Description

  The present invention relates to a hair cosmetic capable of preventing damage to hair, specifically, a hair cleaning agent, an in-bass type hair protecting agent, and a method of using the same.

In general, gel-like or cream-like hair cleaning agents (including shampoos) and hair protecting agents (including hair treatments, hair conditioners, rinses, etc.) are widely used.
Gel-like or cream-like hair cleaners rub against each other after they are applied to the hair, so that the hair can be scratched by friction between the hairs, resulting in split ends, dryness, and glossy fingers. There is a problem that damage such as street degradation occurs.
In addition, gel-like or cream-like hair protecting agents are rubbed into the hair and applied, so that there is a problem that the hair can be scratched by friction between the hairs, which also leads to damage.
Moreover, since many oil components (about 20%) are mix | blended with the general gel-like or cream-like hair protectant, it takes time to wash away, and the hair is easily damaged. Furthermore, many oil components remain in the hair even after rinsing, making it difficult to dry. Therefore, it takes a long time to dry with a dryer, and the friction of the hair and the amount of heat of the dryer are increased, resulting in hair damage.
As described above, the gel- or cream-like hair cleansing agent and the hair protecting agent that are generally widely used and the method of using the same have a problem of causing friction to the hair and leading to damage.

  On the other hand, hair cleansing agents and hair protection agents for non-gas formers, which are excellent in ease of use and smoothness during use, and conditioning effects have been reported (Patent Documents 1 and 2). However, the hair damage preventing effects of these non-gas former hair cleansing agents and hair protecting agents are insufficient.

[Non-gas type former container]
In the hair cosmetic composition of the present invention, the composition of the present invention has three or more porous bodies having an eye roughness of 100 to 500 mesh, and the discharge amount of the composition per time is 3 ml. It is characterized by being accommodated in the above-described non-gas type former container.
Since the composition of the present invention is suitable for a non-gas type former container having such a structure, the foamed hair cosmetic composition of the present invention to be discharged has a fineness of foam, uniformity, cushioning and volume feeling. Since it is excellent and rubbing due to friction between hairs is reduced and it is easy to wash away, damage to the hair can be prevented.

  The non-gas type former container of the present invention mixes the composition of the present invention contained in a container and air, and discharges the mixture from the container discharge port as foam.

  The discharge amount of the composition of the present invention from the non-gas type former container of the present invention (volume of liquid before foaming) is 3 ml or more, preferably 3 to 10 ml, more preferably 8 to 10 ml. It is. When the discharge amount is 3 ml or more, the amount becomes sufficient as the foamy hair cosmetic of the present invention, and the performance (cleaning property of hair, conditioning property after cleaning, etc.) is improved. On the other hand, the upper limit value of the discharge amount is not particularly limited, but by setting it to 10 ml or less, the pressing pressure of the container such as the nozzle is not excessively heavy at the time of discharge, and it is easy to push, and the foam hair cosmetic is discharged from the container. It is easy to obtain a stable foam.

In addition, "per once" means that the number of operations for causing the foamed hair cosmetic composition of the present invention to be discharged from the container to the hand is one time. For example, in the case of a pump-type former container, it means that the number of pumping times is one, and in the case of a squeeze-type former container, the number of squeeze times is one.
Further, the “discharge amount” is an average value of the amount of the composition of the present invention discharged from the container discharge port by the operation of manually discharging the foamed hair cosmetic of the present invention from the non-gas type former container of the present invention. Say.
In addition, even if a small number of discharges per time are discharged, a large volume can be obtained. However, since bubbles disappear sequentially while discharging a plurality of times, the cushioning property may be impaired. .

