Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a make-up cosmetic composition,

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 is made of the composition of particles and liquid (oil) constituting the agglomerate, and the liquid is interspersed in various forms between the particles constituting the agglomerate, which affects the bonding and bonding force between 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. The powder classification has flowability as a powder state, and is not molded, and it has the advantage of being able to exhibit a disadvantage in that powdery flakes are severely used and bright skin expression.

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.

When the liquid content further increases (50 to 80% by weight) and the liquid completely surrounds the particles while isolating the particles (Fig. 1, d), the aggregate can not maintain the molded form, Lipstick, and dispersed liquid foundation.

Among them, the conventional floating state is advantageous in that the pigment is dispersed in the oil and stabilized with wax to form a formulation, thereby speeding up the composition adherence to the skin. However, there is a problem in that spreadability and spreadability are poor when the composition is initially applied.

Domestic Patent No. 0805218

Accordingly, the present inventors have made a study to provide a cosmetic composition capable of shortening the make-up speed because of its excellent spreadability and spreadability and fast adhesion speed. As a result, unlike the conventional wax-stabilized oil dispersion form, ABn type silicone block copolymer and dry It is possible to realize a liquid phase formulation in which the dispersibility of the pigment is improved by using silica as a dispersant, and the present invention has been completed.

Accordingly, it is an object of the present invention to provide a makeup cosmetic composition which can be easily applied to skin and is excellent in adhesion.

The dispersion stability and feeling of use of the makeup cosmetic compositions prepared in Examples 1 to 5 and Comparative Examples 1 to 7 were evaluated by the following methods.

[Test Example 1] Comparison of dispersion stability

To confirm the dispersion stability of the makeup cosmetic composition of the present invention, 30 g of each of Examples 1 to 5 and Comparative Examples 1 to 5 were taken and allowed to stand at room temperature for one week, and the degree of dispersibility was confirmed. And Figs. 2 to 3.

Test substance Stability of pigment dispersion Redistribution after coagulation Example 1 ○ ○ Example 2 ○ ○ Example 3 ○ ○ Example 4 ○ ○ Example 5 ○ ○ Comparative Example 1 ○ X Comparative Example 2 X ○ Comparative Example 3 △ ○ Comparative Example 4 ○ △ Comparative Example 5 ○ X <Stability Evaluation Standard>
X: very poor (dye separation visible / not redispersible)
△: slightly poor (visible within 1 week of pigmentation / slight reddening of redispersions)
○: Good (no separation of pigment for more than one month / cleanly mixed in redispersing)

From the results of Table 4, it was confirmed that the makeup cosmetic compositions of Examples 1 to 5 containing the dispersing agent of the present invention had excellent dispersion stability as compared with Comparative Examples 1 to 5 using other dispersing agents. In addition, when Examples 1 to 5 are compared, it can be seen that the stability is good regardless of the type of the ABn-type silicone block copolymer and the dry silica.

This is because the ABn-type silicone block copolymer used in the present invention is located at a certain distance from the powder surface, and the silicon portion is bulky, as compared with the branched silicon polymer, It can stabilize one by one. Also, in the case of dry silica, it has a low specific gravity and a large specific surface area, so that the repulsive force between the particles is maximized, so that they are not agglomerated with each other and are helpful in redispersion of other pigments. Therefore, Comparative Example 1 using the ABn-type silicone block copolymer alone showed good pigment dispersibility but poor redispersibility. In Comparative Example 2 using dry silica alone, redispersion was observed, but pigment dispersibility was poor 2 and Fig. 3).

[Test Example 2] Comparison of spreadability, spreadability, adhesion speed

In order to confirm spreadability, spreadability and adhesion speed upon application of the makeup cosmetic composition of the present invention, the sensory evaluation of sensation in Examples 1 to 5 and Comparative Examples 6 to 7 was conducted on 20 professional panelists, 5 points scale) are shown in Table 4 below.

Example 1 Example 2 Example 3 Example 4 Example 5 Comparative Example 6 Comparative Example 7 Spreadability 4.6 4.5 4.3 4.5 4.4 3.7 1.9 Brittle 4.4 4.5 4.4 4.2 4.3 3.2 1.1 Adhesion speed 4.2 4.1 4.2 4.1 4.3 1.7 3.8 <Evaluation Criteria for Variability> 5 points: Very well spread, 4 points: Good spread, 3 points: Average, 2 points: Not spread well, 1 point: Not very straightened

<Evaluation criteria> 5 points: Very good, 4 points: Good, 3 points: Average, 2 points: Not well, 1 point: Very unbalanced

<Criteria for evaluation of adhesion speed> 5 points: very fast, 4 points: fast, 3 points: normal. 2 points: Slow, 1 point: Very slow

As can be seen from Table 4, Comparative Example 6, which is a typical water-based makeup composition, showed favorable spreadability and spreadability, but Comparative Example 7, which is an oil-dispersed makeup composition having a slow adhesion rate and stabilized with wax, And it was not good.

On the other hand, Examples 1 to 5, which are the liquid oil-dispersible makeup compositions of the present invention, are different from the oil-in-water type makeup compositions which are stabilized with the wax-stabilized Comparative Example 6 and the oil-in-water type makeup compositions, The advantages of the makeup composition are as follows. As a result of complementing the disadvantages, the initial application has excellent spreadability and spreadability, and has a high adhesion speed and a short feeling of use which shortens the makeup speed.
