Description

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

The present invention relates to an eye makeup cosmetic composition comprising 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 giving beauty to the eyes. In general, the conditions that mascara should have are that it gives functions such as volume, curling power, long lash power, waterproof, etc. There is little possibility of contamination by microorganisms, and it should be easily removed when washing the face.

Such mascara is divided into a water-in-oil type, an emulsion type having an oil-in-water type, and a dispersing type according to the formulation, and the dispersing formulation includes an oil-dispersion type in which a pigment and a film forming agent are dispersed in oil. Among them, the underwater type mascara is being developed mainly because of the convenience of use.

Among the oil-in-water mascaras, long lash mascara is a mascara with a function to make the length of the eyelashes look longer by attaching the nylon fiber component to the eyelashes by appropriately controlling the drying speed after the nylon fiber component contained in the cosmetic liquid is applied. It is important to include a high content of fiber components.

However, the existing long lash mascara had limitations in the use of nylon fiber content. The copolymer film former mainly used in the manufacture of conventional mascara, when the nylon fiber component is used in a high content, the drying speed is excessively fast, and the spreadability becomes rough. A limitation was found that prevented the mascara effect from being produced.

Accordingly, there is a demand for the development of a composition for long lash mascara that can maximize the effect of long lash mascara by including a high content of nylon fiber while minimizing the feeling of roughness or loss of fiber components.

The eye makeup cosmetic composition comprising the fiber component, the secondary film-forming agent, and the main film-forming agent of the present invention contains the secondary film-forming agent and the main film-forming agent in a weight ratio of 1:2 to 1:30. By including the secondary film-forming agent and the main film-forming agent in the same weight ratio as described above, it solves the problem of reduced spreadability when the fiber component contains a high content. 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 to which the present invention pertains can easily carry out the present invention. However, it will be apparent to those skilled in the art that the present invention may be embodied in various different forms and is not limited to the embodiments described herein.

For the long lash power (eyelash extension effect) of mascara in the cosmetic composition for eye makeup, it is essential to include a large amount of fiber component. However, when a large amount of fiber components such as nylon fibers are included, the application of makeup becomes rough and the fibers around the eyes fall off after application and become messy. Accordingly, the present inventors have completed the present invention after intensive research in order to secure and improve the shortcomings of the long lash mascara formulation in which the applicability is lowered.

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

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

In the present invention, the fiber component may be at least one selected from the group consisting of nylon-12, nylon-6, nylon-66, rayon, cellulose and polylactic acid, and the main film forming agent is an acrylate copolymer, dimethyl Aminoethyl methacrylate copolymer, acrylate, VP, ethylhexyl acrylate copolymer, styrene/acrylate/ammonium methacrylate copolymer, polystyrene, VA copolymer, octyl acrylamide, butylaminoethyl methacrylic Late copolymer, methyl methacrylate cross polymer, polyvinyl alcohol, polyacrylamide, polyurethane-14, polyethylene terephthalate, acrylate/VP copolymer, propylene copolymer, glyceryl polyacrylate, polyacrylamide, poly It may be at least one selected from the group consisting of urethane-11 and polyurethane-40.

When a large amount of nylon fiber is included using only the main film forming agent as in the conventional cosmetic composition for mascara, the spreadability becomes rough due to the rapid drying of the nylon fiber, and the fiber does not adhere well to the eyelashes. A high content of nylon fibers could not be incorporated. In addition, when the mascara using the above composition is applied several times for corrective makeup, the fibers are agglomerated and fall off rather than the long lash function.

In order to solve this problem, in the present invention, as a component that can supplement the function of the main film forming agent, acrylate/VA copolymer having its own firm and tacky property (Tacky) is mixed with the main film forming agent. It was applied to the nylon fiber content, 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 secondary 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 stabilizes the drying time of a high content of nylon fiber by mixing and using the secondary film former and the main film former in the above range, so that mascara having excellent spreadability and long lash function can be prepared.

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

The composition of the present invention may include 0.1 to 10% by weight of the fiber component. When the fiber component is included in less than 0.1 wt%, the long lash power may decrease and the drying time after application on the eyelashes may be prolonged. .

The composition of the present invention may contain 0.1 to 10% by weight of the bulk encapsulant. When the amount of the secondary film-forming agent is less than 0.1% by weight, the ability to control the drying rate of the fiber component may be deteriorated, and when the secondary film-forming agent is used in excess of 10% by weight, excessive stickiness may decrease the spreadability.

The composition of the present invention may contain 0.1 to 30% by weight of the main film-forming agent. When the main film-forming agent is included in less than 0.1% by weight, it hardly acts as a film-forming agent for mascara, and smearing may be severe. It may decrease the adhesion of ingredients.

The acrylate/VR copolymer used in the secondary film forming agent in the present invention may be used as a base in which the solid acrylate/VR copolymer is dispersed in an aqueous phase. The acrylate/VR copolymer is included in the aqueous phase in an amount of 10 to 30% by weight, and can be prepared through sufficient dispersion. The bulk film former in which the copolymer is dispersed in excess of 30% by weight may give difficulties when dispersed in the aqueous phase of the cosmetic composition due to excessive stickiness and agglomeration, and 10.0 to 30.0% by weight of the acrylate / VA copolymer It is preferable to use a film forming agent containing

In this case, when the main film-forming agent is included in an amount of less than 3 weight based on 1 weight of the secondary film-forming agent, the film-forming function itself may be deteriorated and the fixing force may be lowered. 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 components such as wax, thickener, preservative, pigment, 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 component can be easily selected by a person skilled in the art within a range that does not impair the purpose and effect of the present invention, and the blending amount may be 0.001 to 30 wt%, specifically 0.01 to 20 wt%, based on the total weight of the composition. have.

In the present invention, the solvent is not limited, but preferably purified water, 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, shoe It may be a cross fatty acid ester, beeswax, synthetic beeswax, synthetic wax, squalane, shea butter, rice bran wax, plant seed wax, or a mixture thereof.

The thickener can be a commonly used thickener, disteadimonium hectorite, propylene carbonate, dextrin palmitate / ethyl hexanoate, polyethylene, hydroxyethyl cellulose, cellulose, montmorillonite, bentonite, polyvinyl alcohol, PVP, magnesium aluminum silicate, octyl acrylamide 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 include an inorganic pigment or an organic pigment. However, it is not limited to the above type.

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

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