Description

A mascara composition with Hollow Powder

The present invention relates to an oil-in-water mascara composition comprising dextrin fatty acid ester as a liquid crystal base, a hollow resin powder, and an oil thickener prepared from surfactants, oils and polyols.

The function of the general mascara is to express the eyes more vividly and vividly by applying the mascara and eyeliner make-up for the women who want to be beautiful and the eyelashes are relatively short and fragile and the eyes are small. In particular, since the eyelashes of Asian women are shorter and weaker than those of Western women, there is a great desire to obtain the effects of volume, curling, long lash, etc. using mascara.

Such mascara is divided into an emulsion type and a dispersion formulation according to the formulation, and an emulsion type mascara has a water-in-oil type and an oil-in-water type, and a dispersant type has an oil dispersion type in which powder and film former are dispersed in a solvent. Among them, oil-based mascara is mainly developed because of stability and ease of use.

Water-in-oil type mascara has an advantage of applying water evenly to the inside of the water because it has a strong water resistance and moisture retention, but it is difficult to cleanse in water and oily. .

However, the oil-in-water mascara, which has a traumatic water, can provide excellent persistence, easy cleansing, and a light feeling.However, when the mascara is used for a long time, the water in the trauma dries and the mascara liquid hardens and spreads evenly. There were disadvantages that appeared.

Accordingly, even when the oil-in-water mascara and the oil-in-water type mascara have a long service life, the moisturizing power is maintained and the coating property needs to be improved evenly.

In mascara, volume means that the eyelashes are thicker than the original state and are thinned and richly produced. Many methods have been developed to give the volume. In order to enhance this effect, it was expected to use a large amount of a wax or film-forming polymer in an oil phase or to use a powder to have an effect such as volume.

However, when a large amount of spherical powder is used, powdering and deterioration are observed, and when a large amount of polymer or wax is used, the volume is excellent, but the eyebrows are stuffy due to the weight applied to the eyebrows and the curling is difficult to maintain, resulting in poor curling retention.

Specifically, mascara compositions containing a silicone resin powder such as polymethylsilsesukioki acid and having excellent volume feeling made by a phase inversion emulsifision are disclosed in Japanese Patent Application Laid-Open No. 11-12132.

However, this mascara composition can provide simply a good sense of volume, but there was a drawback of severe powdering and agglomeration phenomenon. Conventionally, if people who use mascara are satisfied with one function, they have recently developed a technology capable of satisfying multifunction because they prefer multifunction, that is, a mascara that simultaneously imparts volume, curling, curling, and the like.

There are various types and forms of powder using conventional patents and techniques for mascara compositions, and frequently used powders include spherical silicone resin powders and inorganic powders. As a specific example, a mascara composition (Japanese Patent Application No. 2004-315420) prepared by mixing a hydrocarbon-based fraction with a non-aqueous polymer dispersion in which a polymer is dispersed in volatile silicone and a hollow powder is disclosed. However, the mascara composition has a disadvantage in that it is difficult to apply over time and bleeding caused by the oil used to improve the application ability, but the volume and curling retention strength by using a hollow powder.

On the other hand, liquid crystals have excellent water retention capability and improve the emulsification stability because they form a rigid liquid crystal film of an interfacial film between oil and water in an emulsified product. Therefore, there are many examples of using a liquid crystal base in cosmetics for improving water resistance and maintaining moisturizing power (Korean Patent Publication Nos. 95-28761, 2002-0095609, 2002-0095610, and 1999-025563). There was no example used for.

Accordingly, the present inventors have studied a method for improving the applicability and eliminating the problem of dropping the coating power over time in mascara containing a hollow resin powder, without using oil. Dextrin fatty acid ester acts as an oil thickener And a liquid crystal base, it has been found that the above problems can be solved. The liquid crystal base is prepared according to the manufacturing method of Korean Patent Application No. 2003-0091925 filed by the present inventors. The present invention finds that the applicability and coating power do not drop over time by including the liquid crystal base in the mascara composition. To complete.

Accordingly, an object of the present invention is to improve the emulsification stability and spreadability by using an oil thickener without using oil to improve the coating force and excellent volume and curling holding power by using hollow resin powder. The present invention provides a mascara composition which is free from moisture and maintains moisturizing and coating power continuously using a liquid crystal base.

In order to achieve the above object, the mascara composition of the present invention is characterized by containing a dextrin fatty acid ester as a liquid crystal base, a hollow resin powder, and an oil thickener prepared from a surfactant, an oil and a polyol.

Hereinafter, the present invention will be described in more detail.

The present invention further contains a dextrin fatty acid ester in the composition containing the hollow resin powder to stabilize dispersion so that the powder does not agglomerate with each other, so that it can be applied smoothly, does not cause powdering or agglomeration phenomenon, and contains a liquid crystal base to moisturize And an excellent oil-in-water mascara composition that maintains applicability continuously.

The hollow resin powder includes acrylic acid, acrylic acid ester, methacrylic acid, methacrylic acid ester, acrylonitrile, and the like, but it is preferable to use methacrylic acid ester. The shape of the powder is particularly limited to the hollow form, but the powder shape is appropriately selected from powders having an elliptical shape, a plate shape, a spherical shape, and the like. Hollow resin powder is generally commercially available, for example, Matsumoto microphone loss fair MLF series (MLF-50ST, MLF-50SCA, MLF-100SCA, MLF-100CA, MLF-30STI) ), MO-bead manufactured by Miyoi Kasei Co., Ltd. and Gantzpal GMH-0850 manufactured by Kantsu Chemical Co., Ltd. are manufactured and marketed in various sizes and specific gravity, and commercially available hollow resin powder is used in the present invention. 0.1 to 10% by weight. When using a small amount of less than 0.1% by weight can not see the effect of volume and curling holding function, such as 10% by weight due to the increase in hardness due to the increase in hardness when the content is stiffly applied powder falls.

