Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a treatment agent for toilet water, and more particularly to a treatment agent suitable for treating toilet water of a circulation type or a suction type, which has excellent bactericidal power, deodorizing property and durability. The present invention relates to a treatment agent for toilet water, which has a concealing power and is not contaminated by dyeing on textiles and the like.

[0002]

[Background of the Invention] Circulating toilets and suction toilets are used in aircrafts, railway vehicles, ships, long-distance buses, and the like. Circulating toilets have an appropriate amount of water previously put in a waste tank, and a treatment agent for toilet water is dissolved in this, and wash water is circulated by a circulation pump each time it is used.
This is a method of cleaning a toilet bowl (generally called a ball). Therefore, since the excrement is mixed with the wash water after the second use, the treatment agent for circulating toilet water is
Cleaning power, coloring power (hiding power), deodorant power, sterilization power, etc. are required.

The suction type toilet is a system in which the centralized waste tank is depressurized and the waste is collected from each toilet by suction. Since the ball is washed with fresh water (not reused) every time it is used, the treating agent is particularly used. It does not require coloring power and deodorizing power, but it is desirable to have these abilities so that the end-use contractor does not feel uncomfortable during work.

The conventional toilet water treatment agent contains a defoaming agent, an anticorrosive agent and the like in addition to a cleaning agent (surfactant), a bactericidal agent, a coloring agent and a deodorant. As the above-mentioned detergent (surfactant), a nonionic surfactant, an anionic surfactant, etc., and as a bactericidal agent, a salt of chlorinated phenol, a chlorinated bactericidal agent such as chlorinated cyanuric acid, 2-bromo-2- A bromine-based bactericide such as nitropropanediol-1,3 and a cationic bactericide such as benzalkonium chloride and octadecyltrimethylammonium chloride are used as deodorants for masking offensive odor components such as ammonia and hydrogen sulfide. Is used.

As the colorant, water-soluble dyes such as direct dyes, acid dyes, basic dyes and reactive dyes, water-insoluble dyes such as disperse dyes and oil-soluble dyes, pigments and the like are used. Pigments have various problems such as dyeing on fibers, stability, compatibility with germicides, and are not satisfactory.

Further, when a chlorine-based disinfectant is used, not only is the pungent odor peculiar to chlorine unpleasant on the nose, but there is also the problem of strong metal corrosion. Since the bromine-based bactericide has strong metal corrosion and weak bactericidal power, it is only used in a small amount to assist the cationic bactericide. For these reasons, conventionally, a cationic bactericide has been mainly used as the bactericide.

In addition, when a water-soluble dye is used as a coloring agent, there is a problem that if the dye adheres to clothes or other textiles, it will not fall off even after washing. Therefore, the treating agent as well as the treating agent was dissolved. Water handling requires caution. When a cationic bactericide is used as the bactericide, an anionic dye or a dye containing an anionic auxiliary agent reacts with the bactericide, and hiding power or bactericidal power is decreased. I have a problem. On the other hand, cationic basic dyes do not react with cationic bactericides, so there is no problem of reducing the bactericidal effect or hiding power, but since they are water-soluble dyes, the problem of dyeing to textile products There is.

On the other hand, water-insoluble dyes and pigments, although not dyed to fibers at room temperature, do not dissolve in water and do not disperse uniformly in water, so that they precipitate over time and have sufficient hiding power. There is a problem that the effect cannot be obtained. To disperse a water-insoluble dye or pigment in an aqueous system,
There are some that are dispersed with a surfactant to disperse in water for a long time, but the surfactant used for this is usually an anionic surfactant, so it is used as a disinfectant for toilet treatment agents. Reacts with cationic bactericides that are mainly used, causing aggregation of water-insoluble dyes or pigments,
Also, it cannot be used because it causes deterioration of sterilizing power.

[0009]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a toilet water treatment agent which has the excellent bactericidal power, concealing power, and deodorant power of conventional toilet water treatment agents, and in particular, which does not stain fibers. To do.

[0010]

SUMMARY OF THE INVENTION The inventors of the present invention have conducted various studies in order to solve the above-mentioned dyeing on fibers, reduction in bactericidal power, and inconvenience of handling dyes and pigments, and to achieve the above object. It is extremely preferable to use a colorant dispersion composed of a pigment or a water-insoluble dye dispersed with a nonionic, cationic, or amphoteric surfactant for a toilet treatment agent containing a cationic bactericide. We have found that it is effective.

Based on this finding, the present inventors have made further studies, and as a result, even if a cationic bactericide is used as a bactericide, if the above colorant dispersion is used, a) the above colorant Even if it adheres to the fiber, the color is easily removed by washing, b) no aggregation of the colorant and surfactant with the cationic bactericide, and the bactericidal action of this bactericide The present invention has been developed, and it has been found that c) does not disappear, and c) the hiding power can be maintained for a long period of time because a colorant dispersed with a surfactant is used.

