Description

  The present invention relates to a non-aerosol foam discharge hair cleaning product and a hair cleaning composition.

Foam discharge hair detergent products that are used by discharging the hair detergent composition from the container in the form of foam can greatly simplify the time and effort of washing the hair and scalp easily. Convenient for cleaning.
On the other hand, a type of hair cleanser product that is used by discharging the hair cleansing composition from the container into a liquid (liquid discharge type) is used after the hair cleansing composition is discharged from the container in the hand. It is necessary to wash the hair after lathering, and this action is difficult for children, the elderly and the sick.
In addition, the liquid discharge type hair cleaning product may cause hair damage due to friction between hairs when foaming the hair cleaning composition on the hair. On the other hand, the foam discharge hair cleaning product has an effect of preventing this hair damage.

Various foam discharge hair cleaning products having these advantages have been proposed.
For example, an aerosol-type foam discharge hair cleansing product containing a surfactant and a propellant has been proposed (see Patent Documents 1 and 2).
Moreover, the non-aerosol type foam discharge hair cleaning product accommodated in the former container which does not use a propellant is also proposed (refer patent documents 3-5).
JP-A 61-289023 Japanese translation of PCT publication No. 2003-501452 JP 2001-172166 A JP 2000-336019 A JP 2002-256298 A

However, the aerosol-type foam discharge hair cleansing product described in Patent Documents 1 and 2 requires a propellant, and therefore, when the contents contained in the container are used up and discarded, in terms of safety and environment, There's a problem.
In addition, the aerosol-type foam discharge hair cleanser product has a problem that the contents cannot be used up and the hair cleanser composition cannot be refilled into a container.

  On the other hand, the discharge amount of the hair cleaning composition discharged from the container of the non-aerosol foam discharge hair cleaning product described in Patent Documents 3 to 5 is generally used for liquid discharge type hair cleaning products. Compared with the typical discharge amount from the container (3 g per operation for discharging the hair detergent composition from the container to the hand). In order to obtain the same performance as when using a liquid discharge type hair cleaning product, the number of operations is doubled or more in order to make the discharge amount of the hair cleaning composition discharged from the container the same. It is necessary and troublesome. Therefore, non-aerosol foam discharge hair cleanser products are shampoos for children that can be used even if the amount of hair cleanser composition used is small, when the number of operations is the same as liquid discharge type hair cleanser products. If it is not in the field, satisfactory performance (for example, hair cleaning properties, conditioning properties after cleaning, etc.) cannot be obtained, and the versatility is poor.

  On the other hand, the solution by setting many discharge amounts of the hair cleaning composition discharged from a container can be considered. However, in the conventional non-aerosol type foam discharge container, when a large amount of discharge is set, foam formation becomes unstable, creamy foam cannot be obtained, and it is difficult to wash the hair, resulting in poor usability. There is.

  Further, in the conventional non-aerosol type foam discharge container, there is a problem that foam formation becomes unstable when a cationic polymer is blended in order to impart conditioning properties after washing.

  The present invention has been made in view of the above circumstances, and a stable foam is produced even when a large amount of the hair cleaning composition is discharged from a container and a cationic polymer compound is blended. It is an object of the present invention to provide a non-aerosol foam discharge hair cleanser product that is obtained and has excellent foam creaminess, usability such as ease of washing, and conditioning after washing.

This is a non-aerosol foam discharge hair cleansing product characterized in that the mixing ratio of the hair cleansing composition and air is 1/12 to 1/25 (g / cm ³ ).
The hair cleansing composition preferably further contains (D) an emulsion containing amino-modified silicone particles having an average particle size of less than 0.15 μm, water and an emulsifier.

When n is 2 or more, the adduct (alkyl sulfate salt) of the alkylene oxide repeating unit having an addition mole number of 0 is reduced, and the mildness and storage stability of the hair cleaning composition are improved. On the other hand, when n is 6 or less, the cleaning power is improved and stickiness after rinsing or after cleaning is suppressed.
In addition, the polyoxyalkylene alkyl ether sulfate includes a plurality of adducts having different addition mole numbers of alkylene oxide repeating units, and the addition mole number distribution of the alkylene oxide repeating units has the following features. preferable.
In the polyoxyalkylene alkyl ether sulfate, in the total adduct, the maximum addition mole number M of the adduct distribution ratio of the alkylene oxide repeating unit is not 0 (the total number of added moles of the alkylene oxide repeating unit is 0). Are most often not included). That is, it is preferable that the alkyl sulfate salt that is presumed to have an adverse effect on the mildness and storage stability of the hair cleansing composition is not contained in the largest amount.
The distribution of the adduct (alkyl sulfate salt) having 0 addition moles is preferably 19% by mass or less, more preferably 15% by mass or less, and the lower limit is preferably 3% by mass or more.

Among these, a pump-type former that is used by pressing the head (nozzle) of the cap with fingers is preferably used because the hair cleaning composition and air can be easily mixed at a certain ratio.

In general, the discharge amount of the hair cleaning composition per time from the container and the mixing ratio of the hair cleaning composition and air can be adjusted by appropriately controlling the structure of the container used. It is.
As an example, a pump-type former container will be described below with reference to the drawings.

