Description

[0001] The present invention relates to a water-in-oil type cosmetic composition for make-up comprising a hydrophilic gelling agent and a polyol,

A hydrophilic gelling agent and a polyol.

Foundation is a facial and neck cosmetics to even out skin tone and smooth skin texture. The foundation can maintain a bright face by selecting a product that matches the color of your skin in various colors. Thin and uniformly applied, it gives the skin a whitening effect and makes the skin texture look good. Foundations include liquid foundation and powder foundation. Powder foundation is the same as existing powder, and the fact type type container is used. It is a medium texture between liquid and powder or solid foundation. When pressed with powder cushion, moist liquid is applied and it is applied to the face. Accordingly, the powder foundation is also called a foundation fact, a cushion fact, and the like. On the other hand, a water drop molding foundation is a formulation in which a water drop effect is generated in which a water-in-oil type foundation emulsion is sprayed onto the skin and emulsion is broken to release water from inside to form water droplets.

Conventional water drop molding foundation formulations have a problem in that the water particles are evaporated and the surface of the skin is dried and the skin is not smoothly rolled. In addition, the conventional water drop molding foundation formulation has a problem that the emulsification system becomes unstable in the process of controlling the emulsifier to cause water to be formed on the surface or flow out. This has a great influence on the stability, and the surface is crushed or the contents are separated, causing problems in the filling process and feeling of use.

Therefore, it is necessary to develop a foundation formulation that can hold the emulsified structure well and improve the moisture retention.

Experimental Example 1: Moisture persistence clinical evaluation

The moisturizing sustainability of the foundation according to Example 1 and Comparative Example 1 was evaluated clinically.

First, five healthy adults with an average age of 24.8 were selected for the test. Before the test, the test area (inside of hump, 2 cm x 2 cm) was washed with lukewarm water. After 30 minutes, the skin moisture content of the test site was measured. 8 μl of the product was applied to the test site, and skin moisture was measured three times immediately after application, 2 hours, 4 hours, and 8 hours after the application. Corneometer (CK electronic, Germany) was used as the measuring device. The rate of change in skin moisture was calculated using the average of three measurements, and then compared with the value before use.

Fig. 1 is a graph showing skin moisture (A.U) immediately after application of foundation, after 2 hours, after 4 hours, and after 8 hours.

2 is a graph showing skin moisture percentage (%) immediately after application of foundation, after 2 hours, after 4 hours, and after 8 hours.

As shown in Figs. 1 and 2, in Comparative Example 1, a moist and moisturizing composition was obtained, but the water content was remarkably high. On the other hand, the foundation of Example 1 not only had higher skin moisture than Comparative Example 1, but also had a superior moisturizing persistence immediately after application.

Experimental Example 2: Evaluation of content reduction according to content of polyol

The weight loss of the foundation according to Example 1 and Comparative Example 1 was evaluated.

Specifically, a container containing 18 g of each of the foundations according to Example 1 and Comparative Example 1 was left at 45 캜 for 7 days, and the degree of loss of contents was calculated. The material of the container was ABS (Acrylonitrile butadiene styrene) for the outer container, and the polypropylene for the inner container and the inner container. The same experiment was repeated 4 or 5 times. The content reduction was calculated by the following formula (1). Table 2 shows the contents loss test results of the product of Example 1. Table 3 shows the results of the content reduction test of the product of Comparative Example 1.

As shown in Tables 2 and 3, the product of Comparative Example 1 was reduced by 0.03% after 7 days, while the product of Example 1 was decreased by 0.01% after 7 days, showing almost no loss. That is, the product of Comparative Example 1 tends to shrink the contents due to the phenomenon that moisture is evaporated due to a high water content, but the product of Example 1 can overcome such disadvantages.

Experimental Example 3: Evaluation of content loss with and without a hydrophilic gelling agent

The weight loss of the foundation according to Example 1 and Comparative Example 2 was evaluated.

Specifically, the foundation according to Example 1 and Comparative Example 2 was allowed to stand at room temperature for 30 days, and the shrinkage of the contents was visually confirmed.

Fig. 3 is a photograph showing the shrinkage of the contents after leaving the foundation of Comparative Example 2 (left) and Example 1 (right) at room temperature for 30 days.

4 is a photograph showing shrinkage of the contents and cracking phenomenon after leaving the foundation of Comparative Example 2 (left, middle) and Example 1 (right) at room temperature for 30 days.

As shown in Figs. 3 and 4, the foundation of Comparative Example 2, which did not contain a hydrophilic gelling agent, exhibited shrinkage of contents after being allowed to stand at room temperature for 30 days. As a result of evaporation of moisture and contents at the upper surface of the contents, Cracks occurred inside the contents. On the contrary, the foundation of Example 1 including the hydrophilic gelling agent showed almost no shrinkage phenomenon and no cracking phenomenon after the contents were kept warm even after being left at room temperature for 30 days. Therefore, it was judged that the foundation of Example 1 has a stabilization system that protects the evaporation of contents with stability of emulsification by including a hydrophilic gelling agent.

Experimental Example 4: Evaluation of hardness and feeling

Experiments were conducted to evaluate the hardness and feeling of use of the foundation according to Example 1 and Comparative Example 1.

First, the hardness was measured using a hardness meter (manufacturer, model name, measurement conditions, etc.). As a result, the hardness of the foundation of Comparative Example 1 was 58.5 ± 1.00 and that of the foundation of Example 1 was 56.7 ± 1.00. Thus, both products obtained hardness results as high as possible as a fact type cosmetic product.

Next, 20 women aged 25-35 years were used to adjust the foundation of Example 1 and Comparative Example 1 to suit both sides of the face. Then, the feeling of moisturizing feeling, feeling of cooling, The feeling of use such as overall satisfaction was evaluated, and the results are shown in Table 4 below.

Among the above criteria, wetting property is a feeling of spreading on the skin, tacky on the skin smooth on the skin, and balding on the skin without flowing down. The feeling of moisturizing is the feeling of giving the skin nutrition and moisturizing when applied to the skin. The feeling of cooling is the feeling that the skin becomes cool when applied to the skin.
