JPH032113A - Composition for oral cavity - Google Patents

Abstract

PURPOSE:To obtain a composition for oral cavity containing a zeolite on which a metal having antibacterial action is carried by ion exchange and capable of storing for a long period and exhibiting antibacterial action and action for preventing odor of mouth. CONSTITUTION:Metals of gold, silver and zinc having antibacterial action are subjected to ion exchange with A, X or Y type zeolite or mordenite using water soluble salt of these metals to carry the metals on the zeolite. The zeolite having the antibacterial action is blended and prepared to provide the aimed composition for oral cavity. Dentifrices are prepared by adding the above- mentioned antibacterial zeolite at an amount of 0.1-20wt.% and properly blending polishing agent, foaming agent, humectant, binder, sweetener, etc., therewith.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to oral compositions, and more particularly to oral compositions such as toothpastes and gingiva liniments having antibacterial properties.

[Prior Art] Oral compositions such as toothpastes contain preservatives to enable long-term storage, but such compositions generally contain abrasives, wetting agents, binders, and foaming agents. , foaming aids, and other various compounds are blended, and the types and blending ratios of these components must be combined in such a way that property changes such as component release and discoloration do not occur even after long-term storage. This also limits the types of preservatives that can be used.

It is also known to incorporate bactericidal or antibacterial medicinal ingredients into toothpaste compositions in order to prevent or alleviate various oral diseases caused by oral bacteria, but in this case, the same restrictions as above apply. In addition, sufficient consideration must be given to the side effects of medicinal ingredients.

[Object of the invention] The present invention aims to provide an oral composition that can be stored for a long period of time and exhibits an antibacterial effect in the oral cavity during use. The object of the present invention is to provide the above-mentioned oral cavity composition which is stable in a composition containing an inorganic abrasive such as an acid and an aluminum salt and is harmless to the human body.

[Structure of the Invention] The oral composition of the present invention is characterized in that it contains zeolite on which a metal having an antibacterial effect is supported by ion exchange.

Zeolite is a hydrous alkali metal salt or alkaline earth metal salt of crystalline aluminosilicate, and there are natural products and synthetic products, but in the zeolite used in the present invention, some or all of the metals are ion-exchanged with a metal that has antibacterial activity. It is something. Examples of zeolites suitable for the present invention include A-type zeolite, X-type zeolite, Y-type zeolite, mordenite, etc. Among these, zeolites with as large a specific surface area as possible are desirable.

As the antibacterial metal, one or more of copper, silver, and zinc can be used, but silver is most preferred.

In order to support these metals on zeolite, water-soluble salts of these metals may be used to perform ion exchange with the zeolite. The ion exchange method for these metals and the antibacterial action of zeolite supporting these metals are well known (for example, JP-A-61-138658, JP-A-63-15654).
0).

Typical applications of the present invention are dentifrices such as toothpastes, moisturizing toothpastes, and toothpastes, but it can also be applied to gingival liniments and other medicinal agents.

In the case of dentifrices, conventional dentifrice formulations such as abrasives, foaming agents, foaming aids, wetting agents, binders, sweeteners, etc. are suitably incorporated.

For example, abrasives include calcium carbonate, calcium diphosphate, calcium pyrophosphate, aluminum hydroxide, silicic anhydride, etc. Foaming agents include sodium lauryl sulfate, sodium N~ruacylsarcosine polyoxyethylene sorbitan, and foaming aids include sodium lauryl sulfate, sodium N-ruacylsarcosine polyoxyethylene sorbitan, Wetting agents include glycerin, propylene glycol, polyethylene glycol, sorbitol, etc. Binding agents include sodium carboxymethylcellulose, methylcellulose, sodium alginate,
Carrageenan and the like are used.

The blending amount of the antibacterial zeolite varies depending on the purpose of use, but when applied to toothpastes, it can be blended in a range of 0.1 to 20% by weight. The antibacterial effect can be adjusted by adjusting the amount of metal supported, and if it also functions as an abrasive, it can be used even above the upper limit of the above range.

[Function] Since the oral composition of the present invention contains zeolite that has an antibacterial effect, it can suppress spoilage caused by various bacteria and can be stored for a long period of time. At the same time, the adsorption effect of zeolite also prevents bad breath, and zeolite itself can also act as an abrasive. Especially in dentifrice compositions, zeolite is stable and does not precipitate other components or cause discoloration.
