Description

Mascara cosmetic composition {COSMETIC COMPOSITION OF MASCARA}

[TECHNICAL FIELD OF THE INVENTION]

The present invention relates to a mascara cosmetic composition, and more particularly, to a mascara cosmetic composition having excellent volume and curling without forming a uniform coating film, and having excellent feeling of use, application and adhesion, and no feeling of burden after application.

[Private Technology]

Mascara is applied to the eyelashes to thicken and thicken the eyelashes, emphasizing the outline of the eyes, and used for the purpose of giving expression and beauty to the eyes. Conventional mascara has to be applied to the eyelashes, so there should be no irritation to the eyes, apply evenly so that there is no residue or powder blowing, and it should be excellent in curling effect without being buried under the eyebrows after application because of fast drying speed. In addition, the eyelashes are not tangled or easily spread to sweat, tears and oil, and the color expression is excellent, there is no burden when using, less likely to be contaminated with microorganisms, and should be easily removed when washing.

Mascaras can be broadly classified into solid, emulsified and solvent forms. Solid mascara is the oldest form of mascara, in which the pigment is mixed and molded into a wax containing tie-stearate and applied to the eyelashes using a wet brush. However, solid mascara has a disadvantage in that a tie-stearate forms soap (Soap) and easily spreads to sweat and tears. Solvent-type mascara is a product made of volatilized C _10-15 hard isoparaffin, low molecular weight chain type silicone oil, or low degree of polymerization cyclic silicone oil, in which waxes and pigments are added. While there are excellent features, eye irritation and drying speed are easy to bury, and there is a disadvantage to use an oil base remover when erasing. Emulsified mascara is a product that adds pigment to general emulsified products, and it is more convenient to use than solid mascara by using a spiral brush, but there is still a problem of bleeding to sweat and tears. In order to solve the drawbacks of the mascara described above, there is a polymer emulsified mascara that is imparted with water resistance and curling effect by adding a polymer film-forming agent, and this formulation is currently used by most of the mascara used.

Polymer emulsifying mascara consists of water-soluble / soluble film-forming agent to improve curling and sustainability, inorganic pigment for color expression, wax and oils, pigment dispersant for emulsifying oil-soluble component and water-soluble component and dispersing inorganic pigment. And surfactants such as emulsifiers. However, the above-mentioned polymer emulsion type mascara takes an emulsified form in the formulation, but contains a large amount of water and oil-soluble film-forming agents for the purpose of functioning, and the viscosity and hardness continue to increase with time after manufacture, causing the contents to harden. This causes not only agglomeration but also a problem of deterioration in curling, volume and adhesion.

In order to solve the above problems, an object of the present invention is to provide a mascara cosmetic composition that is effective for curling the eyelashes by forming a smooth and uniform coating film.

In addition, an object of the present invention is to provide a mascara cosmetic composition that can minimize changes over time and eye irritation.

It is another object of the present invention to provide a mascara composition having excellent usability, applicability, and durability.

In order to achieve the above object, the present invention provides an emulsifier selected from the group consisting of (a) wax, (b) fatty acid, (c) triethylhexanoin, olive oil derived emulsifier, and mixtures thereof, (d) water soluble thickener It provides a mascara cosmetic composition comprising (e) a film former and (f) a pigment.

Hereinafter, the present invention will be described in detail.

The present invention while studying a method for forming a heavy wax coating film, which is a disadvantage of the conventional mascara composition in a smooth, uniform form, using the emulsifier derived from triethylhexanoin or olive oil as an emulsifier to solve the above problems It was confirmed that the solution can be completed the present invention.

The mascara cosmetic composition of the present invention contains an oil phase component, an emulsifier, a water-soluble thickener, a film former, and a pigment, and includes waxes and fatty acids as oil phase components. In addition, the mascara cosmetic composition may further include components used in moisturizers, purified water, preservatives or conventional eye cosmetic compositions.

The wax (a) may be selected from the group consisting of vegetable waxes, animal waxes, mineral waxes, synthetic waxes, natural waxes and mixtures thereof. Examples of vegetable waxes include carnauba wax, candelillan wax, sugar wax, and lead wax; animal waxes include beeswax and lanolin wax; examples of mineral waxes include paraffin, ceresin, microcrystalline lead and ozokerite. Examples of synthetic waxes include waxes made through polyethylene wax and Fischer-Tropsch synthesis. Preferred waxes of the present invention are selected from the group consisting of beeswax, carnauba wax and mixtures thereof. The content of the wax is preferably 0.1 to 30.5% by weight of the mascara cosmetic composition, more preferably 1 to 25.5% by weight. If the content of the wax is less than 0.1% by weight, the viscosity is too low, and if it exceeds 30.5% by weight, the viscosity may be excessively increased to form a heavy wax coating film.

Fatty acid (b) of the present invention may be used alone or in the form of a mixture of fatty acids having a long chain, such as palmitic acid, stearic acid, arabic acid, preferably stearic acid. The fatty acid content is preferably 0.1 to 15% by weight of the mascara cosmetic composition, more preferably 0.5 to 10% by weight. When the amount of fatty acid in the mascara cosmetic composition is less than 0.1% by weight, the viscosity of the composition may be lowered, and when it exceeds 15% by weight, the viscosity may be excessively increased, resulting in unsatisfactory feeling.

