Hereinafter, preferred embodiments of the present invention will be described in order to explain the present invention more specifically. However, the present invention is not limited to the embodiments described herein but may be embodied in other forms.

The present invention provides a makeup cosmetic composition comprising pearl particles, a powder and a binder, wherein the binder is a gel binder comprising a gel and an oil.

Each of the core components used in the production of the present invention will now be described in more detail.

Gel binder

In the makeup cosmetic composition containing a high amount of the gel and the oil of the present invention, the gel binder may be contained in an amount of 40 to 60% by weight based on the total weight of the composition. In addition, the gel binder may contain 50 to 90% by weight of gel and 10 to 50% by weight of oil based on the total weight of the gel binder.

In order for the composition of the present invention to have excellent persistence, adhesion, spreadability and moldability, which are desired effects of the present invention, it is important to select the content and type of the gel and the oil constituting the gel binder in the composition of the composition. In the present invention, the gel binder is preferably contained in an optimal amount to suppress the problems of uniform binding between the pearl and the powder and stability of the molding, difficulty in kneading, breakage of the contents during compression and molding, .

A high content of gel and oil is added to the composition of the present invention, so that the formability of the spherical powder can be enhanced and the makeup sustainability can be improved.

Gel

The gel enhances the stability of the formulation by increasing the binding force between the powders and enhances the makeup sustainability. The gel can be included in the gel binder in an amount of 50 to 90% by weight based on the total weight of the gel binder.

If the content of the gel is less than 50% by weight, the stability of the formulation may deteriorate and the oil may be separated, and the formability may be deteriorated and the formulation may be easily crushed during application. Also, the surface may become hard and the contents may not be able to be taken, and the oil content may be relatively high during application, which may cause problems between the wrinkles. If the content of the gel exceeds 90% by weight, the stability of the formulation and the stability of the formulation may be improved, but the contents may not easily float and may not be well-formed.

The gel may include a silicone-based gel, a hydrocarbon-based gel, or a mixture thereof, and may preferably include a silicone-based gel and a hydrocarbon-based gel having a weight ratio of 1: 0.5 to 2.

The reason for including both the silicone-based gel and the hydrocarbon-based gel as described above is that the gels do not mix with each other, so that the pearl particles do not adhere to each other smoothly and smoothly, can be smoothly applied on the skin, and the attachment characteristics and the sustainability characteristics can be uniformly displayed.

The silicone-based gel may be a silicone polymer alone or a mixture of two or more silicone polymers that exhibits a gel state, and may be selected from the group consisting of dimethicone, polysilicon-11, polysilicon-15, polysilicon- And may include one or more selected from 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, and Dow Corning EL-8050ID Silicone Organic Elastomer Blend. However, it is possible to apply a silicone gel raw material specially prepared according to the requirements of those skilled in the art, It is not.

The hydrocarbon-based gel is a polymeric copolymer, which can impart elasticity to cosmetic compositions and is produced by dispersing an ethylene / propylene / styrene copolymer or a butylene / ethylene / styrene copolymer in an isoparaffin or isopropyl palmitate solvent .

The hydrocarbon gel may be, for example, VERSAGEL M500 or ME500 or MP750 series of Penreco, but is not limited thereto. Polybutene or polyisobutene may also be added to improve molding stability and adhesion to the skin and impart gloss.

oil

The oil penetrates between the powders to maintain the cosmetic composition in a high viscosity state and to improve moldability and sustainability. The oil may be contained in the gel binder in an amount of 10 to 50% by weight based on the total weight of the gel binder have.

If the oil content is less than 10% by weight, the adhesion and durability of the pearl is lowered. If the oil content is more than 50% by weight, the pearl adhesion is improved. However, And the formation of pearls occurs, and the formulation may be changed into a slurry, or the formulation may be prepared in a fluid state in which it is fluid.

The oil may include at least one selected from the group consisting of a hydrocarbon-based oil, a silicone-based oil, an ester-based oil, and a mineral-based oil, and preferably includes a silicone oil and a hydrocarbon oil at a weight ratio of 1: can do.

The reason for including both the silicone oil and the hydrocarbon oil as described above is that they can smoothly take the composition owing to the property that they are not mixed with each other and can exhibit smooth and uniform application without clumping upon application of pearl particles.

