BACKGROUND OF THE INVENTION
  The present invention is common in that when a cleaning agent is sprayed on an object to be cleaned using a discharge container equipped with a discharge device, a smooth discharge property can be obtained.ToIt exhibits excellent adhesion retention and dirt removal performance, and can be suitably used in kitchens and bathrooms.For mesh structures such as strainers and triangular cornersThe present invention relates to a cleaning agent and a cleaning product.
[0002]
[Prior art]
Conventionally, slime stains that appear in triangular corners of kitchens are composed of microorganisms such as bacteria, yeast, and mold, and metabolites when they decompose food, etc. For this reason, many consumers feel that they do not want to do such work by touching them with their hands or rubbing them with a sponge.
In addition, bacteria that cause food poisoning such as Staphylococcus aureus, Salmonella, Vibrio parahaemolyticus, and pathogenic Escherichia coli may be generated around the kitchen in the summer, and it is necessary to decompose and remove them.
[0003]
Therefore, in order to remove slimy stains without directly rubbing, and to decompose and remove bacteria and the like at once, bleaching agents based on alkali metal hypochlorite as a main base are frequently used.
At that time, in recent years, a method of storing a bleaching detergent in a discharge container provided with a discharge device such as a trigger type sprayer for easy use, and spraying the bleaching detergent using this discharge device is often adopted. . In this case, it is required to improve the adhesion staying property to the object to be cleaned.
[0004]
As a method for improving the adhesion retention, an attempt has been made to increase the adhesion retention by increasing the viscosity of the cleaning agent. As a composition for increasing the viscosity, a composition containing a specific cross-linked polymer (JP 06-235000 A), a composition containing sodium magnesium silicate (JP 11-217596 A), a specific interface A composition containing an activator and a hydrophobic organic counter ion (Japanese Patent Laid-Open No. 11-279591) is disclosed.
[0005]
On the other hand, a foaming cylinder (Japanese Utility Model Publication No. 6-34858) or a mesh screen (Japanese Patent Publication No. 63-2668) is provided to foam a relatively low viscosity cleaning agent. In this case, since the viscosity is low, the discharge property is good, and the cleaning agent can be attached so as to cover the surface of the cleaning object relatively uniformly. Further, since the apparent specific gravity is reduced by the bubbles, it is possible to stay in the same position to some extent without being immediately drained by its own weight after adhering to the surface of the object to be cleaned.
[0006]
[Problems to be solved by the invention]
However, in the method of increasing the viscosity of the cleaning agent, the viscosity at the time of discharge is too high, and it is difficult to obtain smooth discharge performance, and the discharge liquid is sprayed linearly in the shape of a water gun or sprayed on a spot, and the object to be cleaned There was a problem that the surface could not be covered uniformly. In addition, dripping due to its own weight occurred, and the adhesion retention was not sufficient.
On the other hand, as described above, in the method of foaming a cleaning agent having a relatively low viscosity, the viscosity must be lowered to the extent that foaming is possible. It could not be said.
[0007]
Furthermore, when the object to be cleaned is a mesh structure such as a strainer or a triangular corner, the cleaning agent passes between the meshes in both cases of thickening the cleaning agent and foaming the cleaning agent. Therefore, there is a problem that only a part of the discharged cleaning agent can be attached to the object to be cleaned.
[0008]
  In view of the above circumstances, the present invention has a smooth discharge property andIn addition,Without passing through the mesh, it adheres so as to uniformly cover the dirt on the surface of the object to be cleaned, and can exhibit excellent adhesion retention and dirt removal performance.For mesh structures such as strainers and triangular cornersIt is an object to provide a cleaning agent and a cleaning product.
[0009]
[Means for Solving the Problems]
As a result of intensive investigations to solve the above-mentioned problems, the present inventors have made thixotropic properties for the cleaning agent, so that foaming can be achieved even with a relatively high viscosity, and smooth discharge can be achieved. I found. It has also been found that the discharged cleaning agent can be prevented from passing through the mesh by roughening the size of the bubbles to some extent. Furthermore, it has been found that it is effective to add a specific water-soluble compound to the cleaning agent in order to obtain a foam having an appropriate roughness.
