Description

Hair cosmetic preparation and preparation method thereof

The present invention relates to a cosmetic preparation for hair, and more particularly to a cosmetic preparation for hair comprising a multi-agent for self-foaming and foaming a cosmetic for hair when mixed with each other, and a method for producing the same.

Conventionally, a hair cosmetic, a liquid or a paste, which is used as a hair bleaching agent or a hair dye, is popular. However, compared with cosmetics for liquid or creamy hair, foam-like hair cosmetics which can be easily applied and which have the advantage of not being uneven when applied are gradually popularized. For the foam-like hair cosmetic, for example, an aerosol-type hair cosmetic (for example, Patent Document 1) and an aerosol-free hair cosmetic (for example, Patent Document 2) are known.

The cosmetic for aerosol type hair uses a propellant to foam the hair cosmetic. Therefore, a special container is required, and there is a problem that the pressure vessel is corroded or the internal pressure rises, and the container is difficult to be discarded after use. In addition, in the case of the non-aerosol-type hair cosmetic, in order to easily obtain a foam-like hair cosmetic, the viscosity of the mixed cosmetic of the hair cosmetic is lowered, and there is a problem that dripping occurs at the time of use.

A. Implementation type A-1. Composition of hair cosmetic group:

Fig. 1 is a view schematically showing the composition of a cosmetic set 10 for hair in an embodiment of the present invention. The hair cosmetic group 10 includes a mixing container 100, a mixing device 200, a first agent 300, and a second agent 400. Hereinafter, the first agent 300 and the second agent 400 are collectively referred to as "hair cosmetic preparation agent".

The first agent 300 and the second agent 400 are each a liquid or a paste which is accommodated in a storage container (for example, a tubular container). The composition of the first agent 300 and the second agent 400 is set to be a hair cosmetic (dyeing agent or decolorizing agent) when they are mixed with each other. Further, the first agent 300 contains a carbonate (sodium hydrogencarbonate) component, and the second agent 400 contains an acid component which decomposes carbonate. Therefore, when the first agent 300 and the second agent 400 are mixed, the carbonate contained in the first agent 300 reacts with the acid contained in the second agent 400 to generate bubbles (oxidation bubbles). The detailed components of the first agent 300 and the second agent 400 will be described later.

The mixing container 100 is a cup-shaped container that is stored when the first agent 300 and the second agent 400 are mixed, and is formed of a resin (for example, PP). The mixing device 200 is a flat-shaped (spoon-shaped) device for mixing the first agent 300 and the second agent 400 stored in the mixing container 100, and is formed of a resin (for example, PP).

A-2. Hair cosmetic treatment:

Fig. 2 is a flow chart showing a flow of a hair cosmetic preparation process using the hair cosmetic set 10. In addition, FIG. 3 and FIG. 4 are explanatory views showing an outline of a hair cosmetic preparation process using the hair cosmetic set 10.

First, the hair cosmetic set 10 including the mixing container 100, the mixing device 200, the first agent 300, and the second agent 400 as shown in Fig. 1 is prepared (step S110). Next, the first agent 300 and the second agent 400 are transferred from the storage container to the mixing container 100 (step S120). FIG. 3 shows a state in which the first agent 300 and the second agent 400 are moved from the storage container to the mixing container 100.

Then, the first agent 300 and the second agent 400 which have been moved to the mixing container 100 are mixed using the mixing device 200 (step S130). FIG. 3 shows a state in which the first agent 300 and the second agent 400 are mixed using the mixing device 200. When the first agent 300 and the second agent 400 are mixed by using the mixing device 200, the carbonate contained in the first agent 300 reacts with the acid contained in the second agent 400 to generate bubbles (carbon dioxide). Thereby, a foam-like hair cosmetic is produced in the mixing container 100. FIG. 4 shows a state in which the foam-like hair cosmetic FO is produced in the mixing container 100. Moreover, as shown in FIG. 4, the mixing instrument 200 is also used as an appliance for the foaming hair cosmetics FO which is produced in the mixing container 100.