Wherein the silicone oil is selected from the group consisting of dimethicone, cyclomethicone, cyclophenylmethicone, caprylimethicone, caprylyl trimethicone, caprylylmethicone, cetearylmethicone, hexadecylmethicone, hexylmethicone, But are not limited to, chitosan, chicone, myristylmethicone, phenylmethicone, stearylmethicone, stearyl dimethicone, trifluoropropylmethicone, cetyl dimethicone, polyphenylmethylsiloxane, dimethylpolysiloxane, methylphenylpolysiloxane, cyclopentasiloxane, At least one member selected from the group consisting of polytetrafluoroethylene, polytetrafluoroethylene, pentasiloxane, cyclohexasiloxane, cycloheptasiloxane, cyclotetrasiloxane, cyclotrisiloxane, methyltrimethicone, diphenylsiloxyphenyltrimethicone, caprylylmethicone and phenyltrimethicone . ≪ / RTI >

In addition, the hydrocarbon-based oil may include at least one selected from the group consisting of isohexadecane, isodecane, undecane, squalane, hydrogenated polydecene, alpha olefin oligomer, and hydrogenated polyisobutene.

powder

In the makeup cosmetic composition containing a high amount of gel and oil of the present invention, the powder may be coated or uncoated, and may be contained in an amount of 10 to 30% by weight based on the total weight of the composition.

When the content of the powder is less than 10% by weight based on the total weight of the composition, it may become an oil-dispersed formulation in the form of oil dispersion type, There is a disadvantage that the oil content is relatively low and the moisture property, which is similar to the general fact composition, is low, dry, does not show persistence, or does not pay off due to caking .

The above-mentioned caking phenomenon means that the powder changes in a hard and hard form due to heat, pressure, and moisture, and the pay-off refers to the cosmetic material being buried in the makeup tool to be used.

The components of the powder used in the present invention may further include extender pigments, pigments and white pigments commonly used in makeup products, and specifically include silica, polymethyl methacrylate, polyurethane, But is not limited to, a spherical powder including at least one selected from the group consisting of silane, silicone elastomer powder, and nylon.

In the case of using the spherical powder, the spreadability of the cosmetic composition is generally improved, but the formability is lowered and the use thereof may be restricted. However, since the makeup cosmetic composition of the present invention contains a high amount of gel and oil, the formability, spreadability and pay-off characteristics of the spherical powder can be improved.

Further, the powder may be a translucent powder having a low refractive index, and therefore it is preferable that the powder does not affect the color of pearl or the like.

Pearl particles

In the makeup cosmetic composition containing a high amount of gel and oil of the present invention, the pearl particles may be coated or uncoated, and may be contained in an amount of 20 to 40% by weight based on the total weight of the composition.

If the pearl content is less than 20 wt%, the shimming effect or sparkling effect may not be sufficiently exhibited. If the pearl content is more than 40 wt%, the pearl is not stably attached due to the lack of the binder. It is possible to cause a severe flaking of powder during use.

The pearl particles may include at least one selected from the group consisting of mica, synthetic mica, alumina, borosilicate, boron nitride powder, talc and sericite.

Preferably, the pearl particles are wet-pulverized and have an average particle size of 10 to 100 μm and an aspect ratio of 60 to 120. If the average particle size is less than 10 mu m, the whitening phenomenon occurs and the transparency deteriorates. If the average particle size is more than 100 mu m, the particles are rough and thus not suitable for use in cosmetics. In addition, when the intestinal expense is less than 60, there is a disadvantage in that the skin adhesion property is lowered and inherent gloss is lowered. On the other hand, when it is more than 120, I do not.

The pearl particles may be coated with one or more selected from the group consisting of titanium dioxide, tin oxide, and iron oxide.

The pearl particles are preferably a synthetic mica coated with mica and titanium dioxide coated with titanium dioxide.

The mica perlot coated with titanium dioxide is commercially available from Engelhard of flamencosin pearl, flamenco satin 120T, flamenco velvet, Such as flamenco superpearl, flamenco pearl, flamenco ultra silk, Timica silver sparkle, Timica pearl white, And a timica extra large sparkle.

In addition, synthetic mica perlot coated with titanium dioxide is commercially available from Sky chemical, cosmetica super white, cosmetica silver white, cosmetica mirror white, .

The makeup cosmetic composition may have a hardness of 0.3 to 1.0 dyne / cm ² . Less than 0.3 dyne / cm ^2, if it is too weak, cosmetic composition (mainly NBR puff) or hand makeover may be excessively buried. If it is too hard to exceed 1.0 dyne / cm ^2, the cosmetic composition may easily be buried.

The composition according to the present invention may have conventional formulations. For example, the compositions of the present invention may be formulated into eye shadows, primers, blushers, eye makeup bases, makeup bases, and foundations, and the like. 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.

The present invention includes additives for enhancing physical properties and improving the quality of a cosmetic composition, and the additive may further include a coloring matter, an antiseptic, an emulsifying agent, a dispersing agent or an aging agent.