[0010]
  That is, the present invention is a cleaning agent comprising (1) an alkali metal hypochlorite, (2) an alkali agent, (3) a surfactant, and (4) a water-soluble compound., (3) A surfactant is a surfactant mixture containing (a) an alkali metal salt of a fatty acid, (b) an amine oxide, and (c) an alkylbenzene sulfonate, and (4) a water-soluble compound is represented by the following (A ) To (C) are water-soluble compounds or mixtures thereof.In the cleaning agent, (1) the content of alkali metal hypochlorite is 0.1 to 10% by mass, (2) the content of alkaline agent is 0.1 to 5% by mass, (3) surface activity The content of the agent is 0.1 to 10% by mass, (4) the content of the water-soluble compound is 0.05 to 5% by mass, and (a) the content of the alkali metal salt of the fatty acid is 0.01 to 3%. Mass%, (b) the content of amine oxide is 0.01 to 5 mass%, and (c) the content of alkylbenzene sulfonate is 0.01 to 0.5 mass%.A cleaning agent for a network structure is provided.

      R¹O (EO)_nR²    (I)
      (Wherein R¹, R², EO, n represent the following.
        R¹, R²: Hydrogen or a branched or straight chain alkyl group having 1 to 8 carbon atoms

      q: average added mole number of ethylene oxide, 0 ≦ q ≦ 15
      p + q = 1-15)
(C) One type or two or more types of end-capped water-soluble compounds represented by the following formula (III)
    R⁵O-[(AO)_s(EO)_t] -R⁶                (III)
    (Wherein R⁵, R⁶, AO, EO, s, t represent the following.
      R⁵: Monovalent hydrocarbon group having 1 to 8 carbon atoms which may contain a substituent

[0011]
In the general formula (III), [(AO)_s(EO)_t] Shows a state in which alkylene oxide and ethylene oxide are randomly mixed and polymerized. (B) and (C) may be the same when the number of added moles is small and cannot be clearly distinguished.
[0012]
Since the cleaning agent of the present invention has thixotropic properties, even if it has a high viscosity at the time of standing, the fluidity increases due to a high shear stress at the time of discharge, so the discharge liquid is sprayed linearly in a water gun shape, The problem that the surface of the object to be cleaned cannot be uniformly covered by being sprayed on the spots can be solved.
Further, after the discharge, when the surface of the cleaning object is reached, the shear stress disappears, so that the viscosity increases again. Furthermore, since fluidity increases due to high shear stress during ejection, it is possible to eject foam containing bubbles in the cleaning agent, so that the apparent specific gravity can be reduced. Therefore, it is possible to prevent the liquid from dripping immediately by its own weight after adhering to the surface of the object to be cleaned. That is, the high viscosity when reaching the surface of the object to be cleaned and the apparent decrease in specific gravity make it possible to ensure adhesion retention and dirt removal performance.
[0013]
  Furthermore, the cleaning agent of the present invention can be discharged in the form of foam having an appropriate roughness, and is an object to be cleaned.Of the mesh structurePassing through the mesh can be prevented. Therefore, the discharged cleaning agent can be efficiently attached to the object to be cleaned and cleaned.
    Although the reason why the cleaning agent of the present invention can be discharged into a foam having an appropriate roughness is not clear, the specific water-soluble compound enters the foam film, thereby enabling stable foam formation. It is presumed that
[0014]
Therefore, the cleaning agent of the present invention exhibits a high viscosity on the surface of the object to be cleaned and can reduce the apparent specific gravity by the foam, and forms a foam having an appropriate roughness, so that only the vertical surface and the inclined surface are formed. In addition, it exhibits excellent adhesion retention even for a network structure such as a strainer or a triangular corner, and as a result, a high effect can be obtained in removing slime, which is a main component of dirt, and sterilizing power.
