Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a foamable composition capable of uniformly dissolving an active ingredient while foaming in water and exhibiting effects such as bleaching, washing, deodorizing, and sterilization. The composition of the present invention is useful as a cleaning agent for pipes such as wastewater, a bleaching agent for kitchen cloths and cutting boards, a disinfectant and the like.

[0002]

2. Description of the Related Art As a method for uniformly dissolving a drug without physical action such as stirring, a method in which a water-soluble organic acid such as succinic acid or citric acid is mixed with sodium carbonate or sodium bicarbonate, and water is added thereto is used. Means for bubbling the carbon dioxide gas when it is brought into contact with is adopted. JP-A-7-1
No. 7841 discloses that potassium monopersulfate is used as an active oxygen generating substance as a denture cleaning agent. However, when this type of foam composition is mixed and packaged, in order to eliminate the influence of moisture, the humidity of the working environment should be extremely reduced, or for packaged products, pinholes should be provided in the packaging film to generate gas to the outside. Measures such as leaking have been taken.

[0003]

SUMMARY OF THE INVENTION The present invention relates to the preparation of a foaming composition capable of exerting effects such as bleaching, washing, deodorizing, and disinfecting by supplying active oxygen into water, and controlling the working environment. Alternatively, an object of the present invention is to provide a foamable composition which does not require treatment of a packaging material and has excellent storage stability.

[0004]

The present inventors have conducted various tests in order to achieve the above object, and as a result, as alkali metal carbonates, sodium carbonate, sodium bicarbonate and sodium percarbonate (chemical formula: 2Na ₂ CO ₃・ 3H ₂
O ₂ ), and a double salt compound of potassium peroxymonosulfate / potassium hydrogen sulfate / potassium sulfate (chemical formula: 2KHSO ₅
KHSO ₄ .K ₂ SO ₄ (hereinafter referred to as an oxone monopersulfate compound) and anhydrous magnesium sulfate were blended to find that it had excellent storage stability and good foaming properties in water. The invention has been completed.

The oxone monopersulfate compound has a pH of 2.3 in a 1% by weight aqueous solution, and acts on an alkali metal carbonate to generate carbon dioxide gas, and at the same time, an active oxygen which exhibits bleaching and sterilization. The anhydrous magnesium sulfate has the effect of taking in the water in the mixed system as stable crystallization water and stabilizing the mixture.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Alkali metal carbonate reacts with an acidic agent to generate carbon dioxide gas, and is generally known to include sodium carbonate, sodium bicarbonate and sodium percarbonate. On the other hand, the present invention uses an oxone monopersulfate compound which releases active oxygen and has functions of bleaching and disinfection as an acid agent for an alkali metal carbonate. The amount of the oxone monopersulfate compound used in the practice of the present invention should be in the range of 10 to 90% by weight, preferably 30 to 70% by weight, based on the foamable composition. If the amount used is less than 10% by weight, the active oxygen concentration at the time of use is too low to obtain a satisfactory effect. If the amount used exceeds 90% by weight, the content of alkali metal carbonate is reduced. The proportion decreases, and the foamability is significantly reduced. The oxone monopersulfate compound as an acidic agent may be used in combination with conventionally used organic acids such as citric acid, succinic acid, and fumaric acid.

[0007] The amount of anhydrous magnesium sulfate used in the present invention is selected from the group consisting of foaming composition, since the purpose is to fix water brought in as raw materials or a trace amount of water mixed during mixing, packaging and the like as crystal water. 0.5 to 1
It should be used in the range of 0% by weight, preferably 2-5% by weight. Another feature of the composition of the present invention is that it is composed entirely of relatively soluble water-soluble components and does not leave any insoluble matter when used. The composition of the present invention may contain a surfactant, a fragrance and a pigment according to the purpose of use. The shape of the effervescent composition is not particularly limited, and may be either granular or tablets obtained by dry compression.

EXAMPLES Hereinafter, the present invention will be described specifically with reference to Examples and Comparative Examples, but the present invention is not limited to these. The raw materials used in Examples and Comparative Examples are as follows.・ Sodium carbonate (manufactured by Tokuyama) ・ Sodium bicarbonate (manufactured by Tokuyama) ・ Sodium percarbonate (manufactured by Nippon Peroxide) ・ Oxone monopersulfate (trade name: Oxone, manufactured by Dupont) ・ Anhydrous magnesium sulfate (Japanese) Kojun Pharmaceutical Co., Ltd.]-Citric acid [Fuso Chemical Co., Ltd.]-Succinic acid [Takeda Pharmaceutical Co., Ltd.]

Example 1 10 parts by weight of sodium carbonate,
10 parts by weight of sodium percarbonate, 75 parts by weight of an oxone monopersulfate compound and 5 parts by weight of anhydrous magnesium sulfate were uniformly mixed to obtain a 1% by weight aqueous solution having a pH of 8.0 as a particulate mixture. A 30 g sample was collected from the mixture, one of which was placed in an aluminum foil laminated film as it was and sealed by heat sealing, and the other was 37 m in diameter.
A tablet having a thickness of 18 mm was obtained by compressing with a surface pressure of 1.0 t / cm ² using a mortar and pestle, and placed in an aluminum foil laminated film in the same manner as described above, and sealed by heat sealing.

In order to carry out an accelerated evaluation test on these samples, the samples were kept in a thermostat at a temperature of 40 ° C. and a humidity of 75% for 30 days, and the state of the packaging material and the foaming property when the sample in the packaging material was put into water Was examined over time. Table 1 shows the results of these tests.
As shown in the above, all the samples did not have swelling of the film, and there was no difference in the foaming property from that immediately after mixing.

[Examples 2 to 4] Samples were prepared in the same manner as in Example 1 according to the composition shown in Table 1,
An acceleration evaluation test was performed under the same conditions as in Example 1. The results of these tests are as described in Table 1. In each sample, there was no swelling of the film, and there was no difference in the foaming property from that immediately after mixing.

[Comparative Examples 1 to 4] Samples were prepared in the same manner as in Example 1 according to the composition shown in Table 2,
An acceleration evaluation test was performed under the same conditions as in Example 1. These test results are as described in Table 2. Since anhydrous magnesium sulfate was not blended, the foaming composition could not be stabilized. Rupture occurred, and the foamability was weaker than that immediately after mixing, and many undissolved portions were observed.
