Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the improvement of stable foamable molded products that do not undergo deterioration during storage.

Conventionally, tablets that generate bubbles when placed in water,
It is used in various fields such as medicine, industrial and household cleaning agents, and denture cleaning agents. These foaming agents include hydrogen peroxide adducts and chlorinated intheater acid. Pressure-molded product containing peroxysulfate, barium hydrogensulfate, etc.

Alternatively, products made by blending solid organic or inorganic acids with alkali metal carbonates, alkali metal bicarbonates, etc. are generally known, but in order to exhibit hygroscopicity,
When an ordinary packaging container 1 is stored sealed in a polyethylene bag, for example, it gradually absorbs moisture and decomposes, and in severe cases, the bag may be damaged by the gas generated by the decomposition. Furthermore, even if the product is stored in moisture-proof packaging to completely suppress moisture absorption, similar problems occur due to trace amounts of moisture in the raw materials and during JIJ processing.

However, although there have been some proposals intended to solve these problems, nothing has yet been achieved. for example,
In the method of suppressing hygroscopicity by adding powders such as tanoshi, zeolite, and silica, when the foaming agent is added to water.

The water is cloudy, again. As another example, a method is known in which the surface of a foaming agent component such as hydrogen peroxide addition compound monobicarbonate is coated with polyvinyl alcohol; When added to water, a sufficient foaming effect is often not obtained. Another example is a tablet in which a foaming agent component is molded into a laminated groove structure. The foaming effect is still not sufficient.

As a result of our research, the present inventors found that hypercarbonate (IJum).

Sodium perborate, etc. and dichloroisocyanuric acid)
Boron oxide B2O5 total [1
When the molded product is sealed and stored in an ordinary polyethylene bag, no decomposition gas is generated for an extremely long period of time, and it shows extremely good foaming properties even when placed in water. They completed the present invention by discovering that the components of the molded product were completely dissolved and the water did not become cloudy.

The purpose of the present invention is to: The object of the present invention is to provide a foamable molded product that does not undergo deterioration during long-term storage, exhibits extremely good foaming properties even when placed in water, and is completely soluble in water. The stable foamable molded product of the present invention contains hydrogen peroxide compound 100%
A powder formulation containing 4 to 500 parts by weight of chlorinated isocyanuric acid, peroxysulfate or peroxyhydrogensulfate, or 100 parts by weight of alkali metal carbonate or alkali metal bicarbonate and a solid organic acid or Inorganic acid 1
It is characterized in that 01 to 50 parts by weight of boron oxide is added to 100 parts by weight of a powdery compound containing 0 to 100 parts by weight, and the mixture is press-molded.

As the chlorinated incyanuric acid used in the present invention, c.
Examples include anhydrous sodium or potassium salts or hydrated salts of trichloroin cyanuric acid, dichloroin cyanuric acid, and dichloroisocyanuric acid. Preferred chlorinated isocyanuric acids include potassium dichloroisocyanurate, anhydrous salt of lium dichloroisocyanurate, and sodium dichloroisocyanurate dihydrate. The peroxysulfate or peroxyhydrogensulfate used in the present invention includes:

Examples include sodium peroxysulfate, potassium peroxysulfate, sodium peroxyhydrogensulfate, potassium peroxyhydrogensulfate, and the like. Examples of the alkali metal carbonate or alkali metal bicarbonate used in the present invention include 9.

Sodium carbonate, potassium carbonate, sodium bicarbonate Uno 2
．． Examples include potassium hydrogen carbonate. Examples of the solid organic or inorganic acids used in the present invention include citric acid, tartaric acid, adipic acid, malic acid, succinic acid, boric acid, sulfamic acid, and acidic phosphates. These hydrogen peroxide adducts, chlorinated isotheateric acid.

Peroxysulfate, peroxyhydrogensulfate.

Alkali metal carbonates, alkali metal bicarbonates.

Solid organic acids, solid inorganic acids, etc. are all available as commercially available industrial products, but powdered products with a moisture content of about 3% or less are particularly preferred.

In contrast to the above hydrogen peroxide addition compound, the above chlorinated isocyanuric acid. Peroxy sulfates, peroxy hydrogen sulfates, etc. act as oxidizing agents in water and cause the generation of oxygen gas through decomposition. In addition, the solid organic acid, inorganic acid, etc. for the alkali metal carbonate or alkali metal bicarbonate are neutralized in water.

It acts to generate carbon dioxide gas. The above hydrogen peroxide addition compound and chlorinated isotheateric acid. peroxysulfate,
Blends with peroxy hydrogen sulfate, etc., or blends of the above-mentioned alkali metal carbonates, alkali metal nail carbonates, etc. with solid organic acids, inorganic acids, etc., do not deteriorate during storage if they are in powder form. There are also problems with powder dust and measuring problems when using it, especially since it has poor dispersion in water.

These formulations may also be used as pressed granules, pills or tablets. However, even these pressure-molded foaming agents absorb moisture during storage as described above, and as the moisture is removed, decomposition gas is generated.After long-term storage, the properties deteriorate considerably and the desired foaming effect is not achieved. is not obtained.

The foaming agent of the present invention is a tablet, pill or granule obtained by further adding boron oxide B, 03 to the powdery foaming composition before the pressure molding. It is a drug. The boron oxide used in the present invention exhibits strong hygroscopicity in the foaming agent, and thus the trapped moisture acts to convert the boron oxide into boric acid without existing as free water.

The produced boric acid has no effect on the foaming agent's solubility in water and foaming properties, and prevents the foaming agent from deteriorating in quality.

It acts to preserve it stably. It has been found that in order to obtain a preferable pressure-molded foaming agent, it is necessary to limit the properties and composition of the blended components. 7 Jl with hydrogen peroxide + 100 parts by weight of the compound, chlorinated intheater acid.

100 parts by weight of alkali metal carbonate or alkali metal bicarbonate and 10 parts by weight or less of solid organic acid, inorganic acid, etc. or 1 part by weight or less.
00 parts by weight or more is not preferable because the dispersion and dissolution of the compound will be uneven. Furthermore, if the amount of boron oxide to be added is less than 0.1 parts by weight per 100 parts by weight of the powdery compound, the deterioration prevention effect becomes poor, and -1.

If the amount exceeds 50 parts, the concentration of the foaming active ingredient in the foaming agent decreases, and sufficient foaming properties cannot be imparted. Regarding the above composition, when using chlorinated isodoanuric acid,
In particular, when the overly targeted IJ is contained, it also exhibits sterilizing, bleaching, and other effects in water, and may be particularly advantageous.

As long as the purpose of the present invention is achieved, the foaming agent of the present invention may contain, in addition to the above-mentioned ingredients, optional ingredients such as colorants, fragrances, surfactants, fillers, etc. No problem. Usually, it is sufficient to add a small amount of coloring agent 1, fragrance 1, etc.

If a cleaning effect is to be imparted, surfactant gold may be added as necessary. In addition, as the extender, it is necessary to select an appropriate amount of components that are water-soluble, non-altering, and do not impair foaming properties. It is preferable that the above-mentioned powdery compound and a compound in which boron oxide is added are evenly mixed with VC. , v-type blender, etc. As mentioned above, a powdery formulation containing 100 parts by weight of a hydrogen peroxide compound and 4 to 500 parts by weight of a chlorinated isocyanuric acid, peroxysulfate or peroxyhydrogensulfate, or an alkali metal carbonate or 100 M parts of a powdered formulation containing 100 parts by weight of an alkali metal bicarbonate and 10 to 100 parts by weight of a solid organic or inorganic acid Vr - 01 to 30 parts by weight of boron oxide