[0016]
In the present invention, the viscosity of the cleaning agent measured at 25 ° C. using a Haake RS-100 viscometer is 3000 sec.^-1In the shear rate range of 0.1 to 100 mPa · s, 0.5 sec^-1In the shear rate range of 100 to 1 × 10^FivemPa · s is desirable.
Here, 3000sec^-1The viscosity in the shear rate range is 0.5 sec.^-1From 3000sec^-1Up to 3000 seconds when going up in 10 minutes^-1It is the viscosity when reaching. Similarly, 0.5 sec^-1The viscosity at the shear rate range is 3000 sec.^-1From 0.5 sec^-1On the return trip when descending in 10 minutes until 0.5 sec^-1It is the viscosity when reaching.
According to the present invention, the cleaning agent has a low viscosity at a high shear rate when spraying from a discharge device such as a trigger sprayer, and has a high viscosity at a low shear rate when adhering to a wall surface. Moreover, it is possible to achieve both dischargeability and adhesion retention.
[0017]
  The present invention also includes a discharge container having a container main body for storing the cleaning agent, a discharge device for discharging the cleaning agent stored in the container main body, and a cleaning agent including the cleaning agent stored in the container main body. The product is a cleaning product, wherein the discharge device has a foaming mechanism, and the cleaning agent is the cleaning agent according to the present invention.For mesh structuresProvide detergent products.

  According to the present invention, when the cleaning agent is sprayed on the object to be cleaned, the cleaning agent can be discharged in the form of a foam having an appropriate roughness,The object to be cleanedExcellent adhesion retention and dirt removal performance for mesh structures such as strainers and triangular corners, suitable for use in kitchens and bathroomsFor mesh structuresIt can be a detergent product.
[0019]
In this invention, the structure which has a foaming cylinder provided on the flight path | route of the cleaning agent as said foaming mechanism can be employ | adopted suitably. In addition, it is desirable that the foam-forming cylinder is arranged so as to have a central axis that is substantially the same as the central axis in the flight direction of the cleaning agent. In this case, since the cleaning agent entrains air inside the foaming cylinder while colliding with the inner wall of the foaming cylinder, the foam can be effectively contained.
When providing a foam-forming cylinder, it is desirable that the minimum inner wall diameter be 2 to 8 mm. This is because if the minimum diameter is larger than 8 mm, the cleaning agent does not easily collide with the inner wall of the foam-forming cylinder, and the cleaning agent cannot contain sufficient bubbles. On the other hand, if the minimum diameter is less than 2 mm, it is difficult to produce, and clogging is likely to occur, and the pattern does not spread in an appropriate pattern.
Moreover, when providing a bubble making cylinder, you may form an uneven | corrugated surface part in the inner wall surface. Thereby, a bubble can be included more effectively.
[0020]
In the present invention, a configuration having a mesh screen provided on the cleaning agent flight path can also be suitably employed as the foaming mechanism. It is desirable that the screen is disposed substantially orthogonal to the central axis of the cleaning agent in the flight direction.
In this case, the cleaning agent that flies may be configured not to come into contact with surrounding members until reaching the screen, but the configuration in which the screen and the foam cylinder are combined, in particular, near the outlet of the foam cylinder. It is desirable to have a configuration provided in In this case, since the cleaning agent entrains air inside the foaming tube while colliding with the inner wall of the foaming tube, and further entrains air on the screen surface even when passing through the screen, it can contain bubbles more effectively.

The ratio of the unsaturated fatty acid salt is preferably 2% by mass or more, particularly 7% by mass or more in the component (a).
  If the ratio of the unsaturated fatty acid is too small, the viscosity of the system is lowered, and as a result, the adhesion retention is deteriorated.
[0026]
Although content in particular of (a) component in the cleaning agent of this embodiment is not restrict | limited, Preferably it is 0.01-3 mass% of the whole composition, More preferably, it is the range of 0.1-2 mass%.

[0030]
Examples of the surfactant other than the components (a) to (c) include α-olefin sulfonic acid, polyoxyethylene alkyl ether sulfate, polyoxyethylene alkyl ether, and the like.
