Description

[0001] The present invention relates to a method of manufacturing a color cosmetic composition using an emulsion type color base,

More particularly, the present invention relates to a method for dispersing an emulsion type color base in a color cosmetic composition using a phase inversion emulsion, and more particularly, to a method for improving color dispersibility between pigments Color reproducibility is improved, color base is mass produced, and it can be commonly used for various products, so coloring is convenient and productivity can be improved by a simple manufacturing method.

Emulsion (emulsion) is a dispersion system that is mixed with a surfactant and energy added to a system that does not mix with each other spontaneously, such as water and oil. Sometimes it is separated into thermodynamically releasing energy to the outside world and returning to a stable layer separation state Unstable state. Emulsions can be classified into water-in-oil type and water-in-oil type. When silicone oil is used as oil, it is classified as silicone oil water, but silicon oil water is basically a kind of water-in-oil type.

The emulsion can be prepared by adding a disperse phase to a continuous phase containing a surfactant and using a direct emulsification method using a simple crushing power by an emulsifier, dissolving the surfactant in a dispersed phase, A phase inversion emulsification method for forming an emulsion, a liquid crystal emulsification method in which a liquid crystal is formed using a surfactant having a high phase transition temperature and a fatty acid alcohol, a nonionic ionic liquid A phase inversion temperature emulsification method in which fine emulsion particles are formed and cooled at the phase transition temperature of the surfactant, a method in which a gel in which an aqueous phase is dispersed in a lipophilic surfactant is dispersed in an oil phase or an organic degeneration containing a surfactant and an oil Gel emulsification method in which an oil gel containing clay minerals is dispersed in an aqueous phase ( gel emulsification method, and a membrane emulsification method in which uniform particles are formed using a Shiraz porous glass (SPG) membrane. The phase inversion emulsification method is a technique mainly used when it is not easy to directly inject a dispersed phase into a continuous phase.

Emulsion-type color cosmetics cover and compensate for defects such as spots and freckles, and express them with natural skin color. Therefore, the use of a pigment is essential for an emulsion type hue product to function. Pigments may also be used to color the skin, to hide spots and freckles, to use as an excipient, to improve the feeling of use, to protect the skin from the external environment such as ultraviolet rays, and to absorb sweat and sebum.

Emulsion type color cosmetics include foundation, makeup base, bib cream, skin cover, concealer, primer, makeup chest, sun cream and various products.

Emulsion-type color cosmetics mainly include inorganic pigments, and can be classified into extender pigments, color pigments, white pigments, pearlescent pigments, and special functional pigments. Among them, iron oxide is generally used as a color pigment, and a color pigment in which iron oxide is coated with silicon or silane is mainly used.

When a pigment is put in an emulsion type color cosmetic, it is put in a color base type in which color is base to enhance convenience and reproducibility. Generally, a compression grinding method and a mixed grinding method are mainly used as a method of base coloring pigment.

Compression milling is a method of dispersing colored pigments in a viscous oil phase followed by compression-milling with a three-step roller and then dissolving in oil phase in the production of foundation. It is very excellent in pigment dispersibility and reproducibility. But there is a disadvantage in that a large amount of raw material is lost and labor and time are required in the manufacturing process.

The mixed pulverization method is a method in which the coloring pigment and the excipient are uniformly mixed and then pulverized by a pulverizer and then dispersed in an oil phase or an aqueous phase by stirring to thereby reduce the loss of the raw material and reduce labor and time. However, It is difficult to use it because it does not have excellent color dispersibility and it can not be used commonly for various products.

Emulsion-type color cosmetics are different in color from each product, so it is inconvenient to color them in desired colors at the time of manufacture, and reproducible colors can not be produced at the time of manufacture, and problems such as poor compatibility between the pigments coated with different materials . The reason why the color is difficult to produce with reproducibility is due to the degree of crushing of the colored pigment. In order to make the pigment particles reproducible in each manufacturing process, the pigment must be extremely crushed, but in reality it is a problem caused by a large deviation.

Accordingly, it is an object of the present invention to overcome the above-described problems of the prior art, and to provide a method of manufacturing a coloring material which is low in loss of raw material, improves color dispersibility, high in color reproducibility, It is an object of the present invention to provide an emulsion-type color cosmetic preparation method capable of improving productivity.

Accordingly, the present inventors have found that the above object can be achieved by using a method of preparing a color base as an oil-in-water emulsion type color base, introducing the color base into a water-in-oil type emulsion and transferring the oil-in-water emulsion type color base into a water- Thereby completing the present invention.

The present invention relates to a method of preparing a color base in the form of an oil-in-water (O / W) emulsion type color base, charging it into a w / o type emulsion and then transferring the color base into a w / To a method for producing an emulsion-type color cosmetic composition by dispersing a pigment.

In describing the present invention, the term "color base" refers to a mixture in which one or more kinds of extender pigments, color pigments, white pigments, pearlescent pigments, and special functional pigments are mixed together and homogenized to facilitate the production of cosmetics.

