Description

  The present invention relates to a foam for washing, a method for producing the foam, and a method for washing hair.

  In general, when using detergents such as shampoos, hand soaps, body soaps, etc. used on the body such as the hair and skin, do not use them in liquid form. By foaming in the shape of a foam, or by foaming using a foaming mechanism-equipped container or foaming device, and washing the hair, hands and skin with the foam-like cleaning agent (foaming detergent) Appropriate cleaning power is demonstrated.

  When a liquid cleaning agent is used, it is necessary to foam the cleaning agent before starting the cleaning process, and this process is troublesome. There is also a problem that a predetermined cleaning effect cannot be expected because the method of foaming is not uniform among individuals. However, by adopting a configuration in which the foam cleaning agent previously foamed in a container with a foaming mechanism is taken out from the container, the user can immediately use the foam cleaning agent, improving usability and cleaning. Uniformity can be achieved.

  Conventionally, as a method for producing a foam detergent from a stock detergent, a foam production method using a pump former, an aerosol foam production method, an electric foam production method, and the like are known. The foam generation method using a pump former is a method in which a liquid cleaning agent is used as a foam cleaning agent using a dispenser provided with a foam generating part such as a mesh member (Patent Documents 1 and 2).

  Further, in the foam generation method using an aerosol container, when the liquefied gas serving as the propellant is discharged from the nozzle simultaneously with the cleaning liquid, the cleaning liquid foams due to the rapid expansion of the liquefied gas, thereby generating a foam cleaning agent. (Patent Document 3). Moreover, the foam generation method by electric drive arranges the foam stone (porous material) comprised so that air may be supplied from a pump in the cleaning liquid in the tank filled with the cleaning liquid, and is injected from the foam stone. This is a method in which a fine cleaning agent is produced by mixing fine air into the cleaning agent using bubbles (Patent Document 4). There is also a technique that combines a foam generation method using a pump former and an electric foam generation method that have been put to practical use in public toilets (Patent Document 5).

  However, the foam production method using the pump former has a problem that the foamed detergent produced is rough and cannot produce the desired creamy foam. In such rough textured bubbles, the contained air (bubbles) is large, and bubbles are easily broken during cleaning. Therefore, the persistence of the bubbles is poor, and there is a problem with satisfaction regarding cleaning. In addition, in the foam generation method using a pump former, the mesh member provided in the dispenser is clogged over time due to the residual / drying of the cleaning agent stock solution, and there are restrictions on the types of cleaning agent used, and depending on the usage method. There was also a problem that the service life was short. Although it is conceivable to replace the mesh member, since the mesh member is usually disposed in the back of the dispenser, the operation of replacing this is troublesome and not practical.

  Moreover, in the foam generation method using an aerosol container, a liquefied gas is required as a propellant, and since this liquefied gas is generally flammable, there is a problem in safety.

  Furthermore, in the conventional electric foam generating method, since the foam cleaning agent generated by the bubbles injected from the foam stone is not discharged to the outside until the tank is filled, it takes a long time until the foam cleaning agent can be taken out. There was a problem that it took. Moreover, the foam detergent produced | generated using a foam stone has the problem that it is rough and cannot produce desired creamy foam.

  The combined foam generation method using the pump former and the electric foam generation method is expected to reduce clogging of the mesh member, but the foam cleaning agent is rough and the desired creamy foam cannot be obtained. Will not continue to solve. In addition, there is a problem that the equipment becomes large-scale.

  The present invention has been made in view of the above points, and a first object thereof is to provide a fine and creamy foam for cleaning.

  Another object of the present invention is to provide a cleaning foam capable of efficiently and safely producing a fine-grained and creamy cleaning foam by using a detergent composition having an unprecedented amount of surfactant. It is in providing the production | generation method.

  Next, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 shows a foam generating apparatus 1 used for generating a cleaning foam A according to an embodiment of the present invention. Before describing the characteristics of the cleaning foam A, a generation method for generating the cleaning foam A, which is an embodiment of the present invention, and a foam generation apparatus 1 used when performing this generation method will be described.