Or a propellant to obtain a cosmetic for foamy hair. In this case, the user does not need to perform the operation of the container for vibrating the storage agent, and the simple operation of the first agent 300 and the second agent 400 stored in the mixing and mixing container 100 may be performed by using the mixing device 200. Further, in the present embodiment, the hair cosmetic preparation process using the hair cosmetic set 10 is used, and the user can observe that bubbles are generated by mixing the plurality of agents, and the liquid or paste-like plural agent gradually becomes Since the foam-like hair is in the state of the cosmetic material FO, the performance (happiness, excitement) can be improved.

A-3. Method for producing hair cosmetic preparation:

Fig. 5 is a flow chart showing a manufacturing procedure of the first agent 300 in the cosmetic preparation for hair. First, the raw material component of the first agent 300 is divided into an alkali agent (A), a non-acid base (B), an acidic base (C), and a reducing agent (D), and are each selected (step S210).

The carbonate is selected as the alkali agent (A) component. The alkali agent (A) component may be selected from at least one selected from the group consisting of, for example, an alkali metal salt or an alkaline earth metal salt of a carbonate ion, an alkali metal salt or an alkaline earth metal salt of a hydrogencarbonate ion, ammonium carbonate or ammonium hydrogencarbonate. Group of carbonates. Further, the cosmetic content of the hair cosmetic material (that is, the mixed drug of the first agent 300 and the second agent 400) is preferably 1.0% by mass to 30.0% by mass, more preferably 1.5% by mass to 20.0% by mass. Further, in addition to the carbonate, appropriate ammonia water or the like may be added.

The non-acid base (B) is not particularly limited except for being non-acidic. The non-acid base (B) component may be one or a combination of components selected from the group consisting of hair cosmetic materials (dyeing agents, decolorizing agents, and the like) and dosage forms. As the non-acid base component (B), for example, an oxidation dye, a hydrocarbon, an ester, a polyoxyalkylene, a higher alcohol, an animal or vegetable oil, a surfactant, a plant extract, an alcohol, a natural or synthetic polymer, or a fragrance can be used. , refined water, etc. The higher alcohol is particularly preferably one having a carbon number of 10 to 30 (preferably 12 to 24, particularly preferably 14 to 22) or a linear alkyl group or a carbon number of 10 to 30 (equivalent to 12 to 24). Higher alcohols such as cetyl alcohol and stearyl alcohol having an alkenyl group of 14 to 22 are particularly preferred.

The acidic base (C) component is not particularly limited except for its acidity. The acidic base (C) component can be selected from a combination of one or more components depending on the intended use and dosage form of the cosmetic preparation for hair. Since the present embodiment adopts a composition containing a tackifier in the first agent 300, an organic acid such as L-ascorbic acid, citric acid or glycolic acid, phosphoric acid or sulfuric acid can be selected as the acidic base (C) component. A carboxyvinyl polymer such as a mineral acid or the like or a tackifier. Further, as the tackifier, any type of tackifier may be used, but an associative tackifier (neutralizing tackifier) having a tackifying property for use in a specific pH range is particularly preferable. Further, the content of the tackifier in the cosmetic for hair (mixing agent) is preferably such that the viscosity of the cosmetic for hair (mixing agent) is in the range of 1500 mPa ‧ 8 8 mPa ‧ s so as to be 1500 mPa ‧ s The amount within the range of ～30000 mPa·s is better.

The reducing agent (D) component may be, for example, a mercaptocarboxylic acid such as photocysteine or a derivative thereof, a mercaptocarboxylic acid such as thiomalic acid, or a mercaptocarboxylic acid ester such as glycerol or glyceryl thioacetate. One or more components selected from the group consisting of sulfhydryl compounds such as cysteamine and cysteinamide, sulfites such as sulfurous acid and sodium sulfite, bisulfites such as sodium hydrogen sulfite, and ascorbic acid or derivatives thereof.

Next, each of the non-acid base (B) and the reducing agent (D) selected in step S210 is classified into an oil phase obtained from an oil-soluble component, an aqueous phase obtained from a water-soluble component, and a high temperature. The additive phase is made up of unstable components and weighed. Further, each of the alkali agent (A) and the acidic base agent (C) is weighed (step S212). Thereafter, the weighed oil phase component and the water phase component are separately heated and heated (step S214). The aqueous phase adjusted to a certain temperature is added to the oil phase adjusted to a certain temperature to carry out emulsification mixing (step S216). In addition, the above-mentioned constant temperature can be arbitrarily determined in consideration of the component characteristics and the like constituting each agent. This matter is also the same in the following.