In the present invention, an oil-in-water emulsion type color base capable of phase-inversion into a new color base has been developed. In the present invention, the oil-in-water emulsion type color base may be a mixed color emulsion type color base and a separate color emulsion type color base. The mixed color emulsion type color base is prepared by mixing and pulverizing a large number of colored pigments and other pigments, and then making the emulsion type color base by using water, oil and emulsifier, and making the emulsion type color base usable for preparing an emulsion type color cosmetic It says. In addition, the individual color emulsion type color base may be prepared by mixing and pulverizing a single coloring pigment and other pigment, then making the emulsion type color base into each color in the same manner, and selecting the desired individual color emulsion type color Base, respectively, so that they can be used for coloring.

A method for producing an oil-in-water emulsion type color base comprises first preparing a mixed color or individual color mixed powder type powder color, and then using the same to prepare an oil-in-water emulsion type color base. Pigments used in mixed color emulsion type color bases and individual color emulsion type color bases may be coated with silicon or silane, or an uncoated form may be used.

The prepared mixed color water-in-oil emulsion type color base was taken as desired or the individual color water-in-oil emulsion type color base was taken as desired and added to the water-in-oil type emulsion. When the oil base emulsion type color base was stirred, Is formed. As the phase takes place, the color particles are finely dispersed without aggregation, and the dispersibility is improved.

More specifically,

(1) a production step of putting a pigment into a mixer and mixing and pulverizing to form a powder type color base;

(2) a production step of dispersing the powder-type color base obtained in the step (1) in an oil phase containing a hydrophilic surfactant to form an oil phase;

(3) a step of preparing an oil-in-water emulsion type color base by injecting the resultant obtained in the step (2) into an aqueous phase and emulsifying the same;

(4) a step of preparing a water-in-oil type emulsion by charging an aqueous phase containing an oleophilic surfactant and emulsifying the water phase;

(5) a step of preparing a water-in-oil emulsion type color base obtained in the step (4) and injecting the oil-in-water emulsion type color base obtained in the step (3) into a water-in-oil emulsion type color base to prepare a water- The present invention relates to a process for producing a color cosmetic composition using a phase inversion emulsion of an emulsion type color base.

Also, the powder type color base to be fed into the oil-in-water emulsion type color base is mixed with 1 to 80% by weight. When the blending amount is too small, no color tone appears, and when the blending amount is too large, it may not be sufficiently dispersed.

In addition, the oil-in-water emulsion type color base, which is put into the water-in-oil emulsion-type color cosmetics and is transferred, is blended in an amount of 1 to 80% by weight. If the blending amount is too small, it is difficult to expect the effect of improving the color tone. If the blending amount is too large, the dispersibility becomes poor and it may become difficult to express a clear color tone on the skin.

The present invention also relates to a water-in-oil emulsion-type color cosmetic prepared by the above process.

The color cosmetic composition using the phase emulsification of the emulsion type color base according to the present invention improves color dispersibility between pigments having low loss of raw materials and poor compatibility and has high color reproducibility and mass production of color base and can be commonly used So that the coloring is convenient and the production is simple and the productivity can be improved.

Experimental Example  1: Measurement of raw material loss rate

The loss rate of the raw material of the final color base was measured in Comparative Example 1, which was treated three times with a three-roll roller by a compression milling method, and Example 16, which is an embodiment of the present invention. As a result, it was found that Comparative Example 1, which was treated with three rollers three times, caused 15% loss of raw material, whereas Example 16 of the present invention produced raw material loss ratio of 1% or less.

Experimental Example  2: Color dispersion test

Comparative Example 2 in which a color base was prepared by a mixed pulverization method which is one of common color bases and was used to prepare a general emulsion type color cosmetic composition and Examples 25 to 29 which are color cosmetic compositions using a phase emulsification of an oil- The emulsion particle photographs for 28 are shown in Fig. As can be seen in Fig. 1, a common color cosmetic composition has many black points, which means that the color dispersion is poor. On the other hand, in the embodiment of the present invention using the color phase-based phase inversion emulsification, the black point is remarkably reduced and the color dispersibility is good.

It can be seen that the color reproducibility is very excellent even if it is repeatedly regenerated because the color is dispersed in the color cosmetics using the phase inversion emulsification through the above embodiments.

In addition, in the case of conventional color cosmetics, since the color base prescription differs for each product, it is inconvenient to manufacture a color base separately for each product. However, the present invention is applied to mass production of individual color emulsion type color bases in advance, It is possible to use an appropriate amount for each time of manufacturing, so coloring becomes very convenient.

The color base is prepared in the form of an underwater type emulsion according to the method for producing a color cosmetic composition using the phase emulsification of the emulsion type color base of the present invention, and the emulsion type color base is transferred into a water-in-oil type emulsion, The emulsion-type color cosmetic composition is improved in color dispersibility between pigments having low loss of raw materials, poor compatibility, high color reproducibility, mass production of color bases and common use, The productivity can be improved.
