Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to an aerosol spray product for hair styling.

[0002]

2. Description of the Related Art In recent years, various spray-type hair styling products, such as the following, have been used for the purpose of easily fixing hair disorder by supplying water to the hair to make it soft and soften it. Commercially available spray hair styling products such as those described in 1., aerosol spray hair styling products using compressed gas as a propellant, and aerosol spray hair styling products using liquefied gas as a propellant are commercially available.

A manual pump type spray hair styling product called hair blow spray or styling water is mainly composed of 5 to 30% by weight of ethanol, 0.1 to 1% by weight of a cationic surfactant and a balanced amount of water. This is a manual pump container filled with the stock solution of the hairdressing composition. In the case of this product, by manually operating (pumping) a manual pump, the hair styling agent stock solution having a relatively high water content is sprayed in a mist form from the nozzle.

Further, aerosol spray hair styling products using compressed gas as a propellant are roughly classified into two types. One of them is to fill a pressure-resistant container for aerosol spraying with a stock solution of a hair styling agent having a relatively large water content similar to that of the above-mentioned manual pump type spray styling product, together with a compressed gas such as nitrogen gas. In this case, the jet A of the mechanical breakup structure (FIG. 1) is used, and the hairdressing agent stock solution is jetted as mist from the jet. The other is 40 to 70% by weight of ethanol, 0.1 to 1 medicinal properties.
A stock solution of a hair tonic agent mainly consisting of water in a weight percentage and a balance amount was filled in a pressure container for aerosol spray together with a compressed gas such as carbon dioxide gas or nitrogen gas. In the case of this product, although the mist forming ability is low, a straight structure (FIG. 2) or a forward taper structure (FIG. 3), which can spray the contents in a narrow pattern to a long distance, is used. The hair tonic agent composition is jetted from the nozzle A as a jet jet. Although this product is originally used as a hair tonic spray or a hair growth spray, it is also used as a hair styling aerosol spray.

Further, an aerosol spray hair styling product containing liquefied gas as a propellant contains 50 to 85% by weight of ethanol,
An undiluted hair dressing solution mainly composed of 15 to 50% by weight of water and 1 to 10% by weight of a film-forming component (for example, acrylic resin) is used as a liquefied gas (propellant) such as liquefied petroleum gas (LPG) or dimethyl ether (DME). ) Together with a pressure-resistant container for aerosol spray at a weight ratio of undiluted solution / propellant = 50/50. For this product,
In the actuator of the pressure vessel, it is not possible to eject a long distance, but a fine mist can be formed and the mist can be ejected to a relatively wide area area. Reverse taper structure (Fig. 4) or mechanical breakup structure The nozzle A shown in FIG. 1 is used, and the hairdressing solution is sprayed as a mist from the nozzle.

[0006]

However, in the case of the conventional manual pump-type spray hair styling product described above, the amount of the stock solution of the hair styling agent that can be injected by one pumping is small and the injection pressure is low, so that the hair is There is a problem that a considerable number of pumping must be carried out in order to spread the hair styling agent stock solution in an amount sufficient for fixing disorder such as the sleeping habit of the above all over the hair, especially at the root of the hair.

[0007] Further, in the case of an aerosol spray hair styling product in which a conventional compressed gas is used as a propellant to spray a stock solution of a water-containing hair styling agent into a mist, the spraying force is extremely weak because there is no vaporization phenomenon of the propellant. However, there is a problem that it is not possible to supply the hair styling agent stock solution in an amount sufficient for fixing the disorder of the hair to the root of the hair.

Further, in the case of an aerosol spray product in which a conventional compressed gas is used as a propellant and a stock solution of a hair styling agent such as a hair tonic agent is jetted as a jet jet, the stock solution of the hair styling agent is locally supplied to the root of the hair. However, if you try to supply the hair styling concentrate to the entire area of a certain area where it is necessary to correct the disorder of hair habits etc., the amount used will become excessive and dripping will occur, which will drip on the face. There is a problem of soiling clothes. Further, since the hair styling solution is locally supplied, there is a problem that it is not easy to surely supply it to an intended portion. Furthermore, the stock solution for hairdressing has a large amount of ethanol, so that it is easy to dry and it is not possible to sufficiently permeate water into the hair.

