Make-up cosmetic composition of oil-dispersed cake type with high elasticity and the method of preparing Julia}

1 shows the form in which a liquid is present between particles.

The present invention relates to a highly elastic oil-dispersed cake formulation makeup cosmetic composition excellent in the sense of touch and a preparation method thereof.

Generally, a dispersive makeup cosmetic is divided into oil dispersion and water dispersion. Generally, the oil dispersing type has the advantages of excellent durability and high covering power, but it has a disadvantage of feeling heavy and bundling. On the other hand, the water dispersion type has a disadvantage in that its usability is light and neat, but its sustainability and coverage are low.

The oil-dispersion formulation to be dealt with in the present invention is made of the composition of the particles and the liquid (oil) constituting the aggregates and the liquid intercalates in various forms between the particles constituting the aggregates to affect the binding and binding force between the particles. . In this case, depending on the form in which the liquid exists between the particles, it can be classified into a pendulum state, a funicular state, a capillary state, and a suspended state.

When the amount of the liquid used in the formulation is 0.1 to 5.0% by weight, a concave lens-like liquid-phase bond is formed between the particles. This state is the pendulum state (Fig. 1, Fig. 1), where the coupling of the aggregate is localized to the contact points of the particles, and the particle classification corresponds to this. Powdered powder has flowability in powder state, is not molded, and has the advantage of being able to express bright skin and bright skin when used.

As the liquid content in these agglomerates increases (5 to 30 wt.%), The liquid forms a continuous phase, but air is dispersed in some spaces and begins to coalesce with the adjacent liquids. ). This applies to formulations such as compacts, twin cakes and powder factories, which have the property of being molded when a certain pressure is applied. The pendulum state and the funicular state are strictly powder dispersion techniques.

When the pores of the agglomerate are all filled with liquid (30 to 50% by weight), it becomes a capillary state (Fig. Capillary cake formulations have excellent coverage and durability, but they are heavy and have a thick makeup, which is a burden on the skin.

If the liquid content is further increased (50 to 80% by weight) and the liquid is completely enclosed while isolating the particles (Fig. 1 in Fig. 1), the aggregates cannot maintain the molded form and are suspended or suspended. ) And lipsticks and dispersed liquid foundations.

The makeup cosmetic composition research for the pendulum state, cable state, suspension state, and the like has been steadily progressed, while the disperse cake formulation having high elasticity in the capillary state. There was very little research on.

In order to improve the disadvantages of the capillary formulation described above, and to stabilize the capillary high-elastic dispersion cake formulation having excellent touch feeling, the present inventors conducted a study on not only a makeup cosmetic composition but also a preparation method thereof. As a result, by using silicone elastomer components, it is possible to form a sponge-like network structure to provide a unique formulation having high elasticity, and the formulation provides differentiated excellent effects such as excellent touch feeling, smooth skin texture effect, and wrinkle concealment effect. It was confirmed that this can be done, and this invention was completed.

Accordingly, it is an object of the present invention to provide a makeup cosmetic composition and a method for producing the same, which has a high elasticity and a good touch, and smoothes wrinkles and skin textures.

In order to achieve the above object, the present invention is a hybrid silicone elastomer powder; Silicone elastomer gels; And it provides a high elastic oil dispersion formulation makeup cosmetic composition comprising a silicone elastomer component consisting of a component of the silicone elastomer gel and wax blended.

In addition, the cosmetic composition is characterized in that the silicone elastomer further contains a liquid oil component and wax of the oil phase component.

In addition, the present invention comprises the steps of mixing, pulverizing the hybrid silicone elastomer powder using a Henschel mixer; And injecting the disintegrated hybrid silicone elastomer powder into an oil phase, and then preparing the capillary state using an azi mixer. It provides a method for producing a highly elastic oil dispersion formulation makeup cosmetic composition, characterized in that consisting of.

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

Makeup cosmetic composition of the present invention consists of an oil phase component, a pigment component and a silicone elastomer component.

