Description

Skin care makeup composition containing complex multifunctional powder and oil

The present invention provides a skin care makeup composition containing a composite multifunctional powder and an oil, and more particularly, by combining the composite multifunctional powder and an oil in an appropriate ratio, and having an optical diffusion effect, skin defects such as fine lines, blemishes, pores, etc. The present invention relates to a skin care makeup composition capable of concealing a natural makeup finish.

In general, color cosmetics should have a natural make-up effect and at the same time cover. However, there is a technical difficulty in satisfying both conditions at the same time because natural finishing and covering power are opposite requirements.

Titanium oxide, for example, has excellent coverage but has a thick make-up, resulting in unnatural finishes, and when used in large quantities, the product experiences roughness and poor development and does not pay-off the contents, resulting in caking. After makeup, the base tends to bounce white and looks excited. On the contrary, flake powders such as mica and sericite do not have a thick feeling, but they lack cover power, and when the makeup is pushed, the contents become smudged and pay off, but the contents are severely damaged. In addition, spherical powders such as silica powder and nylon powder can be used for light makeup but have poor skin adhesion.

Therefore, the present inventors have studied the makeup composition which can satisfy the natural finishing and covering power at the same time by improving the above disadvantages. As a result, the skin care makeup composition in which the composite multifunctional powder is properly mixed with oil can satisfy the natural finishing and covering power at the same time. It has been found that the present invention can be completed based on this finding.

It is an object of the present invention to provide a skin care makeup composition containing a composite multifunctional powder and an oil.

The skin care makeup composition of the present invention has good soft feel and developability, and is excellent in skin adhesion and hiding power. And in the case of powder products, the payoff of the contents is good and does not break easily.

The composite multifunctional powder used in the composition of the present invention diffuses the barium sulfate and the light having good light refractive index and application property to the mica which cleaves the mica which has good spreadability and spreadability and low light refractive index and diffuse reflection, and blocks ultraviolet rays. The fine particle titanium oxide is coated uniformly. At this time, the composition of the composite multifunctional powder is 10-20% of fine particle titanium oxide, 20-30% of barium sulfate and 50-70% of fine mica.

The fine mica preferably has a thickness of 0.1 mu m or less and a particle size of 1 mu m to 15 mu m.

Such a multifunctional powder is a powder that has a covering power even with thin makeup due to a natural finishing and visual scattering effect, and also has a UV blocking effect.

Here, the visual scattering effect refers to an effect of making skin defects (roughness of roughness, fine wrinkles, pores, etc.) invisible by applying diffuse reflection, refraction, and transparency of light. For example, even if a single piece of vinyl cannot cover the outline of an object, it is the same as overlapping several sheets of the same vinyl to blur the outline of the object due to the diffuse reflection and refraction of light, making it difficult to tighten.

Since the composite multifunctional powder used in the present invention has a thickness of about 1/5 to 1/6, compared to sericite, mica, and talc, which are conventionally used, even when the powder is stacked in double or triple layers, it is thinner and more natural than conventional powders. On the other hand, it has a visual scattering effect that makes the defects of the skin invisible by diffuse reflection and refraction of light.

However, even if the composite multifunctional powder has a visual scattering effect, it is difficult to expect the effect when properly mixed and used in color cosmetics. This is because the visual scattering effect can be maximized only when the composite multifunctional powder and oils are used at an appropriate mixing ratio. In other words, the mixture of the multifunctional powder and oils (visual scattering mixture) in the range at a certain ratio shows a good visual scattering effect, but when it is out of the ratio range, the effect is insignificant even when a large amount of the multifunctional powder or oil is used. Appears.

The inventors measured the reflectance and transmittance of the visual scattering mixture coating film, and synthesized the results obtained through the panel test to determine the visibility of skin defects. Figured out.

In the case of compression molded powder products, the visual scattering effect is maximized when the total composition contains 5-20% of the composite multifunctional powder and 5-15% of the oils.

In the case of emulsified cream foundation, the visual scattering effect is maximized when the composite multifunctional powder is 3 to 10% and the oils are 10 to 20%.

As the skin care makeup composition containing the composite multifunctional powder and the oil of the present invention, compression molding powder foundation, cream foundation and compression molding powder eye shadow can be prepared.

These specific manufacturing methods are explained in full detail.

1. Compression Molding Powder Foundation.

15% to 30% of sericite, 5 to 15% of nylon powder, 20 to 40% of talc, 5 to 20% of pigments and preservatives and 5 to 20% of complex multifunctional powder, and then 5 to 15% of oil heated to 50 to 60 ° C. In addition, it manufactures by making the whole into 100, grind | pulverizing, and shape | molding.

2. Cream Foundation.

10-10% of oils such as liquid paraffin, squalane, octylate acid octyl dodecyl, and methylpolysiloxane are added with 5 to 10% wax such as stearic acid, cetanol and glycerin monostearate to adjust the hardness, and monostearic acid sorbitan and monooleic acid 0.5-2.5% of emulsifiers, such as a pleoxy ethylene sorbitan, are added, and it heats at 75-80 degreeC.

Next, 2 to 15% of 1,3-butylene glycol, 0.5 to 1.0% of triethanolamine, 0.5 to 1.5% of magnesium aluminum silicate, and an appropriate amount of preservative, pigment and 3 to 10% of the composite multifunctional powder were mixed in 40 to 70% of purified water. After heating, the oil and wax parts are slowly emulsified while heating to prepare to cool to room temperature.

3. Compression Molding Powder Eyeshadow

15-25% mica titanium, 4-10% zinc stearate, 0-10% pigments, 20-40% talc, 5-15% composite multifunctional powder, 5-15% oil heated to 50-60 ℃ Add 100 to make the whole and grind and shape it.

The color cosmetic composition according to the present invention has the following advantages over conventional color cosmetics.

Conventional color cosmetics use powders with high refractive index such as titanium oxide or mica coated with titanium oxide to make the difference in light brightness on the upper part of the face surface during makeup so that the skin defects such as wrinkles, pores, blemishes, etc. It will stand out on the skin and make up a lot of make-up to compensate for this, making the finish unnatural.

However, the color cosmetic composition of the present invention has a low light refractive index and diffused reflection of light due to the low blending of the multifunctional powder and the oil, resulting in less difference in the brightness of the light on the surface of the face during make-up, resulting in blurry contours of the skin defects. It is difficult to see well and the skin looks clean even with light makeup.

Therefore, the color cosmetic composition of the present invention exhibits a remarkable effect that can satisfy the natural finish and coverage at the same time by completely solving the problems not solved in the conventional products.
