Description

Hair cosmetic composition

The present application is a divisional application of the original application "hair cosmetic composition" filed on date 03/2015 and having application number 201580011673. X.

Technical Field

The present invention relates to a hair cosmetic composition, and more particularly, to a hair cosmetic composition in which a plurality of agents are mixed and foamed by shaking. The hair cosmetic composition of the present invention includes hair dye compositions such as oxidation hair dye compositions, hair bleaching/bleaching compositions, and the like.

Background

In the prior art, there are disclosed hair cosmetic compositions which are foamed by mixing a plurality of agents by shaking. For example, the following patent documents 1 and 2 disclose the following hair cosmetic compositions: it is a hair dye such as a multi-agent type oxidation hair dye or a hair bleach, and the respective agents are mixed and foamed by shaking in a container.

Patent document 2: japanese laid-open patent publication No. 2012 and 106954

However, the above conventional foam-like hair cosmetic product based on the oscillation mixing foaming method has the following problems: as the time after foaming passes, defoaming and the resulting decrease in the quality of the foam are likely to occur, so that the foamed foam cannot be sufficiently maintained continuously. On the other hand, when the agents constituting the hair cosmetic are made highly viscous in advance to suppress defoaming, it is difficult to obtain good foaming in the mixing foaming method by shaking. In addition, in the case of a reagent which has been previously made highly viscous, a so-called "lump" may be generated. In addition, when the hair is foamed by the shaking mixing, the mixing of the plurality of agents may become insufficient, and the hair cosmetic composition as a hair dye may have deteriorated properties such as hair dyeing properties and bleaching properties.

Disclosure of Invention

Therefore, the technical problem to be solved by the present invention is: in the hair cosmetic composition used by mixing and foaming a plurality of agents by shaking, the above-mentioned disadvantages caused by the prior high viscosity of the agents are not accompanied, and the continuous retention of the foam after mixing and foaming is improved.

The inventors of the present application think of the following: the object of the present invention can be achieved if a plurality of agents constituting a hair cosmetic composition such as a hair dye are designed so that viscosity can be increased during mixing/foaming by shaking.

Further, focusing on the fact that an anionic polymer selected from acrylic polymers has a thickening property when it changes from acidic to basic, it has been found that a plurality of reagents can be thickened during mixing/foaming by blending the anionic polymer with an acidic reagent, and the present invention has been completed.

Moreover, the inventors of the present application have obtained the following new findings, which could not be predicted in the common sense of the prior art: when the polyether-modified silicone is blended in a hair cosmetic in the form of foam suitable for hair, the foam quality and the number of foam at the time of foaming of the hair cosmetic can be well maintained during the hair styling process.

(invention 1)

The present invention according to claim 1 is a hair cosmetic composition which is prepared by mixing and foaming a plurality of agents including an acidic agent containing 1 or more anionic polymers selected from acrylic polymers by shaking, wherein the mixture of the plurality of agents is alkaline.

In the present specification, the term "acidic" means a pH of 7 or less, and the term "basic" means a pH exceeding 7. The "anionic polymer selected from acrylic polymers" is an acrylic polymer containing acrylic acid as a monomer and having a larger number of anionic groups (carboxyl groups, sulfo groups, etc.) in a molecule than cationic groups in the same molecule. The polymer increases in tack when changing from an acidic state to a basic state.

According to the invention of claim 1, in the hair cosmetic composition in which a plurality of agents are mixed and foamed by shaking, the plurality of agents include an acidic agent (for example, a 2 nd agent containing an oxidizing agent in an oxidative hair dye, a hair bleaching/bleaching agent), and the acidic agent includes 1 or more anionic polymers selected from acrylic polymers (hereinafter, also referred to as "anionic acrylic polymers"). The anionic acrylic polymer does not exhibit a thickening effect in the acidic agent, and therefore the acidic agent can be easily made to have a low viscosity. Therefore, no lump is generated in the reagents, or insufficient mixing occurs when mixing and foaming a plurality of reagents by shaking.

On the other hand, the hair cosmetic composition of the invention 1 is designed such that each agent containing an acidic agent becomes alkaline after mixing. The anionic acrylic polymer exhibits a thickening effect in a basic state. Thus, the acrylic polymer shows a thickening effect shortly after the various agents are well mixed and foamed by shaking. As a result, in the foam-like hair cosmetic of the mixed foaming system by the oscillation, the foam-like hair cosmetic can maintain the foam-like hair after foaming.

Further, even when 1 or more kinds of acrylic polymers having a large number of cationic groups in the molecule (hereinafter, also referred to as "cationic acrylic polymers") such as dimethyldiallylammonium chloride/acrylic acid copolymer (trade name: Marcort (マーコート)280) are blended in place of the anionic acrylic polymer in the acidic reagent, the above-described effects cannot be obtained.

