Description

Eye shadow composition with excellent durability

The present invention relates to an eye shadow composition having excellent durability. More specifically, the present invention is a highly dispersed pigment obtained by mixing the pigment pigment used in the eye shadow with a plate pigment such as talc, mica and the like as a re-agglomeration inhibitor and a dispersing aid, and atomizing using a jet-mill The present invention relates to an eye shadow composition containing coloring pigments and excellent in durability.

Eye shadow is a cosmetic that emphasizes the beauty of the eyes by applying shadow around the eyes, especially the upper eyelid, and giving a three-dimensional effect, and is one of the most diverse color ranges in the makeup cosmetics. The color used for the eye shadow is to give gloss by using mica titanium in general colors such as gray, brown, blue, or green or violet. It is a cosmetic that handles vivid colors such as lemon yellow. Constituents contained in these eyeshadows include powders such as talc, mica, kaolin, calcium carbonate, white pigments such as titanium oxide, zinc oxide, iron oxides, ultramarine blue, blue, manganese violet, chromium oxide, chromium hydroxide, Colored pigments such as tar-based pigments and pearlescent pigments such as surface treated pigments and mica titanium, which have been variously treated on the surfaces of these pigments, are mainly used (Cosmetic Science, Fragrance Journal). four). In addition, as a binder, metal soaps such as Mg-Myristate, Zn-Stearate, oils and waxes such as hydrocarbons, silicones, and higher fatty acids are used as binders. The skin around the eye where Eyesaido made with such a composition is used is easy to dry because there is little secretion of sweat and sebum, and the tissues of collagen and elastin, which are skin crystal tissues, are less coarse than other skins, so it has less elasticity and blood vessels. The nerves are concentrated and sensitive, the skin is prone to irritation, and there are no bones. In particular, since the upper eyelid has a lot of movement, the eyeshadow cosmetic is very important for the adhesion of the first application and the persistence of makeup lasting without dropping the eyeshadow cosmetic even after the movement of the eyelid after application. In addition, since persistence is the adhesion between the cosmetic and the skin is sustained, the adhesion and persistence are closely related.

The source of adhesion can be divided into Van der Waals Force, capillary force and electrostatic force between particles.The capillary force due to van der Waals force and moisture is proportional to the particle size and the electrostatic force is the square root of the particle size. It is proportional and it is different depending on the case when it is detached from the skin attachment part, but it is proportional to 2 to 3 square of the particle size (Aerosol Technology, John Wiley & Sons: powder engineering basic piece, Jinseo branch). It has a big impact on makeup persistence. Therefore, by atomizing the size of the particles it is possible to increase the adhesion and suppress the re-agglomeration to improve the cosmetic persistence.

However, conventional pigments such as ultramarine blue, blue-blue, iron oxide, manganese violet chromium oxide, chromium hydroxide, etc. are aggregated to tens of nm to hundreds of nm of particles but are aggregated for the reasons described above during storage and storage. In other words, the particles are not present as primary particles that were originally produced, but are secondary particles formed by agglomeration of several or more primary particles, and are contained in a prescription as tertiary particles formed by agglomeration of several or more secondary particles. Although it is a dispersion process in the cosmetic manufacturing process, it is not enough, and since the distribution of pigmented pigments is multi-dispersed, it does not bundle or apply effectively enough in the makeup, and it is cumbersome to apply it several times. If you don't apply it, the particles will be removed from the skin and make up the makeup lasting.

