Figure 2 is a photograph comparing the lipid production effect by Nile Red Staining (Nile Red Staining) method.

The present invention comprises a composite powder coated with amorphous titanium dioxide on the surface of the plated aluminum oxide in the makeup cosmetics, thereby promoting the recovery of the damaged skin barrier to exhibit an anti-aging effect and at the same time correcting natural skin defects without loosening. Effects and adhesion and spreading properties and the like relates to a makeup cosmetic composition excellent in use and a method for producing the same.

Conventional anti-aging makeup cosmetics contain extracts of ingredients having an anti-aging effect on the skin or functional ingredients such as arbutin, vitamin C, retinol, oleanoic acid, and the like, to realize the effect. It has been developed to express youthful skin by making skin look clean through color change.

However, in such a case, it is difficult to contain a sufficient amount of the efficacy ingredient due to the nature of the makeup cosmetics having a high powder content, in particular, in the case of water-soluble components, it is impossible to contain an amount that can realize the efficacy in cake or powder makeup cosmetics other than liquid foundation foundations. Reliability on aging efficacy was bound to fall.

In addition, in the case of functional ingredients such as arbutin, vitamin C, retinol, oleanoic acid and the like, they are destroyed by reaction with powders having a charge effect on the surface, and thus the makeup cosmetics containing powder due to a tendency to rapidly decrease the activity of the ingredients. Has great difficulty in application. In addition, even if the makeup cosmetics or powdery makeup cosmetics sufficiently contain the above functional ingredients and stabilize the functional activity, the powder makeup is not absorbed into the skin but exists on the surface of the skin, thus raising the question of anti-aging efficacy. to be.

Accordingly, the present inventors have attempted to develop a new cosmetic composition that can be easily applied to the makeup cosmetic composition to solve the above problems and can exhibit an anti-aging effect only by applying to the skin surface, and the zeta potential of the surface (Zeta-Potetial) In the case of having a negative value, it is possible to promote the repair of damaged skin barrier (Arch Dermatol Res (1999), J Invest Dermatol 118 (2002), Br J Dermatol (2004)). I went ahead.

As a result, it was found that in the case of amorphous titanium dioxide, the surface has a negative zeta potential value, thereby facilitating the recovery of the damaged skin barrier. The present invention has been completed by discovering that the skin defect correction is natural and the feeling of use such as skin fit and spreadability is excellent.

Accordingly, it is an object of the present invention to provide a makeup cosmetic composition having an excellent feeling of use with natural skin correction having no anti-raising phenomenon while having an anti-aging effect of increasing the recovery rate of the skin damage site.

Still another object of the present invention is to provide a method for preparing the makeup cosmetic composition.

In order to achieve the above object, the present invention provides a makeup cosmetic composition containing a composite powder coated with amorphous titanium dioxide on the plate-shaped aluminum oxide surface.

In addition, the present invention is a method for producing a makeup cosmetic composition containing a composite powder, the first step of producing a composite powder coated with amorphous titanium oxide on the surface of the aluminum oxide plate; Pulverizing and mixing cosmetic ingredients such as oil-soluble oils, binders, pigments, sunscreens, preservatives, fragrances; And a third step of adding the composite powder prepared in the first step to the mixture ground and mixed in the second step.

Hereinafter, the present invention will be described in more detail.

In the present invention, it is characterized by containing a composite powder prepared by coating amorphous titanium dioxide on plate-shaped aluminum oxide in a makeup cosmetic.

Titanium dioxide (TiO ₂ ) is most widely used as a white pigment because of its high physical and chemical stability and high hiding power. In the case of makeup cosmetics, titanium dioxide, which is a white inorganic pigment, is most widely used. TiO ₂ ) has crystalline structures such as rutile, anatase, brookite, and amorphous forms.Burkite phase is not used in nature and is not used in practice. In general, rutile and anatase have high refractive index (n = 2.5 ~ 2.75) and have high hiding power, so they are most used in makeup cosmetics and paint industry. However, in the case of rutile or anatase, the whiteness is too high due to the high refractive index, and the makeup cosmetics containing the same have a disadvantage of appearing unnatural due to the fragility of the makeup in the expression of the skin. In particular, the content is increased to increase the coverage. If you do that, the phenomenon becomes more pronounced. Therefore, in the present invention, it is preferable to use amorphous titanium dioxide having a refractive index of n = 2.2 to 2.35, which has no lifting phenomenon compared to rutile or anatase, and which enables natural skin correction.

