Definitions

• 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.
• 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.
• 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.
• 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.
• 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 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.