Pigment components and oily components are generally used in makeup cosmetics, pigment components are titanium dioxide, talc, silica. Polymethyl methacrylate, nylon powder, iron oxide and the like, and the oil phase component contains oil, wax, silicone oil, pigment dispersant and the like.

The silicone elastomer component used in the present invention is composed of a hybrid silicone elastomer powder, a silicone elastomer gel component, and a component blended with a silicone elastomer gel and a wax. Specifically, the hybrid silicone elastomer powder component may be dimethicone / divinymethicone / silsesquioxane crosspolymer, polymethylsilsesquioxane, polysilicon-11 / laures-12, dimethicone / divinyldimethicone / The silicone elastomer gel component is cyclopentasiloxane / polysilicone-11 / dimethicone, dimethicone / vinyldimethicone crosspolymer, vinyldimethicone / lauryl dimethicone crosspolymer / squalane, etc. The silicone elastomer gel and wax blended component is composed of cyclopentasiloxane / polysiloxane-11 / beeswax. Wax is composed of beeswax, ozokerite, carnauba wax and the like.

The total pigment content, including the silicone elastomer component (hybrid silicone elastomer powder, silicone elastomer gel and silicone elastomer gel and wax blended components) is 50 to 70% by weight based on the total weight of the composition, the content of the silicone elastomer component in the pigment content It is characterized in that 80 to 85.7% (40 to 60% by weight relative to the total weight of the cosmetic composition).

When the silicone elastomer phase is used in less than 40% by weight relative to the total weight of the cosmetic composition, the smooth skin texture correction and wrinkle concealment effect is good, but the effect on the touch and elasticity to be achieved in the present invention is insufficient. As with the total content of the pigment, when the silicone elastomers are used in excess of 60% of the total weight of the composition, the adsorption and absorption of the oil phase components are excessive due to the excellent oil absorption of the silicone elastomer, which inhibits the flowability during filling. As a cause, it is difficult to formulate the cake type to be studied in the present invention, and even if the formulation is made, it may cause a problem of tearing and barring when taking the contents.

In addition, when the total content of the pigment including the silicone elastomer is used in less than 50% of the total weight of the cosmetic composition, the liquid completely encloses the particles, and the agglomerates cannot maintain the molded form or have elasticity. If the content exceeds 70% by weight of the total composition, the oily components are excessively adsorbed, and the formulation becomes a cable (Funicular) state.

In addition, waxes of the oil phase component is characterized in that the 2.0 to 4.0% by weight is used, it should be designed to be evenly dispersed on the pigment and the surface of the silicone elastomer particles. This imparts flowability at high temperatures of more than 70 ° C. upon filling, and plays an important role in forming network structures by crystallization at the particle surface of pigments and silicone elastomers. This does not cause lumps or smears when the contents are taken and does not easily disintegrate, and stabilizes the sponge-like structure, thereby maintaining a high elastic cake formulation. If the amount of wax is used in excess of 4.0% by weight, the formulation has a high hardness, and the touch and elasticity are rather inferior. If the amount is less than 2.0% by weight, the flow and crystallinity are weak so that the cake formulation of the network structure cannot be formed. .

In addition, the liquid oil component is characterized in that it contains 30 to 50% by weight relative to the total weight of the cosmetic composition. When the liquid oil component is used at less than 30% by weight of the total weight of the cosmetic composition, the liquid oil component is in a pendulum state in which the binding of the aggregate is limited to the point of contact of the particles. The liquid forms a continuous phase, but in some spaces the air dissipates and changes to a true cable state that begins to coalesce into adjacent liquids.

The formulations studied in the present invention showed a significant difference in touch and elasticity according to manufacturing facilities and manufacturing processes.

In particular, since the hybrid silicone elastomer powder used as a characteristic raw material in the present invention is a raw material having an easily aggregated property, it is not dispersed completely when dispersed in a liquid phase without disintegration, and is not uniformly dispersed in the formulation. When present and taking the contents, cake cakes easily collapsed by lumping or by small force.

