Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a long-lasting powder automatic cleaning agent for flush toilets.

Conventional automatic toilet flushing and cleaning agents that have been commercialized include those based on polyethylene glycol (hereinafter abbreviated as PEG) with a molecular weight of 4,000 to 20,000, those based on urea, polyoxyethylene, and polyoxypropylene. There are some that are mainly made of copolymers, but all of them must be placed in some kind of container to retain their shape after being heated and melted. In addition, because solubility and persistence are controlled only after dissolution in water,
Currently, a special container is required, and solubility can only be controlled by integrating the container. The nine solubilized fragrances are PEG.

Since the specific gravity is lighter than dyes and water, it diffuses into the water more quickly than they do from the outlet at the top of the container, so the scent is strong at the beginning of use of these automatic cleaning agents, but the scent becomes weaker as it progresses to the middle to later stages of use. It has its drawbacks.

The purpose of the present invention is to improve the above-mentioned conventional drawbacks, to maintain a good balance between fragrance, color tone, and washability, and because it is a powder, it is easy to work with during production. To provide a method for producing an automatic cleaning agent which eliminates the need for a container by deaerating and filling the agent, and which can be boiled and thrown into a water tank during use, thereby saving the trouble of recovering the container.

The present invention uses an 8 to 40 mole adduct of ethylene oxide (abbreviated as KO) or a polyoxyethylene sorbitan fatty acid ester, or a molecular weight 6
After adding and dissolving 1 to 20,000 polyoxyethylene and polyoxypropylene copolymers or a mixture thereof, 1 to 301 G (the same weight - 1 or less based on the total amount of the finished cleaning agent) is added.
The first step involves controlling the solubility and powdering by adding known dyes and cleaning aids, and adding polyethylene oxide (PE) with an average molecular weight of 3 million to 6 million.
(abbreviated as O) 2-20G or C11 or higher saturated fatty acid sodium salt or oleic acid sodium salt 0.2-5- or a mixture thereof as an essential component, and a synthetic polymer thickener or a mixture 10-40- A powder aromatic automatic cleaning agent for flush toilets, which consists of a second step of mixing the powder made in the first step, and a third step of vacuum or deaerating filling into a water-soluble film bag. I will provide a.

In the present invention, at least one of the above-mentioned specific nonionic surfactants is used to make the liquid perfume latent. This nonionic surfactant not only controls the rate of dissolution of fragrance into water, but also works synergistically with PEO, sodium salt of C11 or higher saturated fatty acid, or sodium oleate, and a synthetic polymer thickener, as described below. This prevents excessive diffusion that occurs due to the light specific gravity of the fragrance itself.

EO of polyoxyethylene alkylphenol ether as a nonionic surfactant used in the present invention
The number of moles added is 8 to 40 moles, and the amount used is 1 to 3
It is 0chi.

If the number of moles of EO added is less than 8, the chain point will be too low, which is not preferred in the summer when the water temperature rises. Further, if the number of moles of EO added is 40 or more, the properties as a surfactant are unfavorable. In addition, the addition rate is determined by the addition rate of fragrance,
The addition rate of fragrance is 5 from the point of view of deodorization and fragrance, which is the effect of fragrance.
If the amount is between 209g and 209g, it is difficult to formulate a formulation due to the stability of the formulation, destruction of fragrance solubilization, leaching, etc. If it is less than 5 inches, it has no deodorizing or fragrance effect. Therefore, the addition rate of the E08-40 mole adduct of polyoxyethylene alkylphenol is 1-30. If it is less than 1, it is difficult to maintain the solubilization of a fragrance of 5 or more for a long period of time, and if it is more than 30, it is uneconomical. The same applies to the addition rate of polyoxyethylene sorbitan fatty acid ester and polyoxyethylene/polyoxypropylene copolymer having a molecular weight of 6,000 to 20,000. If the molecular weight of the polyoxyethylene/polyoxypropylene copolymer is less than 6,000, it will have weak properties to stably supplement fragrances, and if it is more than 20,000, it will have poor solubility and weak properties as a surfactant, making it unsuitable. Appropriate.

The perfume solubilized as described above is powdered by adding known colorants and cleaning aids.

Pigments act as a barometer to indicate the longevity of an aromatic cleaning agent, and can be added as necessary to increase product value. The cleaning aids are phosphate, silicate, and sulfate groups used in the triblend of general detergents, and the triblend is sufficient for powdering.