The mixing ratio of the composition of the present invention and air (composition of the present invention / air) in one operation of discharging the foamed hair cosmetic composition of the present invention from the non-gas type former container of the present invention is preferably 1. / 12 to 1/25 (g / cm ³ ), more preferably 1/14 to 1/20 (g / cm ³ ). When the mixing ratio is less than 1/25 (g / cm ³ ), the foam-forming property is deteriorated, and it becomes difficult to apply the discharged material to the hair or scalp. On the other hand, in the range exceeding 1/12 (g / cm ³ ), creamy foam is not obtained and usability such as ease of washing deteriorates.
In the present invention, the “mixing ratio of the composition of the present invention and air” refers to the composition of the present invention in the non-gas type former container of the present invention at 15 to 25 ° C. (preferably 20 ° C.). It represents the volume (cm ³ ) of air mixed per gram.
Moreover, the said mixing ratio is the present invention when the discharge amount of the composition of this invention becomes the maximum in one operation which discharges the foamy hair cosmetics of this invention from the non-gas type former container of this invention. The average value of the mixing ratio of the composition and air is shown.

Further, the foam volume of the foamed hair cosmetic of the present invention discharged from the non-gas type former container of the present invention is preferably 10 to 30 mL per operation for discharging the composition of the present invention from the container, More preferably, it is 20-25 mL. When the foam volume is 10 mL or more, the amount of foam discharged from the non-gas type former container of the present invention to the palm is sufficient, the foam formation is improved, and the cushioning and volume feel can improve the hair. The friction between each other is reduced, and it is possible to effectively prevent damage such as split ends, dryness, and deterioration of gloss and fingers due to scratches. On the other hand, when it is 30 mL or less, the foam-forming property is improved, and the amount of the composition of the present invention in the foam is sufficient, so that the cleaning power and the conditioning property are improved.
The “foam volume” is 15 to 25 ° C. (preferably 20 ° C.), and the discharged material discharged from the non-gas type former container of the present invention is discharged into the beaker (capacity 100 mL). The average value which measured the quantity of the foam | bubble by the volume of water and the frequency | count of discharge is said.

When the average diameter of the foam is within this range, the fineness, cushioning, and volume of the foam of the foamed hair cosmetic composition of the present invention are further improved, and the rubbing caused by friction between the hairs is reduced. Damage can be effectively prevented. When the average diameter of the foam exceeds this range, the fineness of the foam becomes insufficient and the hair is easily damaged. Moreover, when the average diameter of the foam is less than this range, the foam becomes hard and it becomes difficult to adjust to the hair.
Further, the standard deviation of the foam diameter of the foam hair cosmetic composition of the present invention discharged from the non-gas type former container of the present invention is not particularly limited, but is preferably 0.5 mm or less, more preferably 0.2 mm or less, More preferably, it is 0.06 mm or less. When the standard deviation of the diameter of the foam is within this range, the foam fineness of the foamed hair cosmetic of the present invention is further improved in the uniformity of foam fineness, cushioning and volume feeling, and is rubbed by friction between the hairs. This can reduce hair damage effectively.
The average value and the standard deviation of the foam diameter of the foamed hair cosmetic composition of the present invention can be obtained by image analysis of an enlarged photograph of the foam immediately after being discharged from the non-gas type former container of the present invention.

The foam viscosity at 25 ° C. of the foam hair cosmetic composition of the present invention discharged from the non-gas type former container of the present invention is not particularly limited, but is preferably 250 to 1000 mPa · s, more preferably 300 to 900 mPa · s, More preferably, it is 350-800 mPa * s. When the viscosity of the foam is within this range, the fineness, uniformity, cushioning and volume of the foam are further improved, rubbing due to friction between hairs is reduced, and hair damage is effectively prevented. be able to. When the viscosity of the foam is higher than this range, it becomes difficult to adjust to the hair and the usability tends to decrease. When the viscosity of the foam is lower than this range, cushioning properties are lowered, dripping is likely to occur, and hair tends to be easily damaged.
The apparent viscosity of the foam at 25 ° C. can be measured 100 seconds after the start of measurement at a shear rate of 100 s ⁻¹ using a cone plate rheometer.

