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 following advantages can be expected: it is easy to apply uniformly on the hair without stains, and it can be eliminated when using a widely used gel-like or creamy hair cosmetic. The hair is agglomerated and so on.

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.

It is composed of a non-aerosol molded container that is discharged in a foam form.

According to the first aspect of the patent application, a hair cosmetic composition can be provided as a hair dye or a hair bleaching agent, which is discharged from a non-aerosol molded container in a foam form, wherein the hair can be imparted with good lightness and excellent hair dyeing. And there is no dripping when applied to the hair. The reason for obtaining such an effect is presumed to be the reason as described below.

When a higher alcohol is blended in a non-aerosol type hair cosmetic having a surfactant as a foaming agent, improvement in brightness or dyeing of hair can be expected, but as described above, there are disadvantages in that an emulsion type is formed. It is difficult to obtain a good foam, and it is easy to cause dripping when applied to hair.

However, in the hair cosmetic of the first aspect of the patent application, as the component (B), the component (B1) is blended, and the component (B1) is a temperature which is usually used as a hair cosmetic, and is assumed to be a temperature of 25 °C. A higher alcohol in the form of a liquid. Compared with the higher alcohol which is solid or pasty at 25 ° C, this higher alcohol is not inferior to the improvement of the brightness or dyeing of the hair. Secondly, since it is liquid, it is easy to discharge. A formulation of a melting system.

Then, even if the high-grade awake which is liquid at 25 ° C is blended, there is no possibility that the hair cosmetic may be dripped due to its defoaming effect, but in this case, the hair cosmetic of the first aspect of the patent application contains 10 A mass% or more of a nonionic surfactant as the component (A) is used as a foaming agent.

The component (A) has a property of being able to generate a foam which is difficult to defoam and has less irritation. Therefore, by blending 10% by mass or more of the component (A), it is possible to form a sufficient amount of foam on the basis of less irritation, and it is possible to form a foam which is difficult to defoam against the defoaming action of the component (B1). By the action of the above components (A) and (B1), it is possible to impart good lightness to the hair, and to excellent dyeing of the hair, and to form a hair cosmetic which does not drip when applied to hair.

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

The higher alcohol as the component (B1) preferably has a special effect by a branched type higher alcohol as defined in the second aspect of the patent application.

According to the third 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 item 4 of the scope of the patent application, an effective method of 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 fifth 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 sixth aspect of the patent application, the following effects can be expected on the premise of blending the component (B2) having a specific effect as a linear type higher alcohol: myristyl alcohol. That is, it is possible to provide a hair cosmetic which is constituted as a hair dye or a hair bleaching agent, and is discharged from a non-aerosol molded container in a foam form, and is excellent in dispersibility of the myristyl alcohol as the component (B2), and imparts good light to the hair. Brightness and hair dyeing are also excellent. The reason for obtaining such an effect is presumed to be the reason as described below.

As described above, when a non-aerosol type hair cosmetic having a surfactant as a foaming agent is blended as a linear higher alcohol, but a short alkyl chain myristyl alcohol, the brightness of the hair can be improved. Alternatively, it may be a preparation of a solubilized system or a dispersion system, but it is difficult to disperse the myristyl alcohol well, and it is difficult to obtain a good foam.

However, in the hair cosmetic of the sixth aspect of the patent application, as the (B2) component, the non-ion is added as the (A1) component, and the number of EOs is relatively small (relatively, the lipophilicity is strong). a POE alkyl ether of a surfactant, and a POE alkyl ether as a nonionic surfactant as a (A2) component having a large EO number (relatively, hydrophilic), and further blended as (B1) a higher alcohol which is liquid at 25 ° C. Therefore, the dispersibility of myristyl in the preparation of the solubilized system or the dispersion system is improved.

Further, the two components (A1) and (A2), which are nonionic surfactants, generally have a property of being less irritating and producing a foam which is difficult to defoam. Therefore, the two components (A1) and (A2) can counteract the fearful defoaming action which is the opposite of the above-mentioned preferred action of the (B1) component of the higher alcohol, and form a foam which is difficult to defoam.

According to the seventh aspect of the patent application, since the component (A1) and the component (A2) are linear POE alkyl ethers, the effects of the components (A1) and (A2) described above can be particularly preferably exhibited.

According to the eighth aspect of the patent application, the component (A1) and the component (A2) are each limited to a substance having an HLB value within a specific range, so that the effects of the above (A1) component and (A2) component can be more preferably exerted. .

According to the ninth 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 tenth aspect of the patent application, an effective method of 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 eleventh 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.

(oxidized hair dye)

The oxidative hair dye includes a first preparation containing a basic substance and an oxidative dye, and a second preparation containing an oxidizing agent, which decomposes the melanin of the hair and performs hair dyeing by oxidative polymerization of an oxidative dye produced by the oxidizing agent. Oxidative dyes are classified as dye intermediates and couplers. Instead of an oxidative dye, a direct dye such as a basic dye, a nitro dye, a natural dye, a disperse dye or the like may be blended.

The content of the oxidizing agent in the second preparation is preferably from 0.1 to 10.0% by mass, more preferably from 0.5 to 8.0% by mass. When the content of the oxidizing agent is less than 0.1% by mass, it may be difficult to sufficiently carry out oxidative polymerization of the oxidative dye. When the content of the oxidizing agent exceeds 10.0% by mass, the hair may be easily damaged.

(acid dyed hair)
