  FIG. 1 shows an example of a foam generating device having a screw. In the foam generating device 1, the hand insertion portion 3 is formed on the front side of the main body portion 2. Moreover, the operation part 4 is provided in the upper part of the main-body part 2, and if the user of the foam generation apparatus 1 operates the operation part 4, as will be described later, the foam cleaning agent A ′ is discharged from the discharge port 16. Discharged. Further, a lid 6 is provided on the top plate of the main body 2, and the lid 6 is opened when the foam cleaning composition A is loaded into the stock solution tank 5 in the main body 2. .

  Inside the foam generating device 1, a tank 5, a motor 7, a foam generating chamber 8, a screw 9 and an opening / closing valve 10 are provided.

  The operation 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 tank 5 is filled with the foam cleaning composition A. When the amount of the foam cleaning composition A in the tank 5 decreases, the lid 6 provided on the main body 2 is opened and the tank 5 is filled with the foam cleaning composition A. . Thus, the foam generator 1 can replenish the foam cleaning composition A.

  The motor 7 is configured to be driven and stopped by the 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 a pressing operation (operation in the Z1 direction) of the operation unit 4.

  The rotation shaft of the motor 7 protrudes into the bubble generation chamber 8. The rotation shaft of the motor 7 passes through the wall portion of the bubble generation chamber 8 and protrudes into the bubble generation chamber 8. The penetration portion is sealed and has a liquid-tight configuration. Further, a screw 9 is disposed at a portion of the rotating shaft of the motor 7 protruding into the bubble generating chamber 8. For this reason, the screw 9 is rotated by the motor 7.

  The bubble generation chamber 8 communicates with the tank 5, and an open / close valve 10 is provided at the communication portion 18 between the tank 5 and the bubble generation chamber 8. The valve body 13 of the opening / closing valve 10 is configured to be able to open / close the communication portion 18 between the tank 5 and the bubble generation chamber 8. When the valve element 13 is opened, the foam cleaning composition A flows into the foam generation chamber 8 from the tank 5. Moreover, when the valve body 13 is closed, the inflow of the foam cleaning composition A from the tank 5 into the foam generation chamber 8 is stopped.

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

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

  When the operation unit 4 is pressed in the foam generating device 1, the switch 15 is turned on via the shaft 17 and the motor 7 is activated. Further, when the motor 7 is activated, the screw 9 starts to rotate in the bubble generation 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 foam cleaning composition A in the tank 5 flows into the foam generation chamber 8 via the communication portion 18.

  The screw 9 generates foam in the foam cleaning composition A by mixing and stirring the foam cleaning composition A that has flowed into the foam generation chamber 8, and sends the foam cleaning composition A in the X1 direction. At the end of the bubble generating chamber 8 in the X1 direction, a discharge port 16 that opens into the manual insertion portion 3 is formed, and the foam cleaning agent A ′ is discharged from the discharge port 16.

  On the other hand, when the user releases the pressing operation of the operation unit 4, the shaft 12 moves in the Z <b> 2 direction by the elastic restoring force of the coil spring 11, and the communication unit 18 is closed by the valve body 13. Thereby, the inflow of the foam cleaning composition A from the tank 5 to the foam generation chamber 8 is stopped. As the shaft 12 moves in the Z2 direction, the operation unit 4 also moves in the Z2 direction, and the shaft 17 also moves in the Z2 direction. Thereby, the switch 15 is turned off and the motor 7 is stopped. Further, by stopping the switch 15, the rotation of the screw 9 is also stopped, and the discharge of the foamy cleaning agent A ′ is also stopped.

  A method for washing hair, skin and the like using the foamy detergent A ′ is not particularly limited, and a method for washing hair, skin and the like using a known detergent can be used. As the foam cleaning agent A ′ used for washing hair, skin and the like, the foam cleaning agent A ′ immediately after generating bubbles by mixing air is preferable in consideration of cleanability and feel of use. However, it is not particularly limited as long as it is fine and creamy foam detergent A ′. For example, it is possible to use the foam cleaning agent A ′ after 30 seconds after mixing air to generate bubbles.