[0012] That is, the present invention is a treatment agent for toilet water containing a cationic bactericide as a sterilizer, which is dispersed with at least one of a nonionic surfactant, a cationic surfactant and an amphoteric surfactant. Another feature of the present invention is a water treatment agent for toilet, which comprises a colorant dispersion containing at least one of a pigment, a disperse dye, and an oil-soluble dye.

The colorant in the colored dispersion of the present invention is
It has excellent concealing power for various substances (mainly human excrement) existing in toilet water, but it has low or no dyeing power to textiles such as clothes at room temperature, or even if it adheres, it can be washed with water. Those which can be easily washed off by washing with an ordinary detergent or are preferred, and specific examples thereof include pigments, disperse dyes and oil-soluble dyes.

Any of the above pigments, disperse dyes and oil-soluble dyes may be used alone, or two or more kinds may be used in combination.

Since these colorants are insoluble in water, they are dispersed with one or more surfactants selected from nonionic surfactants, cationic surfactants and amphoteric surfactants.

Examples of the nonionic surfactant include alkyl polyoxyethylene ether, alkyl polyoxyethylene / polyoxypropylene ether, fatty acid polyoxyethylene ester, fatty acid polyoxyethylene sorbitan ester, fatty acid polyoxyethylene sorbitol ester and polyoxy. Ethylene castor oil, alkyl polyoxyethylene amine, alkyl polyoxyethylene amide, fatty acid sorbitan ester, fatty acid polyglycerin ester, fatty acid sucrose ester, etc., as the cationic surfactant, primary amine salt, acylaminoethyldiethylamine salt, Alkyl trimethyl ammonium salts, alkyl polyoxyethylene amines and the like are used as amphoteric surfactants such as polyoxyethylene alkyl ether and polyoxyethylene. Down alkyl aryl ether, sorbitan mono-alkylate, sorbitan distearate alkylate,
Examples thereof include sorbitrial chelate and oxyethylene oxypropylene block polymer. Any of these surfactants may be used alone, or two or more kinds thereof may be used in combination.

The amount of the above-mentioned surfactant is not particularly limited as long as it can disperse the above-mentioned coloring agent, but it is generally 1 to 100% by weight with respect to the coloring agent, and if it is more than this, toilet water is used. Of the treatment agent of
Other necessary components in the treatment agent for toilet water do not enter, and when the amount is small, a good dispersion state cannot be maintained.

The method of dispersing the above-mentioned colorant using the above-mentioned surfactant may be any method as long as it can uniformly disperse the colorant in the dispersion medium. For example, the surfactant, the colorant and water. In addition to the above, it is possible to use a method of dispersing and mixing with a three-roll mill, a ball mill, a sand mill, an attritor, a paint shaker, etc. while appropriately containing an antifoaming agent, a preservative, a drying inhibitor, etc. .

As described above, the colorant dispersion of the present invention comprises a pigment, a disperse dye, and a pigment dispersed with at least one of a nonionic surfactant, a cationic surfactant and an amphoteric surfactant.
This colored dispersion comprising one or more oil-soluble dyes can be used as long as it can be uniformly dispersed in the treatment agent for toilet water according to the present invention. It is preferable to use fine particles having a dispersed state of 5 μm or less in average particle diameter. When a colorant dispersion in which the average particle size in this dispersed state is larger than 5 μm is used, the colorant in the dispersion can be treated with a surfactant for a long time even if it is treated with a surfactant. As a result, it becomes difficult to maintain a good dispersed state, and there is a concern that precipitation may occur when used in an aircraft that requires a long flight, for example. It should be noted that any method may be used to obtain a colorant dispersion in the form of fine particles having an average particle size of 5 μm or less in such a dispersed state. It can be obtained by, for example, a method of dispersing and mixing with the above-mentioned mill or the like in the wet state after the reaction product filtration and once dried, together with the above-mentioned surfactant, water and the like.

You may use it as a shape. When it is used as a liquid product, it can be stored for a long period of time if the water content is adjusted and the concentration is stable. When dried and used as a powder, a technique such as spray drying can be adopted.

In the above colorant dispersion, the amount of the colorant comprising at least one kind of pigment, disperse dye and oil-soluble dye in the dispersion is 0.1 based on the total amount of the toilet water treating agent of the present invention.
It is preferable to mix it in an amount of ˜25% by weight. When it is less than this range, the hiding effect of the colorant is deteriorated, and when it is more than this range, this hiding effect is saturated and it becomes uneconomical.

The cationic bactericide compounded in the treatment agent for toilet water of the present invention together with the above colorant dispersion is a quaternary ammonium salt compound, specifically, benzalkonium chloride and didecyldimethyl. Ammonium chloride, octadecyl trimethyl ammonium chloride, alkyl (beef tallow) trimethyl ammonium chloride, dodecyl trimethyl ammonium chloride, alkyl (palm) trimethyl ammonium chloride, hexadecyl trimethyl ammonium chloride, alkyl (palm) alkyl benzyl ammonium chloride, tetradecyl dimethyl benzyl ammonium chloride ,