Preferably, the invention 1 of the present application is characterized in that the acidic reagent contains 1 or more kinds of anionic surfactants.

According to this feature, since the acidic agent contains 1 or more anionic surfactants, a foam-like hair cosmetic composition having good foam quality can be obtained when mixed and foamed by shaking. It is known that anionic surfactants are suitable for foaming in which good foam quality is sought.

If the acidic reagent contains a cationic acrylic polymer, the anionic surfactant is complexed with the cationic acrylic polymer, and therefore foaming with good foam quality by the anionic surfactant is inhibited. However, in the hair cosmetic composition according to the invention of claim 1 of the present application, since the anionic acrylic polymer is blended with the acidic agent, such a disadvantage does not occur.

Further, the invention of claim 1 preferably has a feature that the reagent different from the acidic reagent contains a cationic surfactant or 1 or more kinds of cationic substances selected from cationic polymers.

According to this feature, since the agent other than the acidic agent (for example, the oxidation hair dye, the agent 1 containing an alkaline agent in the hair bleach, or the agent 3 containing no oxidizing agent or alkaline agent) in the hair cosmetic composition contains the cationic surfactant or 1 or more kinds of cationic substances selected from cationic polymers, the touch feeling of the hair using the foam-like hair cosmetic is improved.

Further, since these cationic substances are not blended in an acidic agent containing, for example, hydrogen peroxide, degradation such as decomposition (molecular weight reduction) of the cationic substances by hydrogen peroxide does not occur during storage, and the effect of improving the feel of hair described above can be exhibited.

In addition, when the acidic reagent contains an anionic surfactant and the reagent different from the acidic reagent contains a cationic substance, it is expected that the anionic surfactant and the cationic substance are complexed when these reagents are mixed. There is a fear that the formation of such a complex may "become a cause of clogging of the discharge portion of the container" in the foamed hair cosmetic of an aerosol type or a non-aerosol type. However, the hair cosmetic composition that is mixed and foamed by shaking is not so problematic, and the formation of some degree of complexation can improve the mixability of a plurality of agents.

Preferably, the invention of claim 1 is characterized in that the cationic polymer is polydimethyldimethyldimethyldimethylmethylenepiperidine chloride.

According to this feature, the cationic polymer is polydimethyldimethyldimethylmethylenepiperidine chloride, and therefore has the following effects: the hair conditioner has less adverse effect on foamability than other cationic polymers, and can improve the feel of hair when rinsed.

Further, the invention 1 of the present application preferably has a feature that the plurality of reagents include a reagent containing 1 or more polyether-modified siloxanes.

The hair cosmetic composition which is prepared by mixing and foaming a plurality of agents by shaking has the following effects: when 1 or more polyether-modified silicones are blended in any of the agents, not only the feel of hair is improved, but also the defoaming property as a component for improving the feel of hair is smaller than that of silicones such as general-purpose amino-modified silicones and dimethylsilicone oil, and the quality of foam and the number of foam during the whole hair growth process are easily maintained. Therefore, the effect of the invention 1 can be exerted while having the effect of improving the hair feel by the silicone compound.

Further, the invention 1 of the present application is preferably characterized in that the agent containing a higher alcohol is contained in a plurality of agents, and the polyether-modified siloxane is formulated in the agent containing the higher alcohol.

The present inventors have also found that the following novel effects are also exhibited as the compounding effect of the polyether-modified silicone: the precipitation of higher alcohol related to viscosity, brightness and hair dyeing ability of the hair cosmetic composition is suppressed, and the storage stability is improved. Therefore, according to this feature, when a higher alcohol is blended in the hair cosmetic composition, the precipitation thereof can be suppressed, and the storage stability can be improved.

In addition, when a siloxane other than polyether-modified siloxane is blended, even if the feel effect of the hair is improved, the effect of maintaining the foam retention after foaming (the effect of suppressing defoaming) and the effect of suppressing the precipitation of higher alcohols are not obtained.

Further, the invention 1 of the present application is preferably characterized in that the acidic reagent contains 1 or more kinds of nonionic surfactants.

When 1 or more nonionic surfactants are blended in the acidic agent, the foam quality and foam hardness at the time of foaming by mixing a plurality of agents are further improved, and therefore, the foam retentivity after foaming can be further improved.

Further, the invention of claim 1 preferably has a feature that the acidic reagent contains 1 or more nonionic surfactants having HLB of 10 or more.

According to this feature, in addition to the effect of improving the quality of the foam and the hardness of the foam when a plurality of kinds of foams are mixed and foamed, when a higher alcohol is added to the acidic agent, the precipitation of the higher alcohol can be suppressed, and the storage stability can be improved.