On the other hand, in the case of the conventional aerosol spray hair styling product using liquefied gas as a propellant, the liquefied gas expands at the time of jetting, so that the hair styling stock solution is jetted in a mist at a relatively high jet pressure. Have. This advantage makes it possible to uniformly supply the undiluted solution of the salifying agent to the entire area where the disorder such as the sleeping habit of the hair should be corrected. But,
The stock solution of the hair styling agent used in this case has a high ethanol content, and since the filling ratio of the propellant is relatively high, it is easy to dry. Therefore, in the case of conventional aerosol spray hairdressing products that use liquefied gas as a propellant,
There is a problem in that the permeation of water into the hair makes it impossible to sufficiently fix the disorder such as the sleeping habit of the hair and adjust the hair.

Further, in general, the aerosol spray products as described above are required not only to fix hair disorder such as sleeping habit but also to be able to set hair without stickiness. There is.

The present invention is intended to solve the above-mentioned problems of the prior art, and supplies a quick and sufficient amount of water to the area where the disorder of the hair is desired to be corrected and the root of the hair in that area, and the sleeping habit of the hair and the like. It is an object of the present invention to provide an aerosol spray product for hairdressing, which can satisfactorily correct the irregularity of the hair and has excellent setting properties.

[0012]

Means for Solving the Problems The present inventor has proposed a propellant consisting of dimethyl ether and a hair styling stock solution containing ethanol, a hair-fixing polymer compound and water in a specific compounding ratio in a pressure container for aerosol spraying. In order to complete the present invention, it was found that an aerosol spray product for hair styling, which is obtained by filling and in a specific range with an injection amount per unit time set to a specific value or more, can achieve the above-mentioned object. I arrived.

That is, the present invention provides the following components (A) to
(C) (A) ethanol 1 to 50% by weight (B) hair-fixing polymer compound 0.05 to 5% by weight (C) water hair dressing solution containing a balance amount, and a propellant composed of dimethyl ether, Stock solution / propellant = 60/40 to 90/10 (weight ratio), and the injection amount at 25 ° C. is 8

Among them, salts of 2-amino-2-methylpropanol and 2-amino-2-methyl-1,3-propanediol can be preferably used.

Among the polymer compounds for fixing hair as the component (B), the polymer compound having a basic group is
It is preferable that a part or all of the basic group is converted into a salt by neutralization. Such salts are not particularly limited, but as the inorganic acid salts, salts of inorganic acids such as hydrochloric acid, sulfuric acid, phosphoric acid and the like are preferable, and as the organic acid salts, acetic acid, lactic acid, glycolic acid, dimethylolpropionic acid And salts of organic acids such as tartaric acid, citric acid, maleic acid, malic acid and pyrrolidone carboxylic acid.

In addition to the hair-fixing polymer compound described above, a water-dispersible polyester resin may be used as the hair-fixing polymer compound of the component (B). Such water-dispersible polyester resin, as long as it can be dispersed in water in a water-insoluble is not specifically limited, among others, a sufficient amount of -SO ₃ M groups to disperse in water (M is a hydrogen atom Or a metal ion).

Examples of such polyesters include Eastman
Commercial products such as AQ 38S and 55S (manufactured by Eastman Chemical Products) can be used.

The component (C), water, is used to soften the hair and make it easier to fix the hair.

The amount of the component (C) water blended is such that the component (A) ethanol and the component (B) hair-fixing polymer compound are added from the whole stock solution of the hair styling agent, and other additives added as necessary. The amount excluding and. In this case, if the blending amount of water is too small, the hair cannot be sufficiently softened, so it is preferable to blend it in the stock solution of the hair styling agent in an amount of at least 60% by weight or more.

