Description

  The present invention relates to a multi-component hair cosmetic. In particular, the present invention relates to a multi-component hair treatment agent (hair cream or the like) suitable for preparation at the time of use.

  Hair creams and hair oils are known as hair treatment agents. Since hair cream is an emulsified type, it is not sticky to the hands during use and has a relatively refreshing feeling when used. Furthermore, the conditioning effect by oil and the replenishment of moisture (moisturizing) ) There is an advantage of having an effect.

  Conventionally, hair creams are blended with surfactants, thickeners (carboxyvinyl polymer, hydroxyethyl cellulose, guar gum, etc.) or higher alcohols (cetanol, etc.) in order to give moderate viscosity and emulsion stability. Yes.

  However, when a surfactant is used, there are safety problems such as the occurrence of skin irritation. When a thickener is used, there is a problem that it takes time to dissolve it, further increases the viscosity, and it is difficult to prepare a uniform cream quickly and easily. In particular, when hair treatment is performed at a beauty salon or the like, rapid preparation and preparation are strongly required. Furthermore, when a higher alcohol is used in a large amount, there is an environmental problem.

  As another method for obtaining the emulsion stability, Patent Document 1 proposes a cosmetic comprising a powder phase, a liquid oil phase, and a liquid aqueous phase. This cosmetic is prepared by storing the above three phases in separate containers and mixing and emulsifying these three phases at the time of use (that is, when trying to use the cosmetic). It is. Thereby, even after long-term (storage) progress, an emulsified form can be formed at the time of use. In other words, long-term emulsification stability is not achieved by blending components (surfactants, etc.) but by the preparation method of preparation at the time of use, so that surfactants and thickeners are blended. It is expected that the amount can be reduced to some extent.

  However, even in this use-prepared cosmetic, in order to obtain sufficient emulsion stability after preparation at the time of use, a surfactant and a thickener (such as carboxyvinyl polymer) must be used. The use of these causes the aforementioned problems.

By the way, in recent years, it has been demanded to prepare and manufacture hair cosmetics individually according to the preference of individual consumers (treatment subjects) with respect to hair quality, hair texture, and the like. However, since conventional hair cosmetics are so-called “ready-made” products, it has been difficult to prepare and manufacture them according to the tastes of individual consumers.
JP2003-206216A.

  In view of the above circumstances, the present invention is excellent in safety, can easily and quickly prepare hair cosmetics at the time of use, has no environmental problems, and can be in an excellent emulsified state even after long-term storage. An object of the present invention is to provide a hair cosmetic (such as a hair treatment agent) that has excellent emulsification stability even after preparation, and can flexibly respond to the tastes of individual consumers.

  In order to solve the above-mentioned problems, the present inventors diligently studied, and as a result, the present invention has been achieved.

That is, the first invention of the present application is a hair cosmetic comprising at least a powder / granular powder / granular phase, a liquid oil phase, and a liquid aqueous phase, wherein the water-swellable clay mineral is contained in the powder / granular phase. Alternatively, a hair cosmetic containing a cationized polymer and a liquid surfactant is provided.

  The second invention of the present application provides the hair cosmetic composition of the first invention of the present application, wherein the water-swellable clay mineral is bentonite and the cationized polymer is an ethyltrimethylammonium methacrylate polymer.

In the third invention of the present application, the liquid surfactant is sorbitan monolaurate, sorbitan monooleate, sorbitan monoisostearate, POE lauryl ether, POE isostearyl ether, POE sorbitan monolaurate, POE sorbitan monooleate, POE palm oil fatty acid sorbitan And the hair cosmetic composition according to the first or second invention of the present invention, which is at least one of coconut oil fatty acid acylglutamate triethanolamine .

  According to the present invention, it is excellent in safety, can easily and quickly prepare hair cosmetics at the time of use, has no environmental problems, can be in an excellent emulsified state even after long-term storage, and even after preparation at the time of use. It is possible to provide hair cosmetics (hair treatment agents and the like) that have excellent emulsification stability and that can flexibly respond to the preferences of individual consumers.