(invention 2)

The invention of claim 2 is a hair cosmetic composition in the form of foam suitable for application to hair, the hair cosmetic composition containing 1 or more polyether-modified silicones.

The effect of the case where 1 or more polyether-modified silicones are contained in a hair cosmetic in which an acidic agent contains an anionic acrylic polymer, a mixture of a plurality of agents is basic, and the plurality of agents are mixed and foamed by shaking has been described in invention 1.

However, as a result of further studies conducted by the present inventors, the following were found: even in a hair cosmetic in which the acidic agent does not contain an anionic acrylic polymer, or even in a hair cosmetic in which foaming is not caused by shaking, or in a hair cosmetic composition which is applied to hair in a foam state only, if 1 or more kinds of polyether-modified silicone are blended, the feel effect of hair can be improved, and the defoaming after foaming of the hair cosmetic can be easily suppressed, and the quality of foam and the amount of foam during the hair styling process can be satisfactorily maintained.

Therefore, according to the invention of claim 2 of the present application, the defoaming of a broad range of hair cosmetic compositions in the form of foam suitable for application to hair can be suppressed after foaming, and the quality and the number of foam during the whole hair can be maintained well.

Further, the polyether-modified silicone is blended, which also has an effect of improving the feel of hair treated with the hair cosmetic.

Further, the invention of claim 2 preferably has the following features: the agent containing polyether-modified siloxane contains a higher alcohol.

As the blending effect of the polyether modified siloxane, the following new effects can be achieved: the precipitation of higher alcohol related to viscosity, brightness and hair dyeing ability of the hair cosmetic composition is suppressed, and the storage stability is improved.

Further, the invention of claim 2 preferably has the following features: the hair cosmetic composition is composed of a plurality of agents, and the plurality of agents are mixed and foamed by shaking.

Among the hair cosmetic compositions of the wide variety of the above-described invention 2, a hair cosmetic composition of the type of "mixing and foaming a plurality of agents by shaking" can be mentioned as one of preferable embodiments. According to this type of hair cosmetic composition, it can be easily foamed by shaking mixing.

Further, the invention of claim 2 preferably has the following features: contains more than 1 nonionic surfactant.

By blending 1 or more nonionic surfactants, the foam quality and foam hardness are further improved, and therefore, the following effects of the invention of claim 2 can be improved: can suppress the defoaming after foaming and can maintain the quality and quantity of foam well during the whole foaming process.

Further, the invention of claim 2 preferably has the following features: contains 1 or more nonionic surfactants having HLB of 10 or more.

When 1 or more nonionic surfactants having an HLB of 10 or more are contained, the effects of suppressing the precipitation of higher alcohols and improving the storage stability thereof are more remarkable.

According to the invention of claim 1 of the present application, in the hair cosmetic composition used by mixing and foaming a plurality of agents by shaking, the maintenance of foam after mixed foaming can be improved without the above-mentioned inconvenience caused by previously increasing the viscosity of the agents.

According to the invention of claim 2 of the present application, in the hair cosmetic composition of a wide variety of types which is applied to hair in the form of foam, defoaming after foaming can be suppressed, and the quality of foam and the number of foam during the whole hair can be favorably maintained.

Group of embodiment 1

The embodiment 1 relates to the embodiment of the hair cosmetic composition according to the invention 1.

[ Mixed foaming based on shaking ]

In the present invention, a plurality of agents constituting the hair cosmetic composition are mixed and foamed by shaking. The mixture may be shaken to foam the mixture after mixing the plurality of reagents, or the mixture may be shaken to simultaneously mix and foam the plurality of reagents.

The "oscillation" is an operation of causing a flow of an agent constituting the hair cosmetic composition, and more preferably an operation of causing a random flow such as turbulence or convection.

The method of oscillation is not particularly limited. From the viewpoint of foaming by a simple operation, it is preferable to include 1 or more selected from the operation of foaming by shaking the container, the operation of foaming by stirring the mixed gas, and the operation of generating a gas by bringing the 1 st reagent into contact with another reagent by stirring. More preferably, the foaming is performed by one operation selected from an operation of shaking the container to foam, an operation of stirring the mixed gas to foam, and an operation of bringing the 1 st reagent into contact with the other reagent by stirring to generate a gas. From the viewpoint of ease of use, the operation of foaming by shaking the container is more preferable.

The "operation of bringing the 1 st reagent into contact with another reagent by stirring to generate a gas" is a concept including the following operations: carbon dioxide is generated from carbonate or the like contained in the 1 st reagent by an acid contained in the other reagent to foam.

