Description

[0001] Cosmetic composition for eye make-up having enhanced formability [0002]

To an eye makeup cosmetic composition having improved formability.

In case of eye make-up, it can be classified into mascara, eyeliner, shadow, eyebrow, and the like. Among them, the eyebrow is recognized as a very important factor in judging the first impression of a person, and various eyebrow makeup products are being released. Typically, the effects that the eyebrow makeup composition must have are color development, uniform spreadability, persistence that does not spread easily to sweat and oil, and is maintained for a long time.

Among the conventional eyebrow makeup products, a stick-type eyebrow formulation formulated by forming a hardness using waxes has been generally used. However, since the main component of the wax is similar to sebum, There is a problem.

Accordingly, in order to solve the above-mentioned problems, there is a need for an eye makeup cosmetic composition in which the aggregation phenomenon and the sustainability are improved as compared with the conventional eyebrow formulations.

An aspect of the present invention provides an eye makeup cosmetic composition which can be formulated into a stable and stable stick formulation by improving waxiness and durability without sacrificing waxes and having excellent moldability and is characterized in that a methyl methacrylate crosspolymer and a dipropylene glycol methyl Ether, and a method for producing the cosmetic composition.

One aspect provides a makeup cosmetic composition comprising a methyl methacrylate crosspolymer and dipropylene glycol methyl ether in a ratio of 1: 1 to 3: 1.

The makeup cosmetic composition may have improved moldability. The term "formability" refers to a degree of easiness in making a shape of a composition. If the molding is carried out with less force and less defects are generated in the molding process, moldability is good. Otherwise, moldability is poor It can be said that it is not. The makeup cosmetic composition according to one aspect has improved moldability by containing a methyl methacrylate crosspolymer and dipropylene glycol methyl ether in a ratio of 1: 1 to 3: 1.

The makeup cosmetic composition may be one for eyebrow makeup.

The makeup cosmetic composition may be formulated into a stick formulation. The stick formulations can be applied directly to the eyebrows without a separate applicator, which is advantageous in that it is simple and does not get on the hands. The makeup cosmetic composition according to one aspect of the present invention has improved moldability and can be formulated into a stick formulation.

The makeup cosmetic composition may not contain waxes. Waxes are generally included ingredients for obtaining hardness in cosmetic compositions and shaping into the desired formulation, e.g., a stick formulation. Since the wax is a component similar to sebum, there is a problem that the sustaining power is lowered when it is applied to the skin. However, the cosmetic composition according to one aspect of the present invention maintains moldability and hardness suitable for molding into a desired formulation without using wax, so that there is no problem of deterioration of the durability due to the use of waxes.

The makeup cosmetic composition may be one in which aggregation is improved.

The Methyl Methacrylate Crosspolymer is a copolymer of methyl methacrylate crosslinked with glycolide methacrylate, and is used as a synthetic film forming agent and an increasing agent (non-water soluble). It controls the viscosity of the composition with a porous polymer and adsorbs excess sebum to enhance the sustainability in make-up and the like. In addition, it forms a thin film on the surface of the skin to smoothly wrap the skin.

The methyl methacrylate crosspolymer may comprise from about 20% to about 35% by weight, or from about 22% to about 33% by weight, based on the total weight of the cosmetic composition. If the content is out of the above range, the formability is deteriorated and a desired shape can not be obtained.

The dipropylene glycol methyl ether is also referred to as methyl propylene diglycol, DPGME, or dipropylene glycol monomethyl ether.

The dipropylene glycol methyl ether is present in an amount ranging from about 1% to about 40%, from about 2% to about 35%, from about 3% to about 30%, from about 4% to about 25% %, From about 5 wt% to about 20 wt%, or from about 5 wt% to about 15 wt%. If less than about 5% by weight of dipropylene glycol methyl ether is included in the cosmetic composition, crosslinking with the methyl methacrylate crosspolymer can not be achieved. When the dipropylene glycol methyl ether is contained in the cosmetic composition in an amount exceeding about 15% by weight, it may be difficult to form a desired formulation, for example, a stick formulation, due to excessive formation of a bond with the methyl methacrylate crosspolymer.

