Description

The present invention relates to a fragrance cleaning agent for flush toilets and a method for producing the same, and more particularly to a fragrance cleaner for flush toilets comprising a central axis layer and two or more layers sequentially covering the periphery thereof and a method for producing the same.

A conventional fragrance cleaning agent for flush toilets is a composition mainly composed of a surfactant, a fragrance, and a pigment, and is formed of a single solid layer, and thus has the following disadvantages. For example, these cleaning agents are used by being installed in a container on a water washing tank. Usually, these cleaning agents are wrapped in a packaging film, and when refilling, the packaging film is torn out and installed in the container. become. However, when taking out a soft cleaning agent that is difficult to get out of the bag, or when the cleaning agent that comes out of the bag falls down, it may directly touch the cleaning agent. This dye has a problem that unpleasant sensation remains for a long time because it is difficult to remove even after washing with soap or the like.

Next, when the amount of the liquid component is increased, the shape retention is poor and the cleaning agent is soft and there is a problem of stickiness, and when a fragrance is blended, it is blended almost uniformly throughout the solid layer. It was difficult to respond to increasing the scent or increasing the scent at the end of use. Furthermore, in the case of detergents with pigments, it is difficult for the user to recognize the compounding state even if a minor component such as a chelating agent or an enzyme is added, and to increase the commercial value, and to remove the yellowing of the toilet. Therefore, since the bleaching agent and the coloring agent chemically react with each other, they cannot be mixed in a single cleaning agent.

Therefore, the present invention can solve the problem that the pigment easily adheres during handling and the problem that the amount of the liquid component cannot be increased, and the scent can be controlled, and the commercial value is improved by the addition of the trace component. It is an object of the present invention to provide an aroma cleaning agent for flush toilets and a method for producing the same.

As a result of diligent research to achieve this object, a cleaning agent that can solve the above problems can be obtained by using a cleaning agent composed of a plurality of layers having a central axis so that the components in the layers are different between any plurality of layers. In addition, it was found that these detergents can be easily produced mechanically by devising a combination of a plurality of hollow molds, thereby completing the present invention.

That is, the first invention of the present invention is a solid fragrance cleaning agent for flush toilets comprising at least a surfactant, a pigment, and a fragrance, and has a central axis layer, and the following layers around the axis of each layer The fragrance cleaning agent for flush toilets comprises two or more layers sequentially covered, and at least one component in the layers is different between at least one combination of two layers.

Here, the two layers of “at least one combination of two layers” can be arbitrarily selected, and may be adjacent two layers or may be separated from each other. For example, the central axis layer and the outermost layer may be used. In addition, since it is “two layers of at least one combination”, the components may be different in three or more layers, and the components may be different in two layers of a plurality of combinations. On the other hand, “one component is different” includes not only the case where the type of the component is different, but also the case where the type or amount of the component is different even if the type is the same. Of course, a difference depending on the presence or absence of the component is included. Moreover, since it is "at least one", of course, a some component may differ. In addition, the cross-sectional shape of the cleaning agent composed of two or more layers (preferably two or more and several to several tens of layers) is not limited. For example, a circle, an ellipse, a triangle, a rectangle, a polygon, a star shape, a heart shape and the like are included. Further, the sectional shape of each layer of the cleaning agent may be a combination of two or more of these sectional shapes. For example, the central axis layer is a star, the outer layer is circular, the central axis layer is a star, the next layer is triangular, the next layer is circular, the central axis layer is a heart shape, and the next layer is square Etc. are exemplified.

The surfactant used in the present invention may be any of so-called nonionic surfactants, anionic surfactants, cationic surfactants, zwitterionic surfactants, and other surfactants. Activators and anionic surfactants are preferred. In addition, these surfactants may be used independently and may be used in mixture of 2 or more types.

The dye used in the present invention is not particularly limited as long as it is a water-soluble dye. Specifically, Blue No. 1, Blue No. 2, Blue No. 3, Yellow No. 3, Yellow No. 4, Yellow No. 202, Red 106 No., Red No. 2, Red No. 3 and the like.