  FIG. 1 is an external view of the foam generating device 1, and FIG. 2 is a cross-sectional view showing the configuration of the foam generating device 1. In the present embodiment, the foam generating apparatus 1 using a shampoo as the detergent composition stock solution B will be described as an example. However, the detergent composition stock solution B is not limited to a shampoo, such as hand soap, body soap, etc. It can be applied to various detergent composition stock solutions suitable for use as foams.

  As shown in FIG. 1, the foam generating device 1 has a hand insertion portion 3 formed on the front side of the main body portion 2. An operation unit 4 is provided inside the hand insertion unit 3, and the user of the foam generating device 1 inserts a hand into the hand insertion unit 3 and operates the operation unit 4, as described later. The cleaning foam A protrudes from the outlet 16. Further, a lid 6 is provided on the top plate of the main body 2, and the lid 6 is opened when the detergent composition stock solution B is loaded into the stock solution tank 5 in the main body 2.

  Next, the internal structure of the foam production | generation apparatus 1 is demonstrated using FIG. Inside the foam generating apparatus 1, there are a stock solution tank 5, a motor 7, a foaming chamber 8, a screw 9, an opening / closing valve 10 and the like. As described with reference to FIG. 1, the operation unit 4 is disposed in the manual insertion unit 3, but in FIG. 2, for convenience of illustration, the operation unit 4 is illustrated so as to be positioned above the main body unit 2. Yes.

  The operation unit 4 is operated by the user of the foam generating device 1 as described above. The operating unit 4 is provided with two shafts 12 and 17. The shaft 12 constitutes a part of an on-off valve 10 described later, and is attached to the main body 2 so as to be movable in the vertical direction (Z1, Z2 direction).

  The stock solution tank 5 is filled with a liquid detergent stock solution (cleaner composition stock solution B). When the amount of the cleaning composition stock solution B in the stock solution tank 5 is reduced, the lid 6 provided in the main body 2 is opened, and the stock solution tank 5 is filled with the cleaning composition stock solution B from here. . Thus, since the foam production | generation apparatus 1 can replenish the detergent composition stock solution B, compared with what discards by one use like the conventional aerosol container, it can aim at the improvement of an environmental measure, and cost reduction. it can.

  The motor 7 is configured to be driven and stopped by an ON / OFF operation of the switch 15. The switch 15 is connected to a shaft 17 disposed in the operation unit 4 and performs an ON / OFF operation by pressing operation of the operation unit 4 (operation in the Z1 direction).

  The rotation shaft of the motor 7 protrudes into the foaming chamber 8. The rotating shaft of the motor 7 penetrates through the wall portion of the foaming chamber 8 and protrudes into the inside, but the penetrating portion is sealed and has a liquid-tight configuration. A screw 9 is disposed at a portion of the rotating shaft of the motor 7 protruding into the foaming chamber 8. Therefore, the screw 9 is rotated by the motor 7.

  The foaming chamber 8 communicates with the stock solution tank 5. An open / close valve 10 is provided at the communication portion 18 between the stock solution tank 5 and the foaming chamber 8. The valve body 13 of the opening / closing valve 10 is configured to be able to open / close the communicating portion 18 between the stock solution tank 5 and the foaming chamber 8. When the valve body 13 is opened, the detergent composition stock solution B flows from the stock solution tank 5 into the foaming chamber 8, and when the valve body 13 is closed, the foaming chamber 8 is fed from the stock solution tank 5. The entrance of the detergent composition stock solution B into the inside is stopped.

  The valve body 13 is disposed at the lower end portion of the shaft 12 described above. A coil spring 11 is disposed on the shaft 12, and the coil spring 11 always urges the shaft 12 in a direction in which the valve body 13 closes the communication portion 18 (Z2 direction).

  Furthermore, an air suction port 14 is provided at the upper part of the end of the foaming chamber 8 in the direction of the arrow X2. When the screw 9 rotates, air flows into the foaming chamber 8 from the air suction port 14.

