Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slow-solubilizing agent that adjusts the speed of a cleaning agent and an aromatic agent to be eluted in the stored water by, for example, being put into a water tank of a flush toilet, and an aromatic cleaning agent using the same. It is about.

[0002]

2. Description of the Related Art So far, various solid aroma cleaners have been developed as aroma cleaners that are gradually poured into a water storage tank of a flush toilet to elute the cleaning agent and the fragrance. Such a fragrance cleaner sinks to the inner bottom of the water tank when it is put into the water tank, and at least adheres to the inner bottom of the water tank so that it does not flow due to the water flow when the water is supplied and drained. In addition to eluting the fragrance and the fragrance, it is necessary to prevent the formation of suspended solids or precipitates during the elution of these compositions, and it is necessary to devise the selection of blending ingredients and blending ratio (composition) to satisfy such performance. It has been broken.

Specifically, the fragrance detergent is a compounding ingredient which is a detergent that causes the stored water to have a predetermined cleaning function by being eluted into the stored water, an fragrance that causes an aroma by being eluted into the stored water, and the cleaning agent. Excipients for adjusting the moldability of blends of fragrances and fragrances to facilitate solidification, slow-dissolving agents for adjusting the elution rate of the detergents and fragrances, and solids produced as necessary A specific gravity adjusting agent for increasing the specific gravity of the above than water, a water-soluble dye for making the elution of the components visible, and the like are used.

The materials used for the above solid agents are:
Examples include fragrances, surfactants, dyes, bactericides, deodorants, bleaches and the like.

Further, in the product, if necessary, for example,
Proteolytic enzymes such as protease for degrading protein stains, sodium gluconate for sequestering metal ions, E
A chelating agent component such as DTA or NTA, an antifoaming agent such as silicone for eliminating foaming at the time of preparation, and a chlorine-based detergent component such as calcium hypochlorite or chlorinated isocyanuric acid can be added and blended, In addition, known pH adjusters, buffers,
Additives such as a disinfectant, a germicide, a dechlorinating agent, a bleaching agent, and a specific gravity adjusting agent can be added.

The above-mentioned specific gravity adjusting agent is for adjusting the specific gravity of the product. As the specific gravity adjusting agent, there are water-soluble inorganic compounds having a true specific gravity of 1.50 or more, such as sodium sulfate, calcium sulfate and sodium thiosulfate. sodium carbonate,
Sodium hydrogen carbonate, sodium silicate, sulfamic acid and the like can be advantageously used.

The blending amount can be appropriately determined according to the intended specific gravity, but it is usually appropriate to be 5 to 50%.

As the fragrance, various kinds used as fragrances can be used alone or in combination of two or more kinds. Specific examples thereof include natural plant essential oils such as lavender, lemon oil, rose oil, spearmint oil, green oil, etc., animal flavors such as musk, cypet, etc., synthetic flavors such as aldehydes, ketones, esters, and the like. Examples thereof include a mixture and the like.

The blending amount of the above-mentioned fragrance into the solid agent is slightly different depending on the kind of fragrance, the strength of the fragrance, the size of the product to be obtained, etc., but is usually in the range of about 0.1 to 50 wt% in the product. It is preferable that the amount is contained in. If the amount of the above-mentioned fragrance is too small, the fragrance becomes weak and the fragrance does not last long. Further, if it is blended in an excessively large amount, it becomes difficult to solidify the composition at room temperature, the robustness of the composition itself is deteriorated, and the composition is easily eluted by running water. A particularly preferable amount of fragrance is about 1 to 20 wt%.

The pigment is used as a measure of the effectiveness of the solid drug itself. As the pigment, water-soluble dyes such as methylene blue, cyanine blue, blue No. 1, yellow No. 4,
Yellow No. 5, Yellow No. 202, Red No. 106, Green No. 3, Blue No. 202, Blue No. 203, etc. can be advantageously used. The blending ratio can be appropriately determined according to the type (color tone, concentration) of the dye, but normally it is appropriate to be about 0.5 to 20 wt%. If this is less than the above range, the color of the eluate may be light or may not be colored, and a refreshing feeling, a feeling of hygiene, etc. may not be expressed, and if it exceeds the above range, the coloration is too dark and rather unpleasant. May be given. The dye may not be used depending on the use situation.