In order to remedy these shortcomings, the inventors conducted a study according to dispersion time and speed, and found that when mixed and pulverized for 1 to 2 minutes using a Hensle mixer at a speed of 500 to 1000 rpm, it was sufficiently disintegrated. . At speeds below 500 rpm, undissolved raw materials are present, and at high speeds above 1000 rpm, silicon elastomers are more strongly agglomerated by electrostatic forces.

And the process for uniformly dispersing the pigment and the disintegrated hybrid silicone elastomer component in the oil phase (oil). First, the pigment and the hybrid silicone elastomer powders were introduced into the oil phase, and the azi mixer was prepared at a low speed (200 to 500 rpm) to be sufficiently dispersed for 10 minutes or more to prepare the oil in a capillary state. At this time, when the azimixer's speed is less than 200rpm, the dispersion efficiency is decreased, and when the azimixer's speed is higher than 500rpm, the dispersion state is changed into a kneaded or suspended state formulation, so that the inventors cannot form a sponge-like network structure to be studied. The elasticity was remarkable and the fall was observed.

The makeup cosmetic composition according to the present invention is limited to a cake formulation oil-dispersed makeup cosmetic composition having excellent elasticity and forming a sponge-like network structure, but in its function, cosmetics such as makeup base, foundation, concealer, skin cover, etc. It may be formulated in a form.

The high elasticity of the makeup cosmetic composition according to the present invention means that it has a characteristic of being restored to its original state within 0.01 to 1 second under pressure.

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

[ Test Example  1] Effect on Elasticity Verification test

SUN RHEOMETER CR-500DX (SUN SCIENTIFIC Co., Ltd.) was used as a measuring device for verifying the effect on the elasticity of the highly elastic oil-dispersed cake formulations prepared in Examples and Comparative Examples, and restored when pressed to a constant depth of 5 mm. The method of measuring elasticity was devised by measuring the ratio of depth and the force (hardness) required for deformation of 5 mm. The measurement results are shown in Table 2.

Example 1 Example 2 Example 3 Comparative Example 1 Comparative Example 2 Comparative Example 3 Elasticity 72% 81% 86% 26% 8% 42% Hardness 28 24 18 58 78 43

(Measured by the ratio of elasticity restored when pressed to a depth of elasticity = 5 mm

  Force required for deformation of hardness = 5 mm.)

In the results of Table 2, in the case of Example 1, Example 2 and Example 3, which is a dispersion-dispersed cake formulation prepared according to the present invention, the elasticity compared to Comparative Example 1, Comparative Example 2 and Comparative Example 3 It can be seen that the excellent and the hardness is low.

[ Test Example  2] Touch , Cushion  And smooth On skin texture  Usability evaluation result for

Response to touch, cushioning, and smooth skin texture after using Examples 1, 2, 3 and Comparative Examples 1, 2, and 3 for 50 women aged 40 to 40 who make up makeup for 3 days or more a week The subjective evaluation was conducted through a survey. The survey was to display the satisfaction of the effect of the product for each item divided by 1-5 points (the higher the number the higher the satisfaction), the results are shown in Table 3 below.

Example 1 Example 2 Example 3 Comparative Example 1 Comparative Example 2 Comparative Example 3 Touch 4.2 4.5 5.0 2.1 1.5 2.5 Cushion 4.3 4.6 5.0 1.8 1.0 2.3 smooth
Skin expression 4.2 4.5 4.7 2.8 2.1 3.4

In the above results, in the case of Example 1, Example 2, and Example 3, the evaluation results on touch feeling, cushioning feeling, and smooth skin expression showed excellent satisfaction of 4 points or more, whereas Comparative Example 2 was applied to touch feeling and cushioning feeling. Satisfaction level was particularly low, and Comparative Example 1 and Comparative Example 3 showed a low level of satisfaction with the cushion feeling, but relatively good evaluation of the items of smooth skin expression.

It can be seen that Comparative Example 1, which does not use wax, is not stabilized by the cake formulation, and Comparative Example 3, which does not have a dispersion process of silicone elastomer, may be inferior in evaluation of elasticity and touch feeling.