  When the operation unit 4 is pressed in the foam generating apparatus 1 configured as described above, the switch 15 is turned on via the shaft 17, thereby starting the motor 7. Further, when the motor 7 is activated, the screw 9 starts to rotate in the foaming chamber 8.

  Further, when the operation unit 4 is pressed, the shaft 12 moves in the Z1 direction against the spring force of the coil spring 11, and the valve body 13 is opened. As a result, the detergent composition stock solution B in the stock solution tank 5 flows into the foaming chamber 8 via the communication portion 18.

  The screw 9 produces the foam A for washing | cleaning by mixing and stirring the cleaning agent stock solution B and air which flowed in the foaming chamber 8, and has the function to send this out to the arrow X1 direction. At the end of the foaming chamber 8 in the arrow X1 direction, a foam discharge port 16 that opens into the hand insertion portion 3 is formed. The cleaning foam A generated by the screw 9 in the foaming chamber 8 is discharged from the foam discharge port 16.

  On the other hand, when the user releases the pressing operation of the operation portion 4, the shaft 12 is moved upward (moved in the Z2 direction) by the elastic restoring force of the coil spring 11, and the communication portion 18 is closed by the valve body 13. Thereby, the inflow of the detergent composition stock solution B from the stock solution tank 5 to the foaming chamber 8 is stopped. Further, as the shaft 12 moves upward, the operation unit 4 also moves up, and thus the shaft 17 also moves up. Thereby, the switch 15 is turned OFF and the motor 7 is stopped. Further, the rotation of the screw 9 is stopped by the stop of the switch 15, and the discharge of the cleaning bubbles A is also stopped.

  As shown in FIG. 1, in the actual foam generating device 1, an operation unit 4 is provided in the manual insertion unit 3. For this reason, the user can receive the cleaning foam A discharged from the foam discharge port 16 in his / her palm by inserting the hand into the hand insertion section 3 and operating the operation section 4.

  According to the above-described method for generating foam A for cleaning and the foam generating apparatus 1, since the detergent composition stock solution B and the air are mixed by the rotation of the screw 9 rotated by the motor 7, Foam A can be produced (this will be described later).

  Further, unlike the conventional foam generation method using a pump former, clogging does not occur because the mesh member is not used, and the service life can be extended. Further, in the case of the pump former, it is necessary to push the push button strongly, and the usability is bad. However, in the foam generating device 1, simply by inserting the hand into the hand insertion portion 3 and operating the operation portion 4 for cleaning. Since the bubbles A are discharged to the palm, usability can be improved.

  Moreover, in the foam production | generation method which concerns on this embodiment, since the combustible liquefied gas (propellant) required with an aerosol container is not used, the improvement of safety can be aimed at. In addition, since the detergent composition stock solution B can be replenished to the stock solution tank 5, it is not discarded every time it is used like an aerosol container, and further, there is no volatilization of liquefied gas, and the environment. Easy bubble generation method can be realized.

  Furthermore, in the foam generating method and the foam generating apparatus 1 according to the present embodiment, the cleaning foam A starts to be generated immediately when the motor 7 is activated and the screw 9 rotates. Therefore, the time until the cleaning bubbles A can be taken out is short, and this can also improve the usability.

  Next, the characteristics of the cleaning foam A generated as described above will be described.

  FIG. 4 is a diagram showing the foam viscosity of the cleaning foam A generated by the foam generation method and the foam generation apparatus 1 described above in comparison with the foam viscosity of the cleaning foam generated by the conventional foam generation method. It is. This foam viscosity measurement was carried out using a tuning fork type vibration viscometer (SV-10, manufactured by A & D).

  In the figure, Reference Example 1 shows the foam viscosity of a cleaning foam produced using a conventional pump former. Moreover, what is shown as the reference example 2 in the same figure has shown the foam viscosity of the foam for washing | cleaning produced | generated by the electric foam production | generation method using the conventional foam stone. Furthermore, what is shown as an example in the figure shows the foam viscosity of the foam A for cleaning produced by the foam production method and the foam production apparatus 1 described with reference to FIGS. 1 and 2. In the figure, the number described as n = indicates the number of times of measurement, and the characteristic line shown in the figure is an average value thereof.

