Description

Pencil composition for pencils {Cosmetic composition for pencil}

The present invention relates to a pencil cosmetic composition, and more particularly to a pencil cosmetic composition excellent in usability, such as temperature stability and makeup persistence, color expression power, application characteristics, water resistance.

Pencil cosmetics are used for lip liner pencils, eye liner pencils, and eyebrow pencils.The lip liner draws along the lip line before applying lipstick, emphasizing the contours of the lips to give expression and beauty to the lips. The liner pencil is used to enhance the beauty of the eyes by drawing a line on the eyelids, which are just above the eyelashes, and the eyebrow pencil is applied to the eyebrows to make the eyebrows look thicker and to draw your favorite eyebrows. do.

Since the pencil-like cosmetic composition should be in the form of a pencil lead, the core is firm and should not be broken when applied and should be soft in use and should have excellent makeup persistence.

To this end, U.S. Patent No. 4,761,277 proposes a cosmetic composition using a mixture of a water-soluble polymer, polyvinyl alcohol and polyvinylpinolidon, for the purpose of increasing the water resistance by increasing the water resistance to a liquid type rather than a pencil form. Since it is a type, it is difficult to use in the form of a pencil. In addition, US Pat. No. 5,066,486 proposes a method for preparing lipstick or eyeliner pencil using a polymer binder composed of polytetrafluoroethylene, and US Pat. No. 5,882,683 describes inorganic components and inorganic constitutions such as bentonite and hectorite. Although eyebrows and eyeliner pencils have been proposed using pigments and the like to improve the usability and color expression, they are not effective in terms of makeup persistence.

Therefore, the technical problem to be achieved by the present invention is to solve the above problems to improve the temperature stability and at the same time to provide a pencil cosmetic composition excellent in usability, such as makeup persistence, color expression power, application characteristics, water resistance.

In order to achieve the above object, the present invention is a pencil cosmetic composition comprising a wax, fats and oils, fatty acids, pigments and film-forming component, as a film-forming agent based on the total weight of the composition polybutene, fibpy It provides a pencil-like cosmetic composition, characterized in that it comprises 0.1 to 5% by weight of at least one selected from the eicosine copolymer and mixtures thereof.

In addition, the wax component used in the pencil cosmetic composition of the present invention preferably comprises 4 to 15% by weight of lead, 0.1 to 5% by weight of carnauba lead and 0.5 to 5% by weight of microcrystalline lead based on the total weight of the composition. In addition, the fat and oil component preferably contains 5 to 20% by weight of hydrogelated vegetable oil, 1 to 8% by weight of hydrogenated castor oil, and 5 to 10% by weight of trioctanoin, based on the total weight of the composition. It is preferred to include 5 to 20% by weight of stearic acid based on the total weight of the silver composition.

Hereinafter, the present invention will be described in detail.

Pencil-like cosmetic composition is composed mostly of an oil phase component, oil phase components can be largely divided into wax components and oil and fat components.

Wax components used in pencil cosmetic compositions include vegetable waxes, animal waxes, mineral waxes, synthetic waxes and the like. Vegetable waxes include carnauba wax, candelillan wax, sugar wax, wooden wax, etc. Animal waxes include beeswax, lanolin wax, mineral wax such as paraffin, ceresin and microcrystalline lead and ozokerite, and synthetic waxes include polyethylene wax. Waxes made using the Fischer-Tropsch synthesis method, in addition to natural waxes. One or two or more of these waxes may be selected depending on the purpose of use of the pencils.

In addition, the oil or fat component of the pencil cosmetic composition may be selected from trioctanoin, amod oil, hydrogenated fish oil, hydrogenated vegetable oil, hydrogenated castor oil, etc. according to the purpose of use. .

In addition to the waxes or fats and oils, the oil-based component in the pencil cosmetic composition includes fatty acids having a long chain such as palmitic acid, stearic acid and arabic acid.

In the pencil cosmetic composition according to the present invention, wax, carnauba wax, microcrystalline lead, ceresin, and the like may be used alone or in combination thereof. Preferably, lead, carnauba lead and microcrystalline lead are used together. use. As the fatty acid, palmitic acid, stearic acid, arabic acid and the like may be used alone or in combination thereof. Preferably stearic acid is used. In addition, trioctanoin, hydrogenated vegetable oil, hydrogenated castor oil, larolin, and the like may be used alone or as a mixture thereof as a fat or oil component, preferably trioctanoin, hydrogenated vegetable oil, and Hydrogenated Fumi Free Oil is used together.

In the pencil cosmetic composition according to the present invention, the oily component is a wax component containing 4 to 15% by weight of lead, 0.1 to 5% by weight of carnauba lead and 0.5 to 5% by weight of microcrystalline lead, respectively, based on the total weight of the composition. And a fat or oil component containing 5 to 20% by weight of hydrogenated vegetable oil, 1 to 8% by weight of hydrogenated castor oil, and 5 to 10% by weight of trioctanoine, and a fatty acid component containing 5 to 20% by weight of stearic acid. It is preferable to include.

In the pencil cosmetic composition of the present invention, a pigment is generally added in order to express a color. Such a pigment may be selected from inorganic pigments, organic pigments, and pearl pigments by selecting one or two or more kinds according to the color and the concentration of the pigment. The type and content are determined, and the amount of the pigment added is preferably 1 to 45% by weight, more preferably 5 to 35% by weight based on the total weight of the composition.

Preservatives may be added to the pencil cosmetic composition according to the present invention to prevent corruption, imidazolidinyl urea, diazolidinyl urea, quaternium-15, phenoxyethanol, ethanol, potassium sorbate, paraoxybenzoic acid methyl , One or more selected from the group consisting of paraoxybenzoic acid, paraoxybenzoic acid and paraoxybenzoic acid may be used, and it is particularly preferable to use paraoxybenzoic acid methyl, paraoxybenzoic acid and butyl paraoxybenzoate together. . It is preferable that the compounding quantity of the preservative is 0.01 to 1% by weight based on the total weight of the composition.

The polybutene and / or FV eicosine copolymer added to the pencil cosmetic composition according to the present invention serves as an oil-soluble film former, and serves to improve the cosmetic sustainability of the pencil cosmetic. The amount of these used is 0.1 to 5% by weight, preferably 0.5 to 3% by weight based on the total weight of the pencil cosmetic composition. If the content is less than 0.1% by weight, the film forming agent for cosmetic persistence is insufficient. If the content is more than 5% by weight, the wax crystal structure cannot be formed, so sufficient temperature stability cannot be expected. Cannot be given. In addition, polyvinyl alcohol, polyvinylacetate, polyvinylpinolidon, ammonium acrylate copolymer, acrylate / ammonium methacrylate copolymer, acrylic / acrylate copolymer, An acrylate copolymer, an alkyl acrylate copolymer emulsion, polyquaternium-4, FV / B copolymer or FV / hexadeken copolymer may be used in an appropriate amount mixed according to the purpose of use.
