Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a solid detergent which is used by being poured into a water tank of a flush toilet, and which has a stable dye dissolution degree.

[0002]

2. Description of the Related Art A conventional solid detergent for flush toilets contains a dye as a colorant which is eluted at the same time as a surfactant as a washing component in order to clearly know the validity period of the detergent. ing.

[0003]

However, the conventional solid detergent for flush toilets has a very large dye dissolution rate in the initial stage of being used after being charged into the flush toilet water tank. Is colored more than necessary,
There is a problem that the dye is eluted to a degree that causes bad feeling.

[0004] The invention of this application has been made to solve the above-mentioned problems of the conventional solid detergent for flush toilets.

[0005]

SUMMARY OF THE INVENTION Therefore, the invention of this application relates to a solid detergent for flush toilets containing a surfactant and a dye as active ingredients, wherein the dye is represented by the following chemical formula: A solid detergent for flush toilets is a mixture of a fast-dissolving dye and a slow-dissolving dye represented by the following chemical formula:

In the invention of the present application, examples of the surfactant include polyoxyethylene polyoxypropylene block polymer, polyoxyethylene fatty acid diester, polyethylene glycol, and the like. About 30% by weight or more, but about 5% in terms of shape retention as a solid detergent.
A range of 0 to 90% by weight is preferred.

In the invention of the present application, the above chemical formula:
The fast dissolving dye represented by Chemical Formula 1 is an existing chemical substance, Food Blue No. 1 (Brilliant Blue FCF), and the slow dissolving dye represented by the above chemical formula, Chemical Formula 2 is the food blue No. 1 described above. And the mixing ratio of both dyes is 1:
It is optional as long as it is in the range of 99 to 99: 1, and its content as an active ingredient is about 1 to 20% by weight or more.
The range is preferably about 2 to 10% by weight from the viewpoint of the function as a solid detergent.

Further, the solid detergent for flush toilets according to the invention of this application includes a dissolution rate regulator, a specific gravity regulator, a fragrance,
It goes without saying that various components such as other extenders can be blended.

[0011]

The solid cleaning agent for flush toilets according to the invention of the present application can provide an appropriate coloring of the stored water in the initial stage of being used by putting it into the water tank of the flush toilet. Up to the stage, it is possible to stabilize the coloration of the stored water to an appropriate level.

[0012]

The solid cleaning agent for flush toilets according to the invention of the present application will be described in detail below with reference to Examples and Comparative Examples. Examples 1 to 3 and Comparative Examples 1 to 2 Each component was heated and melted at about 80 ° C. and mixed at a ratio shown in Table 1 below, and 45 g was poured into a mold having an appropriate shape to be cooled and solidified. A flush toilet solid detergent according to the invention of this application and a comparative flush toilet solid detergent were obtained. Then, the coloring density of the water stored in the flush toilet according to each of the examples and the comparative examples was observed by the following test method. Table 2 shows the results.

Color concentration test method: The solid detergents for flush toilets of the respective examples and comparative examples were put into a flush toilet water tank, and the number of flushes of the flush water was 5, 50, 100 times.
The coloring density of the stored water at each of the 200 times and the 500 times was visually determined.