  In the same figure, the vertical axis indicates the bubble viscosity (mPa-s), and the horizontal axis indicates the elapsed time (sec) after the cleaning bubbles are generated. Here, the fineness and creaminess of the foam correlate with the foam viscosity, and the higher the foam viscosity, the finer the cream texture becomes. The elapsed time was measured at 5 second intervals up to 40 seconds when the cleaning foam was generated for 10 seconds.

  The same detergent composition stock solution was used in each of Reference Examples 1 and 2 and Examples. Specifically, a detergent composition stock solution having the composition shown as Example 1 in FIG. 5 was used. The detergent composition stock solution according to Example 1 contains a surfactant (anionic surfactant and amphoteric surfactant), and the content of the surfactant is 0.4 mass% to 12 mass%. Therefore, the content of the surfactant is set to be smaller than the detergent composition stock solution generally used as a shampoo or the like. Further, the viscosity (liquid viscosity) of the detergent composition stock solution according to Example 1 is 5 mPa-s or more and 1500 mPa-s or less at 30 ° C.

  In FIG. 4, when attention is paid to the foam viscosity of the foam A for cleaning produced by the foam production method according to this embodiment shown as an example, the foam viscosity immediately after the foam production is 43 mPa-s to 55 mPa-s. ing. This is a higher value than Example 1 in which the value of the foam viscosity is 20 mPa-s or more and 35 mPa-s or less and Example 2 in which the value of the foam viscosity is 16 mPa-s or more and 21 mPa-s or less. . Therefore, it was proved that the cleaning foam A generated by the foam generation method according to the present embodiment is finer and creamy than the cleaning foam generated by the conventional foam generation method. It was also demonstrated that fine and creamy foam for cleaning was produced despite the low surfactant content in the detergent composition stock solution and could be maintained over time.

  Next, attention is paid to the change in foam viscosity over time.

  The cleaning foam A produced by the foam production method according to the present embodiment has a difference (change over time) between the foam viscosity immediately after foam production (10 sec) and the foam viscosity after 40 seconds (40 sec) after foam production. It is 7mPa-s or more and 23mPa-s or less. In contrast, in Reference Example 1, the change in foam viscosity with time is 4 mPa-s or more and 19 mPa-s or less, and in Reference Example 2, the change in foam viscosity with time is 4 mPa-s or more and 9 mPa-s or less.

  As described above, the cleaning foam A according to the present embodiment has a higher rate of decrease in the foam viscosity over time than the reference examples 1 and 2. However, even after 30 seconds, the foam viscosity of the cleaning foam A according to this embodiment is higher than the maximum value of Reference Example 1 (31 mPa-s) and the maximum value of Reference Example 2 (17 mPa-s). It has become. Therefore, it was proved that the cleaning foam A according to the present embodiment had better foam sustainability, that is, so-called foam retention, as compared with Reference Examples 1 and 2. This indicates that the texture improves the persistence of the foam by producing fine and creamy foam.

  In the experiment for measuring the foam viscosity of the cleaning foam A shown in FIG. 4 described above, a detergent composition stock solution having the composition shown in FIG. The present inventor measured the foam viscosity in the same manner as described above using the detergent composition stock solution having the composition shown in Example 2 instead of the detergent composition stock solution B according to Example 1. The detergent composition stock solution according to Example 2 has a composition similar to a shampoo that has been conventionally used.

  However, this conventionally used shampoo is used as it is because the viscosity of the stock solution (liquid viscosity) is 1500 mPa-s or more at 30 ° C. and the surfactant content is 12% by mass or more. The foam for cleaning formed by mixing air with the cleaning composition of the present invention, the foam viscosity immediately after foam generation is 40 mPa-s or more and 100 mPa-s or less, and the average particle diameter of bubbles contained in the foam immediately after generation However, it cannot be a foam suitable for cleaning of 10 μm to 100 μm. Then, what adjusted the content of surfactant and the viscosity (liquid viscosity) of stock solution so that it was suitable for this invention was used as cleaning agent stock solution (henceforth adjustment stock solution).