After adjusting the emulsified mixture generated in the step S216 to a certain temperature, the components of the additive phase are added (step S218). Thereafter, after adjusting the emulsified mixture obtained in the step S218 to a certain temperature, the weighed alkali agent (A) component is added (step S220). Further, it is preferred to add the alkali agent (A) component at a low temperature. At this stage, the emulsified temperature is alkaline as a whole. Thereafter, after adjusting the alkaline emulsified mixture obtained in the step S220 to a certain temperature, the weighed acidic base (C) component is added (step S222). Further, it is preferred to add an acidic base (C) component at a low temperature. Finally, the emulsified mixture obtained in step S222 is stored in a predetermined container (step S224). In addition, step S216 is also referred to as a first step, step S220 is a second step, and step S222 is a third step.

As described above, in the production step of the first agent 300 in the present embodiment, the acidic base agent (C) component is added after the alkali agent (A) component is added to the emulsified mixture. In the emulsified mixture, by adding the components in the order described above, since the alkali agent (A) component, that is, the carbonate salt, can be added while maintaining the alkaline state, the carbonate can be prevented from coming into contact with the emulsified mixture in an acidic state to cause foaming.

Fig. 6 is a flow chart showing a manufacturing procedure of the second agent 400 in the cosmetic preparation for hair. First, the raw material components of the second agent 400 are classified as a base (E), a pH adjuster (F), and an oxidizing agent (G), and are selected (step S310).

The base (E) component is not particularly limited. As the base (E) component, a combination of one or more components can be selected depending on the intended use and dosage form of the cosmetic preparation for hair. As the base (E) component, for example, a hydrocarbon, an ester, a polyoxyalkylene, a higher alcohol, an animal or vegetable oil, a surfactant, a plant extract, an alcohol, a natural or synthetic polymer, a fragrance, purified water or the like can be used.

As the pH adjuster (F) component, an acid which can decompose the carbonate contained in the first agent 300 is selected. At least one or more acids selected from the group consisting of organic acids such as citric acid and glycolic acid, inorganic acids such as phosphoric acid and sulfuric acid, and the like can be selected. In addition, when it is used to reduce the dyeing hair cosmetic for hairiness, the pH adjuster is preferably selected such that the hair cosmetic (mixed drug) is in the range of pH 1.0 to 9.0. The amount in the range of pH 3.0 to 7.0 is particularly preferred. On the other hand, when it is used to improve the dyeing, bleaching, and bleaching of the cosmetic for hair, the pH adjuster is selected such that the hair cosmetic (mixed drug) is in the range of pH 6.0 to 9.0. Preferably, it is preferred to select a portion in the range of pH 7.0 to 8.5. In addition, "bleaching and discoloring of hair" means decolorization of melanin in hair. In addition, "staining of hair" means changing the chromaticity and brightness of hair by oxidation of an oxidative dye. In addition, in the case of "staining of hair", it is also possible to change the chromaticity and brightness of the hair by oxidation of the oxidative dye while bleaching and decolorizing the hair.

As the (G) acidifying agent component, for example, urea peroxide, melamine peroxide, sodium perborate, potassium perborate, potassium percarbonate or the like can be selected, for example, hydrogen peroxide, hydrogen peroxide or an oxygen generating agent.

Next, each of the base agent (E), the pH adjuster (F), and the oxidizing agent (G) selected in the step S310 is classified into an oil phase obtained from an oil-soluble component, an aqueous phase obtained from a water-soluble component, The additive phase obtained by increasing the temperature of the unstable component is weighed (step S312). Thereafter, the weighed oil phase component and the water phase component are separately heated and heated (step S314). The aqueous phase adjusted to a certain temperature is added to the oil phase adjusted to a certain temperature to carry out emulsification mixing (step S316). After adjusting the emulsified mixture generated in the step S316 to a certain temperature, the components of the additive phase are added (step S318). Finally, the emulsified mixture obtained in step S318 is stored in a predetermined container (step S324).