Although the fragrance | flavor used for this invention is not specifically limited, Specifically, synthetic fragrance | flavors, such as natural fragrance | flavors, such as rose oil, grapefruit oil, and pine oil, or limonene, and mixtures thereof are illustrated.

In the present invention, chelating agents, enzymes, deodorants, water repellents, and the like may be blended as builders, dissolution regulators, and other minor components. Furthermore, other compounding agents such as a lubricant and a release agent may be blended.

As the builder used in the present invention, any water-soluble filler can be used. Specifically, alkali metal chlorides, carbonates, bicarbonates, sulfates, phosphates, borates. , Water-soluble inorganic fillers such as silicates, carboxylic acids having 2 to 10 carbon atoms, hydroxycarboxylic acids having 2 to 10 carbon atoms, organic acids such as polycarboxylic acids and hydroxypolycarboxylic acids, and salts thereof And water-soluble organic fillers such as aminocarboxylic acids having 2 to 10 carbon atoms, aminopolycarboxylic acids or polyaminocarboxylic acids, or salts thereof. In addition, these builders may be used independently and may be used in mixture of 2 or more types.

Examples of the dissolution regulator used in the present invention include carboxymethylcellulose salts, water-soluble and thermoplastic oligomers and polymers such as gelatin and agar.

If comprised in this way, according to the objective, since the kind, the property, and quantity of a component mix | blended with each layer can be changed, the said subject can be solved as shown below. For example, (1) If a pigment is not arranged in the outermost layer of two or more concentric axis layers and a pigment (for example, blue) is blended in the inner layer, the color of the washing water (blue) can be secured. In addition, even if the detergent is shaken, the effect of preventing the pigment from adhering is obtained, and the problem of long-term discomfort given to the user can be solved.

(2) If the amount of liquid components (excluding fragrances and pigments, the same shall apply hereinafter) is increased in the inner layer and more solid components are added in the outer layer, the liquid component is in the inner layer. Because it is trapped, it can solve the problem of shape retention and stickiness of the cleaning agent. (3) Even when blending a fragrance, if more fragrance is blended in the outermost layer, the scent at the beginning of use is increased, and the inner layer If more fragrances are added, it is possible to increase the late scent. In addition, (4) If you do not mix pigments in the outermost layer but mix colored trace components (chelating agents, enzymes, etc.), you can let the user recognize the blended state and increase the commercial value. (5) The chemical reaction component can be separated and mixed in each of the two layers to prevent chemical reaction due to the component. Further, a combination of two or more of the combinations (1) to (5) is also possible.

Of the present invention, the second invention is an aroma cleaning agent for flush toilets characterized in that the pigment is different between two layers of at least one combination of the first invention. In this way, if configured, the color to be mixed in each layer becomes a mixed color in the wash water at the time of use, and the product is given a design effect by color layer separation, while at the time of use it is washed with a fresh mixed color wash water. can do. In addition, as described above, if a pigment is not blended in the outermost layer and a pigment is blended in the inner layer, an effect that the pigment does not adhere can be obtained even if the detergent is shaken.

3rd invention among this invention is the fragrance cleaning agent for flush toilets characterized by the quantity of a liquid component and / or the quantity of a fragrance | flavor differing between the two layers of at least 1 combination among 1st invention. is there. In this way, even if it is desired to increase the amount of the liquid component, the component is added to the inner layer, and the solid component is added to the outer layer (for example, the outermost layer). In this way, the problem of the soft and sticky cleaning agent that occurs in the conventional single layer cleaning agent can be solved. As for the fragrance, for example, if more fragrances are blended in the outer layer, the rise of fragrance can be accelerated, and if more fragrances are blended in the inner layer, the rise of fragrance can be delayed. A combination of two layers having different liquid component blending amounts and two layers having different flavor blending amounts is also possible.