As a result, it was possible to produce a cleaning foam having a foam viscosity characteristic substantially equivalent to the characteristic shown in FIG. This indicates that the adjustment stock solution can be used as the cleaning agent composition stock solution B by using the foam production method and the foam production device 1 according to the present embodiment. When the adjustment stock solution of Example 2 is used, the surfactant content increases as compared with the case where the detergent composition stock solution of Example 1 is used, but the feeling of use is similar to that of a commercially available shampoo. As a result, the cost can be reduced compared to Example 1 of the detergent composition stock solution.
FIG. 6 shows the bubbles contained in the cleaning foam A generated by the foam generation method and the foam generation apparatus 1 described above, and the bubbles contained in the cleaning foam generated by the conventional foam generation method. Was observed with a digital microscope. For observation, a digital microscope (VHX-200, Keyence Co., Ltd.) set to a 50x magnification condition was used, and was observed 30 seconds after discharge and 60 seconds after discharge with the cleaning foam generated by each foam generation method. is there. Acquisition of the bubble image was performed by sandwiching a bubble immediately after generation placed on a slide glass with a cover glass. 7 calculates the average diameter of the bubbles contained in the bubbles from the image obtained in FIG. 6, and generates the cleaning bubbles A and the conventional bubbles generated by the bubble generation method and the bubble generation apparatus 1 described above. The size of the bubbles contained in the cleaning foam produced by the method was compared.

  6 (A-1) and 6 (A-2) are images of bubbles contained in bubbles for cleaning generated using a conventional pump former as Comparative Example 1. FIG. 6 (B-1) and 6 (B-2) show images of bubbles contained in cleaning bubbles generated by an electric bubble generation method using conventional foam stone. It is. Further, FIGS. 6A-1 and 6A-2 show examples of the cleaning foam A generated by the foam generation method and the foam generation apparatus 1 described with reference to FIGS. It is the image of the bubble contained in. Furthermore, in each figure, (A-1), (B-1), and (C-1) are images showing the state 30 seconds after the discharge, and (A-2), (B-2) , (C-2) is an image showing a state 60 seconds after discharge.

  The same detergent composition stock solutions were used in Comparative Examples 1 and 2 and in the examples. Specifically, a detergent composition stock solution having the composition shown as Example 1 in FIG. 6 was used. The detergent composition stock solution according to Example 1 contains a surfactant (anionic surfactant and amphoteric surfactant), and the content of the surfactant is 0.4 mass% to 12 mass%. Therefore, the content of the surfactant is set to be smaller than the detergent composition stock solution generally used as a shampoo or the like. Further, the viscosity (liquid viscosity) of the detergent composition stock solution according to Example 1 is 5 mPa-s or more and 1500 mPa-s or less at 30 ° C.

  Further, FIG. 7 shows the average value of the bubble diameters calculated from the bubbles confirmed in the three images of each acquired level, and the number described as n = indicates the measured number of bubbles. In the same figure, the vertical axis indicates the bubble diameter (μm), and shows the average value of the bubble diameter contained in the bubbles after 30 seconds and 60 seconds immediately after the bubble generation in Example 1, Reference Examples 1 and 2. ing.

  6 and 7, it can be seen that the bubble diameter contained in the cleaning foam A generated by the foam generation method according to the present embodiment shown as an example is very fine compared to each comparative example. The average bubble diameter is 80 μm, which is clearly lower than Comparative Examples 1 and 2 where the average bubble diameter is 200 μm. Therefore, it was proved that the cleaning foam A generated by the foam generation method according to the present embodiment is finer and creamy than the cleaning foam generated by the conventional foam generation method. In addition, it was demonstrated that, despite the small amount of surfactant contained in the detergent composition stock solution, fine and creamy cleaning bubbles are produced due to the fine bubbles contained.

  Next, attention is paid to the change in foam viscosity over time.

  The cleaning foam A (Example) produced by the foam production method according to the present embodiment has an average value of the diameter of the bubbles contained in the foam of 130 μm even after 60 seconds after the foam production. Compared with the average bubble diameter of 240 μm and the comparative example 2 of 290 μm, the values are clearly lower. This proves that the fine and creamy foam lasts longer than the cleaning foam produced by the conventional foam production method.

