BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a flow chart of a method of making a makeup cosmetic composition comprising an emollient oil, a water-soluble moisturizer and a silicone gel according to an embodiment of the present invention.

Hereinafter, the present invention will be described in detail.

The present invention is characterized by comprising 50 to 72% by weight of a powder, 3 to 10% by weight of a water-soluble moisturizer, 5 to 10% by weight of a silicone gel, and 20 to 30% by weight of an emollient oil.

The components of the powder used in the present invention may include extender pigments, pigments and white pigments commonly used in makeup products, and specifically include talc, mica, sericite, silica, nylon powder, silicone powder, polymethyl It is preferable to use at least one selected from the group consisting of polymethyl methacrylate (PMMA), boron nitride powder and barium sulfate, but they are not limited thereto.

In the composition of the present invention, the powder may be either coated or uncoated, and is preferably used in an amount of 50 to 72% by weight based on the total weight of the composition.

When the content of the powder relative to the total weight of the composition is less than 50% by weight, the composition becomes an oil dispersion type form of an oil continuous phase having a large amount of oil binder and becomes an oil dispersion form difficult to form into a semi-solid type, There is a disadvantage in that the oil content is relatively small and the moisture property, which is similar to the general fact composition, is poor or dry, exhibits normal persistence, or does not pay off due to the caking phenomenon.

The caking phenomenon means that the powder is changed into a hard and hardened form by heat, pressure, and moisture.

The pay-off means that no cosmetic is applied to a makeup tool to be used.

The water-soluble humectant used in the present invention is preferably used in an amount of 3 to 10% by weight based on the total weight of the composition.

When the content of the water-soluble moisturizer is less than 3% by weight based on the total weight of the composition, it is difficult to feel a feeling of moisturizing. If the content is more than 10% by weight, sticky texture unique to the moisturizing ingredient becomes strong.

As the water-soluble moisturizing agent in the composition of the present invention, any water-soluble moisturizing component conventionally used may be used. Specific examples thereof include glycerin, butylene glycol, hyaluronic acid, propylene glycol, Algae extract, Camellia Sinensis Leaf Extract, It is preferable to use at least one selected from the group consisting of Mannitol, Hexanediol, Amorphophallus Konjac Root Extract, Panthenol, and Sorbitol, but the present invention is not limited thereto .

It is preferable that the silicone gel composition is used in an amount of 5 to 10 wt% based on the total weight of the silicone gel composition and 20 to 30 wt% of the emollient oil.

If the content of silicone gel and emollient oil is less than 5% by weight and less than 20% by weight based on the total weight of the composition, the makeup consistency and skin adhesion are inferior. If the content of silicone gel and emollient oil is 10% Powder aggregation phenomenon and unevenness are generated.

As the emollient used in the present invention, any emollient and silicone oil that are conventionally used may be used. Specific examples thereof include diisostearyl malate, Dicetearyl dimer dilinoleate, hexyl laurate, Squalane, pentaerythrityl tetraisostearate, It is preferable to use at least one selected from the group consisting of octyldodecyl stearoyl stearate, dimethicone, and phenyl trimethicone. However, It is not.

The silicone gel used in the present invention is KSG-15 from Shinestu. Dow Corning EL-8051IN Silicone Organic Elastomer Blend from Dow Corning, Dow Corning EL-8052IH, available from Dow Corning Incorporated, Silicone Organic Elastomer Blend, Dow Corning EL-8050ID Silicone Organic Elastomer Blend, etc. However, since the silicone gel raw materials specially manufactured according to the requirements of those skilled in the art can also be applied, no.

The present invention relates to a process for producing a primary mixed dispersion comprising the steps of (S1) introducing a powder, a water-soluble moisturizing agent and an emollient oil into a Henschel mixer to obtain a primary mixed dispersion after primary mixing and dispersion, (S2) of obtaining a secondary mixed dispersion after secondary mixing and dispersion of the secondary mixed dispersion; and (2) a step (S2) of obtaining a secondary mixed dispersion after the secondary mixed dispersion is obtained by pulverizing the secondary mixed dispersion using a roll mill equipped with a Henschel mixer (S3), and compressing the powder obtained in the step (S3) into a molding dish (S4).

The manufacturing method of the present invention will be described separately for each step.

