Description

Eye make-up cosmetic composition comprising high content of fiber}

The present invention relates to an eye makeup cosmetic composition containing a high content of fiber components.

Mascara is applied to the eyelashes and is used for the purpose of supplementing the shortcomings of the shape of the eyebrows or to give beauty to the eyes. In general, the conditions for mascara are to provide volume, curling power, long lash power, waterproof, etc., and apply evenly so that there is no powder spread without easily spreading to sweat, tears, and oil, and there is no burden when using. It is less likely to be contaminated with microorganisms and should be easily erased when washing face.

Such mascara is classified into a water-in-oil type, an emulsion type and a dispersant type, depending on the formulation, and the dispersant type includes an oil-dispersion type in which a pigment and a film-forming agent are dispersed in oil. Among them, the water-in-water type mascara is being developed mainly because of its ease of use.

Among the oil-in-water mascara, Long Lash Mascara is a mascara that has the function of allowing the nylon fiber component to stick to the eyelashes and make the eyelashes look longer by appropriately controlling the drying rate after the nylon fiber component contained in the cosmetic solution is applied. It is important to include a high content of fiber components.

However, the existing long lash mascara has limited use of nylon fiber content. The conventional copolymer film forming agent mainly used in the manufacture of mascara, if the nylon fiber component is used in a high content, the drying speed becomes excessively fast and the spreadability becomes rough. Rather, the nylon fiber does not stick to the tip of the eyelashes and falls off, resulting in a proper long lash. A limitation has been discovered that prevents the mascara effect from being produced.

Accordingly, there is a need to develop a composition for long lash mascara that can maximize the effect of long lash mascara, including a high content nylon fiber component while minimizing the phenomenon that the feeling of use becomes rough or the fiber component is dropped out.

In another embodiment of the present invention, the cosmetic composition is for mascara or liquid eyeliner.

The eye makeup cosmetic composition comprising the fiber component, the sub-film former, and the main film-forming agent of the present invention contains the sub-film-forming agent and the main film-forming agent in a weight ratio of 1:2 to 1:30. By including the sub-film forming agent and the main film-forming agent in the weight ratio as described above, it solves the problem of deteriorating spreadability when the fiber component is included in a high content, and has excellent long lash power including a high content fiber component. I can.

Hereinafter, the present invention will be described in detail with reference to the accompanying technology so that those of ordinary skill in the art can easily implement the present invention. However, it will be apparent to those skilled in the art that the present invention may be implemented in various different forms and is not limited to the embodiments described herein.

In the cosmetic composition for eye makeup, for the long lash power (eyelash extension effect) of mascara, it is essential to include a large amount of fiber components. However, when a large amount of fibrous components such as nylon fibers were included, a problem was found that the application property became rough during makeup and the fibers fell around the eyes after applying and became dirty. Accordingly, the present inventors completed the present invention after repeated intensive research in order to secure and improve the shortcomings of the long lash mascara formulation with reduced application properties.

The present invention has developed a long lash mascara formulation capable of stabilizing a high content of fiber components by using a mixture of acrylate/VA copolymer as a sub-film-forming agent with a film-forming agent (main film-forming agent) of the existing mascara.

Accordingly, the present invention is an eye makeup cosmetic composition comprising a fiber component, a sub-film former, and a main film-forming agent, wherein the sub-film-forming agent and the main film-forming agent are included in a weight ratio of 1:3 to 1:30. It provides phosphorus and eye makeup cosmetic compositions. The composition may include 0.1 to 10% by weight of a fiber component, 0.1 to 10% by weight of a secondary film former, and 0.1 to 30% by weight of a main film former.

In the present invention, the fiber component may be one or more selected from the group consisting of nylon-12, nylon-6, nylon-66, rayon, cellulose, and polylactic acid, and the main film forming agent is acrylate copolymer, dimethyl Aminoethyl methacrylate copolymer, acrylate, VP, ethylhexyl acrylate copolymer, styrene/acrylate/ammonium methacrylate copolymer, polystyrene, VA copolymer, octylacrylamide, butylaminoethylmethacryl Rate copolymer, methyl methacrylate crosspolymer, polyvinyl alcohol, polyacrylamide, polyurethane-14, polyethylene terephthalate, acrylate/VP copolymer, propylene copolymer, glyceryl polyacrylate, polyacrylamide, poly It may be one or more selected from the group consisting of urethane-11, and polyurethane-40.

When a large amount of nylon fibers are included using only the main film-forming agent as in the conventional mascara cosmetic composition, the spreadability becomes rough due to rapid drying of the nylon fibers, and the fibers do not adhere well to the eyelashes, resulting in a problem that the long lash function is deteriorated. It could not contain a high content of nylon fibers. In addition, when the mascara using the composition as described above is applied several times for corrective makeup, the fibers become entangled, resulting in a rather dropping phenomenon, and the long lash function is deteriorated.

