Description

Cosmetic composition containing solubilized nanocomposition {Cosmetic composition of containing solubilized nanocomposition}

The present invention relates to a cosmetic composition in which an aqueous phase part and an oil phase part containing a solubilized nanocomposition are mixed.

The most basic purpose of a cosmetic composition is to replenish the moisture and oil of the skin that is lost every day. In general, a cosmetic composition is composed of an aqueous phase part providing moisture and an oil phase part providing oil. The aqueous phase part contains water-soluble ingredients such as water, moisturizers, and polymers, and the oil phase part contains oil-soluble ingredients such as oil and wax. In a cosmetic composition, the water phase part and the oil phase part exist in an emulsified state. Emulsification refers to one phase including a fine phase surrounded by an emulsifier. In general, an emulsification requires a surfactant because the immiscible phases must be dispersed semi-permanently. do. In general, emulsified cosmetic composition types are largely classified into oil in water (O/W) and water in oil (W/O) types. The water-in-water type is the most commonly used as a general cosmetic composition because of its light, matte feeling of use, ease of manufacture, and excellent dispersion stability in the form of water. However, water-in-water cosmetics have disadvantages such as poor water resistance, slow absorption and stickiness due to the use of thickeners to secure long-term stability of cosmetics, and skin irritation caused by emulsifiers. On the other hand, the water-in-oil type has the advantage of improving the durability of makeup by overcoming the disadvantage that the external oil forms an oil film on the skin and the moisture film of the skin becomes dry and the moisturizing power decreases. However, the water-in-oil type has a heavy feeling of use and stickiness by mixing wax or the like in the oil or oily components of the outer layer to secure stability, and has a problem of low long-term stability due to the decrease in hardness and viscosity of the emulsion over time. Therefore, it is important to properly maintain the aqueous phase and oil phase.

In the case of a conventional cosmetic composition including an aqueous phase part and an oil phase part, it is a formulation that is used by shaking the two-layer phase consisting of the water phase part and the oil phase part, and is characterized in that it can give a feeling of moisture and oil at the same time, but when shaken and used, the water phase part and the oil phase part do not mix. The feeling of applying separately was strong. In order to solve this problem, efforts were made to develop the water phase part and the oil phase part with different ratios, but when mixed and applied to the skin, the feeling of applying the water phase part and the oil phase part separately was strong. Therefore, there is an urgent need to develop a cosmetic composition that can simultaneously give a feeling of moisture and oil while easily mixing the water phase part and the oil phase part into one.

Accordingly, the present inventors have made intensive research efforts to develop a cosmetic composition capable of mixing the water phase and the oil phase. As a result, by applying the solubilized nanocomposition to the cosmetic composition, the feeling of moisture and oil was felt at the same time, and the effect of applying the mixed formulation into one formulation was reproduced.

Therefore, an object of the present invention is an aqueous phase comprising a solubilized nanocomposition; And to provide a cosmetic composition comprising an oil phase.

The present inventors have made intensive research efforts to develop a cosmetic composition capable of mixing the aqueous phase and the oil phase. As a result, by applying the solubilized nanocomposition to the cosmetic composition, feeling both moisture and oiliness, and reproducing the effect of applying the mixed formulation into one formulation, differentiated from the existing cosmetic composition including the aqueous phase and the oil phase A sense of use was achieved.

Preparation Example 3. Preparation of cosmetic composition

The water phase and the oil phase prepared in Preparation Examples 1 and 2 were weighed, respectively, added at a ratio of 7:3, and then mixed. Cosmetic compositions of Examples and Comparative Examples were prepared by filling the mixed cosmetic composition.

Experimental Example 1. Evaluation of application of cosmetic composition

After applying 1 g each of Example 1 and Comparative Example on the back of the hand, spreadability was confirmed and the results are shown in FIG. 1.

As can be seen in Figure 1, in Example 1, it was confirmed that the water phase part and the oil phase part were applied without being separated. On the other hand, in the comparative example, it was observed that the aqueous phase and the oil phase were separated without mixing. Through this, in Example 1 including the solubilized nanocomposition, it was confirmed that the water phase part and the oil phase part were well mixed and the application property was excellent.

Experimental Example 2. Appearance evaluation of cosmetic composition

1g of each of Example 1 and Comparative Example was dropped on a black surface, and the appearance characteristics of the water phase or oil phase appearing on the surface were observed.

As can be seen in Figure 2, in Example 1, the water phase part and the oil phase part were well mixed, and the phenomenon of floating the oil phase part on the water phase part did not occur. On the other hand, in the comparative example, the water phase part and the oil phase part were not mixed, so the oil phase part was agglomerated on the water phase part and showed a floating appearance.

Through this, in Example 1 including the solubilized nanocomposition, the water phase and the oil phase were well mixed, and the separation of the oil phase on the water phase was not observed.

Experimental Example 3. Evaluation of separation rate of cosmetic composition

The separation rates of the aqueous phase and the oil phase of Example 1 in which the solubilized nanocomposition was applied at about 3% and the comparative example in which the solubilized nanocomposition was not applied were measured and compared.

A 40 ml vial container was filled with the ratio of the aqueous phase and the oil phase at 7:3. And the filled cosmetic composition was shaken about 10 times to mix well.

As a result of the experiment, Example 1 including the solubilized nanocomposition showed a slow separation rate, but Comparative Example without the solubilized nanocomposition showed a fast separation rate. Through this, in Example 1 including the solubilized nanocomposition, it was confirmed that the aqueous phase and the oil phase were well mixed and the separation rate was slow.

Experimental Example 4. Evaluation of the feeling of use of the cosmetic composition

The usability of Example 1 and Comparative Example was evaluated. Specifically, after applying the cosmetic composition to 20 adults, sensory evaluation was conducted on the adhesion felt when applied, the rolling feeling, the overall feeling of use, and the overall satisfaction. At this time, the adhesion means that the cosmetic composition is evenly and quickly applied to the skin, and the rolling feeling means that it is applied smoothly. Overall usability and overall satisfaction were based on individual subjective feelings.

3-4 judged excellent; △

2 or less judged as excellent; X

As can be seen in Table 3, the comparative example not containing the solubilized nanocomposition received a low evaluation in adhesion, overall feeling of use and overall satisfaction. On the other hand, Examples 1 to 3 including the solubilized nanocomposition received high evaluation overall. In particular, as the content of the solubilized nanocomposition increased, the adhesion, rolling feeling, overall feeling of use, and overall satisfaction increased, and Example 1, which contained the most solubilized nanocomposition, showed the best effect. Through this, it was confirmed that in the embodiment including the solubilized nanocomposition, the aqueous phase and the oil phase were well mixed and the overall feeling of use was excellent.
