to be uniformly dispersed, defoamed under reduced pressure, placed in a mold and pressure-molded to obtain a solid dentifrice.

Use As a result, hydroxyapatite is adsorbed on the enamel demineralized part of the tooth surface and promotes its remineralization. In addition, abrasives, wetting agents, other components such as hydroxyapatite,
By using only food additives such as calcium carbonate, it is possible to obtain a dentifrice that does not require mouthwash after rubbing the dentifrice on the tooth surface.
