Description

[Detailed description of the invention]

TECHNICAL FIELD The present invention relates to a solid detergent composition for a flush toilet, which is used by being put into the water tank of a flush toilet without using a container. As the standard of living improves, the development of sewage systems and the use of flush toilets progress, and the use of water-storing flush toilets continues to expand. Under these circumstances, how to maintain the hygiene of toilet bowls has become an issue. Conventionally, as a solution to this problem, plastic containers filled with an aqueous solution or solid detergent are commercially available. All of these systems utilize the airtightness of the container to achieve slow solubility, and when installing these systems, users are burdened with having to remove the lid of the heavy ceramic water tank. In particular, liquid type containers must be tipped over when installed in a water storage tank, so if they are not installed carefully and properly, the cleaning solution may spill all at once.Also, there is a risk of a rise in temperature or a change in the amount of cleaning agent. It also has the disadvantage that the amount of dripping changes depending on the amount of water. Furthermore, if you take conventional containerized solid detergents out of the container and put them directly into water, they will all dissolve in 2 to 3 days, so these solid detergents maintain their cleaning power for a considerable number of days. It was completely unsuitable for that purpose. With the aim of gradually eliminating the above-mentioned conventional drawbacks, the present invention has been developed as a result of extensive research into a solid detergent composition that is extremely slowly soluble in water and can be used by directly adding it to the water tank of a flush toilet. It is something that has been discovered and completed. That is, the present invention comprises 40% or more of one or more types of polyoxyethylene distearate having an added mole number of ethylene oxide of 91 to 230, and polyoxyethylene sorbitan monostearate and/or a polyoxyethylene sorbitan monostearate having an added mole number of ethylene oxide of 6. 0.1 to 60% polyoxyethylene sorbitan tristearate with an added mole of ethylene oxide of 20
It relates to a solid cleaning agent composition for an input type water storage type flush toilet, which is characterized by containing: Since the present invention has the composition as described above,
Because it is extremely slowly soluble in water, there is no need to utilize the airtightness of a container to slowly dissolve it, as in the past, and no container is required. Therefore, there is no need to take off and attach the lid of a heavy water storage tank when using the water tank, and the purpose can be achieved by simply pouring water into the water tank through a small hole in the lid. In the present invention, the term "injection type" refers to a product that is used by directly putting it into the water tank of a flush toilet without putting it into a container. The injected solid detergent composition according to the present invention sinks to the bottom of the water storage tank and gradually dissolves from the surface, and is fixed to the bottom surface of the water storage tank without being rolled up by the water flow caused by drainage or inflow of the water tank. It has the characteristic that it slowly dissolves without forming floating matter or precipitates, and continues to function as a solid cleaning agent for flush toilets for a considerable number of days. In the present invention, various dyes can be used as necessary. Its usage is
If it is less than 2%, the coloring will be too light, and if it exceeds 8%, it will be too dark, and 2 to 8% is a functional content rate for determining the presence or absence of a detergent. This discrimination method using dye is only one example, and other means (presence or absence of foaming of the cleaning agent) may be used. In the present invention, polyoxyethylene sorbitan monostearate (number of moles of ethylene oxide added: 6) and polyoxyethylene sorbitan tristearate (number of moles of ethylene oxide added: 20) both have a long-lasting effect and prevent deformation. They may be used in combination or alone. However, if the content exceeds 60%, the duration will be too long compared to other compositions, creating an imbalance in the dissolution rate with dyes, fragrances, etc., and eventually, although it will dissolve in water, fragrances will remain However, it is preferable that the content is up to 60%, as some of it becomes a residue that does not elute the dye and becomes a floating substance, which is undesirable. In the present invention, if the content of polyoxyethylene distearate is 40% or more, it can function as a solid cleaning agent for water storage type flush toilets. This blending amount is preferably up to 97% when considering the content of fragrances and dyes. In the present invention, if the number of moles of ethylene oxide added is less than 90, the duration is short, and if it exceeds 230, the viscosity increases during molding, making molding difficult. Since the present invention relates to a solid detergent composition, it will be difficult to obtain a product if it cannot be easily molded into a solid form. Therefore, the number of moles of ethylene oxide added is preferably from 91 to 230, and compounds within these ranges may be mixed. In the present invention, the type of fragrance is arbitrary. If the amount exceeds 20%, the solid detergent becomes semi-solid, making it difficult to mold, poor stability over time, and fragrance oozing out, and other disadvantages such as a shortened duration. Therefore, the appropriate content is 20% or less. To produce the solid detergent composition of the present invention, for example, polyoxyethylene distearate, polyoxyethylene sorbitan monostearate, or polyoxyethylene sorbitan tristearate alone or a mixture of both are heated at 55 to 75°C. Warm to. After confirming the slurry, a mixture of dye and fragrance is added and stirred. Thereafter, the solid detergent composition of the present invention can be obtained by pouring it into a mold of any shape, cooling and removing it from the mold. The present invention will be explained in detail below using Examples, Comparative Examples, and Experimental Examples. Examples 1 to 10 and Comparative Examples 1 to 6 A mixture of polyoxyethylene distearate and polyoxyethylene sorbitan monostearate and/or polyoxyethylene sorbitan tristearate mixed in the proportions shown in Table 1 below. After heating to 55 to 75°C and confirming the slurry, a mixture of dye and fragrance in the proportions shown in Table 1 is added and stirred. Thereafter, it was poured into a mold of an arbitrary shape, cooled, and removed from the mold at an appropriate time to obtain solid detergents of the present invention and Comparative Examples 1 to 6. Example 1 A pipette washing tower (H:
64cmφ: 19cm) and the number of days until it dissolved was defined as the number of days it lasted. The concentration of coloring due to the dye was determined 1 day and 20 days after the injection, and every 10 days after that, the pipette washing tower was filled with water and the water supply was stopped, and the concentration was determined visually after 24 hours. The results are also listed in Table 1 below.
