Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a foamy oral composition, which is filled with a liquid oral composition in a non-aerosol type non-gas container and ejected and applied in a foamy state at the time of use, particularly during use. Relates to a foamy oral composition having good foam uniformity, good shape retention of foam in the oral cavity during use, and good feeling in use, and high dispersibility in the oral cavity.

[0002]

BACKGROUND OF THE INVENTION Oral compositions such as dentifrices are used for cleaning the inside of the oral cavity and, in the case of containing a medicinal component, to exert the effect of the medicinal component. It is important that the oral composition is easily spread to every corner of the oral cavity, and therefore a formulation having high dispersibility is desired.

Oral compositions are usually prepared in the form of liquids, pastes, etc. Among them, liquid dentifrices are known as highly dispersible preparations. However, the conventional liquid dentifrice has a problem in usability because it brushes the liquid while it is still contained in the mouth or after it has been exhaled. There is no lubricity at the time of brushing, and the usability is not good.

On the other hand, a toothpaste has a poor dispersibility as compared with a liquid dosage form because the preparation is dispersed in the oral cavity by mixing saliva and the preparation by brushing, and foaming becomes strong over time. There are also problems such as difficulty in brushing for a long time.

From these points, some techniques have been proposed in which a liquid dentifrice is blended with a foaming agent and foamed at the time of use to brush in a foamy form. For example, a method of encapsulating a formulation system containing a surfactant, water, a viscous agent, etc. in a pressure resistant container together with carbon dioxide gas, air, etc. to form a mousse-like foam (JP-A-63-233908) or There is known a method (Japanese Patent Laid-Open No. 3-77814) in which an inert gas and a mouthwash are pressurized and filled in a pressure-proof light-shielding container, and mousse-like bubbles are ejected during use.

However, most of the liquid dentifrice to be used in the form of foam is an aerosol type which is enclosed in a pressure resistant container as described above, and there is a problem in safety and environment in use and disposal. In addition, when prepared in a non-aerosol type, the foam when placed on the brush may be uneven depending on the composition, or the foam may become weak during use, resulting in uniform foam, shape retention and feeling of use. Was inferior to

The toothpaste and aerosol dentifrices are mainly used for physical cleaning with an abrasive, but may not be suitable for use when there is root surface exposure or periodontal disease.

Further, conventionally, there is a gel type coating agent using a dental tray, but this formulation has a high viscosity and the activity and dispersibility of the active ingredient are poorer than those of the liquid agent and the like. In addition, since the amount required to fill the tray is necessary for application, it is necessary to use an amount more than the required amount of the formulation, which is problematic in terms of safety and economy.

The present invention has been made in view of the above circumstances, and it is filled in a non-gas type atmospheric pressure container and can be applied by brushing in a foam state at the time of use. Uniformity of foam, shape retention of foam in the oral cavity. It is an object of the present invention to provide a foamy oral composition which does not contain an abrasive and which has a good feeling in use and excellent dispersibility in the oral cavity.

In this case, the polymer compound of group A and the polymer compound of group B have a high viscosity. The mixing ratio with the molecular compound is B / A =
0.2 to 200, and A for the entire liquid oral composition
By blending in the range of + B = 0.06 to 2% by weight, a uniform and good foam is obtained when the non-gas container is filled and used, and it is a foam at the time of use. In addition, the shape retention of bubbles when actually placed on a jig such as a brush or a dental tray is good, and there is little stickiness and stickiness of bubbles during use, so brushing for a long time is possible and dispersibility is also In addition to being good, there is little stickiness, it has an excellent feeling of use, and there is no residual feeling by light rinsing after use, and the compounded drug easily stays,
