Hair cosmetic composition, method of use thereof, and hair cosmetic

The present invention relates to a hair cosmetic composition, a method of using the same, and a hair cosmetic. More specifically, the present invention relates to a hair cosmetic composition which can be discharged from a non-aerosol molded container in a foam form and applied to hair, a method of using the same, and a composition comprising the hair cosmetic composition and a non-aerosol molded container. Hair cosmetics.

A hair cosmetic such as a hair dye or a hair bleaching agent is known to be used in a foamed dosage form at the time of use. In general, when these hair cosmetics are used in a foamy dosage form, the advantage described later can be expected: it is easy to apply evenly on the hair without stains, and it can be eliminated when using a widely used gel-like or creamy hair cosmetic. The trouble of hair agglomeration and the like.

Hair cosmetics for use in a foamy dosage form can be broadly classified into an aerosol type and a non-aerosol type. For the aerosol type, a propellant such as a liquefied gas is used, and the formulation is made into a foam by the formation of bubbles using an aerosol. For the non-aerosol type, a propellant is not used, and other non-aerosol molded containers (hereinafter also simply referred to as "formed containers") using a pumping device (Pump Foamer) or an extrusion molding device are used to form air-collecting bubbles. The dosage form is foamed. It is preferable to use a non-aerosol molded container from the viewpoints of a simple configuration of the container for foaming the dosage form, a cost advantage, and a risk of no storage or handling.

The foam-type hair cosmetic which can be discharged from the non-aerosol molded container has various advantages as described above, but on the other hand, there is a problem that it is difficult to obtain a good touch (feel) of the hair. Therefore, as a two-form hair cosmetic disclosed in the above-mentioned Patent Document 5, as a component for improving the sense of touch, it is attempted to blend a currently known anthrone or a double-formulation foam as described in the above-mentioned Patent Documents 6 and 7. Hair dyes, as a tactile-improving ingredient, attempt to incorporate the currently known cationized polymers.

However, anthrones have a defoaming action, and therefore, when they are blended in a foamy formulation of a hair cosmetic, there is a problem in that the effervescent is easily dripped when applied to hair. In addition, when the cationized polymer is blended, the viscosity of the hair cosmetic is increased, so there is (1) the hair cosmetic is difficult to pass through the mesh of the mesh of the non-aerosol-forming container, and the fine foam having a fine texture cannot be formed, and (2) the foam The quality is too strong, and the affinity for hair is poor, forming a problem that it is difficult to apply the discharged foam on the hair.

In order to solve the above problems, the hairdressing cosmetic composition according to any one of claims 7 to 11 of the present application, and the hair cosmetic composition for use in the hair cosmetic composition It is composed of a non-aerosol molded container that is discharged in a foam form.

According to the first item of the patent application range, the effects described later can be expected. In other words, the hair cosmetic which is discharged from the non-aerosol molded container in the form of a foamed form contains the indolinone as the component (B) and contains 10% by mass or more of the nonionic surfactant as the component (A). Foaming agent. The component (A) forms a foam which is particularly difficult to defoam even in various surfactants, and thus can counteract the defoaming action of anthrone. As a result, the hair cosmetic as claimed in claim 1 does not cause dripping when applied to hair caused by anthrone. Further, the component (A) has a feature that the irritancy is particularly small even in various surfactants.

On the other hand, the anthrone (1) has a property of suppressing an increase in viscosity of the hair cosmetic and improving fluidity, and (2) has an effect of disturbing the alignment of the surfactant in the foam. Therefore, even if it is assumed that the hair cosmetic is further blended with the cationized polymer as in the first aspect of the patent application, the viscosity of the hair cosmetic is increased by the blending, and may be due to the nature of the above (1) of the fluorenone. inhibition. In addition, the problem that "the viscosity of the hair cosmetic is increased, the texture is fine and the quality of the foam cannot be generated", and the "the foam is too strong to be applied to the hair" caused by the blending of the cationized polymer is also caused by the problem. The properties of the above ketones (2) are suppressed.

Therefore, according to the first aspect of the patent application, it is possible to provide a hair cosmetic which is discharged from a non-aerosol molded container in a foam form, which imparts a good touch to the hair, and does not generate the aforementioned various discharge bubbles when applied to the hair. Quality problem.

In addition, when the content of the component (A) in the hair cosmetic composition is less than 10% by mass, when a foam-type hair cosmetic is applied, various problems of discharging the foam are apt to occur.

According to the second aspect of the patent application, it is possible to provide a hair cosmetic which is discharged from a non-aerosol molded container in a foam form, which imparts a good touch to the hair, and which is particularly excellent in preventing dripping when applied to hair.

In the second aspect of the patent application, the first reason for obtaining the above effects is to contain more than 10% by mass of a nonionic surfactant. The nonionic surfactant has the characteristics of generating a foam which is difficult to defoam, and is a surfactant, and has less irritation. By blending in an amount of more than 10% by mass, it is possible to sufficiently generate defoaming and no dripping. Bubble.