  The non-gas type former container of the present invention is characterized by comprising three or more porous bodies having a fixed pore size (mesh), whereby the fineness of the foamed hair cosmetic composition of the present invention, cushioning property, Volume feeling is further improved, rubbing due to friction between hairs is reduced, and hair damage can be effectively prevented. The upper limit of the number of porous bodies is not particularly limited, but is preferably 5 or less. When the number of porous bodies exceeds 5, when the foamed hair cosmetic of the present invention is discharged from the non-gas type former container of the present invention, the pressing pressure becomes too heavy or the foam viscosity becomes too high. Then, the usability may be inferior.

The mesh of the porous body (the number of holes per 1 cm ² ) is not particularly limited, but the lower limit is preferably 100, more preferably 150, still more preferably 200, and the upper limit is preferably 500, More preferably 400, still more preferably 300. When the porous mesh is within this range, the fineness, uniformity, cushioning, and volume of the foam are further improved, rubbing due to friction between hairs is reduced, and hair damage is effectively prevented. Can be prevented.
The meshes of the three or more porous bodies may be the same or different.

Especially, since the composition of this invention and air can be easily mixed in a fixed ratio, the pump type | former used by pressing the head part (nozzle) of a cap with a finger is used preferably.

In general, the discharge amount of the composition of the present invention per container, the average value and standard deviation of the diameter of the foam, the viscosity, etc. are the same as the composition of the composition of the present invention and the non-gas type former container of the present invention. This structure can be adjusted by appropriately controlling the structure.
As an example, a pump-type former container will be described below with reference to the drawings.

One embodiment of a non-gas type former container (pump type former container) 1 used in the present invention is shown in FIG.
The pump-type non-gas type former container of the present invention shown in FIG. 1 includes a container body 2 and a nozzle body 3.
The nozzle body 3 includes a nozzle 4, a liquid piston 5, and the like at an upper portion, and further includes a cylinder, an air chamber, a gas-liquid mixing portion (not shown) in which air and the composition of the present invention are mixed.
A cylindrical passage 11 through which the gas-liquid mixed liquid passes in a direction substantially perpendicular to the bottom surface of the container main body is disposed above the gas-liquid mixing portion of the nozzle body 3. Two porous bodies 6 and 7 are arranged up and down substantially perpendicular to the flow direction of the liquid mixture. The upper part of the cylindrical passage 11 is curved at a substantially right angle with respect to the cylindrical passage 11 and is provided with a nozzle discharge port 10, and a porous body 8 further flows in the flow direction of the gas-liquid mixture at the nozzle discharge port 10. It is arranged substantially perpendicular to.

The inner diameter cross-sectional area of the flow path of the nozzle discharge port 10 is narrower than the inner diameter cross-sectional area of the flow path of the cylindrical passage 11, whereby the gas-liquid mixture of the composition of the present invention and air is discharged from the cylindrical passage 11. When moving to the nozzle discharge port 10, the flow velocity becomes faster and the shearing force when the gas-liquid mixture passes through the porous body 8 can be increased, so that the discharged bubbles tend to be finer and more uniform. . Therefore, it is preferable to provide at least one of the three or more porous bodies at the nozzle discharge port 10.
The ratio (the former / the latter) of the inner diameter cross-sectional area of the flow path of the nozzle discharge port 10 and the inner diameter cross-sectional area of the flow path of the cylindrical passage 11 is not particularly limited, but the discharged bubbles are made finer and more uniform. Therefore, 1/2 to 1/10 is preferable, and 1 / 2.5 to 1/5 is more preferable.

The inner diameter cross-sectional area of the flow path of the nozzle discharge port 10 is not particularly limited, but in order to make the discharged bubbles more fine and uniform while ensuring the flow of the gas-liquid mixture, it is 10 to 40 mm ^2. Is preferable, and 15 to 35 mm ² is more preferable.

