Description

Cosmetic composition

The present invention relates to a cosmetic composition, and more particularly to a cosmetic composition having improved stability and dispersibility by using any one or two or more co-solvents selected from isopropyl alcohol and polyol and C6-C20 isoparaffin.

Recently, the number of women wearing makeup is increasing rapidly due to the increase of social activities of women, and accordingly, various demands on cosmetics are increasing.

Makeup cosmetics generally consist of oily ingredients, powders, waxes, and aqueous ingredients.

Powders, which are one of the components of the makeup cosmetics, are indispensable ingredients, and are used to cover color imperfections and skin defects, and include talc, mica, sericite, boron nitride, nylon and silica. , Sieving pigments such as polymethyl methacrylate, titanium dioxide having excellent hiding power of skin defects, white pigments such as zinc oxide, vegetable powders such as lamicellulose or velvet, iron oxides such as black iron oxide, and sensitizing Yellow pigments such as aluminum lake, chromium oxide, ultramarine, legal tar pigments, etc. can be classified into coloring pigments.

Depending on the type of powder included in the makeup cosmetics, agglomeration may occur due to reagglomeration, or the adhesiveness may be degraded, thereby degrading the persistence of the makeup and reducing the moldability of the powder.

In addition, there are various problems in the process of manufacturing makeup cosmetics.

The press process is a compression method using oil and wax as a binder, and generally the binder content is limited. This has a disadvantage in that when the excess binder is contained, the payoff and spreadability are reduced due to the hardness increase of the product, and the powder is not evenly dispersed. In the case of using excessive amount of pearl, the pearl effect is lower than the content of used pearl.In case of using excess oil as binder to secure moldability, stain or crack may occur on the surface of molding.

On the other hand, the powder produced by the wet process has the advantage of evenly dispersing the powder without a caking phenomenon even if the binder is used in an excessive amount, but has a disadvantage of reducing the stability of the formulation, the cracking phenomenon may occur during the drying process .

Korean Patent Publication No. 2009-0126031 proposes a method of using water-in-oil emulsion as a binder to solve the hard texture and powder blowing of an existing press formulation at the same time, but there is still a need for research on cosmetic compositions suitable for various needs. .

The present invention relates to a cosmetic composition, and more particularly, to a cosmetic composition comprising a powder mixture containing a powder component, isopropyl alcohol and a cosolvent.

The present invention provides a cosmetic composition, and in particular, provides a makeup cosmetic composition having improved dispersibility and stability while improving skin adhesion and glossiness.

The cosmetic composition of the present invention comprises a powder mixture containing a powder component, isopropyl alcohol, and a cosolvent, wherein the cosolvent is any one or two or more selected from polyol and C6-C20 isoparaffin.

Polyol according to an embodiment of the present invention may be inositol, mannitol, xylitol, glycerin, sorbitol, pentyl glycol, 1,3-butylene glycol, propylene glycol, dipropylene glycol or glycerin, C6-C20 isoparaffin is C7 -8 isoparaffin, C8-9 isoparaffin, C9-11 isoparaffin, C9-13 isoparaffin, C9-14 isoparaffin, C10-11 isoparaffin, C11-12 isoparaffin, C11-13 isoparaffin, C12-14 Isoparaffin, C13-14 isoparaffin or C13-16 isoparaffin.

Isopropyl alcohol and co-solvent according to an embodiment of the present invention may be 30 to 80% by weight based on the total cosmetic composition, isopropyl alcohol and co-solvent may be a weight ratio of 7 to 9.5: 3 to 0.5.

The cosolvent according to an embodiment of the present invention may be a mixed solvent of polyol and C6-C20 isoparaffin, and the polyol and C6-C20 isoparaffin may have a weight ratio of 4 to 7: 6 to 3.

The powder component of the powder mixture according to one embodiment of the present invention may be talc, silica, organic spherical powder, iron oxide and pearl, and may further include a binder component.

The cosmetic composition of the present invention is excellent in dispersibility and very high in volume adhesion, touch and glossiness.

In addition, the cosmetic composition of the present invention does not have any stains or cracks on the surface during the formulation, high molding stability and less powdering.

The present invention can be formulated in a variety of processes, and provides a cosmetic composition having high skin adhesion, touch and color development, and high molding stability.

The cosmetic composition of the present invention comprises a powder mixture containing a powder component, isopropyl alcohol, and a cosolvent, wherein the cosolvent is any one or two or more selected from polyol and C6-C20 isoparaffin.

Cosmetic composition of the present invention by using isopropyl alcohol as the main solvent and using any one or two or more co-solvents selected from polyol and C6-C20 isoparaffin, low dispersibility and gloss in the conventional press process It can be overcome.

Specifically, the general press process has limited the content of the binder because it has a disadvantage in that the payoff and spreadability is lowered and the powder is not evenly dispersed by increasing the hardness of the product when the excess binder is contained. Due to the limitation of the binder content, even if an excess of pearl is used, the pearling effect is lowered. Also, when an excessive amount of oil is used as the binder to secure moldability, stains or cracks are formed on the surface of the molding.

Therefore, the wet process was proposed as a process to compensate for the disadvantages of the press process, and in the case of the product manufactured by the wet process, even if the binder is used in excess, the powder can be dispersed evenly without the caking phenomenon, the pearly feeling can be realized, and the smooth texture can be realized. However, the formulation stability is low, there is a disadvantage that the cracking phenomenon occurs when drying.

Therefore, the present invention uses the isopropyl alcohol as the main solvent to overcome the disadvantages while maintaining the advantages of the wet process and by using a co-solvent with one or two or more solvents selected from polyol and C6-C20 isoparaffin. I tried to overcome the same disadvantages.

By using isopropyl alcohol as the main solvent, it maintained the advantage of easily evaporating without leaving a stain on the surface of the formulation, and improved the stability of the formulation by reducing the porosity in the powder, it was possible to minimize the powder during the payoff.

In addition, the present invention by using at least one solvent selected from polyol and C6-C20 isoparaffin with the main solvent isopropyl alcohol as a cosolvent during the stability and drying process of the formulation due to the high volatilization rate of isopropyl alcohol as the main solvent The breakthrough has been mitigated.

Preferably the cosmetic composition of the present invention may be for wet process and injection process.

As the cosmetic composition for the wet process or the injection process of the present invention is applied to the wet process and the injection process, the powder is evenly dispersed without a caking phenomenon even when the binder is used in an excessive amount, and the powder including pearl by isopropyl alcohol and a cosolvent Particles are rearranged to have a high pearl effect in appearance compared to the injected pearl content, and have a soft texture due to the voids between powders generated by the moisture absorption process.