A fourth invention of the present invention is characterized in that, in the first invention, a trace amount component of a fragrance cleaning agent for flush toilets is blended in a layer of an outer portion between two layers of at least one combination. It is an aromatic cleaning agent for flush toilets. Thus, if comprised, it can make a user recognize the compounding state and can raise a commercial value. For example, when a trace amount of colored components (such as a chelating agent, an enzyme deodorant, or a water repellent) is blended in the outermost layer, a pigment is not blended in that layer, and a pigment is blended in the inner layer. It is. In this case, the design effect of the cleaning agent is enhanced while securing the color of the cleaning water at the time of use by the pigment of the inner layer.

The fifth invention of the present invention is for a flush toilet characterized in that components that chemically react with each other are mixed and separated into one and the other of at least one of the two layers of the first invention. A fragrance cleaner. If comprised as mentioned above, even if the component which carries out a chemical reaction mutually is contained in the washing | cleaning agent, since these components are isolate | separated into two layers, they do not react chemically. As a result, this cleaning agent can be stored for a long period of time without causing functional changes in the components due to chemical reactions, and even if these components dissolve in running water during use, they are instantly mixed partially. The reaction between these components does not occur so much and the function of each component is maintained. For example, in the case of a cleaning agent that contains a bleaching agent and a pigment separated into two layers, the function of the bleaching agent for removing yellowing of the toilet and the function of the coloring agent for coloring the cleaning water are the long-term storage conditions of the cleaning agent. Is also maintained during use of the cleaning agent. Other examples of the chemical reaction component include a combination of an acid and a base.

According to a sixth aspect of the present invention, the inner diameter of the inner partial mold is such that the inner diameter of the outer partial mold is adjacent to a hollow partial mold (hereinafter simply referred to as a partial mold) that serves as the central axis. Using a mold having a structure in which partial molds are sequentially arranged so as to become large, and each outlet part of the outer partial mold is tapered in the vicinity of the outlet of the adjacent inner partial mold, The method for producing a fragrance cleaning agent for flush toilets according to the first, second, third, fourth, or fifth aspect of the present invention, characterized by performing extrusion molding.

With the above configuration, when the cleaning material is pressed into each partial mold from the extruder, the raw material passes through the mold and reaches the mold outlet. Since each outlet portion of the taper is tapered near the outlet of the adjacent inner partial mold, the raw material of each layer separated by the mold wall up to the outlet is that of the outer layer near the outlet. It is compressed into a layer and molded. As a result, the respective layers are integrally laminated concentrically, and a cleaning agent having no gap between the respective layers is easily formed continuously.

As described above, according to the cleaning agent of the present invention, the type, nature, and amount of components to be blended in each layer can be changed according to the purpose, so that the above-mentioned problems that could not be solved conventionally can be solved. For example, (1) If the pigment is not arranged in the outermost layer of two or more concentric shaft layers and the pigment (for example, blue) is blended in the inner layer, the color of the wash water (blue) is secured. In addition, even if the detergent is shaken, the effect of preventing the dye from attaching is obtained, and the problem of long-term discomfort given to the user can be solved.

(2) If the amount of liquid component is increased in the inner layer and a larger amount of solid component is added in the outer layer, the liquid component is confined in the inner layer. In addition, the cleaning agent is soft and can solve the sticky problem. (3) If more fragrance is added to the outermost layer, the scent at the beginning of use is increased, and if more fragrance is added to the inner layer, it is used. It is possible to increase the late scent (or vice versa). In addition, (4) If the pigment is not blended in the outermost layer, but it is blended with colored trace components (chelating agents, enzymes, etc.), the blended state can be recognized by the user, increasing the commercial value and (5) It is possible to separate and mix the chemical reaction component in each of the two layers, prevent the chemical reaction, and maintain the function of the component. Further, a combination of two or more of the combinations (1) to (5) is also possible.

Further, according to the method for producing a cleaning agent of the present invention, when the cleaning material is press-fitted from the extruder into the partial mold that is the central axis and the partial mold that is sequentially arranged around the partial mold, the raw material is the mold. It passes through the inside and reaches the mold outlet. At that time, each outlet part of the outer partial mold is tapered near the outlet of the adjacent inner partial mold. The raw material of each layer separated by (1) is molded by compressing the outer layer from the outer layer near the respective outlets into the inner layer. As a result, the respective layers are integrally laminated concentrically, and a cleaning agent having no gap between the respective layers is easily formed continuously.