  The inner diameter cross-sectional area of the flow path of the nozzle outlet 10 may be the same over the entire path, but may not be the same. For example, the diameter may be gradually reduced from the boundary portion of the nozzle discharge port 10 to the cylindrical passage 11 to the porous body 8 disposed inside the nozzle discharge port 10. The diameter may be gradually increased from the position to the opening end of the nozzle discharge port 10 on the downstream side. When the flow path of the nozzle discharge port 10 takes such a shape, bubbles are smoothly discharged, and it becomes easy to ensure the fineness and uniformity of the bubbles.

The porous bodies 6, 7, and 8 may be formed of any material, for example, metals and various resins. Moreover, the shape of the porous bodies 6, 7, and 8 is not particularly limited, but is preferably a mesh-like thin film. In this case, the areas of the porous bodies 6, 7, and 8 are the same as the inner diameter cross-sectional area of the flow path of the cylindrical passage 11 and the inner diameter cross-sectional area of the flow path of the nozzle outlet 10, respectively. Further, the thickness of the porous bodies 6, 7, and 8 with respect to the flow direction of the gas-liquid mixed liquid is not particularly limited, but the discharged bubbles are made finer and more uniform while ensuring the flow of the gas-liquid mixed liquid. Therefore, 10-1000 micrometers is preferable and 50-500 micrometers is more preferable.
In addition, the raw material, shape, area, thickness, etc. of the porous bodies 6, 7, 8 may be the same or different.

The composition of the present invention accommodated in the container body 2 is fed into the liquid piston 5 through the dip tube 9 and mixed with air in the gas-liquid mixing section.
When the composition of the present invention is discharged from the non-gas type former container 1 of the present invention, the nozzle 4 is pressed with fingers. As a result, the composition of the present invention mixed with air passes through the porous bodies 6, 7 and 8 in order and becomes foamed, and the foamed hair cosmetic of the present invention is discharged from the nozzle discharge port 10.
By adjusting the volume in the liquid piston 5, the distance (stroke) to which the nozzle 4 is pushed down, etc., it becomes possible to control the discharge amount of the composition of the present invention from the container once. Thereby, the discharge amount can be 3 ml or more.

In the example of FIG. 1, the amount of the composition of the present invention accommodated in the container body 2 is about 450 (mL).
The height of the non-gas type former container 1 of the present invention (from the bottom surface of the container body 2 to the upper part of the nozzle 4) is 19 (cm).
The diameter of the bottom surface of the container body 2 is 4.2 (cm).

(2) Take the foamy hair cleanser of the present invention and apply it to the hair and scalp.
(3) Wash the hair and scalp without rubbing the hair.
(4) Rinse with hot water.
(5) Take the foam-like hair protectant of the present invention and pat the hair.
(6) Rinse with hot water.
(7) Pull out the hair with a towel and dry it with a dryer.

In this process, the cause of frictional damage can be solved in the following points.
(3) The hair cleanser of the present invention is foamy, and it is not necessary to rub the hairs together to foam, and no friction occurs.
(5) Since the hair protecting material of the present invention is foamy and fits without being rubbed into the hair, there is no friction.
(6) Since there are few oil components, it can wash out easily and friction does not arise between hairs.
(7) There is almost no oil component residue on the hair and it is easy to dry, and there is very little friction between the hairs during drying.

  Moreover, in the usage method of the hair cosmetics of this invention, it is considerably speedy compared with the conventional usage method in all processes, such as application | coating, foaming, washing off, and drying. There is an advantage in workability not only for home use but also for business use in a hairdressing salon.

[Effect of the hair cleaning agent of the present invention]
(1) In conventional hair cleansing agents, the hair is rubbed due to friction, and damage caused by split ends, dryness, and glossy fingering caused by it. The hair cleaning agent of the present invention can wash hair without causing frictional damage.
(2) The foam produced on the hair in the conventional hair cleanser has a large variation, and the size is as large as an average of about 0.8 mm. As a result, the surface is washed out evenly and it is difficult to wash the pores (average size of about 0.2 mm). The foam of the hair cleansing agent of the present invention is uniform with very little variation and a small average size of 0.15 to 0.25 mm. Therefore, it can be washed well into the pores without unevenness.
(3) Although the conventional hair cleanser takes a considerable amount of time and labor to foam, the hair cleanser of the present invention does not need to be foamed, so the working time is shortened. This is a great advantage especially for business use in a hairdressing salon.
(4) In the hairdressing and beauty salon, the problem of rough hands of staff due to repeated shampoos is serious, and is the top cause of retirement of young staff. Although wearing gloves is effective for preventing rough hands, there are many cases where gloves are pulled when the hair is rubbed, which is unacceptable because it causes discomfort to the customer. Since the hair cleansing agent of the present invention does not rub the hair, it does not give unpleasant feelings to customers even when wearing gloves. This can solve the problem of rough staff.