The surfactant or soap mainly contributes to the cleaning agent, and also affects the slow solubility of the pigment and the fragrance and the fastness of the composition. Especially for the fragrance, it is possible to simultaneously elute it with running water, resulting in an attempt to expand the volatilization area of the fragrance. As the above-mentioned surfactant, various widely known ones can be used. As typical examples thereof, for example, polyoxyethylene lauryl ether, polyoxyethylene cetyl ether, polyoxyethylene oleyl ether, polyoxyethylene nonylphenol ether, polyoxyethylene sorbitan tristearate,
Examples include polyoxyethylene sorbitan monostearate, polyethylene glycol monostearate, polyoxyethylene distearate, polyoxyethylene polyoxypropylene block polymer, fatty acid glyceride, fatty acid alkanolamide, sodium alkylbenzene sulfonate, and alkylbenzene sulfone. Examples thereof include anionic surfactants such as magnesium acid salt and sodium alkylsulfate. These may be used alone or in combination of two or more. Among them, polyoxyethylene distearate, polyoxyethylene lauryl ether, polyoxyethylene nonylphenol ether and the like are particularly preferable.

The above surfactant is about 50 to 95 wt%,
It is preferably blended in the range of about 60 to 90 wt% to achieve a desired effect. If this content is less than 50 wt%, the foamability is poor, the cleaning effect cannot be expected, and it becomes difficult to gradually dissolve the dye, which may lead to deterioration in the fastness of the composition. If it exceeds 95% by weight, the content of other components, especially the fragrance, will inevitably decrease, and the expression of aromaticity due to this will decrease.

Then, for example, polyethylene glycol distearate, beef fatty acid monoglyceride, POE
It is known to use (polyoxyethylene) nonylphenyl ether, sodium sulfate calcium sulfate, Blue No. 1 and a mixed fragrance. The following Table 1 shows the blending ratio of the aroma cleaning agent according to the above blending components.

[0014]

[Table 1]

[0015]

By the way, in the production of such a fragrance cleaner, in order to make it more valuable as a competitor's competitive product, the basic performance such as cleaning performance and fragrance is Of course, it is important to extend the duration of effect and to improve economic efficiency (reduction of product prices), as well as to improve the price.

In order to extend the above-mentioned duration of effect and improve the economical efficiency, it is necessary to optimize the compounding ingredients and the compounding ratio so that a cheaper material can exhibit the required performance. It is necessary to devise the composition of each component such as the slow-solubilizing material so that the elution of the components into the stored water can be minimized.

From such a viewpoint, as a result of analyzing the conventional aroma cleaners shown in Table 1 by the inventor of the present application, the aroma cleaners of Table 1 have a duration of efficacy of about 60 days with a preparation of 130 g,
Although it is a relatively long period of time, the elution rate of POE nonylphenyl ether, a surfactant when used as a detergent, is higher than necessary, and the duration of efficacy is improved by devising the formulation of a slow-solubilizing agent. At the same time, it was surmised that there was still room for improving economic efficiency.

Here, in order to delay the elution rate, it is conceivable to simply increase the blending ratio of the slow-solubilizing agent, but increase the polyethylene glycol distearate used in Table 1. As a result, there is some extension of the duration, but it cannot be extended many times.
Further, the balance of the formulation components is lost, and in particular, the performance of the in-tank formulation itself cannot be exhibited, so that the blending ratio cannot be simply increased.

Further, the conventional ones have a problem that the elution rate depends on the water temperature of the stored water, and the duration of potency is shortened in summer when the water temperature becomes higher than in winter.

Therefore, an object of the present invention is to solve the above-mentioned problems, and by adding another component as a slow-solubilizing agent, the water temperature dependence of the elution rate can be reduced and the duration of efficacy due to fluctuations in water temperature can be reduced. It is intended to provide a fragrance cleaner which can prevent the increase and decrease of the amount of the fragrance, and can significantly extend the duration of the effect by using the above-mentioned slow-solubilizing agent and at the same time improve the economical efficiency.

Further, the above-mentioned hydroxypropylmethyl cellulose and its analogs are blended in an amount of 1 to 50 wt% of the total weight.