In view of the remarkable effect of the second item of the patent application, "more than 10% by mass of the nonionic surfactant" is particularly preferable, and is, for example, 10.1% by mass or more, 10.5% by mass or more, or 11% by mass or more. It is especially preferred that the content of the nonionic surfactant is as shown in item 3 of the patent application.

In the second aspect of the patent application, the second reason for obtaining the above effects is to contain polyoxyethylene-modified anthrone as an anthrone. Polyoxyethylene modified anthrone has a certain degree of water solubility compared with other anthrones and exhibits a part of interfacial activity. As a result, not only the hair is imparted with good tactile sensation, but also the synergistic action with the aforementioned nonionic surfactant can effectively prevent dripping when applied to hair.

According to the third aspect of the patent application, the content of the nonionic surfactant as the component (A) is in the range of 11% by mass to 25% by mass, and the above-mentioned item 1 of the patent application can be remarkably improved. effect. When the content of the component (A) exceeds 25% by mass, the effect of the invention is saturated.

According to the fourth aspect of the patent application, an oxidative hair dye, an acid hair dye, a hair bleaching agent or a hair dyeing agent which is a particularly preferred embodiment of the hair cosmetic composition can be provided.

According to the fifth aspect of the patent application, an effective method for discharging the hair cosmetic composition from a non-aerosol molded container in a good foam form and applying it to the hair can be provided.

According to the sixth aspect of the patent application, a simple hair cosmetic product comprising a hair cosmetic composition and a non-aerosol molded container for discharging the hair cosmetic composition in a foam form can be provided.

According to the seventh aspect of the patent application, it is possible to provide a hair cosmetic which is discharged from a non-aerosol molded container in a foamy dosage form, which imparts a good touch to the hair, and "produces a fine texture of high quality foam", or "easy to apply" The effect of discharging the foam on the hair is particularly excellent. The reason why such an effect can be obtained is also described in the first item of the patent application, and in detail, it can be estimated as follows.

When the component (C) is blended in a hair cosmetic containing a nonionic surfactant as the component (A) as a foaming agent, there is usually a disadvantage of discharging the foam, which is disadvantageous in that (a) hair cosmetics are difficult By the mesh of the mesh of the non-aerosol molded container, fine foam cannot be formed, (b) the foam is too strong, and the affinity for hair is poor, and foam which is difficult to apply to the hair is formed.

However, when the indolinone as the component (B) is blended, the viscosity of the hair cosmetic can be suppressed from increasing, and the fluidity can be improved. As a result, the disadvantage of the above (a) can be eliminated, and a fine foam can be formed. Further, the component (B) exhibits a certain defoaming action based on the action of disturbing the alignment of the surfactant, thereby eliminating the disadvantage of the above (b), and the excessively strong foam is moderately weak. Further, since the component (B) is originally a tactile enhancing component, the touch of the hair is further improved.

On the other hand, the component (B) is based on the aforementioned defoaming action, and there is a problem that it is liable to cause dripping when applied to a hair cosmetic of a foam form. However, this problem is balanced from the viewpoint of enhancing the foaming property by the component (C) and containing 10% by mass or more of the nonionic surfactant as the component (A), and is easily eliminated. This is because the (A) component generates a foam which is difficult to defoam and has less irritation. Therefore, the component (A) of 10% by mass or more has a small amount of stimulation, and also suppresses the defoaming action of the component (B). The standard.

As defined in the eighth aspect of the patent application, the mass ratio of the content of the component (A) to the content of the component (C) is preferably in the range of 10 to 1,000. When A/C is less than 10, the negative action of the above component (C) is surfaced, and there is a possibility that the discharged foam becomes strong to the extent required, and if A/C exceeds 1,000, the tactile sensation of the hair may be deteriorated.

As defined in the ninth aspect of the patent application, the mass ratio of the component (B) to the content of the component (C) is preferably in the range of 0.01 to 50. When B/C is less than 0.01, the negative action of the above component (C) is surfaced, and there is a possibility that the discharged foam becomes strong to the extent required, and if B/C exceeds 50, the balance of the (C) component and the (B) component It is possible to destroy and become easy to defoam.

As defined in claim 10, the component (C) is selected from the group consisting of a cationized polysaccharide excellent in water solubility, and a polymer and a copolymer containing a diallyl quaternary ammonium salt as a constituent unit. At least one of them is preferred.

According to the eleventh aspect of the patent application, an oxidative hair dye, an acid hair dye, a hair bleaching agent or a hair decoloring agent which is a particularly preferred embodiment of the hair cosmetic composition can be provided.

According to item 12 of the patent application, an effective method of discharging a hair cosmetic composition from a non-aerosol molded container in a good foam form and applying it to the hair can be provided.

According to the thirteenth aspect of the patent application, a simple hair cosmetic product comprising a hair cosmetic composition and a non-aerosol molded container for discharging the hair cosmetic composition in a foam form can be provided.
