Makeup cosmetics are used for the purpose of making the skin beautiful by changing the appearance beautifully. It is divided into base makeup, which is used to equalize the skin color of the entire face and cover the flaw, and point makeup, which partially increases the three-dimensional effect such as lips, eyes, and nails. Base makeup consists of makeup base, foundation, powder, etc. Point makeup consists of lip cosmetics and eye makeup cosmetics.

In general, the conditions for makeup cosmetics should be applied to the skin, so that there should be no irritation to the eyes, and the drying speed should not be soaked immediately after application, and it will not be easily spread to sweat, tears, and oil, and to be free of powder dust. It is easy to apply, has no burden on use, is less likely to be contaminated with microorganisms, and should be easily removed when washing.

For example, the prior art related to the cosmetic composition contained in cosmetics is disclosed in Korean Patent Publication No. 10-2013-0033772, which relates to a makeup cosmetic composition, 0.1 to 50 parts by weight of a moisture-containing skin softening polymer, It relates to a makeup cosmetic composition comprising 1 to 70 parts by weight of the water-soluble component, and 1 to 50 parts by weight of the oil component.

The prior art has a water-soluble components occupy most of the makeup cosmetic composition, there is an effect having a moist and fresh feeling when applied to the skin.

However, the prior art has a problem in that the dispersibility of the water-soluble component and the pigment is lowered due to the hydrophilic property of the water-soluble component and the hydrophobic property of the pigment, thereby preventing the vivid color from being expressed.

In addition, the prior art has a disadvantage in that the evaporation rate of the water-soluble component is faster over time to feel dry easily on the skin, weak in color maintenance and persistence.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings, and the method for preparing a self-elastic restoration makeup cosmetic composition including the hydrophobic silica of the present invention preferably includes the following steps, but is not limited thereto. .

The present invention is a step of preparing an oil base by mixing and stirring the oil, the pigment and mica while maintaining at 70 to 95 ℃ (S10), and the content of the first hydrophobic silica in the oil base while maintaining 40 to 70 ℃ After the addition of 10 to 30% by weight to prepare a first mixture by stirring (S20), and while maintaining the 40 to 70 ℃ 10 to 30% by weight of the content of the initial hydrophobic silica to the first mixture after Preparing a second mixture by stirring (S30) and adding 40 to 80 wt% of the initial hydrophobic silica content to the second mixture while maintaining 40 to 70 ° C. to prepare a third mixture by stirring. (S40) and while maintaining a 40 to 70 ℃ characterized in that it comprises a step (S50) to prepare a final mixture by adding a moisturizing agent and a film forming agent to the third mixture.

The manufacturing method of the present invention will be described by dividing each step as follows.

Maintaining at 70 to 95 ℃ and after mixing the oil, the pigment and the mica is stirred to perform the step of preparing an oil base (S10).

The step (S10) to prepare an oil base by mixing the oil, pigments and mica for the appearance of vivid color. Mixing the pigment and mica with oil first is to prevent layer separation while improving the dispersibility of the pigment and mica.

Oil, pigments and mica are dispersed by stirring for 10 to 20 minutes at 3,000 to 5,000 rpm, there is a problem that the formulation is unstable because the dispersion power is lowered at less than 3,000 rpm and less than 10 minutes, bubbles if more than 5,000 rpm and 20 minutes There is a problem that lowers the viscosity and increases the defective rate of the makeup cosmetics.

The step (S20) to (S40) is to divide and disperse the hydrophobic silica three times in a fluidized bed dispersion process by mixing the oil base and hydrophobic silica prepared in the step (S10).

Adding 10 to 30% by weight of the initial hydrophobic silica content to the oil base while maintaining 40 to 70 ° C., followed by stirring to prepare a first mixture (S20), and maintaining the first to 40 to 70 ° C. Adding 10 to 30% by weight of the initial hydrophobic silica content to the mixture, followed by stirring to prepare a second mixture (S30), and 40 to 70% of the initial hydrophobic silica content in the second mixture while maintaining the 40 to 70 ℃ After the addition of 80% by weight, stirring is performed to prepare a third mixture (S40).