The powdered fragrance mixture in the first step has an average molecular weight of 300.
10,000-6,000,000 PICO2-20- or C0 or more saturated fatty acids) IJum salt or sodium oleate 0
．． One or a mixture of 2 to 5 is an essential ingredient, and one or a mixture of synthetic polymer thickeners such as cellulose ether, polyvinyl alcohol, and sodium polyacrylate is added to 10 to 40. After the merging is carried out, a water-soluble film such as polyvinyl acetate, polyvinyl alcohol, polyvinylpyrrolidone, ethyl cellulose, etc. is filled into a bag by vacuum or degassing. PIO and sodium salts of saturated fatty acids and sodium oleate are responsible for the shape retention of the detergent when placed in an aquarium. In other words, since the cleaning agent added to water is vacuum-filled or degassed into a water-soluble film, it is weakly compressed by water pressure in the water layer, and then comes into close contact with the water, causing the soluble film to dissolve. .

As soon as water reaches the surface of the cleansing agent, a thin layer of gel forms around the cleansing agent due to the action of the synthetic polymer thickener. This thin layer of gel passes through the film-like structure of the gel polymer to the outside of the detergent, allowing it to absorb the relatively low-molecular fragrance,
The dye, surfactant and cleaning aid are diffused at a constant rate. If the gel layer is further thickened, the gel layer will be 1 cm thick. This gel layer is partially destroyed by physical forces, ie, water flow caused by outflow and water supply that occurs when the tank valve is opened, and is dispersed into the water. However, due to the action of PEo, saturated fatty acid sodium salt, or sodium oleate, and the synthetic polymer thickener, it settles to the bottom of the water tank. For this reason, when the am is suitable for cleaning, the concentrated detergent solution will settle around the gel layer of this detergent, and the osmotic pressure difference will decrease.
Prevents over-elution by reducing the diffusion rate.

As for the interior of the cleaning agent, the water is released by diffusion to the outside and enters into the detergent by the amount of the nine fragrances and other substances, contrary to the above. Furthermore, a new gel layer is repaired by water penetration directly below the physically destroyed gel layer. However, in this case, the shape retention of the synthetic molecular layer agent alone is poor, and the gel layer gradually flows down and spreads laterally, so the gel layer becomes thinner above the cleaning agent, and is repaired one after another and flows down. As a result, everything turns into a gel, which is weak against physical forces and causes excessive elution. To prevent these, PEO and sodium salt of saturated fatty acid or sodium oleate are essential ingredients. That is, PEO becomes a strong resin-like material against water intrusion and maintains shape retention. For this purpose, 2 to 209 g of PEO with an average molecular weight of 3 million to 6 million is suitable. If the average molecular weight is less than 3 million, it becomes like a soft resin, and in order to improve shape retention, it is necessary to add it at a high concentration. If it is more than 0,000,000,000,000,000 or more, it is not preferable because it inhibits the gel-forming ability of the synthetic polymer thickener. If the addition rate is less than 2, the shape retention is poor; if it is more than 20, the gel forming ability of the synthetic polymer thickener will be inhibited, as mentioned above, and it will be impossible to release an appropriate amount of perfume or detergent. Become. Unlike synthetic polymer thickeners, sodium salts of C11 or higher saturated fatty acids or sodium oleate maintain shape retention because they form gels with no fluidity.

Below Ctt, the gel-forming ability is weak, and potassium salts or sodium salts of unsaturated fatty acids other than sodium oleate also have no or weak gel-forming ability. If the amount added is less than 0.211, it will be solubilized by the surfactant and it will be difficult to maintain shape retention, and if it is more than 5, the shape retention part inside the gel will crack, and the broken pieces will break down into the gel. The product becomes more detached, is discharged into the toilet, and loses its commercial value.

Examples of synthetic polymer thickeners include cellulose ether, polyvinyl alcohol, and sodium polyacrylate, but the types that can be used in the present invention are: - Water-soluble in nature, and highly concentrated liquid. is not limited as long as it exhibits non-Newtonian properties and forms a fluid gel. The addition rate is 10-40. If it is less than 10, the gel layer is too weak, and if it is more than 40, it is uneconomical.

The cleaning agent is filled into a water-soluble film by vacuum or degassing, but the degree of filling is limited to 1, when each particle and the film are in close contact with each other.
I-transformation is sufficient, and a high degree of vacuum is not required. When this operation is carried out and the surface is put into water, it does not form one block but forms two to three blocks or blocks of several centimeters or less, which is not preferable. Also, the shape is cylindrical, cubic,
Although rectangular parallelepiped, spherical, etc. shapes are preferred, the present invention is not limited to such shapes. Water-soluble films are also not limited as long as they have good sealability and are soluble in water.
