Description

Manufacturing method of cosmetic composition using volatile mixed solvent and its cosmetic composition {Fabricating method of cosmetic composition using volatile solvent}

Related to makeup powder-based cosmetic manufacturing technology.

The makeup cosmetics began when the ancient human race began to apply natural pigments to the body for the purpose of protecting the face and body or for religious purposes. Rice flour was used as a face powder from ancient times, but it was first made and used in the 7th century. After that, light powder and light white powder were used, and the damage of lead poisoning became obvious, and after the ban on manufacturing and selling, Came out.

Make-up cosmetics can be divided into base make-up groups such as two-way cakes, foundation and face powder, and point make-up groups such as lipstick and nail cosmetics depending on the makeup area. Depending on the formulation, emulsion type such as emulsified foundation, make- Skin cover, lipstick, etc., and powder type such as two-way cake and face powder.

Makeup cosmetics have the function of covering or concealing the flaws of the skin and imparting beautiful color, that is, beautifying the skin, and protecting the skin such as nourishing, converging effect, moisturizing function and protecting the skin from UV rays. There is a function. Furthermore, it is also used for the purpose of giving psychological stability by skin beautification and skin protection functions.

Makeup cosmetics generally vary slightly depending on the formulation, but are generally oil-based ingredients such as squalane, powder ingredients used to cover color and skin imperfections, waxes and oil ingredients used to increase hardness and formulation stabilization, and It is composed of water-soluble ingredients that moisturize the skin.

Among these, powders are white pigments such as titanium dioxide and zinc oxide (zinc oxide) which have excellent hiding power of skin defects, sieving pigments such as talc, mica, sericite, nylon, and silica, and iron oxides and oxides that give color. It can be classified into coloring pigments such as chromium and organic pigments.

Looking at the general properties of the powder in more detail, in the case of powder components such as titanium dioxide and zincation, it is mainly used to control the coating power of the product, the hiding power of the powder is largely involved in the refractive index and the particle diameter. Because of this, but the high refractive index of titanium dioxide and zincation is mainly used as a white pigment, due to the characteristics of the metal oxides re-aggregation phenomenon occurs in the formulation to cause the phenomenon of aggregation after makeup. Particularly, in the case of titanium dioxide, the structure is tetrahedral, which causes damage to the skin when applied to the skin, and deteriorates malleability and usability. On the other hand, spherical powders such as silica, nylon powder and polymethyl methacrylate have excellent malleability, spreadability and sebum absorption ability, but have poor moisturizing feeling and adhesion, which lowers the persistence of makeup, deteriorates powder formability and It acts as a cause of dryness. Therefore, the preparation of makeup cosmetics is a situation that is necessarily used by mixing the powder with excellent malleability and excellent adhesion.

Currently, more than 90% of the powder pacts on the market are dry pacts, which provide various functions to cosmetics to improve agglomeration and dryness. In general dry pact, sieving pigments, white pigments, coloring pigments, etc. are put into a mixer, mixed, and then sprayed, mixed, and pulverized. It has been applied to most products used until recently, but it reveals a limit of feeling.

To overcome this drawback, a wet forming method called white injection was developed in the 1990s. In this method, IPA (Isopropyl alcohol) is used as a solvent to disperse the powder phase to produce a slurry type, and then the contents of the slurry type are filled into a plastic dish, and a certain amount of IPA is sucked through an inhaler and dried to obtain a finished product. IPA has the advantage of easily evaporating without leaving magnetic stains. By reducing the porosity in the powder, IPA can increase adhesion and malleability while minimizing powder blowing. In addition, it is possible to expect the inherent properties of the binder by increasing the dispersibility of the silicone and ester system used as the binder. However, due to the alcohol used as a solvent, the stability of the formulation is reduced, and there is a problem that cracks are formed during the drying process.

Going one step further from the existing dry and wet cosmetic manufacturing methods, it achieves both dry formulation stability and silky feeling and excellent spreadability of wet formulations, and has excellent powder moisturizing and soft feeling, together with improved powder aggregation and collapse prevention Cosmetic compositions and methods for producing the same are provided.

According to an aspect of the present invention, there is provided a method of manufacturing a powder mixture including makeup powder, dispersing the powder mixture in a volatile mixed solvent to form a slurry phase, and removing the volatile mixed solvent from the slurry phase. It may include.

In addition, according to a further aspect of the present invention, the above manufacturing method may further comprise the step of compressing and shaping the result obtained by removing the volatile mixed solvent from the slurry phase.