The mascara composition of the present invention further contains dextrin fatty acid ester in addition to the above hollow resin powder in order to simultaneously provide a sense of volume and spreadability.

Dextrin fatty acid ester is an oil thickening agent that increases the pigment and hollow resin powder by combining with hydrogen group (-OH) and hydrogen (-H) of dextrin palmitate on the surface of pigment dispersed in oil phase. It helps to be uniform and helps to stabilize the emulsion. It is also very useful as a powder and pigment dispersant in oil phase due to its good compatibility with wax.

Dextrin fatty acid ester used in the present invention is represented by the following formula (1), and specific compounds include dextrin palmitate, dextrin palmitate / ethyl hexanoate, dextrin stearate, dextrin behenate, dextrin myristate, and the like. Each can be used individually or in mixture. In particular, it is more preferable to use dextrin palmitate / ethyl hexanoate, which is a derivative of dextrin palmitate, because the fatty acid ester length is appropriate and ethyl hexanoate is substituted for hydrogen, so the oil thickening effect is excellent.

[Formula 1]

(In the above, A is independently hydrogen or R-CO- (acyl group), R is a C ₇ -C ₂₁ linear or branched alkyl or alkenyl group, n is an integer of 3 to 200. Are all hydrogen.)

The mascara composition of the present invention contains the above dextrin fatty acid ester in an amount of 1 to 15% by weight based on the total weight of the composition. It is too small when used in less than 1% by weight can not describe the effect of improving the viscosity and dispersion of powder, when used in excess of 15% by weight is too high rise in viscosity rather deteriorating applicability and eyelashes This is because it is difficult to maintain a creamy viscosity suitable for application.

On the other hand, the present inventors in the oil-in-water type mascara and water-dispersible eye make-up of the external wound water, the mascara liquid of the brush is dried when a long period of use is not uniformly applied to the phenomenon that the hollow resin powder If it contains the disadvantage of the composition is stiff due to the wax and oil-based oil absorption of the powder and to solve the advantage when the oil is added to the composition, another disadvantage caused by the oil is a bleeding phenomenon occurs. Thus, a study was made on a method for solving the above problems, and as a result, when the liquid crystal base is further contained, the present invention finds that the above problems can be solved by excellent water content, moisturizing retention and emulsification stability. Was done. The above invention has been invented by a conventional inventor (Korean Patent Application No. 2003-0091925), when the liquid crystal base is used in a mascara composition, especially in an oil-in-water type mascara, the liquid crystal base is soft because it has excellent moisture function and moisturizing retention. It was found to give applicability.

Accordingly, the oil-in-water mascara according to the present invention is stabilized by a liquid crystal base having excellent water-moisture and moisture-retaining ability, so that the stiffness of application due to the hollow resin powder, that is, the coating property is improved, and the coating is applied even after a long period of use. Immediately after preparation is to provide a mascara composition as the composition state.

The liquid crystal base contained in the mascara composition of the present invention is prepared by the same method as described in Korean Patent Application No. 2003-0091925, wherein the liquid crystal base contains a surfactant, an oil, and a polyol, and the content of the mascara composition is It is 1 to 20% by weight, depending on the formulation, but preferably 3 to 10% by weight When used in a small amount of less than 1% by weight can not feel the effect of improvement in application properties due to the liquid crystal base, 20% by weight After the mascara solution is applied to the eyebrows, the drying speed is slowed down and the effect is to bury under the eyes.

The liquid crystal base is prepared to contain 1 to 30% by weight of surfactant, 1 to 20% by weight of oil, and 1 to 20% by weight of polyol based on the total weight of the base.

The surfactant may be used at least one selected from fatty acids and polyglyceryls, and specific examples thereof include glyceryl monostearate, arachidyl alcohol behenyl alcohol-arachidyl glucoside (Montanov 202), and polyglyceryl-3- Methylglucose distearate (TEGOCARE 450). If the amount of the surfactant is less than 1% by weight, no liquid crystal is formed, and if it exceeds 30% by weight, mascara is gelled, which is not preferable.

The oil used in the present invention is not particularly limited, but for example, one or more selected from the group consisting of triglycerides, aliphatic alcohols, liquid paraffins and squalanes based on hydrocarbons are used. If the amount of oil is less than 1% by weight or too small or more than 20% by weight, the liquid crystal is not well formed, rather it may inhibit liquid crystal formation, so it is preferable to use 1 to 20% by weight.

In addition, the polyol used in the present invention is glycerin, butylene glycol, propylene glycol, polyethylene glycol and the like, the most commonly used glycerin is used. The polyol is used in an amount of 1 to 20% by weight based on the total weight of the base. When the amount of the polyol is large, the liquid crystal is well formed, but when the polyol is more than 20% by weight, the eyelid phenomenon occurs and the persistence is weak. It is preferable to use it in an amount of 20% by weight or less, because disadvantages occur.

Hereinafter, the present invention will be described in detail with reference to Examples and Experimental Examples, but the present invention is not limited only to these examples.