One embodiment of a non-aerosol type foam discharge container used in the present invention is shown in FIG.
The non-aerosol type foam discharge container 1 in FIG. 1 includes a container body 2 and a nozzle body 3 and includes a cap 21.
The nozzle body 3 includes a cylinder 4, a liquid piston 6, a mixing unit 8, and a nozzle 9.
Two porous films 11, 11 are arranged above the mixing unit 8 by the net holder 10. An air piston 12 is disposed at the lower end of the net holder 10.
The liquid piston 6 has a composition take-in portion 14, which is a space through which the hair cleansing composition accommodated in the container body 2 is fed through the dip tube 20. The liquid piston 6 is urged upward by a coil spring 18 when not in use.
In addition, an inner rod 16 is disposed at the center of the composition take-in portion 14. When this inner rod 16 is not used, it is pulled up by the liquid piston 6, and the gap between the inner rod 16 and the liquid piston 6 is sealed to block the upper end of the composition intake portion 14. ing.
On the other hand, the inside of the cylinder 4 is an air intake portion 13. The air piston 12 is arranged so as to close the vent hole 17 of the cylinder 4. Thereby, it is prevented that the hair-cleaning-agent composition accommodated in the container main body 2 mixes in the cylinder 4 via the dip tube 20.

When the hair detergent composition is discharged from the non-aerosol foam discharge container 1, the nozzle 9 is pressed with fingers. Thereby, a hair-cleaner composition is discharged in foam form from a nozzle discharge port.
At this time, the air piston 12 and the liquid piston 6 are integrally pushed down. The inner rod 16 is lowered later than the liquid piston 6, so that a gap is generated between the inner rod 16 and the liquid piston 6. And a hair-cleaner composition is sent in into the mixing part 8 from this clearance gap.
Therefore, by adjusting the volume of the composition take-in portion 14 in the liquid piston 6 and the distance (stroke) to which the nozzle 9 is pushed down, the discharge amount of the hair cleaning composition per time from the container is controlled. It becomes possible. Thereby, this discharge amount can be 1.7 g or more.

On the other hand, when the air piston 12 is pushed down, the vent hole 17 of the cylinder 4 is opened and air is sent into the mixing unit 8 from the air intake unit 13, and the air and the hair cleaning composition are mixed in the mixing unit 8. Mixed. And the mixture of air and a hair-cleaner composition passes through the porous membranes 11 and 11, becomes foamed, and is discharged from a nozzle discharge port.
Therefore, by adjusting the volume of the air intake portion 13 in the cylinder 4, the amount of air fed into the mixing portion 8, etc., the mixing ratio of the hair cleaning composition and air can be controlled. . Thereby, the quantity of the air with respect to 1 g of hair cleaning composition can be 12-25 (cm < ³ >).

In the example of FIG. 1, the amount of the hair cleaning composition contained is about 550 (mL).
The volume of the composition intake 14 is about 2 (mL).
The volume of the air intake part 13 is about 30 (mL).
The height of the non-aerosol type foam discharge container 1 (from the bottom surface of the container body 2 to the top of the cap 21) is 21.5 (cm).
The diameter of the bottom surface of the container body 2 is 8.5 (cm).

≪Hair cleaning composition≫
The hair cleansing composition of the present invention comprises (A) an anionic surfactant, (B) a monovalent lower alcohol and / or polyhydric alcohol, (C) a cationic polymer compound, and (D) an average particle. An emulsion containing amino-modified silicone particles having a diameter of less than 0.15 μm, water and an emulsifier is contained.
The hair cleansing composition of the present invention is the same as the hair cleansing composition in the non-aerosol foam discharge hair cleaning product except that the component (D) is an essential component. Therefore, (A) component, (B) component, (C) component, other components, the preparation method, etc. are all the same as the hair cleaning composition in the non-aerosol foam discharge hair cleaning product, Description of the common configuration is omitted.

In the hair cleansing composition of the present invention, the component (D) is an essential component. By containing this (D) component, the conditioning property after washing | cleaning improves and it is excellent also in the high temperature stability of the hair-cleaner composition with time.
The amino-modified silicone particles constituting the emulsion, water and emulsifier, preparation method, average particle size, etc. are the same as those in the above-mentioned non-aerosol foam discharge hair cleanser product, and common configurations are described. Is omitted.

The hair cleansing composition containing the component (D) according to the present invention is excellent in conditioning properties after cleaning, and is excellent in high-temperature stability of the hair cleaning composition over time. The reason for this is not clear, but is presumed as follows.
The amino-modified silicone contained in the component (D) has good adsorptivity to hair among silicones. Therefore, it is considered that a sufficient amount of amino-modified silicone can be adsorbed to the hair and remain after rinsing.
In addition, the amino-modified silicone particles contained in the component (D) have a smaller average particle diameter than commonly used silicone particles. Therefore, it is considered that it is easy to adsorb uniformly and finely on the hair.
Further, since the amino-modified silicone particles have a small average particle size, it is considered that they can be stably dispersed in the hair cleaning composition. Therefore, it is considered that the amino-modified silicone particles are hardly aggregated even under storage at a high temperature, and good dispersibility can be maintained.
For these reasons, it is surmised that the hair cleansing composition containing the component (D) according to the present invention is excellent in conditioning properties after cleaning and is also excellent in high-temperature stability of the hair cleaning composition over time. .