Aqueous citric acid aqueous solution Appropriate amount Purified water Residue The above components were mixed by a conventional method to prepare a foam cleaning composition A. It was 45 mPa * sec when the viscosity of the composition A for foaming detergents was measured at 30 degreeC using the B-type viscosity meter.

  Foam was generated in the foam cleaning composition A using a laser mate (Okuno Denki Sangyo Co., Ltd.) having the same configuration as the foam generating apparatus having the screw of FIG. 1 to generate foam cleaning agent A ′.

  FIG. 2 shows the measurement results of the foam viscosity of the foam detergent A ′ after 10, 20, 30, and 40 seconds after generating the foam. The foam viscosity of the foam detergent A ′ is an average value measured seven times at 30 ° C. using a tuning fork type vibration viscometer SV-10 (manufactured by A & D).

  FIG. 3 shows the average bubble diameter of the foam cleaning agent A ′ after 30 seconds and 60 seconds after generating bubbles. The average bubble diameter of the foam cleaning agent A ′ is obtained using a digital microscope VHX-200 (manufactured by Keyence Corporation) after the foam cleaning agent A ′ is placed on a slide glass and sandwiched between cover glasses. Calculated from the measured images.

  Next, when the hair was washed using the foam cleaning agent A ′ immediately after the generation of foam, the fine and creamy state was maintained, and the cleanability and feel of use of the foam cleaning agent A ′ were improved. I found it excellent.

  From the above, foam detergent A ′ having a foam viscosity after 10 seconds and an average foam diameter after 30 seconds of 40 to 100 mPa · second and 10 to 100 μm, respectively, is generated from the surfactant. It can be seen that even if the content is small, it is excellent in cleanability and use feeling.

[Comparative Example 1]
In the same manner as in Example 1, except that a commercially available pump former container (manufactured by Yoshino Kogyo Co., Ltd.) of a type in which a two-mesh is adopted is used instead of the laser mate (manufactured by Okuno Electric Industrial Co., Ltd.) Foam was generated in the detergent composition A, and the foam viscosity of the foam detergent A ′ after 10, 20, 30, and 40 seconds was measured.

  FIG. 2 shows the measurement results of the foam viscosity of the foam detergent A ′ after 10, 20, 30, and 40 seconds after generating the foam.

  FIG. 3 shows the average bubble diameter of the foam cleaning agent A ′ after 30 seconds and 60 seconds after generating bubbles.

  Next, when the hair was washed using the foam cleaning agent A ′ immediately after the generation of the foam, the foam was easy to disappear, the texture was fine and the creamy state was not maintained, and the foam cleaning agent A ′. It was found that the cleanability and feel of use of this product were low.

[Comparative Example 2]
A foam was generated in the foam cleaning composition A in the same manner as in Example 1 except that the wash wash face washing set EH2611P (manufactured by Panasonic) was used instead of the laser mate (manufactured by Okuno Electric Industrial Co., Ltd.). The foam viscosity of the foam cleaning agent A ′ after 10, 20, 30 and 40 seconds was measured.

  FIG. 2 shows the measurement results of the foam viscosity of the foam detergent A ′ after 10, 20, 30, and 40 seconds after generating the foam.

  FIG. 3 shows the average bubble diameter of the foam cleaning agent A ′ after 30 seconds and 60 seconds after generating bubbles.

  Next, when the hair was washed using the foam cleaning agent A ′ immediately after the generation of the foam, the foam was easy to disappear, the texture was fine and the creamy state was not maintained, and the foam cleaning agent A ′. It was found that the cleanability and feel of use of this product were low.

  From the above, since the foam cleaning composition A has a low surfactant content, a pump former container (manufactured by Yoshino Kogyo Co., Ltd.) or an Awash Wash Face Wash Set EH2611P (manufactured by Panasonic) It can be seen that even when foam is generated in the foam cleaning composition A, the foam cleaning agent A ′ having a low cleaning property and a feeling of use is generated. On the other hand, in the foam cleaning composition A, the foam viscosity of the foam cleaning agent A ′ after 10 seconds and the average bubble diameter of the foam cleaning agent A ′ after 30 seconds are generated. It can be seen that when foams are generated so as to be 40 to 100 mPa · sec and 10 to 100 μm, respectively, a foamy cleaning agent A ′ having excellent detergency and use feeling can be obtained.
