Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention is excellent in detergency for ordinary light stains such as food residues and denture plaque and stubborn stains such as stains and tartar, and is used for washing and sterilizing ordinary light stains. The present invention relates to a denture cleaning agent having a color timer function by which the end of the cleaning can be visually confirmed.

2. Description of the Related Art Denture stains include mild stains such as food residues and denture plaques, protein and calcium salts deposits in saliva, and pigments in foods and drinks such as coffee and tea. There are stubborn stains such as deposits, stains on cigarettes and tartar. These deposits and deposits may cause not only bad breath but also denture stomatitis. For this reason, dentures must be frequently cleaned and kept clean.

[0003] However, at present, when a denture user cleans a denture, it is sensible to clean it. Therefore, when it is sufficient to remove a light dirt, the dirt cannot be completely cleaned. The washing operation may be terminated or, on the contrary, excessive washing may be performed. Therefore, a denture cleaning agent that can quickly and efficiently wash light stains and that can change the color of the cleaning liquid to visually confirm the end of cleaning is desired. It is also convenient for stubborn dirt if the end of cleaning can be visually confirmed.

[0004] It has been known to impart a color timer function to a cleaning agent, and for example, Japanese Patent Publication No. 62-4 / 1987.
1644 and JP-A-1-125316. However, both proposals disclose the second dye from the first dye.
The discoloration time to the dye is long, and its function is insufficient to confirm the end of washing of ordinary dirt and use it as a guide to end washing in a short time.

The present invention has been made in view of the above circumstances, and has excellent denture dirt cleaning power for both light dirt and stubborn dirt, and is visually observed at the end of light dirt cleaning and sterilization. It is an object of the present invention to provide a denture cleaning agent having a color timer function which can be confirmed by confirmation.

Means for Solving the Problems and Embodiments of the Invention The present inventors have conducted intensive studies in order to achieve the above object, and as a result, have found that potassium hydrogen persulfate (1) is used as an oxygen-based bleaching component (soil removing component). 30% by weight and sodium perborate 10
~ 80 wt% and sodium tripolyphosphate in 1 ~ 30
In the denture cleaner mixed with the weight%, 0.01 to 0.1% by weight of blue No. 1 as the first pigment of the color timer component and 0.03 to 0.15% by weight of green 401 as the second pigment
Or 0.02 to 0.08% by weight of Blue No. 1 as the first dye and 0.004 to 0.016% by weight of Red No. 3 as the second dye, When this denture cleaning agent is used by dissolving it in water, the denture cleaning agent exhibits excellent denture detergency and removes ordinary light stains such as food residues and denture plaque in a relatively short time (usually 3 to 10). ), But this denture cleaning solution is initially colored blue by the addition of the first and second dyes, and is usually 3 to 3 so that it can correspond to the light stain removal. The change from blue to green or red in about 10 minutes, that is, the time when the blue based on the first dye disappears and changes to the color based on the second dye almost coincides with the light stain removal time for the denture, and The end of the light stain removal is It has been found that when the purpose is to wash and remove ordinary light stains such as food residues and denture plaque, the washing can be terminated based on the color change. . When green No. 401 is used as the second dye,
After changing from blue to green, the green color continues, and the green color (second color) continues even after 2 hours when stubborn stains such as stains and tartar are finished, preventing misunderstanding as water. On the other hand, when Red No. 2 is used as the second pigment, the color changes from the second color to colorless two hours after washing of stubborn stains such as stains and tartar is completed, and has a double color timer function. This led to the present invention.

Accordingly, the present invention provides (1) 1 to 30% by weight of potassium hydrogen persulfate, 10 to 80% by weight of sodium perborate and 1 to 30% by weight of sodium tripolyphosphate as oxygen-based bleaching components. A denture cleaner comprising 0.01 to 0.1% by weight of Blue No. 1 as one dye and 0.03 to 0.15% by weight of Green No. 401 as a second dye, and ( 2) 1 to 30% by weight of potassium hydrogen persulfate, 10 to 80% by weight of sodium perborate, 1 to 30% by weight of sodium tripolyphosphate as an oxygen bleaching component, and 0.02 of Blue No. 1 as a first pigment
-0.08% by weight, 0.003 of red No. 3 as the second dye
The present invention provides a denture cleanser characterized by containing 4 to 0.016% by weight.

Hereinafter, the present invention will be described in more detail. The denture cleaner of the present invention comprises potassium hydrogen hydrogen persulfate (component A) and sodium perborate (component B) as oxygen-based bleaching components, and sodium tripolyphosphate. It contains.

Here, the amount of potassium hydrogen hydrogen persulfate is 1 to 30% by weight, preferably 1 to 19% by weight of the whole detergent.
% By weight. When the amount is less than 1% by weight, the foaming property when administered to water is weak, and the preparation does not dissolve uniformly, so that the desired detergency cannot be obtained. There is a risk of occurrence.

The amount of sodium perborate is from 10 to 80% by weight, preferably from 31 to 80% by weight, based on the whole detergent. If the amount is less than 10% by weight, the amount of active oxygen is small and sufficient detergency cannot be obtained. If the amount exceeds 80% by weight, the cleaning effect reaches saturation, so that further addition becomes meaningless.

In the cleaning agent of the present invention, the two types of oxygen bleaching agents may be mixed in such a manner that the component B is more than the component A in terms of preventing blackening of denture metal and preserving the storage stability. Preferably, the mixing ratio of component A / component B is 1/1 to 1/10 by weight, particularly 1/1 to 1 in consideration of detergency.
/ 6 is desirable. If it exceeds 1/1, the metal of the partial denture may be changed.
If it is less than the above, the detergency decreases.

