Description

W / O Type Eye Make-up Cosmetic Composition}

The present invention relates to a water-in-oil type eye cosmetic composition, and more particularly, to a water-in-oil type eye cosmetic composition having excellent water resistance and improved makeup durability.

The mascara is applied to the eyelashes to curl the eyelashes for a long time and give volume to the eyes. Eyeliner is also used to make the outline of the eyes darker to make the eyes more distinct. In particular, Asian women who have poorer eyelashes and smaller eyes than Western women have a great desire to emphasize their eyes by using makeup using mascara or eyeliner.

Eye cosmetic cosmetic compositions, such as mascara or eyeliner, should be free of eye irritation, dry quickly and free from smearing under the eyebrows immediately after application, and the eyelashes are entangled or smeared easily by sweat, tears, and oil. It should be applied uniformly so that there is no powder blowing, and it is desirable to have the effect of being easily erased at the time of washing.

Generally, the cosmetic composition for eye cosmetics can be broadly divided into an emulsion type, a coating type, an emulsion coating type, an oil type, and an oil coating type. The emulsified type is an oil-in-water type formulation containing the solid, semi-solid, liquid oil, and water based as main components. This type of emulsification is easy to remove from moisture, sweat, tears, and the like, and the contents of mascara applied to the sebum component and other cosmetic oils around the eyes are smeared, and the circumference of the eyes becomes messy over time. In addition, the film type has been used as a film forming agent, a natural emulsion or a polymer emulsion by emulsion polymerization using a water-soluble polymer or an emulsifier, but this formulation can not obtain sufficient water resistance as a cosmetic because of poor water resistance of the polymer material itself. On the other hand, the oil type is composed of solid, semi-solid, liquid oil and volatile hydrocarbon system, which has a disadvantage in that water resistance is good while oil resistance or dryness is very poor.

Since most of Korean women have thin eyelashes under them, when they use the commonly used underwater-type wash-off mascara, the lower part of the eye becomes black after a certain period of time. Will inhibit the effect. In addition, frequent outside activities and increased leisure time increased the exposure to sweat and water. Therefore, in recent years, in order to prevent mascara from spreading under various circumstances, a mascara having a water-proof mascara or a resin is used to give a little water-proof function or a water-in-oil type and oil-dispersed water proof function. Has been proposed a lot.

When the acrylate emulsion is blended with the oil-in-water type film forming agent, a water resistance effect is obtained, but it is difficult to expect a perfect water repellent effect such as sports or leisure due to the emulsifier component in the acrylic lace emulsion. In addition, conventional water-in-oil type and oil-dispersed mascara are difficult to apply an acrylate emulsion that is not stable at high temperatures in the manufacturing process, so acrylate / behenylacrylate / dimethicone methacrylate copolymer and acrylate / dimethicone copolymer are used. However, the water-resistant effect is excellent, but the drying speed is slow, it takes a long time during makeup, and the oil resistance due to oily components such as skin sebum is not good, so there is a phenomenon that the phenomenon of smearing under the eyes is caused by frequent blinking of eyes.

Therefore, there is a demand for the development of a cosmetic composition for eye cosmetics that meets both water resistance and oil resistance at the same time and has strong persistence in both water and sebum.

In order to solve the above problems, an object of the present invention is not only to have an excellent makeup function such as curling power and a sense of volume, but also excellent in both oil resistance and oil resistance to improve bleeding caused by moisture or sebum, and thus improve eye makeup persistence. It is to provide a cosmetic cosmetic composition.

In order to achieve the above object, the present invention

Provided is a water-in-oil type cosmetic composition for water-in-oil type eye cosmetics in which an aqueous phase containing an aqueous solution of an acrylate-based copolymer is dispersed as a film forming agent in an oil phase including a hydrogenated rosinate ester gum as a wax.

The cosmetic composition for eye cosmetics of the present invention is excellent in both water resistance and oil resistance to have improved makeup persistence as well as excellent makeup functions such as volume and curling power.

Hereinafter, the present invention will be described in detail.

In general, an acrylate copolymer is used as a film forming agent in eye cosmetic composition. For example, in the oil-in-water composition, an acrylate emulsion obtained by dispersing an acrylate copolymer with an emulsifier is used in the water phase, and the water-in-oil type composition has an acrylate / behenyl acryl phase in the oil phase instead of an acrylate emulsion having low stability at high temperatures. The rate / dimethicone methacrylate copolymer and the acrylate / dimethicone copolymer are used.

However, in the case of the oil-in-water composition using the acrylate-based emulsion, water repellency is lowered due to the emulsifier component included in the emulsion, and in the water-in-oil-based composition using the acrylate-based copolymer, oil resistance to sebum is poor and makeup persistence is not good. There are disadvantages.

In order to solve this problem, in the present invention, the acrylate copolymer is uniformly dissolved, and the aqueous solution of the acrylate copolymer which is stable at a high temperature of 70 ° C. or higher is provided in the water phase to impart oil resistance, and the hydrogenated rosinate having a high softening point in the oil phase. It contains a system ester gum to impart cosmetic functions such as water resistance and volume and curling power.

Specifically, the cosmetic composition for eye cosmetics according to the present invention is dispersed in an aqueous phase containing an aqueous solution of an acrylate-based copolymer as a film-forming agent in an oil phase containing a hydrogenated rosinate ester gum.

The cosmetic composition is a water-in-oil emulsion in which an aqueous phase is dispersed in a continuous phase.

In this case, the present invention contains a hydrogenated rosinate ester gum.

The hydrogenated rosinate ester gum has a high melting point of 102 to 110 ° C. and is not particularly limited as long as it is used in a conventional cosmetic composition. Preferably pentaerythrityl hydrogenated rosinate, glyceryl hydrogenated rosinate and mixtures thereof are used.