B. Experimental results:

In the hair cosmetic preparation agent described in the above embodiment, the components contained in the cosmetic preparation for hair and the content thereof are variously changed. The results of various experiments carried out are as follows.

In the various experiments described later, a sample of the first agent 300 manufactured by the method described with reference to FIG. 5 and a method according to FIG. 6 were used using a container having a content of 550 ml ( FIG. 1 ) and a mixing device 200 ( FIG. 1 ). The sample of the second agent 400 produced was mixed at a mixing ratio (weight ratio) of 1:1, and the obtained hair cosmetic (mixed drug) was evaluated. In addition, the mixing is carried out in accordance with the procedure of the hair cosmetic manufacturing process described with reference to Fig. 2 .

B-1. Experimental result 1 (Experimental results on the viscosity of cosmetic products for hair):

Fig. 7 is an explanatory view showing a sample of the first agent 300 used in the experiment of viscosity of a cosmetic for hair. Fig. 8 is an explanatory view showing a sample of the second agent 400 used in the experiment on the viscosity of the cosmetic for hair. Fig. 9 is an explanatory view showing the results of an experiment on the viscosity of a cosmetic for hair. In addition, for convenience, the first agent in the figure is only referred to as "one dose", and the second dose is only referred to as "two doses". In addition, the sample numbers in the figure correspond to the same substance (that is, for example, the evaluation result of the sample #10 shown in FIG. 9 indicates the first agent for the sample #10 of FIG. 7 and the second agent of the sample #10 of FIG. The evaluation result of the obtained cosmetic for hair). These things are the same for other experimental results of subsequent presentations.

In this experiment, first, it is necessary to change the viscosity of the hair cosmetic (mixed drug) by changing the content of the first agent carbonate (potassium carbonate and ammonium hydrogencarbonate) and the content of the tackifier (carboxyvinyl polymer). Samples (samples #10 to #19). Next, for samples #10 to #19, for (1-1) maintaining the foam of the mixed medicament, (1-2) dropping the liquid during application, (1-3) dropping the liquid when placed, (1-4) applying When evaluating the penetration of hair, each item is evaluated. In addition, the viscosity of the mixed drug was used at 20 ° C to defoam the mixed drug (deaerating the foam under vacuum), using a B-type rotational viscometer roller No. 4, and rotating at 6 rpm for 1 minute. The value. The evaluation method and evaluation criteria are shown below.

(1-1) Maintaining the foam of the mixed drug The condition of the first dose sample and the second dose sample was evaluated by visual confirmation. In addition, "defoaming" as used herein means that the foam which is temporarily formed by the reaction of a carbonate with an acid exhibits a tendency to decrease. In addition, the number of stirrings was performed using a mixing device (Fig. 1), and when it was circled around the mixing container (Fig. 1), the count was "1 time".

Maintain the evaluation criteria for the blended foam

A: Even if it is stirred more than 100 times, it is not defoamed.

B: No defoaming even if it is stirred more than 50 times

C: Stir until 50 times, start defoaming

D: no blistering, or stirring immediately begins defoaming

(1-2) Liquid dripping at the time of application was evaluated by 20 assessors for dripping liquid of 150 g of the foam mixed with the entire body of the hair at 25 ° C.

Evaluation criteria for liquid dripping during application

A: When applied to the head, there is no liquid dripping at all.

B: When applied to the head, there is almost no liquid dripping

C: When applied to the head, only a few tiny liquids drip

D: When applied to the head, quite a lot of liquid drops

(1-3) The liquid dripping at the time of standing was evaluated by applying a foam of 150 g of the mixed drug at 35 ° C to the hair of the test person of the hair dye.

Evaluation criteria for liquid dripping during placement

A: Completely no liquid dripping

B: Placed within 30 minutes, no liquid dripping

C: Place it within 30 minutes, only some micro liquid drops

D: Placed within 30 minutes, quite a lot of liquid dripping

(1-4) Permeability to hair was evaluated by 20 assessors on the penetration of hair by applying a foam mixed with a drug at 25 ° C to the hair of the test doll for hair dyeing. Here, the term "permeability to hair" means that the mixed drug rapidly penetrates between the hairs.