Therefore, in order to solve this problem, in the present invention, as a component that can supplement the function of the main film-forming agent, an acrylate/VA copolymer having its own strong and sticky property (Tacky) is prepared together with the main film-forming agent. The content was applied to nylon fibers, and it was confirmed that the spreadability was improved and the long lash function was excellent by the use of the acrylate/VA copolymer. In addition, it was confirmed that the sub-film-forming agent and the main film-forming agent are preferably included in a weight ratio of 1:2 to 1:30. The composition of the present invention can be prepared as a mascara excellent in both spreadability and long lash function by stabilizing the drying time of a high content nylon fiber by mixing and using the secondary film forming agent and the main film forming agent in the above range.

In addition, the present invention is capable of including the fiber component and the sub-film forming agent in a weight ratio of 0.3:1 to 10:1, in an oil-in-water type mascara cosmetic composition containing a high content of nylon fibers, acrylic as a sub-film forming agent. It is possible to provide an eye makeup cosmetic composition that has a smooth application without a rough feeling by mixing the rate/VA copolymer and the main film forming agent in the above weight ratio range, and maximizing the long lash power because the nylon fiber does not easily fall off.

The composition of the present invention may contain 0.1 to 10% by weight of a fiber component. If the fiber component is included in an amount of less than 0.1% by weight, the long lash power may decrease and the drying time after application on the eyelashes may be lengthened. .

The composition of the present invention may contain 0.1 to 10% by weight of the secondary film forming agent. When the sub-film-forming agent is included in an amount of less than 0.1% by weight, the function of controlling the drying rate of the fiber component may be deteriorated, and when the sub-film-forming agent is used in excess of 10% by weight, it is excessively sticky, which may reduce the spreadability.

The composition of the present invention may contain 0.1 to 30% by weight of the main film forming agent. If the main film-forming agent is contained in an amount of less than 0.1% by weight, it may hardly act as a film-forming agent of mascara, and thus bleeding may become severe. It can reduce the adhesion of ingredients.

The acrylate/VA copolymer used in the sub-film forming agent in the present invention may be prepared and used as a base in which a solid acrylate/VA copolymer is dispersed in an aqueous phase. The acrylate/VA copolymer is contained in an amount of 10 to 30% by weight in the aqueous phase, and may be prepared through sufficient dispersion. The secondary film forming agent in which the copolymer is dispersed in more than 30% by weight may give difficulties when it is dispersed in the aqueous phase of the cosmetic composition due to excessive stickiness and agglomeration, and 10.0 to 30.0% by weight of acrylate/VA copolymer It is preferable to use a film-forming agent containing, but the form of the acrylate/VA copolymer contained in the sub-film-forming agent is not limited.

At this time, if the main film-forming agent is included in less than 3 weight per 1 weight of the sub-film-forming agent, the film-forming function itself is deteriorated and the fixing power may decrease. I may not be able to fully implement the function of controlling the drying time of the fiber component.

The cosmetic composition may be an oil-in-water emulsion formulation in which an oil phase is dispersed in an aqueous phase, which is a continuous phase, but is not limited thereto. In addition, the composition may further include additional ingredients such as wax, thickener, preservative, colorant, and solvent, and may be included without limitation as long as it is a component commonly used in cosmetic compositions. The blending amount of the additional ingredients can be easily selected by a person skilled in the art within the range not impairing the object and effect of the present invention, and the blending amount may be 0.001 to 30% by weight, specifically 0.01 to 20% by weight based on the total weight of the composition have.

In the present invention, the solvent is not limited, but preferably purified water, a lower alcohol having 1 to 4 carbon atoms, butylene glycol, propylene glycol, or glycerin may be used.

The wax may be a commonly used wax, for example, ceresin, ozokerite, paraffin, microcrystalline wax, carnauba wax, candelilla wax, polyethylene wax, lanolin wax, paraffin wax, beeswax, sugar Cross fatty acid ester, beeswax, synthetic beeswax, synthetic wax, squalane, shea butter, rice bran wax, plant seed wax, or a mixture thereof.

The thickener may be a commonly used thickener, and disteadimonium hectorite, propylene carbonate, dextrin palmitate/ethylhexanoate, polyethylene, hydroxyethylcellulose, cellulose, montmorillonite, bentonite, polyvinyl Alcohol, PVP, magnesium aluminum silicate, octylacrylamide copolymer, xanthan gum, acacia senegal gum, or a mixture thereof.

As the preservative, at least one selected from 1,2-hexanediol, caprylyl glycol, phenoxyethanol, and glyceryl caprylate may be used, and the pigment may be an inorganic pigment or an organic pigment. However, it is not limited to the above types.

The cosmetic composition of the present invention may be prepared without limitation if it is an emulsification method known in the field of the present invention. For example, an emulsion may be prepared using a homomixer, a stirrer, or the like, but is not limited thereto.

The eye makeup cosmetic composition of the present invention may be formulated with mascara or liquid eyeliner, but is not limited thereto.

Hereinafter, the present invention will be described in detail through examples. These examples are for illustrative purposes only, and it will be apparent to those of ordinary skill in the art that the scope of the present invention is not construed as being limited by these examples.
