Description

Powder cosmetic composition and a method for producing the same {Composition for cosmetic powder and a fabricating method of the same}

The present invention relates to a powder cosmetic composition and a method for producing the same, and to a powder cosmetic composition excellent in molding stability and usability and a method for producing the same.

Generally, the powder cosmetic composition is divided into compact powder and powder powder. In the case of a compact powder, an aluminum dish or a plastic dish is required to stabilize the contents of the powder composition. Therefore, the compatibility relationship between the contents and the dish is greatly changed depending on the height (T) and the diameter (D) of the dish. For example, in the case of a compressed powder containing talc (talc) of 40% by weight or more, a powder composition that provides an optimum cosmetic effect even with a small amount (6.0% by weight or less) of a binder regardless of the height and diameter of the dish However, if a plate-like powder component such as mica (mica) is formulated in the same amount as above, when the size of the plate is widened, it may not be properly secured in forming stability and cracking may occur due to a weak impact.

In addition, in the case of pearl (titanium dioxide coated mica) under the same mixing conditions, the same labile formulation as mica is formed. Therefore, there is a disadvantage in that the compacted powder cannot be molded on a plate type plate without a general girder. And, there is a formulation formed by kneading a water-soluble gel aqueous solution with another compound powder like a similar domed powder eye shadow cosmetic composition (Patent Application No. 10-2009-0059109), but applying a single component as described above to make a domed cosmetic composition The method is difficult to adjust the optimal blending amount according to the type of gel, the make-up effect does not come down when makeup is made, and the cosmetic applicator such as puff is rubbed on the surface of the formulation excessively. As the friction heat is generated on the surface of the formulation, the water-soluble gel generates thermal polymerization, which causes caking on the surface of the product, resulting in deterioration of quality, and when the cosmetic composition is dried at a specific temperature for a predetermined time. The gelling agent film is formed on the surface while the water-soluble gelling agent solution moves to the cosmetic surface with water and evaporates, The surface hardening is produced by.

In addition, there is a difference in volume expansion between the water-soluble gelling agent and the powder causes unstable surface cracks. Therefore, it does not have a proper payoff as a product, has the disadvantage that the drop stability is unstable and the makeup effect is considerably inferior.

Advantages and features of the present invention and methods of achieving them will become apparent with reference to the embodiments described hereinafter. The present invention may, however, be embodied in many different forms and should not be construed as being limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. Is provided to fully convey the scope of the invention to those skilled in the art, and the invention is only defined by the scope of the claims.

Unless otherwise defined, all terms (including technical and scientific terms) used in the present specification may be used in a sense that can be commonly understood by those skilled in the art. Also, commonly used predefined terms are not ideally or excessively interpreted unless explicitly defined otherwise.

Hereinafter, a powder cosmetic composition and a manufacturing method thereof according to embodiments of the present invention will be described.

Powder cosmetic composition according to an embodiment of the present invention may include a S / W (silicone in water) aqueous solution and a powder mixture.

Here, the content of the aqueous solution of silicone in water (S / W) may be 20 to 50% by weight based on the total composition of the powder cosmetic composition. When the content of S / W (silicone in water) emulsion solution is less than 20% by weight, it may be difficult to secure the makeup effect and drop stability of the powder cosmetic composition.

On the other hand, when the content of the aqueous S / W (silicone in water) emulsion solution exceeds 50% by weight, the content of the powder complex may be reduced, so it may be difficult to exhibit the specific function of powder cosmetics.

On the other hand, the content of the powder mixture may be 50 to 80% by weight relative to the total composition of the powder cosmetic composition. If the content of the powder mixture is less than 50% by weight, since the content of the powder composite agent is reduced, it may be difficult to exhibit the specific function of the powder cosmetics. On the other hand, when the content of the powder composite agent exceeds 80% by weight, the aqueous solution of S / W (silicone in water) may not be sufficiently added, it may be difficult to ensure the makeup effect and drop stability of the powder cosmetic composition.

First, S / W (silicone in water) aqueous solution may include water, water-soluble complex gelling agent, silicone oil, surfactant.

The water-soluble complex gelling agent can prevent the powdery blowing phenomenon contained in the powder mixture. In addition, the water-soluble complex gelling agent can cure the powder cosmetic composition, it is possible to improve the drop stability of the powder cosmetic composition. In addition, the water-soluble complex gelling agent can improve the application of the powder cosmetic composition to the human skin, moisture and adhesion.