According to the above configuration of the present invention, the water temperature dependence of the elution rate is reduced, and it is possible to prevent the occurrence of the inconvenience that the duration of the effect is increased or decreased due to the fluctuation of the water temperature due to the change of the season or the like. .

Further, while maintaining the required detergency, the elution rate of the detergent can be delayed to extend the duration of the effect, and the compounding ratio of the newly added hydroxypropylmethylcellulose can be increased to 1 to 50% by weight. If so, the duration of efficacy can be significantly extended to about 90 days with 100 g of formulation.

Moreover, the newly added hydroxypropylmethyl cellulose has the same raw material cost as the conventional slow-solubilizing agent (polyethylene glycol distearate), and the manufacturing cost as an aroma cleaner is the same as that of the conventional product. It can be suppressed and the duration of the effect can be extended, so that the economy from the consumer side can be improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows an embodiment of an aroma cleaner according to the present invention. This fragrance cleaner 1
Is to gradually elute the cleaning agent and the fragrance into the water storage 3 by being put into the water storage tank 2 of the flush toilet. Table 2 shows the compounding ingredients and the compounding ratio.

[0031]

Is melted by heating at 55 to 77 ° C. and then made into a slurry. Then, after adding Blue No. 1 and blended fragrance to the slurry-like mixture and uniformly kneading, the mixture was poured into a rectangular parallelepiped mold, cooled and solidified, then taken out from the mold and cut into an appropriate size to give an aroma. The cleaning agent 1 is obtained.

For comparison, Table 2 also shows the compounding ratio of the conventional fragrance cleaner.

Parts and 5 parts of the mixed fragrance are uniformly mixed, poured into a rectangular parallelepiped extrusion mold at 60 to 80 ° C., cooled and solidified, taken out of the mold, and cut into an appropriate size to obtain an aroma cleaner 1. May be.

In order to improve the performance of the above fragrance cleaner, the weight, the duration of efficacy, the specific gravity, the adhesion to the inner bottom of the water storage tank 2 and the water temperature dependence of the elution rate were measured in comparison with conventional products. Table 3 below shows the measurement results.

[0036]

[Table 3]

Among the measurement items shown in Table 3, the duration of efficacy is measured by flushing data. Here, the flushing data is data by an automatic water supply system that fills the container with 3 liters of water at 1-hour intervals. The water temperature dependence of the elution rate is as follows: put the sample in a water tank with water temperature of 5 ° C, 25 ° C, 40 ° C,
It was measured by observing the progress of elution.

Adhesiveness means that the formulation is put into a low tank, and after the formulation is adhered (after 3 to 6 minutes), the formulation is pulled by a wire attached to a spring and the formulation adhered to the bottom of the tank is moved from the tank. It shows the maximum value of force. Adhesiveness includes the force required to move the formulation in close contact with the tank bottom in the horizontal direction with the tank bottom (horizontal adhesion) and the force required to move the formulation in close contact with the tank bottom in the direction orthogonal to the tank bottom ( Vertical adhesion).

The measurement items shown in Table 3 show the vertical adhesion, but in consideration of the water circulation in the tank into which the preparation is put, a larger force is applied to the preparation in the horizontal direction than in the vertical direction. . Therefore, the horizontal adhesion is more important for the adhesion of the preparation.

A method of measuring horizontal adhesion will be described below with reference to FIG. As shown in FIG. 2, the container 11
Is filled with tap water, and the low tank material 15 on which the dew-proof layer 13 is laminated is fixed to the bottom of the container 11. Then, a wire to which one end of the octopus thread 17 is tied is attached to the preparation 19, and then the preparation 19 is gently placed on the dew-preventing layer 13, and then the other end of the octopus thread 17 is fixed to the gauge 21.

When the horizontal adhesion is measured, the other end of the tacho thread 17 is pulled by the pulley 2 in order to apply a horizontal force to the preparation 19.
It is fixed to the gauge 21 through 3. In addition, when measuring the vertical adhesion, the other end of the tacho thread 17 does not use the pulley 23 to apply a force in the vertical direction to the preparation 19 and the gauge 21 is used.
Fixed to. Gauge 21 after the contact indication time has elapsed
Is pulled up vertically at a constant speed, and the gauge reading when the preparation 19 starts to move in the vertical direction is measured by the vertical adhesion force and the preparation 19
The horizontal reading is the gauge reading when starts to move horizontally.

