Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to hair in which a water-in-oil emulsion or a self-emulsifying transparent or milky gel is dispersed in a three-dimensional pattern in a translucent gel base or a transparent gel base. Cosmetics, especially hair cosmetics that have a beautiful appearance, can visually capture an aqueous phase/oil phase/aqueous phase emulsion, have a hair protection effect, and have the effect of imparting excellent gloss and smooth feel to the hair. Regarding.

[Conventional technology]

Conventional hair cosmetics based on translucent gel bases or transparent gel bases include pomades, hair solids also called water-soluble pomades, hair styling gels typified by Dip, and gel shampoos.

These are intended for hair styling and protection, and both have uniform and homogeneous properties. Pomade is a gel-like solid solution or semi-solid oil-based hair styling product that has hair styling and hair protection properties, gives shine to the hair, and can be shaped into the desired hairstyle.

Vegetable pomades have castor oil and wood wax as their main ingredients, while mineral pomades have vaseline and paraffin as their main ingredients, and while they have strong hair styling properties, they are sticky, feel heavy, and are difficult to wash off.

Hair solid is a transparent gel-like water-soluble solid hair styling product, and its main composition is a transparent solubilized gel obtained by reacting a transparent microemulsion with a solubilizing system of three components: a surfactant, an oily substance, and water. Since the amount of surfactant blended is very large compared to the amount of oily ingredients, it is necessary to use a highly safe surfactant. A smooth and smooth lily,
It has a light feel and can be washed off with water.

Hair Styling Gel is a transparent gel-like water-soluble solid hair styling product that contains a gelling agent, a film-forming agent, and water as its main ingredients. Can be washed off. Because it has strong hair styling power, hair tends to get frizzy.

Transparent gel-like shampoo is a hair wash that contains a surfactant as a cleaning base and a gelling agent as its main ingredient, and is convenient for carrying when traveling. 1-Stability-1-Difficult to add oil agents such as treatment ingredients, so long-washed hair is difficult to run through with fingers and lacks suppleness.

[Problem to be solved by the invention]

In recent years, consumers' values regarding cosmetics have diversified, and it is no surprise that hair cosmetics have functions such as protecting the hair, styling the hair, and imparting excellent gloss and smooth texture to the hair. In particular, there has been a growing demand for the aesthetic appearance of M hair cosmetics themselves, which leads to visual pleasure in hair cosmetics.

Furthermore, as technology advances, it has become necessary to provide consumers with easy-to-understand explanations about what cosmetics are made of.

However, all hair cosmetics to date look the same to consumers and it is impossible to tell them apart. Or water-in-oil type (hereinafter referred to as W/○
At present, it is difficult to distinguish from the appearance whether the hair cosmetic is made of an emulsion or not, and what kind of constituent ingredients the hair cosmetic consists of.

Based on these circumstances, it is possible to distinguish between the types of emulsion formulations, and the hair cosmetics have a beautiful appearance, a hair protection effect, and the effect of imparting excellent luster and smooth feel to the hair, making them both pleasant and beautiful to look at. development was desired.

[Means to solve the problem]

As a result of intensive research in order to solve the problem mentioned above, the inventors of the present invention have developed an oil agent that has effects such as protecting hair and imparting excellent luster and smooth feel to the hair using a W/○ type emulsion or It is blended as an oil phase component of a self-emulsifying transparent to milky white gel (hereinafter referred to as self-emulsifying gel). The W/○ type emulsion or self-emulsifying gel containing this oil agent can be dispersed in a three-dimensional pattern in a translucent gel base or a transparent gel base; We have discovered that it is possible to obtain a hair cosmetic that can be blended with an oil agent without reducing the hair's appearance, has a beautiful appearance, has excellent three-dimensional pattern stability, and is recognizable as a W/○/W type double emulsion. The present invention has been completed.

That is, the present invention relates to a hair cosmetic composition comprising a water-in-oil emulsion or a self-emulsifying transparent or milky white gel dispersed in a translucent or transparent gel base in a three-dimensional pattern.

The present invention will be explained in detail below.

First, the substances forming the translucent gel base or transparent gel base (hereinafter collectively referred to as gel base) applied to the present invention include those that are dissolved or dispersed in water and exhibit a viscosity above a certain level; It exhibits a certain degree of viscosity or more when neutralized with an alkali or the like, and can be a natural or synthetic water-soluble polymer.

In addition, inorganic gelling agents such as magnesium silicate can also be used.

A gel base is obtained by first dissolving or dispersing these water-soluble polymers or inorganic gelling agents in water, and then adding and blending the various necessary components described below. This gel base has a viscosity necessary to stably hold the W10 type emulsion described below, and its viscosity is 15.0
00 centipoise (hereinafter referred to as CP) or more, preferably 50.

It is more than ooocp. The upper limit of the viscosity of this gel base is not necessarily limited as long as it can be filled. Note that the above-mentioned water-soluble polymers, etc. have different viscosity characteristics when dissolved and dispersed in water, so the viscosity can be adjusted appropriately by adjusting the concentration or mixing two or more types of water-soluble polymers, etc. be done.

Depending on the purpose of the hair cosmetic, water-soluble ingredients used in cosmetics can be blended into the gel base, so that the gel base itself can be used as a hair cosmetic for hair styling and protection. It can be made into a useful product with excellent effects. These various hair cosmetic ingredients include, for example, polyhydric alcohols, monosaccharides, sugars such as polysaccharides, amino acids, water-soluble vitamins, humectants, preservatives, ethanol, surfactants, and water-soluble ultraviolet rays. Absorbents, etc.