The water-soluble complex gelling agent may be included in an amount of 0.01 to 5.0% by weight in an aqueous solution of silicone in water (S / W). When the content of the water-soluble complex gelling agent is less than 0.01% by weight, the effect of adding the water-soluble complex gelling agent is hardly expressed. When the content of the water-soluble complex gelling agent exceeds 5.0% by weight, powder blowing may be prevented, but a caking phenomenon may occur on the surface of the product, thereby degrading the quality. In addition, a cured film may be formed on the surface of the product, and the inconvenience of having to remove the cured film separately may occur.

Such water-soluble complex gelling agents are, for example, ammonium acryloyl dimethyl taurate / V icopolymer (AMMONIUM ACRYLOYLDIMETHYLTAURA TE / VP COPOLYMER), polyvinyl alcohol, polyvinylpyrrolidone, xanthan gum, magnesium aluminum silicate (MAGNESIUM ALUMINUM SILICATE), hydroxyethyl cellulose (HYDROXYETHYLCELLULOSE), cellulose gum (CELLULOSE GUM) and sodium polyacrylate (SODIUM POLYACRYLATE) at least two selected from the group consisting of.

Silicone oil may be included in an aqueous solution of silicone in water (S / W) emulsion. Silicone oil may maintain the stability of the matrix upon evaporation of water contained in the aqueous solution of silicone in water (S / W). In addition, the permeability and lubricity of S / W (silicone in water) aqueous solution may be improved. To this end, the silicone oil may have a property of relatively low viscosity. For example, the silicone oil may have a viscosity of 0.65 to 2.0 g / cm * s. If the viscosity of the silicone oil is less than 0.65 g / cm * s, the effect of the addition of the silicone oil is insignificant, it may be difficult to maintain the stability of the matrix when evaporating water. On the other hand, when the viscosity of the silicone oil exceeds 2.0 g / cm * s, the volatility of the silicone oil can be lowered, the permeability to water may also be lowered. As a result, the overall surface properties of the powder cosmetic composition may be lowered.

On the other hand, the silicone oil may contain 0.01 to 10.0% by weight in the aqueous solution of silicone in water (S / W). When the content of the silicone oil is less than 0.01% by weight, the effect of adding the water-soluble complex gelling agent is hardly expressed. When the content of the silicone oil exceeds 10.0% by weight, it is possible to secure the effect of maintaining the stability of the matrix upon evaporation of the water contained in the aqueous solution of silicone in water (S / W) emulsion, but in relation to other formulations The content may be vaporized more than necessary. As a result, overall physical properties of the powder cosmetic composition may be deteriorated.

The surfactant may function to uniformly disperse the water-soluble complex gelling agent and silicone oil dissolved in an aqueous solution of silicone in water (S / W) emulsion as water. The content of the surfactant may be 0.1 to 1.0% by weight. If the content of the surfactant is less than 0.1% by weight, the effect of adding the surfactant is insignificant, so that the water-soluble complex gelling agent and the silicone oil may not be uniformly dispersed in water as a solvent. When the content of the surfactant exceeds 1.0% by weight, the water-soluble complex gelling agent and the silicone oil may be uniformly dispersed in water as a solvent, but may be vaporized more than necessary in relation to other formulations. As a result, overall physical properties of the powder cosmetic composition may be deteriorated.

On the other hand, S / W (silicone in water) aqueous solution may include a residual amount of water as a solvent.

The powder mixture may include a powder phase and a binder phase.

Here, the powder phase may be formed by, for example, mixing and dispersing a white pigment, an extender pigment, an anti-caking agent, a dye, a binder, and a preservative.

The extender pigment may include talc, mica, silica, nylon powder, bismuth oxychloride and the like.

Anticaking agents may include nylon powder, silica, magnesium stearate, and the like.

The pigment may include one or more selected from iron oxide, ultramarine blue, blue, titanium dioxide, tar-based pigments, pigmented lakes of natural pigments, manganese violet, chromium oxide, chromium hydroxide, and pearlescent pigments.

The binder may include one or more selected from silicone oils, hydrocarbon oils, higher fatty acid oils, lanolin oils, animal oils, and vegetable oils.

The binder phase may be, for example, an aqueous binder, and may bind the particles constituting the powder to each other. When the binder is an aqueous binder, the binder may be formed by mixing and dispersing a water-soluble thickener, a polyol, DI water, and a preservative. The water soluble thickener may include magnesium aluminum silicate. Magnesium aluminum silicate serves as a thickener, the plate-like structure can be swelled by moisture or the like to increase the viscosity.