[Effect of the hair protecting agent of the present invention]
(1) Because conventional hair protectants are creamy with a lot of oil components, the hair has been rubbed by friction due to rubbing by application, long-running and drying operations, and this is the cause. Damages such as split ends, dryness, and deterioration of glossiness and fingering. The hair protectant of the present invention can improve hair conditioning without causing frictional damage.
(2) Conventional hair protectants generally have a cream form, and the oil component concentration is about 20% because it forms a cream form. For this reason, the finish tends to give a moist and coherent feeling, but it is difficult to produce a voluminous and soft feeling. Since the liquid hair protectant of the present invention is foamed with a former container, the oil component concentration can be suppressed to about 0.1 to 3.0%. Therefore, there is an advantage that the finished product is easy to produce a voluminous and soft feeling.
(3) Since the conventional hair protectant has a high oil component concentration, it is easy to form a film on the surface of the hair, and the penetrating power into the hair is weak. For this reason, active ingredients such as repair ingredients and moisturizing ingredients are less effective to the inside of the hair. Since the hair protecting agent of the present invention has a low oil component concentration, it has a strong penetration into the hair. Therefore, the active ingredient is easy to work to the inside of the hair, and a moist feeling and a cohesive feeling can be realized from the inside of the hair.
(4) Since the conventional hair protectant has a high oil component concentration, the oil component tends to remain in the hair even after washing. For this reason, it takes time to dry with a dryer, and frictional damage between the hairs tends to increase, and damage due to heat for a long time is also likely to be added. Since the hair protecting agent of the present invention has a low oil component concentration, the oil component hardly remains in the hair after washing. Therefore, it can be dried quickly with a dryer, and frictional damage and heat damage between hairs can be greatly reduced.

[Hair cosmetic set]
The hair cosmetic composition of the present invention may be used alone as a hair cleanser, or may be used alone as a hair protectant, but is a combination of the hair cleanser of the present invention and a hair protectant. It is preferable to use it as a set. By using both as a set of the hair cleansing agent and the hair protecting agent of the present invention and foaming both, it is possible to prevent frictional damage of the hair more efficiently.

As in the above method of using hair cosmetics, it is common to wash and wash hair with a hair cleansing agent, then treat and wash hair with an in-bass type hair protectant, and then dry it.
After washing and washing hair with the hair cleansing agent of the present invention, for example, when treating and washing hair with a conventional creamy bath type hair protectant, the hair is rubbed at the stage of treatment with the hair protectant. The hair is damaged by being combined, and since it takes time to dry with a dryer, damage to the hair due to heat cannot be avoided.
In addition, for example, in the case of washing and washing hair with a conventional creamy hair washing agent, even if the hair protectant of the present invention is used thereafter, damage caused by rubbing the hairs at the stage of washing the hair Cannot be avoided.
Therefore, damage to hair can be avoided for the first time by using it as a set of the hair cleansing agent and hair protecting agent of the present invention.

  Hereinafter, the present invention will be described in more detail using examples, but the present invention is not limited to these examples.

Example 1: Preparation of a hair cleanser (shampoo) Each component was mixed in the composition shown in Table 1 and diluted with water to adjust the whole to 100 parts by weight. It was put in the container body 2 of the former container 1 to obtain a hair cleaning agent (shampoo).