The hair styling liquid concentrate used in the present invention further includes
As the component (D), it is preferable to use a polyether-modified silicone oil that is soluble in a mixed solution of water and ethanol in order to improve the uniformity of spraying. In this case, it is preferable to use an HLB value of 5 or less. As a result, the uniformity of the spray can be improved, and in particular at a low temperature, it can be remarkably improved. Here, the HLB value corresponds to a value obtained by dividing the numerical value of the weight% of the polyether portion (usually polyoxyethylene portion) in the polyether modified silicone oil by 5.

When the amount of the polyether-modified silicone oil as the component (D) is too small, a uniform and clean spray cannot be performed, and when the amount is too large, the spray spreads too much. Since the hair dressing solution concentrates on hairs other than the above and it becomes difficult to supply the hair dressing solution to the root of the hair, the hair dressing solution preferably contains 0.0005% by weight to 0.005% by weight, more preferably 0.0008% by weight.
% To 0.002% by weight.

As the polyether-modified silicone oil of component (D), those conventionally used in hair cosmetics can be used. For example,
Polyoxyethylene / methylpolysiloxane copolymer,
Poly (oxyethylene / oxypropylene) methylpolysiloxane copolymer and the like can be preferably used. Specifically, SH3775E (Toray Dow Corning Silicone Co., Ltd., HLB value 5), KF945A
(Shin-Etsu Chemical Co., Ltd., HLB value 4.5), KF60
15 (Shin-Etsu Chemical Co., Ltd., HLB value 4.5), KF
6016 (Shin-Etsu Chemical Co., Ltd., HLB value 4.5),
KF6017 (Shin-Etsu Chemical Co., Ltd., HLB value 4.
5) and the like.

The hair styling liquid concentrate used in the present invention includes:
Various additives commonly used in hair cosmetics as needed, such as oily components, surfactants, powder components, humectants, viscosity modifiers, organic solvents, bactericides, preservatives, antioxidants, An ultraviolet absorber, a fragrance, a crude drug and the like can be appropriately compounded.

In the aerosol spray product for hairdressing of the present invention, a propellant composed of dimethyl ether (DME) is used to spray the stock solution of hairdressing agent. This is DM
Since E has a high solubility in water, it can be mixed evenly with the stock solution of the hair styling agent in the pressure resistant container for aerosol spray even in the compounding range of the component (A) ethanol, which is relatively lower than the conventional one, and thus the hair styling at the time of spraying. This is because the stock solution of the agent can be easily ejected as a uniform mist.

In addition to dimethyl ether, another propellant (for example, LPG) may be added within a range in which the hair styling liquid concentrate and the propellant can be uniformly mixed in the pressure container for aerosol spraying. .

In the present invention, the mixing (weight) ratio of the hair styling liquid concentrate and the propellant is as follows: Hair styling liquid concentrate / propellant = 60/40
To 90/10, preferably 65/35 to 80/20. If the mixing ratio of the hairdressing concentrate exceeds 90%, a uniform spray cannot be obtained, and if it is less than 60%, the mist of the spray becomes excessively fine and diffuses. Therefore, water can be effectively supplied to the root of the hair. It becomes difficult to fix hair disorder such as sleeping habit.

In the aerosol spray product for hairdressing of the present invention, the amount of the stock solution of the hairdressing agent is compared to the amount of the stock solution of the hairdressing agent which is sufficient for fixing and setting the disorder of the hair such as sleeping habit. 25 ℃ to supply in a very short time
Is adjusted to 8 g / 10 seconds or more, preferably 10 g / 10 seconds or more, and more preferably 10 to 16 g / 10 seconds. The injection amount of the stock solution of the hair styling agent in the present invention is set to a very high value as compared with the injection amount (2 to 4 g / 10 seconds) of the conventional aerosol spray product for hair styling.

In the present invention, the injection amount of the hair styling aerosol spray product is adjusted depending on the composition of the hair styling agent concentrate, the mixing ratio of the hair styling agent and the propellant, the injection port shape of the injection button, etc., but mainly the valve hole diameter (stem hole diameter, This can be done by adjusting the housing hole diameter) and the injection button hole diameter. However, if the stem hole is made excessively large, it becomes difficult to obtain a uniform spray, so it is effective to make the housing hole sufficiently large. Examples of combinations of such hole diameters include a stem hole diameter of 0.4 mm, a housing hole diameter of 2.0 mm, and a button hole diameter of 0.6 mm.