  Next, the hair washing method using the foam A for washing | cleaning which has the above-mentioned foam viscosity characteristic is demonstrated.

  FIG. 3 shows the vicinity of a hair washing table 21 (hereinafter referred to as a shampoo table) in the beauty salon 20. The foam generating apparatus 1 capable of generating the cleaning foam A having a foam viscosity immediately after the foam generation of 40 mPa-s or more and an average value of the bubble diameter contained in the foam immediately after the generation is 1 mm or less is Installed on the shelf 22. The shelf 22 is where cosmetic containers 23 and towels used for washing hair are placed. The foam generation device 1 is installed on the shelf 22 that is easily accessible to the salon staff who performs hair washing for the person to be washed.

  FIG. 8 is a diagram illustrating a process of a hair washing process performed by a salon staff on a person to be washed. When the hair washing process is started, the salon staff guides the person to be washed to the shampoo table 21 (step 10). Then, after the hair-washer's head is positioned on the shampoo table 21, the salon staff inserts his hand into the hand insertion unit 3 of the foam generating device 1 and operates the operation unit 4.

  As described above, the foam generating apparatus 1 is configured so that the fine creamy cleaning bubbles A are immediately discharged from the foam discharge port 16 to the palm by operating the operation unit 4. Therefore, the salon staff can easily pick up the cleaning bubbles A having good characteristics without performing troublesome button pressing operations such as a pump former and an aerosol container (step 12).

  Subsequently, the washing foam A generated by the foam generating device 1 is applied to the hair of the person to be washed and the hair washing process is started (step 14). In the hair washing method according to the present embodiment, the foam for cleaning A in a foamed state is discharged from the foam generating device 1, so that the foaming process required when using a conventional liquid shampoo is not required. Therefore, the salon staff's hair washing process can be reduced.

  In particular, as a hair shampooing operation of a salon staff for a long-haired woman, the lathering foam in the vicinity of the scalp is transferred to the hair tip to achieve cleaning other than the scalp. In the present invention, in addition to the necessity of the foaming process, the foam taken in step 12 can be directly applied to the hair tip, and the hair tip can be smoothly washed. As a result, the workability of the salon staff can be improved.

  Furthermore, since the foam A for washing | cleaning has good foam retention as mentioned above, the foam of the foam A for washing | cleaning is maintained during hair washing. As a result, for the hair-washed person, the feel of fine creamy bubbles lasts long while washing the hair, and a good impression can be given to the hair-washed person.

  When the hair washing process using the cleaning foam A is completed, the salon staff rinses off the cleaning foam A (step 16), thereby completing the hair washing process.

  As described above, the detergent composition stock solution B, which is the basis for generating the foam A for cleaning, has a surfactant-less composition compared to a general shampoo, and uses the hair washing method of this embodiment. This eliminates the need for lathering for the person performing the shampooing operation, so the contact time with the surfactant and water can be shortened, preventing skin irritation and rough hands. can do.

  The present inventor asked the hair salon to carry out the above hair washing method at a beauty salon for two weeks and conducted a questionnaire on the feeling of use to 11 salon staff who carried out this hair washing method. As a result, by using the hair washing method according to the present embodiment, there was obtained a result that the skin did not irritate or rough hands compared to the conventional general hair washing method.

  It has also been found that the amount of cleaning foam A used can be reduced compared to conventional liquid shampoos. Further, it was also found that the cleaning foam A has an advantage that it spreads well to the hair and can prevent entanglement of the hair. Thus, by using the hair washing method according to the present embodiment, various advantages that cannot be obtained by the conventional hair washing method can be obtained.

Hereinafter, other examples of the cleaning composition for producing the cleaning foam of the present invention will be described. In addition, all of these prescription examples can be prepared by a conventional method, and when foaming with the foam generating device 1, despite the content less than the surfactant of the commonly used detergent composition, It is possible to realize the generation of foam for cleaning having fine cream and excellent foam durability.