At this time, the hydrogenated rosinate ester gum is included in an amount of 1.0 to 15.0% by weight of the total composition. If the content of the hydrogenated rosinate ester gum is less than the above range, it is difficult to expect the water and oil repelling effect due to the low content of the ester gum. On the contrary, if the content exceeds the above range, the viscosity is excessively increased, resulting in poorly used feeling and poor stability. There is a problem.

In addition to the hydrogenated rosinate ester gum, it may further contain a wax commonly used in eye cosmetic composition. In one example, carnauba wax, candelilla wax, polyethylene wax, lanolin wax, paraffin wax, beeswax, sucrose fatty acid esters, microcrystalline wax, or mixtures thereof are possible.

At this time, the wax is included in the content of 1.0 to 20.0% by weight of the total composition. If the content of the wax is less than the above range there is a problem that can not exhibit the cosmetic function, on the contrary, if it exceeds the above range there is a disadvantage that it is difficult to remove during cleaning.

As the oil phase component, a volatile oil may be used, and the oil is not particularly limited in the present invention, but typically, dimethylpolysiloxane, cyclomethicone, C10-11 isoparaffin, isododecane, isohexadecane, and the like. This is possible.

At this time, the volatile oil is included in the content of 5.0 to 30.0% by weight of the total composition. If the content of the volatile oil is less than the above range, the applicability of the cosmetic composition is lowered, on the contrary, if it exceeds the above range, there is a problem that the stability of the water-in-oil emulsion is lowered.

The oil phase may further include oil-based thickeners, emulsifiers, pigments and powders as additives in addition to the hydrogenated rosinate ester gums, waxes and volatile oils. Since these components are well known in the art, a detailed description thereof will be omitted. At this time, the additive is preferably contained in 20.0 to 40.0% by weight of the total composition. This content is limited to the range for securing the effect to be obtained in the present invention as well as the purpose of the function of the cosmetic composition and the preparation of the composition according to the present invention.

The oil phase is preferably contained in 50.0 to 99.0% by weight of the total composition.

The aqueous phase dispersed in the oil phase described above contains an acrylate copolymer aqueous solution as a film forming agent.

The aqueous phase includes an acrylate-based copolymer aqueous solution and the remainder of the purified water.

At this time, the acrylate-based copolymer aqueous solution is contained in 1.0 to 30.0% by weight of the total composition. If the content of the aqueous solution of the acrylate-based copolymer is less than the above range, it is difficult to obtain the effect of adding the film-forming agent, on the contrary, if the content exceeds the above range, the viscosity is excessively increased, resulting in poor usability.

The acrylate-based copolymer aqueous solution of the present invention is an acrylate-based copolymer uniformly dissolved in purified water and polyhydric alcohol using polyethylene glycol fatty acid ester as a solubilizer.

The polyhydric alcohol is not limited in the present invention as long as the acrylate copolymer can be uniformly dispersed. For example, one selected from the group consisting of propylene glycol, diethylene glycol, triethylene glycol, dipropylene glycol, butylene glycol, hexylene glycol, polyethylene glycol, and polypropylene glycol is possible.

The polyethylene glycol fatty acid ester may be polyethylene glycol C14 to C18 fatty acid ester. Particularly, in the present invention, when using ceteth-25 in polyethylene glycol fatty acid ester, the acrylate copolymer is effectively solubilized in purified water and polyhydric alcohol, thereby forming a stable aqueous solution at high temperature.

The acrylate-based copolymer aqueous solution is 0.5 to 30% by weight of the acrylate-based copolymer; 0.5 to 1.0 weight percent polyethylene glycol fatty acid ester; 0.5-50.0 wt% polyhydric alcohol; And the remainder of the purified water. At this time, the polyhydric alcohol is included in the content of the acrylate copolymer or more, and the polyethylene glycol fatty acid ester is preferably contained in 0.5% by weight or more based on the content of the acrylate copolymer.

If the content of the acrylate-based copolymer is less than the above range it is difficult to expect the oil resistance imparting effect, on the contrary, if it exceeds the above range, there is a problem that the acrylate-based copolymers are entangled with each other at high temperature and difficult to apply to the cosmetic composition. In addition, when the content of the polyhydric alcohol is less than the above range, it is difficult to liquefy the acrylate-based copolymer, so that it is difficult to prepare an aqueous solution. When the content of the polyhydric alcohol exceeds the above-mentioned range, the film strength of the acrylate-based copolymer is softened, so that the durability is lowered. . When the content of the polyethylene glycol fatty acid ester is less than the above range, the effect of addition to the solubilizer is insignificant, and thus it is difficult to obtain a stable aqueous solution at high temperature. On the contrary, when the content exceeds the above range, the stability of the aqueous solution is rather deteriorated.

The acrylate-based copolymer included in the aqueous solution of the acrylate-based copolymer may be used without limitation as long as it can form a coating when the cosmetic composition is dried, thereby providing curling power and persistence to the eyelashes. Typically, acrylate / methacrylate copolymers, acrylate / dimethicone copolymers, acrylate / acrylamide copolymers, acrylate / dimethicone methacrylate copolymers, acrylate / ethylhexyl acrylate copolymers, and One selected from the group consisting of acrylate / vinylpyrrolidone copolymers is possible.

Preferably, an acrylate copolymer having a glossiness of 60 °, 86%, an elastic modulus of 12.7 MPa, a tensile strength of 19.4 MPa, an elongation of 220%, and a hardness of 23 (Sward rocker hardness) is used. .

The cosmetic composition of the present invention is a water-in-oil emulsion, and an emulsifying method is well known to those skilled in the art. For example, the emulsion may be prepared using an ultrasonic wave crusher, a homomixer, a stirrer, or the like.

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