Hereinafter, the best embodiment of the present invention will be described in detail.

Therefore, part or all of the amount of conventional additive components (for example, surfactants, thickeners, higher alcohols, etc.) can be omitted, so that the hair cosmetic composition is excellent in safety and environment. it can.

  Furthermore, when a water-swellable clay mineral is blended, thixotropic properties can be imparted to the hair cosmetic. As a result, the viscosity of the hair cosmetic can be reduced, for example, in the mixing step when the hair cosmetic is prepared and manufactured at the time of use, and also in the hand, so that the mixing operation is quick and easy. It is easy to take in the hand and extends to the hair, making it easy to apply evenly. In addition, the water-swellable clay mineral can be quickly and easily uniformly mixed with the water-based component and / or the oil-based component, and the occurrence of stickiness of the oil agent can be suppressed.

  Furthermore, the present inventor has found that the cationized polymer dissolves in water or the like very quickly among various polymers having a thickening function. Therefore, when a cationized polymer is used, it can be uniformly dissolved very quickly and easily compared to the case of using a conventional thickener, and as a result, the workability of preparing hair cosmetics is greatly increased. Can be improved. Furthermore, by blending the cationized polymer, excellent texture and function (softness, antistatic effect, etc.) can be imparted to the hair.

  The hair cosmetic composition of the present invention includes a liquid aqueous phase. By containing a liquid aqueous phase, it can be set as an emulsified cosmetic (especially O / W type emulsified cosmetic). Furthermore, a desired texture (moisturizing feeling, etc.) can be imparted to the hair.

  The liquid aqueous phase of the present invention is preferably in a liquid form at least at an ambient temperature during preparation. Specifically, the liquid aqueous phase of the present invention is preferably in a liquid form at 0 to 40 (particularly 10 to 30)) ° C. Liquid forms include solutions, emulsions, and dispersions.

As described above, the hair cosmetic composition of the present invention has sufficient viscosity and emulsion stability without necessarily adding a surfactant, a thickener, a higher alcohol, or the like. However, when used in combination with one or more of these additive components, extremely high viscosity and / or emulsion stability can be achieved.

In particular, by incorporating a liquid surfactant in the powder / granular phase , other phase components (such as water) can easily enter the voids in the water-swellable clay mineral or cationized polymer. As a result, it becomes possible to prepare uniform hair cosmetics more quickly and easily. Accordingly, the hair cosmetic composition of the present invention is mixed with a surfactant at room temperature and in the powder / granular phase.

  In the hair cosmetic composition of the present invention, the additive component may be appropriately added to one or more phases of the powder / granular phase, the liquid oil phase, and the liquid aqueous phase, or independent of these phases. It is good also as a phase. The independent phase may be composed of one or more phases.

For example, in the hair cosmetic composition of the present invention, when using a water-swellable clay mineral is preferably you blending a nonionic surfactant and / or anionic surfactants in powder-granular phase, cationized polymer when using, preferably a nonionic surfactant and / or cationic surfactants you formulated into powder, granules phase.

  Furthermore, in the hair cosmetic composition of the present invention, the thickener, the oil component, and the powder / particle component of the additive may be added to the powder / particle phase, for example.

  The hair cosmetic composition of the present invention comprises at least a powder / particle phase, a liquid oil phase, and a liquid aqueous phase. Therefore, depending on individual customers' preference for hair quality and hair texture, the amount and ratio of powder / granular phase, liquid oil phase, and liquid aqueous phase can be freely used at the time of use. Therefore, it is possible to prepare and manufacture a hair cosmetic material that is optimal for the consumer.