FIG. 1 is a perspective view of a cleaning agent that forms two layers (a central axis layer and an outer layer) according to the first embodiment of the present invention. FIG. 2 is a schematic view showing the main part of an extruder used in the production method according to the second embodiment of the present invention, wherein 1 is a mold and 2 is an extruder body. Reference numeral 1a denotes a partial mold serving as a central axis, and reference numeral 1b denotes an outer partial mold. The inner diameter of the mold 1b is larger than the outer diameter of the mold 1a, and is tapered at the outlet of the mold 1a. 2a is an extruder body connected to the mold 1a, and 2b is an extruder body connected to the mold 1b. FIG. 3 is a schematic view showing a raw material component kneader and a metering feeder. 3 is a twin-screw kneader, 4 is a powder component metering feeder, and 5 is a liquid component metering pump.

The cleaning agent forming the two layers (the central axis layer and the outer layer) according to the first embodiment (hereinafter simply referred to as the two-layer cleaning agent) is the second embodiment using the extruder shown in FIG. According to the following method. That is, first, the powder component of the raw material is weighed by the metering feeder 4, and the liquid component is metered by the metering pump 5 and sent to the biaxial kneader 3, where it is sufficiently stirred and kneaded. In this case, various kneading raw materials having different raw material compositions can be obtained by changing the types, properties and amounts of the components. Next, among the kneaded raw materials, the raw material that becomes the central axis layer of the cleaning agent is pumped from the biaxial kneader 3 to the mold 1a via the extruder body 2a, and the raw material for the outer layer is the biaxial kneader. 3 is pumped to the mold 1b via the extruder main body 2b. However, since the mold 1b is tapered at the exit portion of the mold 1a, the raw material in the mold 1b is compressed there. Pressed against the raw material from 1a. As a result, the two layers formed by both raw materials are filled with a gap due to the mold wall of the mold 1a that has been separated from each other, and an integrated molded body in which the two layers are in close contact with each other. This molded body is used after being cut into a desired size.

EXAMPLES Hereinafter, although this invention is demonstrated further more concretely using an Example, this invention is not limited to these Examples.

(Reference Example 1 and Comparative Example 1) In Reference Example 1 and Comparative Example 1, a pigment is blended in a central axis layer (referred to as a central layer in Table 1 hereinafter, the same in other tables), and an outer layer (in Table 1). The outer layer, hereinafter the same in other tables) relates to a two-layer detergent that does not contain a dye. Samples of Reference Example 1 were coconut oil mixed fatty acid salt (manufactured by Daiichi Kogyo Seiyaku Co., Ltd.) and polyethylene glycol (PEG 6000P made by Daiichi Kogyo Seiyaku Co., Ltd.) as the surfactant, and neutral anhydrous sodium sulfate (Shikoku Kasei Co., Ltd.) as the builder. ), A carboxymethyl cellulose salt as a dissolution regulator, Blue No. 1 (manufactured by Mikuni Sumitomo Chemical Co., Ltd.) as a pigment, and a fragrance mixture as a fragrance, blended as shown in Table 1, and the method shown in the second embodiment It is manufactured by. The sample of Comparative Example 1 was produced in the same manner based on the formulation in Table 1. Each sample of Reference Example 1 and Comparative Example 1 has an outer layer edge diameter of 32 mm, a central axis layer edge diameter of 22.6 mm (volume ratio 1: 1), and a length of 22.0 mm. was gotten.

(Reference Examples 2, 3, and 4) Reference Examples 2, 3, and 4 relate to a two-layer detergent in which different dyes are blended in the central axis layer and the outer layer, and each sample is yellow 202 (1) as the dye. It was manufactured in the same manner as the sample of Reference Example 1 except that it was blended as shown in Table 2 using Red No. 106 (manufactured by Mikuni Sumitomo Chemical Co., Ltd.) and Red 106 (manufactured by Mikuni Sumitomo Chemical Co., Ltd.). Note that the dimensions of each sample are the same as the dimensions of the sample of Example 1.