The hair styling aerosol spray product of the present invention can be produced by a conventional method. For example, components (A) to (C) and, if necessary, components (D) and other additives are uniformly dissolved or dispersed to prepare a hair styling solution, and the solution is used together with a propellant. It may be filled in a pressure container for aerosol spray. In this case, as the pressure container for aerosol spraying, various types can be used, but it is preferable to use a pressure container for aerosol spraying having a jet port of a mechanical breakup structure.

As described above, the aerosol spray product for hairdressing of the present invention uses the stock solution of hairdressing agent in which ethanol, the polymer compound for fixing hair and water are blended in the specified ranges. Therefore, it is possible to satisfactorily correct disturbances such as sleeping habits of the hair by supplying sufficient water to the hair, and also have excellent setting properties. Furthermore, the hair spray aerosol spray product of the present invention uses dimethyl ether having a specific blending ratio as a propellant, and its spray amount is adjusted to 8 g / 10 seconds or more. Therefore, the hair spray aerosol spray product of the present invention can evenly supply the stock solution of the hairdressing agent evenly to the root of the hair, without evenly distributing the hair in the portion where hair disorder such as bed habit is desired to be corrected.

In particular, when a polyether-modified silicone oil having an HLB value of 5 or less is added, it is possible to spray the stock solution of hair styling agent in a mist form with a good spraying property even with a smaller amount of propellant than before. .

As can be seen from Tables 1 to 3, Examples 1 to 1
The hair styling aerosol spray product of No. 8 of the present invention was not evaluated as “x” in any of the evaluation items, and showed excellent results.

On the other hand, as can be seen from Table 4, in the case of the aerosol spray product for hair styling of Comparative Example 1, ethanol was excessively used in the stock solution of the hair styling agent, so that water was particularly sufficiently supplied to the hair. It had dried before and the effect of fixing the sleeping habit was insufficient. Further, in the case of the aerosol spray product for hair styling of Comparative Example 2, since the amount of the polymer compound for fixing hair was too large, there was a problem of stickiness especially after drying. In the case of Comparative Example 3, the hair-fixing polymer compound was not used, so that there was a problem particularly in the retention of the hairstyle. In the case of Comparative Example 4, since the amount of the propellant compounded in the stock solution was too large, there was a problem in terms of "spray characteristics". In the case of Comparative Example 5, the amount of the propellant compounded with respect to the stock solution was too small, and therefore there was a problem in terms of "spray characteristics".

Comparative Example 6 The stem hole diameter of the aerosol spray pressure-resistant container (stem hole diameter 0.4 mm / housing hole diameter 2.0 mm / jet button hole diameter 0.6 mm) having the mechanical break-up structure of the nozzle used in Example 1 was changed. An aerosol spray product for hairdressing was manufactured in the same manner as in Example 1 except that the size was 0.3 mm and the housing hole diameter was 0.3 mm. The amount of spray of this hair styling aerosol spray product is 5.6 g /
10 seconds. Therefore, the aerosol spray product of Comparative Example 6 could not sufficiently supply the stock solution of the hairdressing agent to the root portion of the hair, and further could not quickly supply the sufficient stock solution of the hairdressing agent to the entire hair.

In the case of Example 1, since the injection could be performed at an amount of 11.4 g / 10 seconds as described above, the injection amount is the hole of the valve (stem hole, housing hole, etc.). It can be seen that the diameter can be adjusted by changing the diameter.

Example 9 A hair styling aerosol spray product was prepared in the same manner as in Example 1 except that a hair styling solution concentrate was prepared according to Table 5, and the mixing ratio of the stock solution and dimethyl ether (propellant) was as shown in Table 5. Was manufactured.

For the obtained aerosol spray product, in the same manner as in Example 1, "familiarity with hair", "effect of correcting habit of sleeping", "easiness of gathering hairstyle", "holding hairstyle", "after drying" When evaluated for "non-stickiness" and "spray characteristics", the same preferable results as in Example 1 were obtained.
