Description

Hair cosmetic composition

The present invention relates to a hair cosmetic composition, and more particularly to a hair cosmetic composition which is mixed and foamed by vibrating a plurality of agents. The hair cosmetic composition of the present invention includes a hair dye composition such as an oxidative hair dye composition or a hair bleaching/decoloring agent composition.

In the past, a hair cosmetic composition which is mixed and foamed by vibrating a plurality of chemicals has been proposed. For example, Patent Document 1 and Patent Document 2 propose a hair cosmetic composition, which is a hair dye such as a plurality of pharmaceutical oxidative hair dyes or hair bleaching agents, and vibrates the respective chemicals in a container to mix and foam. .

Patent Document 2: Japanese Laid-Open Patent Publication No. 2012-106954

In addition, the foam-like hair cosmetic which has been mixed and foamed by vibration in the above-described manner is defoamed over time after foaming, so that foaming property is likely to be lowered, and there is a problem that the foam retaining property after foaming is insufficient. If the agent constituting the hair cosmetic is to be highly viscous in advance and the defoaming is suppressed, it is difficult to foam well by mixing and foaming by vibration. Moreover, the drug having a high viscosity in advance has a so-called "caking". Further, when the foaming is mixed by vibration, the mixing of the plurality of chemicals is insufficient, and the hair dyeing property and the decoloring property of the hair cosmetic composition as the hair dye are likely to be lowered.

Here, the technical problem to be solved by the present invention is as follows: in the hair cosmetic composition used for mixing and foaming with a plurality of vibrating agents, there is no such problem that the drug is previously highly viscous, and Improve the bubble retention after mixing and foaming.

The inventors of the present invention have been able to solve the problem of the present invention by designing a method in which a plurality of chemicals constituting a hair cosmetic composition such as a hair dye are thickened by mixing and foaming by vibration.

Therefore, attention is paid to the characteristic that the anionic polymer selected from the acrylic polymer is tackified from acidic to basic, and is found in acid. The present invention can be accomplished by blending the anionic polymer with the anionic polymer to increase the viscosity of the plurality of agents during mixing and foaming.

The inventors of the present invention have further discovered new knowledge that cannot be predicted by conventional technical knowledge. If the polyether-modified polyfluorene is blended in a hair cosmetic used for hair in a bubble form, the foam of the hair cosmetic is foamed. The amount of foam can be well maintained in hair treatment.

(first invention)

According to a first aspect of the invention, a hair cosmetic composition is obtained by mixing a foam by a plurality of vibrating agents, wherein the plurality of chemicals contain an acidic agent containing an anionic polymer selected from an acrylic polymer. More than this, and the mixture of the plurality of agents becomes alkaline.

In the present specification, "acidic" means that the pH is 7 or less, and "alkaline" means that the pH exceeds 7. In addition, the "anionic polymer selected from the acrylic polymer" refers to an acrylic acid containing a monomer, and the number of intramolecular anionic groups (carboxyl groups, sulfo groups, etc.) is larger than the number of cationic groups in the same molecule. More acrylic polymers. When the polymer changes from acidic to basic, the viscosity increases.

According to the first invention, the foamed hair is mixed by vibrating the plurality of chemicals In the cosmetic composition, the plurality of agents include an acidic agent (for example, an oxidative hair dye or a second agent containing an oxidizing agent in a hair bleaching/decoloring agent), and the acidic agent contains an anionic polymerization selected from an acrylic polymer. One or more kinds of the materials (hereinafter referred to as "anionic acrylic polymer"). The anionic acrylic polymer does not exhibit viscosity-increasing effect in the acidic agent, so the acidic agent can easily become a low viscosity. Therefore, there is no possibility that the agglomerates are formed in the drug or the mixture is insufficiently mixed by foaming the plurality of agents.

On the other hand, the hair cosmetic composition of the first aspect is designed to be alkaline after being mixed with each agent containing an acidic agent. Thus, the anionic acrylic polymer exhibits a tackifying effect under alkaline conditions. Therefore, the acrylic polymer exhibits a viscosity-increasing effect after the plurality of agents are well mixed and foamed by vibration. As a result, in the foam-like hair cosmetic in which the foaming is mixed by vibration, the bubble retention after foaming can be ensured.

Further, even in an acidic agent, an acrylic polymer having a large amount of intramolecular cationic groups such as dimethyldipropenyl ammonium chloride/acrylic acid copolymer (trade name: Merquat 280) (hereinafter referred to as "cationic property" is blended. The above effects cannot be obtained by substituting an anionic acrylic polymer for one or more kinds of acrylic polymers.

Furthermore, the first invention of the present invention preferably has the following characteristics: an acidic drug The agent contains one or more kinds of an anionic surfactant.

According to this feature, since the acidic agent contains one or more kinds of anionic surfactants, it is possible to obtain a foam-like hair cosmetic composition which can be obtained by mixing and foaming by vibration. It is known that an anionic surfactant is suitable for foaming of good foam.

Further, when the acidic agent contains a cationic acrylic polymer, the anionic surfactant forms a complex with the cationic acrylic polymer, which inhibits foaming of a good foam based on the anionic surfactant. However, in the hair cosmetic composition of the first invention of the present invention, the acidic agent is blended with the anionic acrylic polymer, so that such a problem does not occur.