Basis for assessing the permeability of hair

A: Excellent permeability to hair

B: good permeability to hair

C: poor permeability to hair

D: almost no permeability to hair

As a result of the evaluation test, the samples #10 to #13 in which the viscosity of the mixed drug was in the range of 1500 mPa ‧ 30,000 to 30,000 mPa ‧ were evaluated A. That is, the samples #10 to #13 are not defoamed even if the foam of the mixed drug is stirred more than 100 times (that is, the foam is durable), and liquid dripping does not occur at the time of application and placement, and the permeability to the hair is excellent. . In addition, the sample #15 having a viscosity of 75400 mPa·s of the mixed drug and the sample #18 having a viscosity of 82,600 mPa·s of the mixed drug, although the foam of the mixed drug was defoamed 50 times, the permeability to the hair was poor, but when applied, And when it is placed, no liquid dripping occurs.

On the other hand, the sample #14 with a viscosity of 750 mPa‧s and the sample #17 with a viscosity of 1200 mPa·s of the mixed drug, the foam of the mixed drug was defoamed 50 times, and a considerable amount occurred during application and placement. The liquid dripped. The sample having a viscosity of 100,000 mPa·s or more of the mixed agent of #100, #19, the foam of the mixed drug could not be foamed, and was completely opaque to the hair (in other words, the permeability to the hair was poor, and the usability was lacking).

From the evaluation of the test results, it is understood that the content of the tackifier in the cosmetic for hair (mixed drug) is preferably such that the viscosity of the cosmetic for hair is in the range of from 1,500 mPa ‧ to 83,000 mPa ‧ s. When the viscosity of the cosmetic for hair is within the above range, the foam can be suppressed by mixing the first agent and the second agent (that is, the mixture of carbonate and acid) by appropriate viscosity. Since the foam is used, it is possible to easily obtain an aerosol-free hair cosmetic having an aerosol-free viscosity at the time of use.

From this, the test results were evaluated, and it was further found that the tackifier content of the cosmetic for hair (mixed drug) was particularly preferably such that the viscosity of the cosmetic for hair was in the range of 1,500 mPa ‧ to 30,000 mPa ‧ s. When the viscosity of the cosmetic for hair is within the above range, it is possible to obtain a cosmetic for hair which has a long-lasting foam for the hair cosmetic material due to an appropriate viscosity, and which has better finger patency during application and is excellent in usability.

B-2. Experimental result 2 (Experimental result 1 on the type of tackifier):

Fig. 10 is an explanatory view showing a sample of the first agent 300 used in the experiment on the type of the tackifier. Fig. 11 is an explanatory view showing a sample of the second agent 400 used in the experiment on the type of tackifier. Fig. 12 is an explanatory view showing the results of experiments on the type of tackifier.

In this experiment, first, it is necessary to change the type of tackifier contained in the first agent (carboxyvinyl polymer, acrylic acid ‧ alkyl methacrylate copolymer, sodium carboxymethyl cellulose, xanthan gum) and the content thereof. Samples (samples #20 to #24). Next, for the samples #20 to #24, the viscosity of the mixed drug was determined, and at the same time, (2-1) the foam of the mixed drug was maintained, and (2-2) the dispersibility of the tackifier was formed during the formation of the first agent. ,to evaluate. In addition, the measurement method of the viscosity of the mixed drug is the same as that described in B-1. Experimental result 1.

The evaluation method and evaluation criteria for (2-1) maintaining the foam of the mixed medicament are the same as (1-1) of B-1. Experimental result 1.

(2-2) The dispersibility of the tackifier at the time of the formation of the first agent is a step of adding a tackifier in the first agent production step, and whether the tackifier is easily dispersed in the preparation is visually confirmed.

Evaluation criteria for the dispersibility of the tackifier when the first agent is formed

A: The tackifier can be easily dispersed in the preparation

B: The tackifier can be dispersed in the preparation

C: The tackifier can be dispersed in the preparation but forms small particles.