The amorphous titanium dioxide has a negative zeta-potential value to promote recovery of the damaged skin barrier. If the skin barrier damaged human body there is thereby to divalent calcium in the damaged area to increase the concentration of ions (Ca ^{2 +)} recovering the damaged area, calcium divalent ions (Ca ^{2 +)} As the concentration increased regeneration of damaged parts of the Will be faster. Therefore, when a substance having a negative value is applied to a damaged site in a manner that can increase the concentration of calcium divalent ions at the damaged site, it has a positive charge on the skin damaged site by attraction between opposite charges. By increasing the concentration of calcium divalent ions and effectively staying in the damaged area for a long time, it is possible to accelerate the rate of skin recovery. For this reason, in the present invention, it is preferable that the composite powder coated with amorphous titanium dioxide has a negative zeta potential value of (-) 7 or less. This (-) and had a value greater than 7 because of the calcium ion to not give the calcium changes in the ion concentration in the weak or damaged human (Attraction force) for the (Ca ^{2 +)} effect on skin damage regeneration Because it is not crazy.

In addition, in the present invention, by coating the amorphous titanium dioxide on the surface of a plate-shaped aluminum oxide having a smooth texture to produce a composite powder, it is possible to increase the feeling of use, such as adhesion and spreadability with a natural skin expression without lifting phenomenon.

Makeup cosmetic composition of the present invention is characterized in that the amorphous titanium dioxide is contained in an amount of 5 to 30% by weight, more preferably 5 to 15% by weight based on the total weight of aluminum oxide and coated on aluminum oxide. This is because if the content of amorphous titanium dioxide is less than 5% by weight lacks the anti-aging effect, if it exceeds 30% by weight is difficult to express the natural skin due to the increase in whiteness.

In the makeup cosmetic composition of the present invention, the plate-shaped aluminum oxide is characterized in that the average particle diameter of the particles is 5 ~ 15㎛, the maximum linear diameter / thickness is 5 ~ 40㎛, the specific surface area 1 ~ 4 m ² / g do.

In the case of a powder having a negative zeta potential, it is important to increase the specific surface area as the contact area with the surface of the skin increases, thereby increasing the specific surface area. Therefore, by coating the powder on a plate powder having a high diameter / thickness ratio, The contact rate with the skin can be increased compared to the amount used, thereby maximizing the effect. Accordingly, the plate-shaped aluminum oxide preferably has a maximum linear diameter / thickness of 5 to 40. This means that when the maximum linear diameter / thickness of the plated aluminum oxide is less than 5, the diameter becomes smaller and the thickness becomes thicker, so that the effect of increasing the contact rate between the powder and the skin is insufficient, and the color also does not exhibit a bright color tone and a bluish color. If it exceeds 40, it has a gloss because it can exhibit an unnatural luster when used in base makeup cosmetics.

The plate-shaped aluminum oxide has a small contact ratio with the skin when the average particle diameter is less than 5 μm, which is insufficient in anti-aging effect. In addition, when the specific surface area is less than 1, the anti-aging effect to be obtained due to the decrease in the contact rate with the skin is insufficient, and when the specific surface area is more than 4 m ² / g, the specific gravity is too low, so in the case of liquid cosmetics in the development of the makeup formulation, It may act as a cause of the increase, in the case of powder formulation may cause a decrease in feeling, such as powder blowing.

The makeup cosmetic composition of the present invention preferably contains 0.5 to 40% by weight of the composite powder based on the total weight of the cosmetic composition. If the content of the composite powder is less than 0.5% by weight, the effect can not be sufficiently exhibited. If the content of the composite powder exceeds 40% by weight, the effect of make-up makeup is reduced due to excessive bundling by plate aluminum oxide, and further changes in the anti-aging effect are observed. Because it does not have.

The coating method of the amorphous titanium dioxide on the surface of the plate-shaped aluminum oxide is water, aluminum oxide, and acid, and the mixture is heated and stirred, and then the aqueous titanium chloride or titanium sulfide solution is added at a constant rate to coat amorphous titanium dioxide. After neutralizing, washing with water, filtration, washing with water, drying, and coating by heat treatment, the coating method is not particularly limited.

Formulation of the makeup cosmetic composition is characterized in that selected from the group consisting of makeup primer, foundation, makeup base, two-way cake, pact, powder, eye shadow, lipstick, lip gloss, lip liner. The composition of each of the above formulations may contain various bases and additives necessary for the formulation of the formulation and appropriate, and the type and amount of these components can be easily selected by those skilled in the art.

In addition, the present invention is a method for producing a makeup cosmetic composition containing a composite powder, the first step of producing a composite powder coated with amorphous titanium oxide on the surface of the aluminum oxide plate; Pulverizing and mixing cosmetic ingredients such as oil-soluble oils, binders, pigments, sunscreens, preservatives, fragrances; And a third step of adding the complexed pigment prepared in the first step to the mixture ground in the second step.

Cosmetic components such as oil-soluble oils, binders, pigments, sunscreens, preservatives, fragrances can be suitably selected and blended by those skilled in the art using known ones.