The step (S20) to (40) is to divide the hydrophobic silica into three times and mixed with the oil base prepared in step (S10), so that the hydrophobic silica is sufficiently collected in the oil base.

The step (S20) to (S40) is stirred the oil base and hydrophobic silica for 10 to 30 minutes at 200 to 500 rpm. If the stirring speed is less than 200 rpm and the stirring time is less than 10 minutes, the hydrophobic silica is not sufficiently collected in the oil base, and thus the makeup cosmetic composition cannot have self-elasticity recovery properties, the stirring speed is more than 500 rpm, and the stirring time is If it is more than 30 minutes, some hydrophobic silica will form a floating layer without being trapped in an oil base, and there exists a problem that formulation becomes unstable.

Proceeding to the step (S40) is produced a makeup cosmetic composition having a self-resilience recovery, even if a large force is applied to the cosmetic composition is restored back to its own shape in a short time, when a small force has a firm texture Make-up cosmetic composition that can be interesting to use the product can be made, and when applied to the skin can improve the skin's swelling and elasticity to improve the skin wrinkles and at the same time can achieve a smooth and excellent effect.

Maintaining 40 to 70 ℃ to add a moisturizer and film forming agent to the third mixture, followed by stirring to prepare a final mixture (S50).

The moisturizer and the film-forming agent are added to the third mixture prepared in step S40 and stirred at 300 to 800 rpm for 5 to 10 minutes.

If the stirring speed is less than 300 rpm, and the stirring time is less than 5 minutes, the moisturizer and the film-forming agent are not evenly stirred with the third mixture prepared in step (S30), there is a problem that the formulation is agglomerated, more than 800 rpm, 10 minutes If it exceeds, there exists a problem that the effect of a moisturizing agent and a film forming agent becomes low. In particular, the film-forming agent does not form a thin film film on the skin has a problem that the cosmetic is buried.

As shown in Table 4, the restoration time is fast in Examples 4 and 5, and it was confirmed that the texture had a firm texture in the elasticity evaluation, and the skin wrinkle improvement effect was also excellent.

It was found that when the content of hydrophobic silica is 15 to 25% by weight, it is sufficiently collected in oil to have self-elasticity restoring power. The cosmetic composition is applied to the skin surface by removing the makeup cosmetic composition of Examples 4 to 5 and spreading it on the skin. It was found that the elasticity is restored to the initial state after the deformation in the first place, and the effect of improving skin wrinkles is superior to Examples 2, 3, 6, and 7.

However, the composition of Example 2 has a low hydrophobic silica content and is prepared in a dilute gel-like formulation, and when the composition is floated with a spatula, the composition can be restored to the initial state and the restoration time cannot be measured. It is not implemented in a formulation with elastic restoring force.

The composition of Example 3 was the fastest restoration time, but was implemented as a formulation with elasticity, but the texture was very soft and did not significantly improve the skin wrinkles when applied to the skin.

The composition of Example 6 was able to obtain a similar effect as the composition of Examples 4 to 5 restoration time, skin wrinkle improvement effect, elasticity.

* The composition of Example 7 had a longer recovery time with a content of hydrophobic silica of more than 40% by weight, and felt a hard texture rather than a firm texture, but a slight skin wrinkle improvement effect was obtained.

Therefore, the present invention was able to prepare a makeup cosmetic composition having a self-elasticity when the content of the hydrophobic silica 5 to 40% by weight through Test Example 2, 15 to 25% by weight of the optimal hydrophobic silica in the present invention It confirmed that it was the range of content.

What is described in the present invention is only an embodiment for a self-elastic restoration makeup cosmetic composition and a method for producing the same comprising a hydrophobic silica, the present invention is not limited to the above embodiment can be implemented in a variety of different forms, This embodiment is provided only to make the disclosure of the present invention complete, and to fully convey the scope of the invention to those skilled in the art, and the present invention is defined by the scope of the claims. It will be.