An appropriate vessel and a stirring tool can be used in combination with the oscillation method. For example, as disclosed in patent document 1 and international publication No. WO2011/151880, an openable and closable closed container into which a plurality of reagents constituting a hair cosmetic composition can be put and oscillated can be used. Further, for example, as disclosed in patent document 2, a cup-shaped container for charging a plurality of agents constituting the hair cosmetic composition, and a stirring tool in the form of, for example, a bamboo sheet for stirring and foaming the plurality of agents charged into the container can be used.

The foamed hair cosmetic composition can be suitably used by a known method. For example, the foamed hair cosmetic composition may be taken out from the container by a scooping tool such as a glove or a spoon, or the foamed hair cosmetic composition may be poured onto the hair by tilting the container.

Also disclosed are a hair dyeing method, a hair bleaching method and a hair bleaching method using the foam-like hair cosmetic composition prepared by the above method. It is considered that the following advantages are obtained from the viewpoint of the quality of the foam by using a foam having a suitable composition and good shape retention: regarding the number of bubbles, the visual amount was effective and the bubbles were less likely to sag.

Group of embodiment 2

The hair cosmetic composition of embodiment 2 is the same as the hair cosmetic composition of embodiment 1 of the above-described hair cosmetic composition of embodiment 2.

[ Main ingredient of Hair cosmetic composition ]

The hair cosmetic composition according to embodiment 2 contains 1 or more kinds of polyether-modified silicones. Further, it is preferable to contain a nonionic surfactant having HLB of 10 or more. The nonionic surfactant is particularly effective in inhibiting the deposition of a higher alcohol when the hair cosmetic composition contains the higher alcohol.

(polyether-modified siloxane)

The kind and content of the polyether-modified silicone are as described in the section on "polyether-modified silicone" of the hair cosmetic composition of embodiment 1. In the case where the hair cosmetic composition is of a multi-agent type, either agent may contain the polyether-modified silicone. However, since polyether-modified silicone has an effect of improving the feel of hair, an effect of suppressing defoaming after foaming in a hair cosmetic as compared with other silicone, and an effect of suppressing deposition of higher alcohols, it is particularly preferable to add polyether-modified silicone to a hair cosmetic composition of embodiment 2 in the case where the hair cosmetic composition is of a multi-agent type and higher alcohols are added to 1 or more of the agents.

(nonionic surfactant having HLB of 10 or more)

Preferably, the hair cosmetic composition according to embodiment 2 further contains a nonionic surfactant having an HLB of 10 or more.

Examples of the nonionic surfactant having an HLB of 10 or more include POE (5) alkyl (C12-14) ether (HLB of about 10.5), POE (10) stearyl ether (HLB12.4), POE (7) lauryl ether (HLB12.5), POE (9) tridecyl ether (HLB13.3), POE (11) lauryl ether (HLB14.5), POE (15) cetyl ether (HLB14.7), POE (30) behenyl ether (HLB16.1), POE (21) lauryl ether (HLB16.7), POE (30) cetyl ether (HLB16.9), and POE (40) oleyl ether (HLB 17). The above HLB values represent calculated values based on the griffin method.

In the case where the hair cosmetic composition is of a multi-agent type, either agent may contain a nonionic surfactant having an HLB10 of not less than that. However, since this component increases the effect of suppressing the deposition of higher alcohols by polyether-modified silicone, when the hair cosmetic composition of embodiment 2 is of a multi-agent type and higher alcohols are blended in 1 or more of the agents, it is particularly preferable to blend a nonionic surfactant having an HLB10 of not less than that in the agent together with polyether-modified silicone.

[ other formulating ingredients in Hair cosmetic composition ]

The hair cosmetic composition of embodiment 2 can optionally contain, in addition to the above-mentioned components, for example, various surfactants other than the nonionic surfactant having HLB10 or more, and oily components other than the polyether-modified silicone, an oxidizing agent, a basic agent, an anionic or cationic water-soluble polymer, an oxidation dye, a solubilizing agent, a sugar, a preservative, a stabilizer, a pH adjuster, a plant extract, a crude drug extract, a vitamin, a fragrance, an antioxidant, an ultraviolet absorber, a chelating agent, and the like, within a range not to impair the effects of the invention.

The details of these formulation components are the same as those described for the hair cosmetic composition of embodiment 1.

The viscosity can be determined at 60rpm using a No. 1 rotor in the range of 10 to 100 mPas. The viscosity can be determined at 60rpm using a No. 2 rotor in the range of 100 to 500 mPas. The viscosity can be determined at 60rpm using a No. 3 rotor in the range of 500 to 2000 mPas. The viscosity can be determined at 60rpm using a No. 4 rotor in the range of 2000 to 10000 mPas.