Furthermore, when using an oil-based dispersion, dissolution base, or surfactant, it is also possible to add various oil-soluble components such as oil-soluble vitamins, ultraviolet absorbers, and fragrances. In this case, it may become a translucent gel base. A W10 type emulsion dispersed in a three-dimensional pattern in a translucent gel base also has aesthetic properties and forms a beautiful pattern.

The gel base may be colorless or colored.

The colorant used in the gel base is preferably a water-soluble colorant, such as water-soluble tar pigments such as Red No. 2, Yellow No. 4, Yellow No. 5, or water-soluble natural pigments such as vitamin B1□, shikonin, copper chlorophyllin sodium, etc. can be mentioned.

Examples include tar pigments such as No. 49, Red No. 205, and Blue No. 1, natural pigments such as laccaic acid, carminic acid, and guaiazulene, and colored synthetic resins such as polyethylene and polyethylene phthalate.

These colorants can be applied as they are or after having been previously treated to make them water-wettable with silicone oil or the like. Although the amount of the colorant may vary depending on the intended dosage form and the type of colorant used, it is generally 30% by weight or less and 0.001% by weight or more based on the entire W/○ type emulsion. Although it can be applied within a range of colorants, it is also possible to prepare it as appropriate by mixing two or more of the above colorants.

The oil phase components of the self-emulsifying gel include hydrocarbons, triglycerides, higher esters, higher alcohols, higher fatty acids, silicone oils, silicone resins (polymer silicones), antioxidants, and ultraviolet rays. It consists of absorbents, preservatives, etc., and the aqueous phase components include ethanol, polyhydric alcohols, humectants, water-soluble vitamins, amino acids, sugars such as monosaccharides and polysaccharides, preservatives, and surfactants. It consists of various agents, each of which is commonly used in cosmetics.

This self-emulsifying gel is made by selecting these oil phase components and water phase components according to the purpose of the cosmetic, and gradually adding the same dissolved and mixed oil phase components into the dissolved and mixed water phase components while stirring. In addition, it is manufactured. This self-emulsifying gel itself is useful as a polish and hair treatment agent.

The ratio of oil phase components to the entire self-emulsifying gel is 5 to 95%.
Weight%.

This self-emulsifying gel can also be colored to enhance its appearance. Examples of colorants include colorants commonly used in cosmetics, such as yellow iron oxide, red iron oxide, ultramarine blue, chromium oxide, titanium oxide, mica titanium, and other inorganic pigments, Red No. 204, Red No. 205, and Blue. Examples include tar pigments such as No. 1, natural pigments such as laccaic acid, carminic acid, and guaiazulene, and colored synthetic resins such as polyethylene and polyethylene phthalate.

These colorants can be applied as they are or after having been previously treated to make them water-wettable with silicone oil or the like. Although the amount of the colorant may vary depending on the intended dosage form and the type of colorant used, it is generally 30% by weight or less and 0.00↓% by weight or more based on the entire self-emulsifying gel. Although the coloring agent may be applied within a certain range, it is also possible to adjust it appropriately by mixing two or more of the above coloring agents.

In order to disperse these W/○ type emulsions or self-emulsifying gels in the gel base in a three-dimensional pattern, the W/○ type emulsions or self-emulsifying gels and the gel base are simultaneously filled (inner phase: The hair makeup of the present invention, in which the W10 type emulsion or self-emulsifying gel presents a three-dimensional pattern in the gel base by continuously filling a container with a W/○ type emulsion or self-emulsifying gel (external phase gel base) get a fee.

For example, W1 in the filling nozzle for dispensing the gel base.
A multi-filling nozzle with a built-in sub-nozzle for supplying type 0 emulsion or self-emulsifying gel allows transparent gel base and W/○ type emulsion or self-emulsifying gel to rotate or move in a fixed direction. By simultaneously filling the gel base into a container, it is possible to produce a hair cosmetic in which a W/○ type emulsion or a self-emulsifying gel is dispersed in a three-dimensional pattern in a gel base. At this time, by combining the size and rotation speed of each nozzle or the rotation speed of the container, it is possible to draw various three-dimensional patterns. Here, the amount of the W/○ type emulsion or self-emulsifying gel in the hair cosmetic of the present invention is determined based on the purpose of the hair cosmetic.
Although it can be set arbitrarily depending on the purpose, for the sake of aesthetic appearance, a range of ◯, 0.5 mm to 10 weight is preferred.

If it is less than 0.1% by weight or exceeds ]O weight, it becomes difficult to obtain an aesthetic three-dimensional pattern. Note that the three-dimensional pattern referred to here refers to a form formed by a continuous phase or an intermittent phase of a W10 type emulsion or a self-emulsifying gel, and refers to, for example, a geometric pattern such as a spiral shape.

The hair cosmetic of the present invention obtained as described above has a stable three-dimensional pattern and an aesthetic appearance, and when used, a synergistic combination of a gel base and a W/○ emulsion or a self-emulsifying gel is used. It can provide the desired hair protection effect, give the hair excellent gloss and smooth feel, and provide hair styling ability.

The hair cosmetics thus proposed by the present invention include, for example, hair styling gels, glossy gels, hair solids (aqueous pomades), treatments, shampoos, conditioners, and the like.

[Effect]

In the present invention, since the W10 emulsion or self-emulsifying gel is three-dimensionally dispersed in the gel base, the three-dimensional pattern is stabilized. This three-dimensional pattern can be changed arbitrarily, and the ingredients of the gel base and the W/○ type emulsion or self-emulsifying gel can also be changed, so the beauty of the pattern can be changed in various ways and can be tailored to suit the purpose. It can be used as a hair cosmetic. Furthermore, the three-dimensional pattern of the hair cosmetic is stable and beautiful even during use.