When these surfactants are dispersed in a high electrolyte solution mainly composed of alkali metal hypochlorite, stringent micelles are entangled in a stationary state or a low shear rate region, and the viscosity is increased. In the high shear rate region discharged from the discharge container nozzle, it is considered that the entanglement with respect to the flow can be removed or the viscosity is extremely decreased because the string micelles are arranged in parallel. In addition, it is considered that the random entanglement is formed again when returning to the stationary state, and the thixotropy of the semi-viscous flow in which the viscosity becomes high again is exhibited.

This is not preferable because it is difficult to lift up.
[0034]
The total content of the surfactant (3) in the cleaning agent of the present embodiment is not particularly limited, but is preferably 0.1 to 10% by mass, more preferably 0.5 to 5% by mass of the entire composition. % Range. (3) When the content of the component is less than 0.1% by mass, the adhesion retention in the network structure such as the wall surface deteriorates, and when it exceeds 10% by mass, the viscosity of the composition becomes too high, and the trigger sprayer When a discharge device such as the above is used, it is difficult to spray the composition and it is difficult to continuously pump the composition from the dip tube.

[0043]
The water-soluble compounds (B) and (C) must be end-capped. This is because the water-soluble compounds (B) and (C) are relatively low molecules, and if the terminal is unblocked, decomposition occurs due to the alkali metal hypochlorite of the component (1), which is good. This is because the effect of imparting adhesion retention cannot be maintained.
[0044]
The content of the water-soluble compound (4) in the cleaning agent of this embodiment is usually 0.05% to 5% by mass, preferably 0.1% to 3% by mass.
When the amount of the water-soluble compound (4) is too small, coarse bubbles are not formed in the viscous inner solution, and as a result, adhesion to a structure having a network structure cannot be obtained. On the other hand, when the amount is too large, decomposition of the alkali metal hypochlorite which is a bleaching substrate is accelerated, which is not preferable.
The water-soluble compound (4) is used singly or in combination of two or more.
[0045]
  By containing these water-soluble compounds, coarse bubbles are formed in the discharge, and as a result, the object to be cleanedOf the mesh structureIt can adhere efficiently without passing through a mesh.
[0046]
The cleaning agent of the present embodiment has the above components (1) to (4) as essential components, but as other builder for improving cleaning performance, aromatic sulfonates such as toluene sulfonate and xylene sulfonate, It is also possible to mix arbitrary components such as a solvent, a pigment, and a fragrance. The blending amount of these optional components can be a normal amount as long as the effects of the present invention are not hindered. Moreover, the cleaning agent of this embodiment can be adjusted by a conventional method by adding a balanced amount of water to the above essential components and other optional components.
[0047]
Next, the cleaning product according to this embodiment will be described. The cleaning product according to the present embodiment is a product in which the cleaning agent according to the present embodiment is filled in a discharge container including a discharge device. In the present embodiment, a case will be described in which a trigger type discharge container using a trigger pump as a discharge device is filled with a cleaning agent to obtain a cleaning product.
FIG. 1 is a schematic configuration diagram showing a cleaning product according to an embodiment of the present invention. The cleaning product of this embodiment includes a discharge container 1 and a cleaning agent 70. The discharge container 1 has a neck portion 13a, a container body 13 filled with the cleaning agent 70, and an upper portion of the neck portion 13a. It is comprised from the trigger pump 20 (discharge device) attached to. The cleaning agent 70 is the cleaning agent of the present embodiment described above.
[0048]
The trigger pump 20 is attached to the injection cylinder 14, the trigger lever 11, the cap 16, the dip tube 17 inserted into the container body 13 and connected to the upstream side of the injection cylinder 14, and the distal end side of the injection cylinder 14. The injection nozzle 15 is connected to the downstream side of the injection cylinder 14, and the injection nozzle 15 is provided with a foaming mechanism.
Although a detailed description and illustration inside the injection cylinder 14 are omitted, a piston portion 12 that is operated by a trigger lever 11 is incorporated, and an intake valve on the upstream side of the piston portion 12 and an injection valve on the downstream side are provided. . Then, by operating this piston portion 12, the cleaning agent 70 introduced from the dip tube 17 is fed to the injection nozzle 15 at a high pressure.