Further, potassium hydrogen persulfate (component A)
And the amount of sodium perborate (component B) is A + B = 5
The content is preferably 0% by weight or more, particularly preferably 55 to 65% by weight, and if it is less than 50% by weight, a desired detergency cannot be obtained.

It is possible to mix sodium percarbonate instead of the above-mentioned component B of sodium perborate, or to replace a part of sodium perborate with sodium percarbonate. It does not impair the cleaning effect.

Next, sodium tripolyphosphate is compounded to prevent discoloration of the metal, and its compounding amount is 1 to 30% by weight, preferably 10 to 20% by weight.
If the amount of sodium tripolyphosphate is less than 1% by weight, the effect of preventing discoloration of the metal cannot be obtained, and if it exceeds 30% by weight, saturation is reached, so that further addition is meaningless.

The denture cleaner of the present invention may contain other optional components in addition to the above essential components. Specifically, as an optional component, an alkalizing agent, a neutralizing agent, a disintegration accelerator, a surfactant such as sodium lauryl sulfate,
Sulphate anion activators such as sodium EO addition alkyl ether sulfate, sodium dodecylbenzenesulfonate, sodium α-oleylsulfonate, N
-Anionic surfactants such as sulfonic acid surfactants such as sodium lauroylmethyltaurine, carboxylic acid surfactants such as sodium lauroyl sarcosine, phosphate surfactants such as EO-added alkyl ether sodium phosphate, and EO addition Nonionic surfactants such as alkyl ether nonionic surfactants such as alkyl ethers, alkyl phenyl ethers such as EO-added nonylphenyl ether, and dialkyl ether nonionic surfactants can be exemplified. The addition amount of the surfactant is preferably 0.05 to 10% by weight based on the entire cleaning agent.

In addition, sodium percarbonate, sodium persulfate, sodium peroxide, etc. other than the above-mentioned oxygen bleaching agent, which is an essential component of the present invention, may be blended as long as the effects of the present invention are not impaired.

Further, an organic acid such as citric acid or sulfamic acid is blended as a foaming component in the denture cleaning agent.
The cleaning agent of the present invention contains excess B in peroxide as a bleaching component.
Combination of component (alkaline) and a small amount of component A (acid) when dissolved in water (1% by weight aqueous solution of detergent)
By adjusting the pH to 8-11, it is possible to spread rich and fine oxygen bubbles (oxygen generated by the decomposition of sodium perborate) into the cleaning solution. May not be included.

It is preferable to add an enzyme as an optional component. Examples of the enzyme include alkaline protease, dextranase, β-1,3-glucanase, mutanase, amylase and the like. The addition amount of the above enzyme is preferably in the range of 0.05 to 10% by weight of the whole.

As optional components, for example, binders such as polyvinylpyrrolidone, lactose, and Avicel, and various flavors can also be blended. In addition, the addition amount of these optional components can be a usual amount as long as the effects of the present invention are not impaired.

Thus, the denture cleanser of the present invention contains Blue No. 1 as the first pigment and Green 401 or Red No. 3 as the second pigment.

Here, the compounding amount of blue No. 1 is 0.0% of the total amount of the cleaning agent when green No. 401 is used as the second dye.
1 to 0.1% by weight, preferably 0.015 to 0.05% by weight. When Red No. 3 is used as the second dye,
0.02-0.08% by weight, preferably 0.03-0.08% by weight.
05% by weight. If the amount is too small, the coloring property when administered to water is weak, and it is difficult to recognize the liquid color of the detergent. If the amount is too large, it is difficult to recognize the color change to the second dye. The compounding amount of the green color No. 401 of the second dye is 0.03 to 0.15% by weight,
It is preferably 0.03 to 0.1% by weight, and the blending amount of Red No. 3 is 0.004 to 0.016% by weight, preferably 0.0045 to 0.008% by weight. If the amount of the second pigment is too small, the discoloration from blue is difficult to recognize, and if it is too large, the initial liquid color does not become blue. In this case, the ratio of blue No. 1 and green No. 401 is 1/1 to 1 by weight.
1/3, and the ratio of Blue No. 1 to Red No. 3 is 3 /
From 1 to 10/1 is preferred from the viewpoint of liquid color and color change.

The denture cleanser of the present invention can be prepared as a liquid or, if necessary, prepared in the form of powder, granules or tablets, and dissolved in a solvent such as water or hot water before use. It may be in the form of, but usually 1-5 of denture cleanser
g is dissolved in 100-300 ml of water and used, the normal coloring of food residue and denture plaque and the like is changed from the first pigment to the second pigment in 3 to 10 minutes after washing is completed.
When green 401 is used as the second pigment after 2 hours from the end of the cleaning of the stubborn stains such as stains and tartar, the green color continues and the cleaning solution is colored. Can be prevented. On the other hand, when Red No. 3 is used as the second dye, the red color disappears and becomes colorless after 2 hours, and it is possible to recognize the end of stubborn dirt washing.

In this case, the denture cleansing agent of the present invention has a pH value of 8 to 11, especially 8 when dissolved in water (pH value of a 1% by weight aqueous solution) in consideration of cleaning performance and harmfulness to the skin. It is preferable to adjust so as to be 5 to 10.5. If the pH value at the time of dissolving in water is less than 8, sufficient detergency may not be obtained, and if the pH value exceeds 11, the safety of hands and fingers due to alkali may become a problem.

The pH adjustment of the above denture cleaner is preferably carried out by adding a pH adjusting acid such as an inorganic phosphate such as disodium dihydrogen pyrophosphate and monosodium dihydrogen phosphate in terms of storage stability. . In addition, when an organic acid such as citric acid and sulfamic acid or a pH adjusting acid agent such as a salt thereof, which is generally used for a denture cleaning agent, is used, moisture absorption and solidification may be induced.