On the other hand, the composition according to one aspect of the present invention can be produced by the above-described manufacturing method based on the volatile mixed solvent. In other words, the composition according to an aspect of the present invention may have a dispersion state of 40 to 60% by weight of the powder mixture including the makeup powder and 60 to 40% by weight of the volatile mixed solvent as an intermediate material.

According to one aspect, the volatile mixed solvent is a first solvent comprising at least one of water, ethanol, and isopropyl alcohol, and Fiji-26-butes-26 (PPG-26- BUTETH-26) and a PG-40-hydrogenated castor oil (PEG-40-HYDROGENATED CASTOR OIL) may include a second solvent.

In addition, the volatile mixed solvent may include 99.9 to 95.0 wt% of the first solvent and 0.1 to 5.0 wt% of the second solvent.

The term makeup cosmetics as used herein broadly encompasses makeup cosmetics including cream molding powders, emulsion facts, skin covers, and the like, such as twin cakes, compacts, powder facts, wet molding facts such as pressed powders, and foundations . A person skilled in the art can easily determine the kind and content of the additive necessary for the formulation of the formulation according to the formulation of the cosmetic composition to be produced.

According to the disclosed contents, since the cosmetic composition is made by a liquid fluidized bed adsorption method based on a volatile mixed solvent, an excellent makeup cosmetic or makeup cosmetic composition which guarantees dry formulation stability, wet silky feeling and excellent spreadability at the same time is provided. Can be.

Hereinafter, specific examples for carrying out the present invention will be described in detail with reference to the accompanying drawings.

1 shows a schematic flow of a method of preparing a cosmetic composition according to one embodiment.

Referring to Figure 1, first to form a powder mixture (101).

The powder mixture according to the present embodiment includes a make-up powder. Makeup powder may include extender pigments, pigmented pigments, pearl pigments, white pigments, and the like, talc, mica, kaolin, sericite, silica, nylon powder, polymethyl methacrylate (PMMA), urethane, boron nitride, Titanium dioxide, zinc oxide, iron oxide, chromium oxide and the like can be used.

According to a further aspect, the powder mixture may further comprise a binder. As the binder, silicone oils, hydrocarbon oils, higher fatty acid oils, ester oils, glyceride oils, lanolin oils, vegetable oils, and the like may be used.

According to another additional aspect, the powder mixture may further comprise an additive. As the additive, pigments, flavors, thickeners, preservatives, surfactants, moisturizers, chelating agents and the like can be used.

However, the above-described makeup powder, binder, and additives are merely examples for clarity of understanding, and it is obvious to those skilled in the art that the scope of the present invention is not limited thereto. In addition, the makeup powder, binder, the composition ratio between the additives can also be variously changed according to the application purpose.

When the powder mixture is prepared, the powder mixture is dispersed in a volatile mixed solvent to form a slurry phase (102).

The volatile mixed solvent according to the present embodiment may be a mixed solvent of a predetermined first solvent and a second solvent. The first solvent may include at least one of water, ethanol, and isopropyl alcohol. The second solvent may include at least one of Fiji-26-Buteth-26 (PPG-26-BUTETH-26) and Fiji-40 Hydrogenated Castor Oil (PEG-40-HYDROGENATED CASTOR OIL). . The mixing ratio of the first solvent and the second solvent may be about 99.9 to 95.0 wt% of the first solvent and about 0.1 to 5.0 wt% of the second solvent.

According to a further aspect, when the powder mixture is dispersed in the volatile mixed solvent, about 40 to 60% by weight of the powder mixture may be dispersed in about 60 to 40% by weight of the volatile mixed solvent. If the content of the volatile mixed solvent is less than 40% by weight, the dispersibility of the coated makeup powder is lowered. If the content of the volatile mixed solvent is greater than 60% by weight, the uniformity and color deviation of the interlayer product may occur during the powder drying process, resulting in deterioration of product quality. Because there is.

The volatile mixed solvent is then removed from the resulting slurry phase (103).

For example, it is possible to thin the slurry phase to about 1.0 cm or less in a dryer, and then dry at about 60 degrees for 24 hours to remove the volatile mixed solvent. For the sake of understanding, the result of removing the volatile mixed solvent is called a powder phase.

Once the volatile mixed solvent is removed from the slurry phase to produce a powder phase, the resulting powder phase is compressed and shaped (104).

For example, it is possible to filter the powder phase and fill it in a predetermined amount on the molding dish, and then press-press the molding cloth to compress it.

As described above, according to the disclosed manufacturing method, since the cosmetic composition is manufactured by a liquid fluidized bed adsorption method based on a volatile mixed solvent, excellent makeup that ensures dry formulation stability, wet silky feeling and excellent spreadability at the same time Cosmetic or makeup cosmetic compositions can be prepared.
