Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a solid detergent for toilets, and more particularly to a solid detergent for toilets, which comes into contact with running water so that a cleaning component is released into the bath, thereby cleaning the toilet bowl.

Currently, there are many deodorizing and cleaning agents for deodorizing and cleaning toilets, such as deodorizing bowls for men's toilet bowls made of baladichlorobenzene containing fragrances, fragrances, dyes, and cleaning ingredients. Deodorizing cleaners for flush toilets, which are made by storing solid or liquid substances contained in a suitable container and being immersed in a flush tank, are known and used.

However, in the product (2) using baladichlorbenzene, the baladichlorpenzene itself has a cleaning effect, and the amount of fragrance that can be contained is small, so the deodorizing effect is also insufficient.

- In the water tank (2) Used by dipping (2) You can expect a certain degree of cleaning effect, but installation and removal in the tank requires troublesome work such as opening the lid Z of the tank. Moreover, it often stains the surrounding area and clothes.

Under the above circumstances, there is a need for a toilet cleaner that has both cleaning and deodorizing effects and is easy to handle. It cannot be released.

2) When exposed to water, it becomes soft and deformed, which can also cause drains to become clogged.

3) Difficult to mold.

For these reasons, the current situation is that nothing that can be put to practical use has yet been obtained.

Furthermore, in the case of solid detergents that perform both cleaning and deodorizing actions, it is of course desirable that both of these actions continue until they disappear (3).

The present invention was made against the background as described above, and
The purpose is to provide a solid toilet cleaning agent that has cleaning and deodorizing effects over a long period of time and even until it disappears, does not deform during use, and can be easily manufactured. = There is.

The characteristics of the present invention are that the HLB is 13 to 20 and the number average molecular weight (hereinafter simply referred to as "molecular weight") is 2,000.
It contains 20% by weight or more of a nonionic surfactant of 0 to 20,000 and an alkali metal salt of stearic acid.

The present invention will be specifically explained below.

In the present invention, at least 2ON amount of a nonionic surfactant having an HLB of 13 to 20 and a molecular weight of 2,000 to 20,000, and at least an alkali metal salt of stearic acid such as a sodium salt or a potassium salt are used. Ichiyu and
A solid toilet cleaning agent is composed of other additives such as surfactants, fragrances, dyes, metal compound scavengers, and fillers, which are added as necessary. That is, the nonionic surfactant is heated and melted, and an alkali metal salt of stearic acid is added thereto. Preferably, in order to enhance the dispersibility of the alkali metal salt of stearic acid and further improve the effects of the present invention, the alkali metal salt of stearic acid is produced by adding stearic acid and an alkali metal hydroxide in the form and melt-mixing them. . Then, if necessary, additives such as other surfactants, fragrances, dyes, metal compound scavengers, bulking agents, etc. are added and mixed, molded, and then cooled and solidified to obtain a solid toilet cleaning agent.

Since the solid toilet cleaning agent of the present invention is as described above, when it is splashed with water, an appropriate amount of nonionic surfactant is released into the water, thereby cleaning the inside of the toilet bowl, etc. As a result, a deodorizing effect is obtained. In addition, since it contains an alkali metal salt of stearic acid that has an excellent shape-retaining effect on this nonionic surfactant, the cleaning agent does not soften when water is splashed on it, and does not cause the surface to become sticky. Furthermore, since the nonionic surfactant (5) is usually a solid having a melting point of about 40 to 70°C, it is easy to melt and mold it.

In addition, in the cleaning agent of the present invention, since the nonionic surfactant itself has an appropriate bath solubility in water, the above-mentioned cleaning and deodorizing effects are exerted until the nonionic surfactant disappears.

The reason why the nonionic surfactant in the detergent of the present invention is suitable for bathing is that its HLB is 13 to 20 and its molecular weight is 2,000 to 20,000.
If the molecular weight is less than 13, or if the molecular weight exceeds 20,000, the elution ratio will be too small and the necessary cleaning action will not be exerted, and if the molecular weight is less than 2.000,
The ratio of bathing out becomes excessive, and in order to obtain a usage period of, for example, one month, a large molded product is required, and the cleaning action of the nonionic surfactant is not effectively utilized.