Further, in the first aspect of the invention, it is preferable that the agent different from the acidic agent contains one or more kinds of cationic substances selected from the cationic surfactant or the cationic polymer.

According to this feature, a drug different from an acidic agent in a hair cosmetic composition (for example, an oxidative hair dye, a first agent containing an alkali agent in a hair bleaching agent, or a third agent containing no oxidizing agent or an alkali agent) is contained. Since one or more kinds of cationic substances are selected from the cationic surfactant or the cationic polymer, the feeling of using the hair of the foamed hair cosmetic is good.

Thus, the cationic materials are not blended, for example, with peroxygen. Since the acidic chemical agent is hydrogenated, deterioration of the cationic substance due to decomposition of hydrogen peroxide (low molecular weight) due to hydrogen peroxide does not occur during storage, and the above-described hair feeling improvement effect can be exhibited.

Further, when the acidic agent contains an anionic surfactant and the agent different from the acidic agent contains a cationic substance, when the agents are mixed, it is expected that the anionic surfactant and the cationic substance form a complex. In the foam-like hair cosmetic type of the aerosol foaming type or the non-aerosol foaming type, the formation of such a composite is likely to cause "cause of the clogging of the discharge portion of the foaming container". However, there is no particular problem in the hair cosmetic which is mixed and foamed by vibration, and the formation of a certain degree of the composite system can improve the mixing property of the plurality of pharmaceutical agents.

Further, in the first invention of the present invention, it is preferable that the cationic polymer is a polydimethylamethylene piperidinium salt.

According to this feature, since the cationic polymer is a poly(dimethylamethylene piperidinium) chloride, it does not adversely affect the foaming property as compared with other cationic polymers, and has an effect of improving the feeling of feeling during rinsing.

Further, in the first invention of the present invention, it is preferable that the pharmaceutical agent contains one or more kinds of chemicals containing polyether-modified polyfluorene.

Composition of a mixed hair cosmetic composition by vibrating a plurality of agents When one or more of the polyether-modified polyfluorenes are blended in the arbitrary agent, not only the feeling of the hair can be favorably improved, but also the amine-based modified polymerization which is generally used as a hair-sensing enhancing component. In the case of polyoxymethylene such as deuterium or sputum, the defoaming property is small, and the effect of easily maintaining the foam and the amount of foam in the hair treatment can be exhibited. Therefore, the hair sensation effect can be improved by the polyoxygen compound, and the effects of the first invention can be further exerted.

Further, in the first invention of the present invention, it is preferable that the pharmaceutical agent contains a higher alcohol-containing agent, and the polyether-modified polyoxymethylene is blended in the above-mentioned higher alcohol-containing drug.

The higher alcohol system is related to the viscosity, lightness and hair dyeing power of the hair cosmetic composition. The inventors of the present invention found that the blended polyether modified polyfluorene oxygen has a novel property of suppressing the precipitation of the higher alcohol and improving the preservation stability. efficacy. Therefore, with this feature, in the case where the hair cosmetic composition is blended with a higher alcohol, precipitation of higher alcohol can be suppressed and storage stability can be improved.

Further, when the polyether is modified with a polyfluorene oxide other than polyoxyl oxide, the effect of improving the hair feel can be obtained, but the effect of maintaining the retention of the bubble after foaming (the effect of suppressing the defoaming property), or It inhibits the effect of higher alcohol precipitation.

The first invention of the present invention further preferably has the following characteristics: an acidic agent One or more kinds of nonionic surfactants are contained.

When one or more kinds of nonionic surfactants are blended in the acidic agent, the foam quality and the foam hardness of the plurality of agents during the mixed foaming can be further improved, so that the bubble retainability after foaming can be further improved.

In the first aspect of the invention, it is preferable that the acidic agent contains one or more kinds of nonionic surfactants having an HLB of 10 or more.

According to this feature, the effect of improving the hardness of the foam and the foam at the time of the plural mixed foaming can be suppressed, and in the case where the acidic agent is blended with the higher alcohol, the precipitation of the higher alcohol can be suppressed and the storage stability can be improved.

(second invention)

The acidic agent contains an anionic acrylic polymer, and the mixture of the plurality of agents is alkaline, and the effect of the polyether-modified polyoxyl oxide in the hair cosmetic which is mixed and foamed by the vibration of the plurality of agents is one or more. It is as described in the first invention.

On the other hand, the inventors of the present invention further studied and found that even in a hair cosmetic which does not contain an anionic acrylic polymer in an acidic drug, or even in a hair cosmetic other than a plural formulation, or even in In the hair cosmetic which is not pulverized by vibration, if one or more types of polyether-modified polyfluorene are blended in the hair cosmetic composition which can be applied as a foam to the hair, the hair feel can be improved. It is easy to suppress the defoaming of the hair cosmetic after foaming, and the foam and the amount of foam can be favorably maintained in the hair treatment.

Therefore, according to the second aspect of the invention, it is possible to suppress defoaming after foaming in a hair cosmetic composition which is used in a wide variety of hairs as a foam, and to maintain the foam quality and the amount of foam in the hair treatment favorably.