The emulsifier of (c) of the present invention is used for solving the problem of heavy and thick wax coating film formed on the eyelashes due to the use of wax and the problem caused by the change over time of the composition. The emulsifier may be selected from the group consisting of triethylhexanoin, olive oil-derived emulsifiers and mixtures thereof, preferably triethylhexanoin and olive oil-derived emulsifiers, respectively, from 0.1 to 3% and 0.1 to 3% of the mascara cosmetic composition. It is used at 3% by weight. Olive oil derived emulsifiers include cetearyl olivate or sorbitan oleate. When the content of triethylhexanoin is less than 0.1% by weight, it may be difficult to form the wax coating layer smoothly and uniformly. When the content of the triethylhexanoin is more than 3% by weight, it may be effective in changing valineness and aging, but it may become messy under use. In addition, when using an olive oil-derived emulsifier less than 0.1% by weight, it may be difficult to form a wax coating film smoothly and uniformly. When it exceeds 3% by weight, the stability against aging changes, but the eyelashes become heavy and aggregation may occur. have.

(D) The water-soluble thickener of the present invention is used for the purpose of forming a uniform makeup film and stabilizing a phase without forming an irreversible film film. The water soluble thickener may be selected from the group consisting of acacia gum, xanthan gum, carginine, magnesium aluminum silicate, hydroxyethyl cellulose, hydroxypropyl cellulose, carboxymethyl cellulose, cellulose derivatives and mixtures thereof, the content of mascara Preference is given to 0.05 to 15% by weight of the cosmetic composition. When the content of the water-soluble thickener is less than 0.05% by weight, it is difficult to sufficiently perform the role as a thickener, and when the content of the water-soluble thickener is more than 15% by weight, the clumping of the eyelashes may be severe and hard to give a clean makeup effect. More preferred content of the water soluble thickener is from 0.1 to 10% by weight.

The film forming agent (e) of the present invention is one of the important components of the mascara composition as a component for forming a film film. Film formers generally include polyvinyl alcohol, polyvinylacetate, polyvinylpyrrolidone, ammonium acrylate copolymers, FV / Eicosine copolymers, acrylic / acrylate copolymers, and acrylate copolymers. , Alkyl Acrylate copolymer emulsion, hydroxyethylcellulose dimethyldiallylammonium chloride copolymer (Hydroxyethylcellulose Dimethyldiallyammonium Chloride Compolymer, trade name: Polyquaternium-4) and mixtures thereof. Preferably, polyvinyl alcohol, acrylate copolymer or alkyl acrylate copolymer emulsion is used to form a non-sticky and uniform film film. The amount of film former used is 0.5 to 35% by weight of the mascara cosmetic composition. More preferably 1 to 25% by weight relative to the total weight of the mascara composition. If the amount of the film-forming agent is less than 0.5% by weight, the film film may not be formed, and when the amount of the film-forming agent is more than 35% by weight, the uniform film film may not be formed and a thick film film may be formed.

The pigment (f) of the present invention may be selected from one or more types according to the color and the concentration of the color to be made from an inorganic dye, an organic dye and a pearl dye, and the type and content thereof may be determined. The pigment used in the present invention is 1 to 25% by weight of the mascara cosmetic composition, more preferably 5 to 15% by weight. If the amount of the dye used is less than 1% by weight, the color may not appear due to the addition of the pigment, it is not economical to use more excess since only 25% by weight is sufficient effect appears.

In addition to the components mentioned above, the mascara cosmetic composition of the present invention may further comprise purified water, humectants, preservatives or mixtures thereof.

The purified water may be appropriately included in the form of mascara. That is, the content may vary depending on whether it is in the form of cake or powder, in water, or in water-in-water mascara. When the composition of the present invention has the form of water type mascara, the content of purified water is preferably 30 to 60% by weight.

The moisturizing agent may use various kinds of those commonly used in eye cosmetics, and such moisturizing agents include glycerin, 1,3-butylene glycol, propylene glycol, DL-panthenol, sorbitol, glycol distearate, and sorbitol hydroxy stearate. Rates, or mixtures thereof. In particular, by using 1,3-butylene glycol, propylene glycol, DL- panthenol can be used by selecting one or more kinds according to the feeling and moisturizing power. The amount of moisturizer is 0.1 to 10% by weight based on the total weight of the total composition. If the amount of the moisturizer is less than 0.1% by weight, the moisturizing effect is not sufficient, and using only 10% by weight results in a sufficient moisturizing effect. Therefore, it is not required to use an excessive amount.

The preservative may be any preservative commonly used in mascara compositions, for example, imidazolidinyl urea, diazolidinyl urea, quiternium-15, phenoxyethanol, ethanol, potassium sorbate, paraoxybenzoic acid Methyl, butyl paraoxybenzoate, propyl paraoxybenzoate and ethyl paraoxybenzoate.