  Furthermore, in the hair cosmetic composition of the present invention, the powder / granular phase, the liquid oil phase, and the liquid aqueous phase may each be composed of only one phase or a plurality of phases. For example, by configuring the liquid oil phase from a plurality of phases for each component that imparts a variety of textures, depending on the individual consumers' preference for the texture of the hair, the plurality of phases are appropriately used at the time of use. The necessary texture-imparting component phase can be selected and blended, and as a result, an optimal hair cosmetic for the consumer can be easily prepared and manufactured. For example, the liquid oil phase may contain one or more phases such as a hydrocarbon phase, a fatty acid ester phase, a silicone oil phase, an oil phase, and a fatty acid phase as independent phases.

  The hair cosmetic composition of the present invention can be mixed and prepared at the time of use. As a result, hair cosmetics can be used immediately after mixing and preparation. In that case, since the hair cosmetic composition does not necessarily require very long-term emulsion stability, a very large amount of the liquid oil phase can be blended.

  In the composition (% by weight) of the hair cosmetic of the present invention, the powder / granular phase is 1 to 20 (particularly 3 to 10) and the liquid oil phase is 0.1 to 30 (particularly 3 to 3). 20) The liquid aqueous phase is preferably 40 to 95 (especially 60 to 90).

In the composition (% by weight) of the powder / granular phase according to the present invention, the water-swellable clay mineral is 60 or more and less than 100 (particularly 70 to 90), and the cationized polymer is 50 or more and 100 for the entire powder / granular phase. less (especially 60 to 80), surfactant than 0 40 or less (particularly 5 to 30) are each preferably.

  If the powder / granular phase is less than 1% by weight, a uniform emulsion may not be obtained. On the other hand, if it exceeds 20% by weight, the viscosity becomes too high and the oil and water phases can be mixed uniformly. It may disappear. If the liquid oil phase is less than 1% by weight, it may not be possible to obtain a sufficient texture during use. Conversely, if it exceeds 30% by weight, stickiness may occur when used. If the liquid aqueous phase is less than 40% by weight, the blended powder / granular phase and / or oil phase will increase, and these phases may not be uniformly mixed during use. If it exceeds, the desired texture may not be obtained.

  If the water-swellable clay mineral in the powder / granular phase is less than 60% by weight, the hair cosmetic may not be able to obtain a sufficient viscosity, emulsification form and emulsification stability. When the cationized polymer is less than 50% by weight, the hair cosmetic may not be able to obtain a sufficient viscosity, emulsified form and emulsion stability. When a water-swellable clay mineral and a cationized polymer are used in combination, a uniform treatment agent may not be obtained. If the surfactant exceeds 40% by weight, the entire powder / granular phase may not be able to take powder / granularity, and as a result, the powder phase and other phases may not be mixed uniformly.

  In the hair cosmetic composition of the present invention, the powder / granular phase, the liquid oil phase, the liquid aqueous phase, and the other phase (if any) are preferably filled and stored in separate containers.

  The hair cosmetic composition of the present invention can be prepared at the time of use as follows. That is, first, the powder / granular phase and the liquid oil phase are uniformly mixed. Then, if this mixed phase and a liquid aqueous phase are mixed, a uniform hair cosmetic can be prepared easily and quickly (usually within 3 minutes). Mixing is not necessary, and can be easily performed by, for example, simply putting each phase in a suitable container and shaking the container. That is, according to the present invention, anytime, anywhere, anyone can prepare a hair cosmetic suitable for each person according to their own preference.

  Thus, the hair is treated with the hair cosmetic composition of the present invention prepared at the time of use. If necessary, the treated hair is further treated with another hair cosmetic composition (hair treatment agent, etc.). Also good.

  In the other hair cosmetics, examples of the hair treatment agent include those containing silicone oil (such as methylhydrogenpolysiloxane) and alcohols (such as ethanol). By first treating the hair with the hair cosmetic composition of the present invention and then treating the hair with a treatment agent, the finished touch can be further improved.