In addition, although there is no limitation in particular in the material of each member, it is preferable that the trigger lever 11, the cap 16, the injection nozzle 15, and the container main body 13 are made of polypropylene. Moreover, it is preferable that a piston part incorporates the spring which consists of SUS316, and is formed with a soft polyethylene. In addition, the intake valve and the ejection valve can be configured using a soft polyethylene valve, a polyethylene ball, or the like.
The dip tube 17 is made of soft polyethylene or the like and is fixed inside the cap 16 via an intake (not shown) made of polypropylene or the like. The cap 16 is a packing (not shown) made of foamed polyethylene or the like. The container body 13 is screwed in a watertight manner.
[0049]
A foaming mechanism for causing the cleaning agent 70 to contain foam is provided in the spray nozzle 15. In the injection nozzle 15, either a bubble mode or a closed mode can be selected. When the foam mode is selected, bubbles are generated in the cleaning agent 70 by the foam-forming mechanism (the foam-forming cylinder 39 and the screen 42) in the injection nozzle 15, and the cleaning agent 70 containing the bubbles is injected. The liquid is sprayed toward the object to be cleaned.
Hereinafter, the configuration and operation of the injection nozzle 15 will be described in detail for each mode.
[0050]
FIG. 2 is a longitudinal sectional view showing the injection nozzle 15 in the bubble mode.
In FIG. 2, reference numeral 31 denotes a cleaning agent guide body fitted and fixed inside the end portion 12 b on the downstream side of the piston portion 12 at the tip end portion of the injection cylinder 14. The distal end portion of the cleaning agent guide body 31 is a plug body 32 in which shallow grooves 60 and 60 are formed in the busbar direction at a plurality of circumferential positions.
[0051]
Reference numeral 28 denotes a nozzle body, which is rotatably fitted to the end 12b of the piston portion 12 in a substantially cylindrical fitting wall 25. A shielding wall 26 is formed on the downstream end face of the fitting wall 25, and a nozzle hole 27 is formed in the center in the vicinity of the distal end portion of the plug 32. A gap between the nozzle hole 27 and the plug 32 is a spin region 63.
Further, the nozzle body 28 is formed with an inner cylinder portion 33 from the shielding wall 26 toward the upstream side, and the protruding end portion 61 of the inner cylinder portion 33 has inner grooves 24 in a plurality of circumferential directions in the direction of the bus. , 24 are formed. In the case of the bubble mode of FIG. 2, the positions of the inner grooves 24, 24 and the shallow grooves 60, 60 coincide with each other in the circumferential direction, and the inner cylinder portion 33 and the cleaning agent guide body formed by connecting these grooves. A space between the piston portion 31 and the spin region 63 forms a flow path 62 that leads from the piston portion 12 to the nozzle hole 27.
[0052]
Further, the peripheral wall 50 of the nozzle body 28 has a protruding wall 51 on the downstream side, and a mounting cylinder 41 integrally formed with the screen 42 and the foam-forming cylinder 39 is fitted and fixed to the protruding wall 51. . The foam-forming cylinder 39 is arranged coaxially with the mounting cylinder 41 with the downstream end face aligned. Further, the foam-forming cylinder 39 is formed to have a smaller diameter and shorter than the mounting cylinder 41, and a gap 34 is formed between the foam-forming cylinder 39 and the shielding wall 26. Further, the screen 42 is positioned on the downstream end face of the foam-forming cylinder 39 and the mounting cylinder 41, and the position of the foam-forming cylinder 39 with respect to the mounting cylinder 41 is maintained by the screen 42.
A liquid dripping prevention mechanism 80 is formed on the downstream side of the shielding wall 26 so as to protrude toward the foam-forming cylinder 39.
The inner wall 40 of the foam-forming tube 39 is formed in a flat cylindrical shape. However, when it is necessary to further promote the formation of bubbles, ring-shaped protrusions may be formed in various patterns. The screen 42 is formed with a plurality of mesh holes 43 in various patterns.