The water temperature at the time of measurement was 26 to 27 ° C., the time from the introduction of the preparation to the placement in the dew-proof layer was about 3 seconds, and the gauge used was a push-pull gauge manufactured by Imada Co., Ltd.

Table 4 shows the results of measuring the horizontal adhesion of the preparations A to D containing the slow-dissolving agent of the present invention and the preparations E to H not containing the slow-dissolving agent as comparative examples by the above measuring method. . Formulations A to D and Formulations E to H were prepared with the components of the examples and conventional products shown in Table 2, respectively, and the measurement results at weights of 130, 90, 65 and 45 g, respectively. Is shown.

[0044]

[Table 4]

As shown in Table 4, each of the preparations A to D containing the slow-dissolving agent of the present invention exceeded the average value of 150 (gf), which is the allowable value of adhesion, and showed good adhesion. It was confirmed.

As described above, according to the fragrance cleaner 1 of the present invention, the water temperature dependence of the elution rate is reduced, and the inconvenience of the effect is increased or decreased due to the fluctuation of the water temperature due to seasonal changes or the like. Can be prevented.

Further, while maintaining the necessary detergency, the elution rate of the detergent can be delayed to extend the duration of efficacy, and the duration of efficacy can be greatly expanded to about 90 days. it can. It is considered that the variation in the measured lifetime is due to the slightly remaining water temperature dependency, the homogeneity of the aroma cleaner 1, and the like.

Moreover, the newly added hydroxypropylmethyl cellulose has a raw material cost equivalent to that of the conventional slow-solubilizing agent (polyethylene glycol distearate), and the running cost as an aroma cleaner is less than half that of conventional products. It is possible to improve the economic efficiency from the consumer side by the extent that the effect duration is extended.

The inventor of the present invention carried out the same measurement for each measurement item shown in Table 3 by changing the compounding ratio of hydroxypropylmethyl cellulose newly added as a slow-solubilizing agent. As a result, when the compounding ratio of hydroxypropylmethyl cellulose was less than 1 wt%, the delay effect on the dissolution rate was poor, and no remarkable improvement in the duration was observed. Further, when the compounding ratio of hydroxypropylmethyl cellulose exceeds 50 wt%, the effect of delaying the elution rate becomes too strong, and the elution rate tends to be below the required amount, and the detergency tends to decrease. Further, the compounding ratio of hydroxypropylmethyl cellulose is 10 to 2
When it was 0 wt%, the duration of efficacy was extended to 80 to 90 days while ensuring the necessary and sufficient detergency. Therefore, it is appropriate to set the compounding ratio of hydroxypropylmethyl cellulose in the range of 1 to 50 wt%.

Further, the change in properties was measured by variously changing the compounding ratio of the water-soluble dye and the fragrance. As a result, when the water-soluble dye is less than 2 wt%, the coloring is too light, and
If it exceeds wt%, the coloring becomes too dark, so 2-8
It is appropriate to set it in the range of wt%.

If the blending ratio of the fragrance exceeds 20 wt%, it will be difficult to solidify the kneaded product, and the fragrance will exude due to a decrease in stability over time and the duration of the fragrance will be shortened. Must be:

EFFECTS OF THE INVENTION According to the fragrance cleaner of the present invention, the dependence of the elution rate on water temperature is reduced, and it is possible to prevent the occurrence of inconvenience such that the duration of potency is increased or decreased due to fluctuations in water temperature due to seasonal changes or the like. be able to. In addition, while ensuring the required detergency, the elution rate of the detergent can be delayed to extend the duration of the effect, and the compounding ratio of the newly added hydroxypropylmethylcellulose is 1 to 50% by weight.
The duration of potency can be greatly extended to 70-90 days.

Furthermore, it is possible to improve the horizontal adhesiveness at the bottom of the tank, which is required when the formulation is added.
In addition, the newly added hydroxypropylmethyl cellulose has the same raw material cost as the conventional slow-solubilizing agent (polyethylene glycol distearate), and the running cost as an aroma cleaner should be less than half that of conventional products. And, as the duration of effect is extended, the economy from the consumer's side can be improved.
