[Problem to be solved by the invention]

In recent years, consumers' sense of value regarding cosmetics has diversified, and it is natural for cosmetics to have functions such as makeup effects and skin care effects, and it also leads to visual enjoyment when applying makeup. The aesthetic appearance of cosmetics itself has also come to be required.

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

However, the O/W type emulsion as mentioned above, W10
Type emulsions, W/O/W type emulsions, etc. all look the same to consumers, and it is impossible to tell them apart, especially W10/W type emulsion and O/W type emulsion. Currently, there is no difference in appearance from the cosmetics, and it is difficult to distinguish which type of cosmetic it is.

Under these circumstances, there has been a desire to develop cosmetics that are both enjoyable and beautiful, which can distinguish between different types of emulsion formulations, and which can achieve both aesthetic beauty and desired functionality.

[Means to solve the problem]

As a result of intensive research to solve the above problems, the present inventor discovered that it is possible to disperse a W10 type emulsion in a translucent gel base or a transparent gel base in a three-dimensional pattern, and the results obtained in this way. The product is beautiful in appearance, has excellent three-dimensional pattern stability, and has W/O/
We have discovered that it is possible to obtain a cosmetic that can be recognized at a glance as a W-type emulsion, leading to the completion of the present invention.

That is, the present invention relates to a cosmetic material characterized by dispersing a W10 type emulsion in a three-dimensional pattern in a translucent gel base or a transparent gel base.

The present invention will be explained in detail below.

First, the substances that form 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 higher when neutralized with alkali or the like, and can be a natural or synthetic water-soluble polymer. Specifically, cellulose derivatives such as methylcellulose, hydroxyethylcellulose, hydroxypropylcellulose, and carboxymethylcellulose, natural polymers such as sodium alginate, carrageenan, quince seed gum, xanthan gum, and hyaluronic acid, polyvinyl alcohol, carboxyvinyl polymer, Examples include water-soluble polymers such as synthetic polymers such as sodium polyacrylate, polyacrylic acid, and glycerin polyacrylate ester.

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 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
ooo centipoise (hereinafter referred to as cp) or more, preferably so, oo.

62 or higher. The upper limit of the viscosity of this gel base is not necessarily limited as long as it can be filled. Note that the individual water-soluble polymers mentioned above have different viscosity characteristics when dissolved or dispersed in water, so concentration adjustment or
The viscosity can be adjusted appropriately by mixing more than one type of water-soluble polymer.

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

As the coloring agent used for the gel base, water-soluble colorants are preferable, such as water-soluble tar pigments such as Red No. 2, Yellow No. 4, Yellow No. 5, and water-soluble ones such as vitamin B□2, shikonin, copper chlorophyllin sodium, etc. Examples include natural dyes.

Next, the w10 type emulsion, which is also applied to the present invention, contains hydrocarbons, triglycerides,
It consists of higher esters, higher alcohols, higher fatty acids, silicone oils, oil-soluble additives such as antioxidants, ultraviolet absorbers, preservatives, and surfactants. It consists of alcohols, humectants, water-soluble vitamins as water-soluble additive ingredients, amino acids, sugars such as monosaccharides and polysaccharides, preservatives, etc.
Each - inside the shell is used in cosmetics. This W10 type emulsion is made by selecting these oil phase components and aqueous phase components according to the purpose of the cosmetic, and adding the water phase components, which were also heat-dissolved and mixed while stirring, to the oil phase components that have been heat-dissolved and mixed. regular.

It is then cooled and manufactured. This W10 type emulsion itself is useful as cosmetics such as cold cream and hand cream.

The proportion of the oil phase component in the entire w10 type emulsion is:
It is 5 to 70 wt%. This W10 type emulsion can also be colored with a coloring agent to further enhance its beauty. 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, Blue No. 1, etc. Examples include tar pigments, natural pigments such as lashicaic acid, carminic acid, and guaiazulene, and colored synthetic resins such as polyethylene and polyethylene phthalate.

These coloring agents can be applied as they are or after having been previously treated with anti-inflammatory treatment such as silicone oil. Although the amount of the colorant may vary depending on the intended dosage form and the type of colorant used, it is generally within the range of 30% by weight or less and 0.001% by weight or more based on the entire W10 emulsion. However, it is also possible to adjust as appropriate by mixing two or more of the above colorants.

To disperse these W10 type emulsions in a three-dimensional pattern in the gel base, for example, the following method is used.

The W10 type emulsion and the gel base are continuously filled into a container by a simultaneous filling method (inner phase: W10 type emulsion, outer phase Nigel base), and the W10 type emulsion exhibits a three-dimensional pattern in the gel base. A cosmetic of the present invention is obtained.

For example, W1 in the filling nozzle for dispensing the gel base.
The transparent gel base and the W10 type emulsion are simultaneously filled into a container that can rotate or move in a fixed direction using a multiple filling nozzle with a built-in sub-nozzle for supplying the type 0 emulsion. Inside w/o
It is possible to produce cosmetics in which mold emulsions are dispersed in a three-dimensional pattern. At this time, by combining the size and rotational speed of each nozzle or the rotational speed of the container, it is possible to draw various three-dimensional patterns. Here, the amount of W10 type emulsion blended in the cosmetic of the present invention can be arbitrarily determined depending on the purpose, use, etc. of the cosmetic, but is preferably 0.1 to 10% by weight for aesthetic appearance. A range of is suitable. If it is less than 0.1% by weight or more than 10% by weight, it becomes difficult to obtain an aesthetic three-dimensional pattern. The three-dimensional pattern referred to here is w/.

A shape formed by a continuous phase or an intermittent phase of a mold emulsion, for example, a geometric pattern such as a helical shape.

The cosmetic of the present invention obtained as described above has a stable three-dimensional pattern and an aesthetic appearance, and when used, the desired makeup effect is obtained due to the synergistic effect of the gel base and the W10 emulsion. , w/o/w type emulsion-like effects are exhibited, and for example, skin care effects can be imparted.

Cosmetics proposed by the present invention include, for example, make-up products such as under-make-up, basic cosmetics such as eyelashes, packs, nutritional creams, and eye creams.