In this composition, the content of the methyl methacrylate crosspolymer and the dipropylene glycol methyl ether is about 1% to about 55% by weight, about 10% to about 50% by weight, about 20% About 50 wt%, about 30 wt% to about 50 wt%, about 35 wt% to about 45 wt%, or about 40 wt% to about 45 wt%.

In this composition, the mixing ratio of the methyl methacrylate crosspolymer to the dipropylene glycol methyl ether may be from about 1: 1 to 3: 1, such as about 1: 1, about 2: 1, or about 3: have. If it is out of the above range, the moldability is lowered and it may be difficult to form into a desired shape.

In the above composition, the methyl methacrylate crosspolymer and the dipropylene glycol methyl ether may form crosslinks by mixing. According to one embodiment of the present invention, when the methyl methacrylate crosspolymer and the dipropylene glycol methyl ether are mixed, the two components form a physical cross-linkage. Formation of a copolymer by physical cross-linking increases moldability and has an effect of obtaining a hardness suitable for formulation into a desired formulation, for example, a stick formulation.

The cosmetic composition may further include a coloring matter. The coloring matter may include coloring pigments such as yellow iron oxide, black iron oxide, red iron oxide, ultramarine blue, ultramarine pink, ultramarine violet, chromium oxide green or a combination thereof, and extender pigments such as silica, May comprise a white pigment such as titanium dioxide, zinc oxide, or a combination thereof, such as, but not limited to, polymethyl methacrylate, talc, synthetic fluorofluorite, mica, boron nitride, nylon, have.

The coloring matter may be included in an amount of about 10% by weight to about 50% by weight based on the total weight of the cosmetic composition. If less than about 10% by weight of the coloring matter in the cosmetic composition is contained, the coloring power is poor and may not be suitable for use in makeup. When the coloring matter in the cosmetic composition is contained in an amount of about 50% by weight or more, it may be difficult to solidify and form into a stick form.

The cosmetic composition may further comprise a dispersant. The dispersant may include sorbitan stearate, phage-40 stearate, cetearyl olivate, sorbitan olivate, polyoxyethylene sorbitan fatty acid ester, dimethylpolysiloxane, sorbitan esters, or combinations thereof .

The dispersing agent may be included in an amount of about 0.001 wt% to about 5 wt% based on the total weight of the cosmetic composition.

The cosmetic composition may further comprise a fatty acid. Lauric, palmitic, stearic, behenic, lignic, isostearic, oleic, or combinations thereof. The fatty acid may be included in the cosmetic composition to be solidified to help form a hardness suitable for formulation into a stick form, for example.

The fatty acid may be present in an amount ranging from about 1% to about 40%, from about 1% to about 30%, from about 1% to about 20%, from about 1% to about 15% From about 1% to about 10%, from about 1% to about 7%, from about 3% to about 40%, from about 3% to about 30% From about 3 wt% to about 10 wt%, from about 3 wt% to about 7 wt%, from about 5 wt% to about 40 wt%, from about 5 wt% to about 30 wt%, from about 3 wt% to about 15 wt% From about 5 wt% to about 20 wt%, from about 5 wt% to about 15 wt%, from about 5 wt% to about 10 wt%, or from about 5 wt% to about 7 wt%.

The cosmetic composition may further contain additional components commonly used in cosmetics such as purified water, a moisturizing agent, an emulsifier, a thickening agent, a dispersant, a colorant, a flavoring agent, a filler, a preservative, an antiseptic, a neutralizing agent, a sunscreen agent, a sweetener, Radical scavengers, metal ion sequestrants, and mixtures thereof. ≪ RTI ID = 0.0 > [0031] < / RTI >