(Example 1 and Comparative Examples 2 and 3) Example 1 and Comparative Examples 2 and 3 relate to a two-layer cleaning agent in which the amount of liquid component is increased in the central axis layer and a two-layer cleaning agent in which the outer layer is increased. It was manufactured in the same manner as in Reference Example 1 except that coconut oil fatty acid diethanolamide (Daianol CDE manufactured by Daiichi Kogyo Seiyaku Co., Ltd.) was used as the liquid component, and blended as shown in Table 3. The dimensions of each sample are the same as the dimensions of the sample of Reference Example 1.

(Reference Example 5) The raw material composition of the outer layer of Reference Example 1 in Table 1 was blended with a brown enzyme (Biolase manufactured by Nagase Sangyo Co., Ltd.) as a minor component at a ratio of 1.0% by weight of the raw material, The same composition and the same method as in Reference Example 1 were produced, and the same size was obtained.

(Physical property test method) “Hand stain due to detergent” and “Sticky of detergent” in Table 1 were judged by the degree of coloring of the pigment on the finger and the feeling of stickiness when the detergent was lightly picked with a finger. .

The color of the cleaning water by the cleaning agent in Table 2 is as follows. The cleaning water flowing in the toilet when the two-layer cleaning agent is put in the container of FIG. 4 (having holes at the top and bottom) and used on the water storage tank of the flush toilet. The color was evaluated by visual observation. When the container shown in FIG. 4 is used, the flowing water from above does not directly come into contact with the cleaning agent, enters the container through the hole at the top of the container, flows along the inner wall, flows to the bottom, and the water from the bottom hole also enters the container. As it enters, the cleaning agent will melt from the bottom surface soaked in water.

The “shape retention of the cleaning agent” in Table 3 was evaluated by the degree of deformation when the cleaning agent was lightly picked with a finger by a monitor of 10 persons.

As shown in Table 1, Reference Example 1 in which no pigment was blended in the outer layer clearly did not cause stains on the hand, whereas Comparative Example 1 in which pigment was blended in the outer layer did not stain the hands. Arise.

As shown in Table 2, from Reference Example 2 in which blue is added to the outer layer and a yellow dye is added to the central axis layer, green cleaning water is added to Reference Example 3 in which blue is added to the outer layer and red dye is added to the central axis layer. The orange wash water is obtained from the reference example 4 in which the purple wash water is mixed with red in the outer layer and the yellow dye is blended in the central axis layer. A similar colored wash water was obtained. In other words, if different dyes are blended in each layer, they will be mixed colors in the wash water at the time of use. Therefore, the two-layer detergent has a design effect by color layer separation, while at the time of use a fresh mixed color. Can be used for washing water.

表３に示すように、液体成分である椰子油脂肪酸ジエタノールアミドを中心軸層に多く配合した実施例１の保形性はよいが、それを外側層に配合した比較例３は不良となり、それを中心軸層と外側層に半分ずつ配した比較例２はやや不良となっている。このことは、従来液体成分が配合できなかった組成の原料でも、それを中心軸層に配合すれば、保形性が維持できた。また、ベトツキ感も実施例１には認められなかったが、比較例２、３には認められ、特に比較例３は著しかった。

As shown in Table 3, the shape retention of Example 1 in which a large amount of coconut oil fatty acid diethanolamide, which is a liquid component, was blended in the central axis layer was good, but Comparative Example 3 in which it was blended in the outer layer was poor, In Comparative Example 2 in which the halves are arranged in half in the central axis layer and the outer layer, they are slightly defective. This indicates that, even with a raw material having a composition that could not be blended with conventional liquid components, shape retention could be maintained by blending it into the central axis layer. Also, no stickiness was observed in Example 1, but it was recognized in Comparative Examples 2 and 3, and Comparative Example 3 was particularly remarkable.

Furthermore, in the sample of Reference Example 5 in which the brown enzyme was blended as a minor component in the raw material composition (without pigment) of Table 1, the brown enzyme was spotted in the outer layer of the two-layer detergent. Appeared on the surface, the design effect was recognized.