In order to improve the durability of such powders, a method of treating silicone oil, wax or copolymer to the surface of particles has been proposed. (JP-A 45-2915, JP-A 62-267213, JP-A 8-337514) ). However, surface-treated pigmented pigments may show some effects in makeup products such as two-way cakes, face powders, and foundations, where the content of extender pigments or white pigments is several times higher than that of pigmented pigments, and the range of cosmetic components is relatively limited. The above-mentioned surface-treated pigments are not preferable in eye shadows in which the content of pigments such as ultramarine, blue-blue, iron oxide, manganese violet chromium oxide, and chromium hydroxide is used from 1.0 wt% or less to several tens wt%. That is, it is not desirable to improve the sustainability of all powders included in the eye shadow cosmetics because of the problem of color expression which is one of the most important qualities. As another simple method, there is a method of improving the sustainability by adjusting the amount of the binder, but there are limitations in formulation. Increasing the content of oil and wax to improve the durability, the difference between the visible color and the actual color is remarkable, so it is difficult to express high saturation, and the Caking and Glazing occurs because the binder becomes more likely to aggregate the powder. Not desirable In particular, in the case of the use of the dark blue, the cohesion in the pigment and the relatively strong cohesion in the pigmentation, the manganese violet, etc. are used in the prescription of the increase in the amount of the binder is generated, it is difficult to expect a sufficient cosmetic effect.

The present invention has been made on the basis of the above facts, and an object of the present invention is to increase the specific surface area by increasing the specific surface area by mixing and atomizing the pigment pigment and the plate pigment as a dispersing aid and dispersing aid, It is to provide an eye shadow composition having excellent adhesion and durability while maintaining sufficient color expression by preventing re-agglomeration.

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

The eye shadow composition of the present invention is a 9: 1 in weight ratio to prevent re-agglomeration and dispersing of pigment pigments and plate pigments such as talc and mica having an average particle size of 5 to 10 μm in order to improve the adhesion and durability of the pigment pigments. ~ 5: 5 to mix, and using a jet-mill to atomize the particles using a high pressure grinding force of 6.0 bar ~ 8.0 bar to increase the specific surface area to increase the unit area in contact with the skin and prevent reagglomeration This improved the adhesion and durability.

When the mixing ratio of the pigment pigment and the anti-agglomerating agent is in the range of 9: 1 or less, the effect of inhibiting sufficient reagglomeration is insignificant, and when the mixing ratio of 5: 5 or more is excessively contained, the improvement of the effect due to the increase of the content is inefficient. It is not preferable because the content of powders other than the coloring pigments required for the prescription may be limited in the eye shadow composition containing 30.0 wt% or more of the coloring pigment. In addition, when the particle size of plate pigments such as talc and mica is 10 µm or more, the grinding force is not preferable because it is consumed in pulverizing the particles of talc and mica, rather than being transferred to the atomization of the pigment, and the particle size of talc and mica is 5 Since the particle size is smaller than 占 퐉, there is a possibility that talc and mica may be caused to self-aggregate, and thus, the role of preventing reagglomeration and dispersing aid becomes weak. The plate pigments used in the present invention are advantageously selected from synthetic pigments or natural pigments in consideration of the feeling of use and whiteness, and a pigment having a low cohesion and good whiteness among the particles themselves.

In the fine grinding process using a jet-mill, it is difficult to expect sufficient atomization effect under the grinding pressure of 6.0 bar or less, and it is not preferable.If the fine grinding is performed at a high pressure of 8.0 bar or more, the particle surface structure may cause excessive activity. It is not preferable because there is a risk of denaturation of oil and wax by surface reaction with oil and wax contained in the composition. In the composition of the present invention, the highly dispersed colored pigment having excellent makeup persistence has a small apparent density since the particles are atomized than conventional colored pigments, and because the particles of the colored pigment are not agglomerated and are highly dispersed, they are not uniformly applied when applying the skin. By applying it can exhibit an excellent cosmetic effect without the application. As the pigment before the atomization used in the present invention, in addition to the untreated pigmented pigment, an amino acid surface treatment pigment which does not cause a lot of trouble in color expression can be used for improving the feeling of use or imparting water resistance, and after the pulverization of the untreated pigmented pigment, If there is no problem in reaggregation, the surface treatment of amino acids is acceptable.

As the anti-agglomeration and dispersing aid of the present invention, in addition to talc and mica, plate pigments such as barium sulfate, plate silica, boron nitride and plate amino acid powder may also be used.

In the composition of the present invention, the highly dispersed colored pigment having excellent makeup persistence has a small apparent density since the particles are atomized than the existing colored pigments, and since the particles of the colored pigment are not dispersed and are highly dispersed, they are uniformly applied even when the skin is applied. By applying it can exhibit an excellent cosmetic effect without the application.
