Description

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 are mixed comprising a solubilized nanocomposition.

The most basic purpose of the cosmetic composition is to replenish the moisture and oil of the skin that are lost every day. In general, a cosmetic composition is composed of an aqueous phase that provides moisture and an oil phase that provides oil. The aqueous phase contains water-soluble components such as water, a moisturizer, and a polymer, and the oil phase contains oil-soluble components such as oil and wax. In the cosmetic composition, the aqueous phase and the oil phase exist in an emulsified state. Emulsification refers to a single phase including a fine phase surrounded by an emulsifier. In general, emulsification requires a surfactant because it is necessary to semi-permanently disperse the immiscible phases. do. In general, emulsified cosmetic composition types are broadly classified into oil in water (O/W) and water in oil (W/O) types. Oil-in-water is the most used as a general cosmetic composition because it has a light and matte feeling of use, is easy to manufacture, and has excellent dispersion stability. However, oil-in-water cosmetics have disadvantages such as poor water resistance, slow stickiness and slow absorption due to the use of a thickener to ensure long-term stability of cosmetics, and skin irritation by emulsifiers. On the other hand, the water-in-oil type has an advantage in that the traumatic oil forms an oily film on the skin, and the moisture film of the skin dries, thereby overcoming the disadvantage of lowering the moisturizing power and improving the durability of the makeup. However, the water-in-oil type has a heavy feeling and stickiness by blending wax in the oil or oil component of the outer box to ensure stability, and the hardness and viscosity of the emulsion decrease over time, resulting in low long-term stability. Therefore, it is important to properly maintain the water phase and oil phase.

In the case of a conventional cosmetic composition comprising an aqueous phase and an oil phase, it is a formulation that is used by shaking the two-layered phase consisting of an aqueous phase and an oil phase. It had a strong feeling of being applied separately. Efforts were made to develop different ratios of the aqueous phase and the oil phase to solve this problem, but when mixed and applied to the skin, the aqueous phase and oil phase were applied separately. Therefore, there is an urgent need to develop a cosmetic composition that can provide moisture and oily feeling while the water phase part and the oil phase part are easily mixed into one.

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

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

Preparation Example 3. Preparation of a cosmetic composition

Each of the aqueous phase and oil phases prepared in Preparation Examples 1 and 2 was weighed, added in a ratio of 7:3, and then mixed. The cosmetic compositions of Examples and Comparative Examples were prepared by filling the mixed cosmetic composition.

Experimental Example 1. Evaluation of spreadability of cosmetic compositions

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

As can be seen in FIG. 1 , in Example 1, it was confirmed that the aqueous phase part and the oil phase part were applied without being separated. On the other hand, in Comparative Example, it was observed that the aqueous phase and the oil phase were separated without mixing. Through this, in Example 1 containing the solubilized nanocomposition, it was confirmed that the aqueous phase part and the oil phase part were mixed well and the spreadability was excellent.

Experimental Example 2. Appearance evaluation of cosmetic composition

After 1 g of Example 1 and Comparative Example were dropped on a black surface, the appearance characteristics of the aqueous phase or oil phase on the surface were observed.

As can be seen in FIG. 2 , in Example 1, the aqueous phase and the oil phase were well mixed, so that the floating phase did not occur on the aqueous phase. On the other hand, in the comparative example, the aqueous phase part and the oil phase part were not mixed, and the oil phase part was agglomerated on the aqueous phase part, and thus it appeared floating.

Through this, in Example 1 containing the solubilized nanocomposition, the aqueous phase and the oil phase were well mixed, and the phenomenon that the oil phase was separated and floated on the aqueous phase was not observed.

Experimental Example 3. Evaluation of separation rate of cosmetic composition

The separation rates of the aqueous phase and oil phases of Example 1 to which about 3% of the solubilized nano-composition was applied and Comparative Example to which the solubilized nano-composition was not applied were measured and compared.

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

As a result of the experiment, Example 1 containing the solubilized nanocomposition showed a slow separation rate, but Comparative Example not containing the solubilized nanocomposition showed a fast separation rate. Through this, in Example 1 containing the solubilized nanocomposition, it was confirmed that the aqueous phase part and the oil phase part were well mixed and the separation rate was slow.

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

The feeling of use of Example 1 and Comparative Example was evaluated. Specifically, after applying the cosmetic composition to 20 adults, sensory evaluation was performed with respect to adhesion, rolling feeling, overall feeling of use and overall satisfaction. At this time, the adhesion means that the cosmetic composition is evenly and quickly applied to the skin, and the feeling of rolling means that it is applied smoothly. The overall feeling of use and overall satisfaction were based on an individual's subjective feeling.

<Evaluation criteria>

10 or more judged as excellent; ◎

5-9 judged as excellent; ○

3-4 judged as excellent; △

2 or less judged as excellent; X

As can be seen in Table 3, the comparative example not including the solubilized nanocomposition received low evaluation in adhesion, overall feeling of use, and overall satisfaction. On the other hand, Examples 1 to 3 including the solubilized nanocomposition were generally highly evaluated. In particular, as the content of the solubilized nano-composition increased, the adhesion, the rolling feeling, the overall feeling of use, and the overall satisfaction increased, and Example 1 containing the most solubilized nano-composition showed the most excellent effect. Through this, it could be confirmed that the examples including the solubilized nanocomposite were well mixed with the aqueous phase and oil phase, so that the overall feeling of use was excellent.
