Description

  The present invention relates to a hair cosmetic composition, a method for using the same, and a hair cosmetic product. More particularly, the present invention relates to a hair cosmetic composition that is applied to hair by being discharged in a foam form from a non-aerosol foamer container, a method for using the same, a hair cosmetic composition, and a non-aerosol foamer container. The present invention relates to a hair cosmetic product comprising the composition.

  It is known to use hair cosmetics such as hair dyes and hair bleaching agents in a foamy dosage form when used. In general, when these hair cosmetics are used in a foamy dosage form, it is easy to apply evenly and uniformly to the hair, and when using a gel-like or cream-like hair cosmetic that is widely used. The advantage of eliminating the need for hair blocking in the case can be expected.

  Hair cosmetics used in foamy dosage forms can be broadly classified into aerosol types and non-aerosol types. The aerosol type uses a propellant such as a liquefied gas and makes the dosage form foam by forming bubbles using the aerosol. Non-aerosol type, without using a propellant, forms a bubble that takes in air using a pump foamer, squeeze foamer or other non-aerosol foamer container (hereinafter also simply referred to as “former container”), Make the dosage form foamy. A non-aerosol foamer container is preferred from the standpoint that the structure of the container for forming a foamed dosage form is simple and advantageous in terms of cost and that there is no danger during storage and handling.

Patent Document 1 and Patent Document 2 described above disclose an oxidative hair dye composition or a hair dye composition that is used in the form of foam with aerosol. In addition, Patent Document 3 and Patent Document 4 described above disclose hair dyes and the like that are used by foaming the dosage form with a non-aerosol foamer container.

  By the way, the foam-type hair cosmetic discharged from the non-aerosol foamer container has a problem that it is difficult to obtain a good feel of hair. Therefore, for example, two-component hair cosmetics (foam hair dye) constituting the hair cosmetic disclosed in Patent Document 5 and two-pack foam hair dye disclosed in Patent Document 6 Attempts have been made to blend conventionally known cationized polymers as improving components.

  However, when a cationized polymer is blended in the hair cosmetic, based on the increase in the viscosity of the hair cosmetic, (1) it becomes difficult for the hair cosmetic to pass through the mesh of the non-aerosol foamer container net, and the quality is fine and fine. It has been found that there are problems with the discharge foam quality, such as the problem that foam cannot be generated, and (2) the foam quality becomes too strong, resulting in a problem that the foam becomes poorly applied to the hair and difficult to apply to the hair.

  Therefore, the present invention is a hair cosmetic discharged from a non-aerosol foamer container in the form of a foam, and can impart a good feel to the hair and has no defect in the discharged foam quality. Providing this is a problem to be solved.

(Configuration of the first invention)

  In the first invention, “10% by mass or more” means “10% by mass or more when the first agent and the second agent are mixed”. Similarly, in the present specification, a numerical value defining the content of a certain component means “the content at the time of mixing the first agent and the second agent” unless otherwise specified.

  In the present invention, the cationic surfactant that is a polymer is not included in the “cationized polymer” but is included in the “surfactant”. Furthermore, a cationized silicone that is a polymer is not included in the “cationized polymer” but is included in the “silicones”.

(Configuration of the second invention)
The constitution of the second invention of the present application for solving the above problem is that in the hair cosmetic composition according to the first invention, the mass ratio A / B of the content of the component (A) to the content of the component (B) is It is a hair cosmetic composition in the range of 10 to 1000.

(Structure of the sixth invention)
The structure of the sixth invention of the present application for solving the above problems is applied to hair by discharging the hair cosmetic composition described in any of the first to fifth inventions in a foam form from a non-aerosol foamer container. The method of using the hair cosmetic composition.

(Structure of the seventh invention)
The structure of the seventh invention of the present application for solving the above-described problems includes a hair cosmetic composition according to any one of the first to fifth inventions, and a non-letter for discharging the hair cosmetic composition in the form of foam. A hair cosmetic product comprising an aerosol former container.

  According to the first aspect of the present invention, a hair cosmetic that is discharged from a non-aerosol foamer container in the form of a foam, which can impart a good feel to the hair and has no defect in the discharged foam quality. A composition is provided. The reason why such an effect can be obtained can be estimated as follows.

  When (B) component is mix | blended with the hair cosmetics which contain the nonionic surfactant which is (A) component as a foaming agent, (1) Hair cosmetics do not easily pass the net mesh of a non-aerosol foamer container. In this case, fine foam cannot be generated, and (2) the foam quality becomes too strong, resulting in problems with the foam quality, such as foam that is poorly applied to hair and difficult to apply to hair.

  However, when the silicone as component (C) is further blended, the increase in the viscosity of the hair cosmetic is suppressed and the fluidity is improved. As a result, the above problem (1) is eliminated and fine bubbles can be generated. In addition, since the component (C) exhibits a certain defoaming action based on the action of disturbing the arrangement of the surfactants, the above problem (2) is eliminated, and the foam quality that is too strong becomes moderately weak. In addition, since the component (C) is originally a feel improving component, the feel of hair is further improved.

  On the other hand, the component (C) also has a problem that it tends to sag during application of a foam-type hair cosmetic based on the defoaming action described above. However, this problem is solved in a well-balanced manner from the point that the foam quality is strengthened by the component (B) and the point that the nonionic surfactant that is the component (A) is contained in an amount of 10% by mass or more. This is because the component (A) produces a foam that is difficult to defoam and has little irritation, so that 10% by mass or more of the component (A) is defoamed by the component (C) under a small amount of irritation. This is because it is suppressed to an appropriate level.

  In addition, when content of (A) component in hair cosmetics composition is less than 10 mass%, it becomes easy to raise | generate dripping at the time of application of foam-type hair cosmetics.

  As specified in the second invention, the mass ratio A / B of the content of the component (A) to the content of the component (B) is preferably in the range of 10 to 1000. If the A / B is less than 10, the negative action of the component (B) described above may be surfaced and the foam quality may become stronger than necessary, and if the A / B exceeds 1000, the hair feels worse. There is a fear.

  As specified in the third invention, the mass ratio C / B of the content of the component (C) to the content of the component (B) is preferably in the range of 0.01 to 50. If the C / B is less than 0.01, the negative action of the component (B) described above may be surfaced and the discharge foam quality may become stronger than necessary. If the C / B exceeds 50, ) Component and (C) component may be out of balance and defoaming is likely to occur.

  As defined in the fourth invention, the component (B) is preferably at least one selected from cationized polysaccharides excellent in water solubility and polymers and copolymers containing at least a diallyl quaternary ammonium salt as a constituent unit.

  According to the fifth invention, an oxidative hair dye, an acidic hair dye, a hair bleaching agent or a hair decoloring agent, which is a particularly preferred embodiment of the hair cosmetic composition, is provided.

  According to the sixth invention, there is provided an effective method for applying the hair cosmetic composition to the hair by discharging it from the non-aerosol foamer container into a good foam.

  According to the seventh invention, there is provided a simple hair cosmetic product comprising a hair cosmetic composition and a non-aerosol foamer container for discharging the hair cosmetic composition in the form of foam. .