The powder, the water-soluble moisturizing agent, and the emollient oil are introduced into a Henschel mixer to perform primary mixing and dispersion, followed by a step (S1) of obtaining a primary mixed dispersion.

The powder is put into a Henschel mixer and mixed. Then, a binder mixed with a water-soluble humectant and an emollient oil is sprayed and mixed for 3 to 6 minutes to prepare a primary mixed dispersion.

The composition of the primary mixed dispersion is important for the feeling of use of make-up cosmetics to be moist and soft, and to be excellent in persistence.

The primary mixed dispersion of the present invention contains 50 to 72% by weight of the powder, 3 to 10% by weight of the water-soluble moisturizer, and 10 to 15% by weight of the emollient oil, based on the total weight of the makeup composition.

A step (S2) of adding a mixture of silicone gel and emollient oil to the primary mixed dispersion to obtain a secondary mixed dispersion after secondary mixing and dispersion is performed.

In step S2 of obtaining the secondary mixed dispersion, 5 to 10% by weight of silicone gel and 10 to 15% by weight of emollient oil are mixed with the primary mixed dispersion for 5 to 30 minutes while spraying 2 to 20% by weight of the make- Car mixed dispersion.

The reason why it is mixed and dispersed in the first and second order is that when all the water-soluble humectant, silicone gel and emollient are put into the Henschel mixer like ordinary semi-solid type makeup cosmetics, the water-soluble humectant and silicone gel do not mix with each other, The emollient oil and the silicone gel are not uniformly dispersed in the powder, thereby causing a problem of staining.

Accordingly, a water-soluble moisturizing agent and an emollient oil are first and uniformly dispersed in a powder by using a Henschel mixer to prepare a primary mixed dispersion, and a secondary mixed dispersion is prepared by dispersing the silicone gel and the emollient oil in a second step.

The second mixed dispersion is pulverized by using a roll mill mounted on a Henschel mixer to obtain a powder (S3).

The use of the rolls allows more uniform crushing of the secondary mixed dispersion while more evenly mixing the water-soluble moisturizer, silicone gel, emollient oil and powder contained in the secondary mixed dispersion.

The roll mill is composed of two or more cylindrical rolls each having a horizontal axis and having the same diameter, and a raw material to be crushed is fed between rolls rotating in opposite directions to compress the raw material between the rolls and crushed It says.

Usually raw materials are fed by a gravity-drop method and the size of the pulverized product is controlled by varying the distance between the rolls. Since the particle size distribution of the pulverized product is narrow and the retention time is very short, the pulverized powder is difficult to get into the rollers and the pulverized contents are difficult to recover. It is difficult to be pulverized because it is adhered and is mainly used for wet grinding and dispersing of a dispersion having an appropriate viscosity.

The crushing efficiency is related to the number of rolls, the interval of rolls, the rotation speed of rolls, and usually 2, 3 or 4 roll mills are mainly used.

In the present invention, the composition may be completed by performing a roll mill process at a speed of 300 to 1,500 rpm for 2 to 3 times at a second-stage to a fourth-stage roll mill.

When the speed is less than 300 rpm, the secondary mixed dispersion is not mixed uniformly. Particularly, the emollient oil and silicone gel are not uniformly dispersed in the powder, resulting in unevenness. When the speed exceeds 1,500 rpm, Frictional heat is generated and thermal deformation of the secondary mixed dispersion is given to increase the defective rate of the final product.

The powder obtained in the step (S3) is placed in a molding dish and compression molding is performed (S4).

The powder was placed in a molding dish and compression molded at a pressure of 150 to 300 kgf / cm ² for 3 to 10 seconds to prepare a final product.

When the pressure is less than 150 kgf / cm ² , the powder is easily broken off from the dish, and when the pressure is more than 300 kgf / cm ² , the strength of the compressed powder is too strong so that the powder is not buried in the brush or puff. There is a problem that it is difficult to carry out.

The semi-solid make-up cosmetic composition according to the present invention may have a moist and soft feeling and a good durability. The semi-solid makeup cosmetic composition may be produced as a form of the present invention and is not limited to the conventional formulations, but may be twin cakes, compacts, And press powder. The composition of each of these formulations may contain various kinds of bases and additives necessary for formulation of the formulation, and the kinds and amounts of these ingredients can be easily selected by those skilled in the art.

Hereinafter, examples, comparative examples and test examples of the present invention will be described in detail.