D: the tackifier can hardly be dispersed in the preparation

In the results of this evaluation test, the durability of the mixed drug foam was evaluated for all samples (even if it was stirred more than 100 times, it did not defoam). Further, when the adhesion-type adhesives were mixed using the associative tackifier samples #20 to #22, the tackifier was easily dispersed in the preparation. On the other hand, the sample #23 using a tackifier of a non-associative tackifier was added to the tackifier, and small particles were formed in the preparation due to the tackifier. Similarly, when the sample #24 using a non-associative tackifier tackifier was added to the tackifier, the tackifier was not dispersed throughout the formulation.

From the results of the evaluation, it is understood that the tackifier contained in the cosmetic preparation for hair is preferably an associative tackifier (a tackifier which exhibits a viscosity-increasing effect when it is in a specific pH range). When an associative tackifier is used, a step of mixing the tackifier in the manufacturing step of the first agent can provide good dispersibility to the formulation.

Fig. 15 is an explanatory view showing other experimental results regarding the type of tackifier.

This experiment is to change the pH of the first agent and the second agent by changing the potassium hydroxide content of the first agent and the phosphoric acid content of the second agent, thereby changing the carboxyvinyl polymer or carboxymethyl group as a tackifier. A plurality of samples of the cellulose sodium-based agent (samples #30 to #33). Next, for samples #30 to #33, the viscosity of the first agent, the viscosity of the second agent, the viscosity of the mixed drug, and the pH of the mixed drug were determined, and at the same time (3-1) the foam of the mixed drug was maintained ( 3-2) Each item containing the viscosity-increasing agent (the first agent and the second agent) at the time of formation of the tackifier is evaluated. In addition, the measurement method of the viscosity of the mixed drug is the same as that described in B-1. Experimental result 1. Further, the viscosity of the first agent and the second agent was measured at 20 ° C using a roller No. 4 of a B-type rotational viscometer and rotated at 6 rpm for 1 minute.

The evaluation method and evaluation criteria for (3-1) maintaining the foam of the mixed medicament are the same as those of B-1. Experimental result 1 (1-1).

(3-2) Evaluation method and evaluation basis of the dispersibility of the tackifier when the agent containing the tackifier (the first agent and the second agent) is formed and B-2. Experimental result 2 (2-2) )the same.

As a result of the evaluation test, in the samples #30 and #32 in which the amount of potassium hydroxide contained in the first agent was the same, the sample #30 using the associative tackifier (carboxyvinyl polymer) was thicker than the non-associative type. Sample #30 of the drug (carboxymethylcellulose sodium), the first agent has a low viscosity and can reduce the tackifier content. Further, in the samples #31 and #33 in which the amount of the phosphoric acid contained in the second agent was the same, the sample #31 using the associative tackifier (carboxyvinyl polymer) was used as the non-associative tackifier (carboxymethyl group). Sample #33 of cellulose sodium), the second agent has a low viscosity and can reduce the tackifier content.

Further, using the associative tackifier (carboxyvinyl polymer) samples #30 and #31, a tackifier mixture is added to the manufacturing step of the tackifier-containing agent (the first agent and the second agent). In the step, the tackifier is easy to disperse into the formulation. On the other hand, samples #32 and #33 of the non-associative tackifier were used, and the tackifier was not dispersed in the preparation.

As a result of the evaluation of the test, it is understood that the tackifier contained in the cosmetic preparation for hair (mixed drug) is preferably an associative tackifier (a tackifier which exhibits a viscosity-increasing effect when it is in a specific pH range). When the associative tackifier is used, the content of the tackifier is reduced to a low blending amount, and a cosmetic preparation for hair which maintains the viscosity of the blending tackifier or other agents can be produced, and the compound is mixed. In the case of a single agent (the first agent or the second agent), the neutralization reaction is caused by the reaction of the carbonate with the acid, and the hair cosmetic (mixed drug) becomes a pH range suitable for viscosity enhancement, and the viscosity-increasing effect can be exhibited. . Further, the dispersibility of the tackifier can be improved when the agent containing the tackifier (the first agent and the second agent) is formed. Further, as a result of the above evaluation test, it is understood that the associative tackifier can be blended in either the first agent or the second agent.