Example 2: Preparation of hair protectant (treatment) The components shown in Table 2 were mixed, diluted in water, and adjusted to 100 parts by weight as a whole. It was put in the container body 2 of the former container 1 to obtain a hair protecting material (treatment).

[Evaluation of hair damage by washing hair]
Using a conventional creamy shampoo (apple cell mask shampoo, Sunny Place) and a foamy shampoo discharged from the hair cleansing agent obtained in Example 1, 30 hair samples (N = 5) were continuously added. Washed twice.
Select five hairs with a constant thickness from the washed hairs. Tensile strength (g unit) was measured using an apparatus of XT Plus (manufactured by Stable Micro Systems). Moreover, the enlarged photograph of the obtained hair is shown in FIG. 2 (conventional shampoo) and FIG. 3 (shampoo of Example 1).

  According to Table 3, the shampoo of Example 1 maintains the strength of the hair as compared with the conventional shampoo, and the hairs obtained by repeating the conventional shampoo according to FIGS. It was found that the hair obtained by repeating the shampoo of Example 1 was not damaged, and the shampoo of Example 1 was superior in hair protecting effect.

[Evaluation of bubble diameter and standard deviation]
An enlarged photograph of a foam obtained by lightly lathering a conventional cream shampoo (Appulecel Mask Shampoo, Sunny Place) with the palm of the hand was taken. As shown in FIG.
In addition, an enlarged photograph of foam was obtained by foaming a conventional cream shampoo (Appulecel Mask Shampoo, Sunny Place) firmly on the hair. As shown in FIG.
Moreover, the enlarged photograph of the foamy shampoo discharged from the hair cleaning agent obtained in Example 1 was taken. As shown in FIG.
5 and 6 are subjected to image analysis using a microscope image analysis system (inverted microscope IX-71, microscope camera DP-72, manufactured by Olympus Corporation), and the average value (mm) of the diameter of the bubbles is calculated. Standard deviation (mm) was determined. A graph showing the average value (mm) and the dispersion is shown in FIG.

4 to 6, in the case of the conventional shampoo, the foam becomes fine when foamed firmly on the hair, but it can be seen that the shampoo of Example 1 is a finer foam when it is discharged from the former container. .
From FIG. 7, the size of the foam obtained by foaming the conventional shampoo on the hair is 0.8 mm on average and the standard deviation is 0.67 mm. In comparison, it can be seen that the shampoo of Example 1 has a uniform size of bubbles discharged from the container with an average size of 0.2 mm and a standard deviation of 0.06 mm.

[Evaluation of hair permeability of treatment]
Foam in which a conventional cream treatment (fabric treatment, manufactured by Risoh Kaken) is colored in red and a hair protectant obtained in Example 2 is colored in red from a non-gas type former container The same amount of the treatment was applied to each decolorized hair specimen, left for 30 minutes, washed away, and taken in an enlarged cross-sectional photograph. They are shown in FIGS. 8 and 9, respectively.
8 and 9, it can be seen that the conventional treatment has low permeability and does not penetrate into the hair, but the treatment of Example 2 has high permeability and penetrates into the hair.

[Evaluation of ease of drying]
Apply the same amount of the conventional treatment and the foam-like treatment discharged from the hair protecting agent obtained in Example 2 to the hair bundle, leave it for 10 minutes, wash it off, and dry it with a drier (Nobby Specialist NB1900, manufactured by Nobby, 1200W). The dry speed was tested by measuring the time (seconds) required to return from the washed-out state to the original dry state. The results are shown in Table 4.
In addition, the conventional treatment was made into the average value of the following three products.
・ Product A: Kitson Airy Hair Treatment, manufactured by Risoh Kaken (cream)
・ Product B: Salon only treatment n, made by Henkel Japan (cream)
・ Product C: Apple Cell Mask Treatment, Sunny Place (Cream)

  It can be seen that the hair treated with the conventional treatment took 214.66 seconds to dry, whereas the hair treated with the treatment of Example 2 could be dried in 172.02 seconds and dried quickly.