A path from the mesh holes 43 to the gap 34 via the bubble-forming cylinder 39 and the mounting cylinder 41 is an air introduction path 52 into the bubble-forming cylinder 39.
[0053]
As described above, in the foam mode shown in FIG. 2, the positions of the inner grooves 24, 24 and the shallow grooves 60, 60 coincide with each other in the circumferential direction, and the inner cylinder portion 33 formed by communicating these grooves and the cleaning agent. A gap between the guide body 31 and the spin region 63 forms a flow path 62 that leads from the piston portion 12 to the nozzle hole 27. In this case, the flow path 62 is narrow at the position of the shallow grooves 60, 60 and has a sharp bend at the position where the spin region 63 is entered.
Therefore, when the cleaning agent 70 whose pressure has been increased by the piston portion 12 is supplied, the high-pressure cleaning agent 70 rapidly flows from the periphery of the spin region 63 toward the center and is rotated at a high speed.
Then, it is ejected from the nozzle hole 27 in a conical flow shape, and reaches the screen 42 without colliding with the inner wall 40 of the foam-forming cylinder 39. Further, while colliding with the screen 42, the mesh hole of the injection port 39a. 43 and 43 are discharged as the injection liquid F.
[0054]
In this way, in the process in which the cleaning agent 70 passes through the nozzle hole 27 via the flow path 62, the viscosity decreases due to shearing stress from each member of the nozzle 15, so that the injection is performed without requiring a strong gripping force of the user. it can. In addition, the nozzles 27 are uniformly ejected without causing spots like when a high viscosity cleaning agent is forcibly discharged. On the other hand, since the moderate viscosity is maintained, the air G can be appropriately taken in as fine bubbles in the process of colliding with the inner wall 40 and the screen 42 of the foam-forming cylinder 39.
[0055]
Then, when the spray liquid F reaches the object to be cleaned, the shear stress suddenly decreases and the high viscosity is immediately recovered. In this way, the high viscosity is recovered, and the apparent specific gravity is lowered due to the taken-in bubbles, so that the jet liquid F has high adhesion retention. Moreover, since it inject | emitted uniformly from the nozzle hole 27, it can adhere to a washing | cleaning target object also uniformly.
[0056]
FIG. 3 is a longitudinal sectional view showing the injection nozzle 15 in the closed mode.
3, the same components as those in FIG. 2 are denoted by the same reference numerals, and detailed description thereof is omitted. Switching from the foam mode shown in FIG. 2 to the closed mode shown in FIG. 3 is performed by rotating the nozzle body 28 by 120 degrees. However, for convenience of explanation, in FIG. It shows the state rotated by a degree.
[0057]
In the closed mode of FIG. 3, a portion where the shallow groove 60 of the plug body 32 is not formed is located in the circumferential direction to be communicated with the inner grooves 24, 24. The hole 27 is blocked without reaching.
Therefore, even when the cleaning agent 70 whose pressure has been increased by the piston portion 12 is supplied, the cleaning agent 70 is not ejected from the nozzle 15.
[0058]
In the present embodiment, the foam-forming cylinder 39 and the like are formed separately from the nozzle body 28, but may be formed integrally with the nozzle body 28. For example, it may be formed continuously with the inner cylinder portion 33 while securing the air introduction path 52.
In this embodiment, a trigger type discharge container using a trigger pump is filled with a cleaning agent to obtain a cleaning product, but a former pump dispenser can also be used.
[0059]
FIG. 4 is a photograph showing a state about 10 seconds after the cleaner of the present embodiment is sprayed on the strainer by the cleaner product of the present embodiment. As shown in FIG. 4, it is possible to attach the coarse foam B of the cleaning agent so as to cover the periphery without passing through the mesh M of the peripheral wall of the strainer W, and to retain it thereafter. Therefore, according to the present embodiment, it is possible to exhibit excellent dirt removal performance with respect to an object to be cleaned having a mesh structure such as a strainer.