[Preparation of hair cream]
Examples 3-5, Reference Examples 1 and 2 , and Comparative Examples 1-6
According to the composition shown in Tables 1 and 2, each compounding component in each phase is uniformly stirred and mixed at room temperature, and each multi-drug formula comprising a powder / granular phase, a liquid oil phase, a liquid aqueous phase, etc. A cosmetic preparation prepared at the time of use was prepared.

  The powder / granular phase was prepared by blending other components with bentonite, xanthan gum, ethyltrimethylammonium methacrylate polymer, sodium polyacrylate, or carboxyvinyl polymer.

Thereafter, at room temperature, first, the powder / granular phase, the liquid oil phase and, if necessary, the additives (PPT, fragrance, etc.) are uniformly stirred and mixed, and then the homogeneous mixed phase and the liquid aqueous phase are mixed. Each hair cream (Examples 3 to 5, Reference Examples 1 and 2 , and Comparative Examples 2 to 6) was prepared by stirring and mixing uniformly. In Comparative Example 1, a hair cream could not be prepared.

[Function and property evaluation test of hair cream]
About each preparation (Examples 3-5, Reference Examples 1 and 2 , and Comparative Examples 1-6) obtained as mentioned above about the emulsification state at the time of mixing preparation, emulsion stability, and uniform mixing workability | operativity The test and evaluation were performed as follows. The evaluation results are shown in Tables 1 and 2.

  “Emulsified state at the time of mixing preparation” was obtained by visually observing the emulsified state of the preparation immediately after mixing preparation. “◎” is “completely emulsified uniformly”, “◯” is “almost uniformly emulsified”, “△” is “partially emulsified”, “×” is “emulsified” "Not done".

  “Emulsification stability” was determined by visually observing the emulsified state of the preparation after the preparation had been mixed and allowed to stand at room temperature for 3 days. "◎" is "completely emulsified uniformly", "○" is "almost uniformly emulsified", "△" is "partially separated into two layers", "x" is " “Two layers are separated”.

  In “homogeneous mixing workability”, “◎” means “all phases could be uniformly mixed very easily and rapidly (within 3 minutes)”, “x” means “xanthan gum, sodium polyacrylate, or carboxyvinyl polymer” It took 5 minutes or more to dissolve the solution, and it was not easy to mix all phases uniformly.

From Tables 1 and 2, the following is clear.
If bentonite or ethyltrimethylammonium methacrylate polymer is blended, an excellent emulsification state and emulsion stability at the time of mixing and preparation can be obtained without using a thickener and a surfactant ( Reference Examples 1 and 2). . On the other hand, when the powder / granular phase is absent, it does not become a cream in the first place (Comparative Example 1).

  In the case of containing bentonite or ethyltrimethylammonium methacrylate polymer and a surfactant, an extremely excellent emulsification state and emulsion stability at the time of mixing preparation can be obtained. Furthermore, the powder / granular phase and the liquid aqueous phase are very easily adapted, and as a result, the entire phase can be mixed very easily and rapidly uniformly (Examples 3, 4, and 5).

  On the other hand, when emulsified only with a thickener, it takes a considerable amount of time to dissolve the thickener, making it difficult to uniformly mix all phases quickly and easily (Comparative Example 2 and 3).

  When emulsified only with a surfactant, sufficient emulsification stability after mixing and preparation (for use) cannot be obtained (Comparative Example 4). Therefore, a large amount of surfactant is required to obtain sufficient emulsification stability, resulting in a safety problem.

  When a thickener and a surfactant are contained, it takes a considerable amount of time to dissolve the thickener, making it difficult to uniformly mix all phases quickly and easily. Furthermore, safety and environmental problems occur due to the use of thickeners and surfactants (Comparative Examples 5 and 6).

[Hair treatment]
First, after applying the hair cream of Example 5 to the hair, an appropriate amount of the treatment agent ¹⁾ was applied to the hair tip, and then rinsed well. As a result, it was possible to further improve the feel of the finish by further treating the hair with the treatment agent.

1) (wt%): methyl hydrogen polysiloxane (3) + ethanol (97).
