Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a denture cleaning foam composition used for cleaning and sterilizing dentures.

[0002]

2. Description of the Related Art It is known that dentures are often contaminated not only with food residues and coloring matters, but also with microbes derived from oral microbes during wearing. In particular, denture plaque often adheres to the denture base mucosal surface.

[0003] In order to remove these stains, conventionally, as a denture cleaning agent, an oxygen-based material such as sodium peroxide, sodium perborate, sodium persulfate, potassium hydrogen persulfate (OXONE manufactured by DuPont) has been used. Bleaching agents; chlorine bleaching agents such as sodium hypochlorite, sodium dichlorisocyanurate, sodium trichloroisocyanurate; enzymes such as alkaline protease, dextranase, mutanase, inulase, glucanase, lipase, papain; and acids And a composition containing an active ingredient such as alkali and the like.

[0004] In addition, various relatively inactive ingredients such as lubricants such as magnesium stearate and silicon dioxide, extenders, binders, coloring agents, dyes, and mint oil are added to a composition containing these active ingredients. By appropriately adding a fragrance such as l-menthol or the like, a denture cleaning agent having a desired size and density or color and flavor has been obtained.

[0005] Further, in order to obtain a foaming detergent for enhancing the physical cleaning effect, a carbon dioxide-generating mixture comprising a carbonate compound and an acid is further added to the composition containing the above-mentioned active ingredient. I was Known carbonate compounds are alkali metal carbonates or bicarbonates, for example sodium, potassium, lithium or rubidium carbonates or bicarbonates. On the other hand, the acid component is generally citric acid, tartaric acid, succinic acid, fumaric acid, or a mixture thereof, but may be another acid containing sodium or potassium acid phosphate, or a mixture thereof. It has been known.

[0006] The dirt adhering to the denture and the denture base is bleached, disinfected, sterilized by the combined action of the active ingredient of the denture cleaner, the physical action of the foaming agent, and the surface tension reducing function of the surfactant. It is possible to wash with effects such as protein decomposition and carbohydrate decomposition.

[0007]

However, it has been difficult to shorten the disintegration time of the tablet and to perform the washing in a short time with this foaming detergent.

It is an object of the present invention to provide a foaming composition for denture cleaning in which the disintegration time of the tablet is reduced and the cleaning effect is not reduced even if the cleaning time is short.

Incidentally, silicon dioxide used in the denture cleaning foam composition of the present invention has been conventionally added as a lubricant when added to a denture cleaning agent (regardless of the foaming detergent).
However, the present inventors have found that the disintegration time can be controlled by the content of silicon dioxide, and have reached the present invention.

[0010]

Means for Solving the Problems The denture cleaning foam composition of the present invention is characterized by containing silicon dioxide.

[0011] In the foaming composition for denture cleaning of the present invention,
The silicon dioxide is preferably contained in an amount of 0.1% by weight to 1.0% by weight.

[0012]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in more detail.

The silicon dioxide used in the present invention is preferably incorporated in the foaming composition for denture cleaning in an amount of 0.1% by weight to 1.0% by weight.
In order that the washing effect is not reduced even if the washing time is short, 0.25% by weight to 0.50% by weight can be preferably added. If the amount is less than 0.1% by weight, the disintegration time is long, and it takes time to wash. Conversely, if the compounding amount exceeds 1.0% by weight, there is a problem that tablet molding becomes difficult.

In order to obtain the foaming detergent for denture cleaning of the present invention, a foaming component which is a carbon dioxide-generating mixture comprising a carbonate compound and an acid is contained.

As the carbonate compound, an alkali metal carbonate or bicarbonate such as sodium, potassium, lithium, or rubidium carbonate or bicarbonate can be used.

On the other hand, citric acid, tartaric acid,
Succinic acid, fumaric acid, or mixtures thereof are common, but other acids, including sodium or potassium acid phosphate, or mixtures thereof can be used.

The foaming composition for denture cleaning of the present invention further comprises sodium peroxide, sodium perborate, sodium persulfate and potassium monohydrogensulfate (OXON (OXON manufactured by DuPont)) as active ingredients as cleaning agents.
E) Oxygen bleach such as); sodium hypochlorite,
Chlorine bleaching agents such as sodium dichlorisocyanurate and sodium trichlorisocyanurate; enzymes such as alkaline protease, dextranase, mutanase, inulase, glucanase, lipase, papain;
Active ingredients such as acids and alkalis can be appropriately blended.

The composition containing these active ingredients may be added to various relatively inactive ingredients such as lubricants except for magnesium stearate, extenders, binders, coloring agents, dyes, mint oil, l-menthol and the like. And the like can be appropriately added in order to obtain an arbitrary dosage form such as, for example, granules, granules, and tablets.