Next, the manufacturing method of a powder cosmetic composition is demonstrated.

According to another embodiment of the present invention, a method for preparing a powder cosmetic composition includes 0.01 to 5.0% by weight of a water-soluble complex gelling agent, 0.01 to 10.0% by weight of silicone oil, 0.1 to 1.0% by weight of a surfactant, and a residual amount of Mixing water to form a S / W (silicone in water) emulsion aqueous solution, forming a powder mixture, and mixing the S / W (silicone in water) emulsion aqueous solution and powder mixture have.

Forming an aqueous solution of silicone in water (S / W) may be performed as follows.

First, water is prepared as a solvent, and the water is stirred at a low speed (eg 600 rpm) by using an agitator, for example, an azi mixer.

Subsequently, a surfactant and a water-soluble complex gelling agent were added and dissolved in the water under stirring.

Subsequently, silicone oil is added and stirred at a high speed (for example, 4000 rpm) to form an aqueous solution of silicone in water (S / W). Forming the aqueous solution of silicon in water (S / W) may be performed in an atmosphere of 30 to 40 ℃. When the step of forming the aqueous solution of silicone in water (S / W) emulsion is performed in an atmosphere of less than 30 ℃, mixing of the water-soluble complex gelling agent and the silicone oil may not occur well. If the step of forming the aqueous solution of silicone in water (S / W) emulsion is performed in an atmosphere exceeding 40 ° C., a part of the surfactant, the water-soluble complex gelling agent or the silicone oil may thermally decompose, silicone in water) There is a risk that the physical properties of the emulsion aqueous solution is lowered.

Next, a powder mixture is formed.

First, the powder phase of the powder mixture is formed by dispersing white pigment, extender pigment, anti-caking agent, pigment, binder, and preservative at high speed for a predetermined time.

Subsequently, the water-soluble thickener, polyol, DI-water, and preservative are mixed and dispersed to form a binder phase.

Subsequently, the powder phase and the binder phase are mixed to form a powder mixture agent.

Next, a powder cosmetic composition is formed by mixing a S / W (silicone in water) aqueous solution and the powder mixture. At this time. The content of the aqueous solution of silicone in water (S / W) emulsion is 20 to 50% by weight, and the content of the powder mixture is 50 to 80% by weight.

Meanwhile, after mixing the S / W (silicone in water) aqueous solution and the powder mixture, the mixture may be dried at 20 ℃ to 70 ℃ for 5 to 12 hours.

Here, when the drying temperature is less than 20 ° C, drying may not occur smoothly. When the drying temperature exceeds 70 ° C, a part of the surfactant, the water-soluble complex gelling agent or the silicone oil may be thermally decomposed in the mixed liquid. In addition, drying may occur relatively rapidly, such that a powdered cosmetic composition whose surface is cured may be formed. On the other hand, if the drying time is less than 5 hours, sufficient drying may not occur, and if the drying time exceeds 12 hours, sufficient drying is achieved, and thus no further drying process is necessary.

Hereinafter, the present invention will be described in detail with reference to examples. However, the following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.

[ Comparative example  1 to 4]

Based on the composition of Table 1, powder cosmetic compositions were prepared in substantially the same manner as in Examples 1 and 2.

[ Experimental Example ]

The powder cosmetic composition prepared in Examples 1 and 2 and Comparative Examples 1 to 4 were used for one month by 30 expert panelists, and then physical property evaluation was performed, and the results are shown in Table 2 below. At this time, the higher the score on the basis of 5 points is the better quality.

※ Evaluation Criteria (Very Good: 5, Excellent: 4, Normal: 3, Short: 2, Very Low: 1)

As can be seen from the above results, according to Examples 1 and 2 of the present invention, the application property, moisturizing feeling, adhesion, malleability and drop stability were all superior to Comparative Examples 1 to 4. On the other hand, in the case of Comparative Examples 1 to 4, it was found that the overall superiority of the quality compared to Examples 1 and 4.

That is, when using a plurality of water-soluble complex gelling agents, that is, when using a plurality of water-soluble complex gelling agents, a powder cosmetic composition of better quality could be produced.

In particular, as in Comparative Example 2, when only 3.0% by weight of MAGNESIUM ALUMINUM SILICATE is blended with a water-soluble complex gelling agent, the powder and powder are stably bonded to each other in the process of evaporation of water and silicone oil from the inside of the powder phase to the outside.