The preferred molecular weight of this nonionic surfactant is 4.000.
~14,000.

Specific examples of such nonionic surfactants include polyoxyethylene lauryl ether, cetyl (6) ether, octylphenyl ether, nonylphenyl ether, or stearic acid ester, or oxyethylene-oxybrobylene block polymer, and others. These can be used alone or in combination of two or more. Among these nonionic surfactants, C-nioxyethylene-oxypropylene block polymers are preferred, and even when two or more of them are used in combination, it is desirable that one of them is this.

The proportion of this non-ionic surfactant in the entire cleaning agent is 20% by weight or more, and if the proportion is lower than this, no cleaning effect can be obtained. A preferred proportion is 40% by weight or more.

Moreover, as the alkali metal salt of stearic acid, sodium salt, potassium salt, etc. can be used.

This stearate is usually 20% by weight or less, preferably 1 to 2 parts by weight per 100 parts by weight of the nonionic surfactant.
The proportion is 0 parts by weight. In terms of manufacturing, it is preferable to add stearic acid and alkali metal hydroxide to the nonionic surfactant (7) in the form of stearic acid and alkali metal hydroxide, and at this time, adding a small amount of water facilitates molding. Good solubility and shape retention are obtained. Further, when adding stearic acid and alkali metal hydroxide in the form, it is preferable that stearic acid is in excess of 10 mol % or less relative to the alkali metal hydroxide.

Among the additives added as necessary, other surfactants are used to obtain an overall greater cleaning effect in addition to the cleaning effect of the nonionic surfactant, and specific examples thereof include: Examples include anionic surfactants such as sodium horse chestnut benzene sulfonate, sodium lauryl sulfate, and sodium polyoxyethylene alkyl ether sulfate, alkyl betaines such as lauryl betaine and stearyl betaine, and alkyl amine oxides such as lauryl dimethylamine oxide. The proportion is usually 10% by weight or less.

Alkyl betaine, alkyl benzalkonium salt
When added, it becomes a cleaning agent that also has a bactericidal effect.

Fragrances completely mask bad odors and leave a fragrance in the toilet. Plant essential oils, blended fragrances, baladichlorobenzene, etc. are usually used in a proportion of 10% by weight or less. Further, decaling substances that react with malodorous components of the toilet and produce a foul odor, such as organic acids such as wood acetic acid and malic acid, zinc chloride, etc., may also be used. The nonionic surfactant has a good retention property for these fragrances, and when it is sprayed with water, it emits a strong fragrance.

Dyes are used to give running water a sense of cleanliness, and include blue acid dyes such as Hood Blue and Turquoise Spruce,
Direct dyes are preferably used, and their content is less than 10% by weight.

The metal compound scavenger is ethylenediaminetetraacetic acid, citric acid, etc., and by adding it in a proportion of 1 to 5% by weight, it is possible to remove stubborn stains caused by calcium compound deposition.

As the filler, water-soluble or sparingly soluble organic compounds or inorganic compounds or powders thereof can be used, but particularly water-soluble compounds such as urea, melamine, (9) mirabilite, salt, and borax are preferably used. It will be done. Its content is less than 50% by weight. By using an extender as a component, it may be possible to completely adjust the bath dissolution rate, surface hardness, etc. of the entire cleaning agent.

When the cleaning agent of the present invention is stored in a fluid-permeable container or placed directly in the toilet bowl without being stored, the cleaning component will be eluted when flushing water or urine is splashed on it, or when the cleaning agent is placed in a flush toilet. Near the water inlet of the wash water tank,
Alternatively, in the case of a toilet with a hand wash, place it near it (flea), the cleaning ingredients will be eluted when water is flowing or when ≦2 bottles are splashed on the toilet bowl, which will eventually lead to the inside of the toilet bowl and this. It is possible to clean the drainage channel, that is, to prevent the accumulation of dirt over a long period of time, to remove the adhering dirt, and to keep the toilet clean.

Examples of the present invention will be described below, but the present invention is not limited thereto.
