As the polymer component, dimethicone, dimethicone/polyglycerin-3 crosspolymer, dipropylene glycol, sodium citrate, and tocopherol were mixed in a weight ratio of 75.38:24:0.50:0.1:0.02 and used.

2. Check the hardness

For the cosmetic composition prepared above, the hardness was checked using a Sun RHEO METER CR-3000EX-L as a measuring device. Hardness analysis conditions are as follows.

1.Adaptor No: 9 (15φ)

2. S. ADJ(=entry distance): 20mm

3. T. Speed: 20mm/min

4. Container: 200g bulk container

5. Storage conditions: 25℃

As a result, Examples 1, 2, 3, 4 and Comparative Examples 1, 2, and 3 all showed a hardness of 20 or more, thereby obtaining a hardness result as high as possible as a pact cosmetic. If the hardness is less than 20, the contents flow down and cannot be made into a pact cosmetic. If the hardness is too high, it is difficult to take the contents and use it.

3. Check application

Also, application properties were confirmed for the cosmetic composition prepared above.

In the case of Comparative Example 1 that did not contain an oil thickener and used only the wax as a thickener, the cosmetic material did not well adhere to the applicator, so the payoff was not easy. In this case, the composition was not applied smoothly and a stiff feeling of use was obtained. In Comparative Example 3, a product capable of pay-off suitable for use as a cosmetic product was made, but the spreadability was insufficient.

However, it was confirmed that Example 1 further contained a polymer component and satisfies the smooth and silky spreadability. In addition, Examples 2, 3, and 4 in which the polymer content was increased were softer and more silky than Example 1.

4. Sensory evaluation

For the compositions prepared through Examples 1 to 2 and Comparative Examples 1 to 3, feeling of use, sealing power and stability were evaluated, and detailed evaluation methods and results are as follows. After the pact cosmetics filled with the contents were stood at 37°C, the flowability was observed and shown in FIG. 1.

As a result, in the case of Comparative Example 1, there was no oil thickener, and only vegetable wax showed a phenomenon in which a large amount flowed down when stored at 45°C for 7 days. In the case of Comparative Example 2, there was no wax and only an oil thickener, and although it flowed less at high temperature, it was difficult to take the contents and did not apply smoothly. In the case of Example 1, the contents hardly flowed down at high temperature and the payoff was good.

<Usability evaluation>

30 professional female panels aged 25-45 years old were divided into two groups, and Examples 1 to 4 and Comparative Examples 1 to 3 were appropriately adjusted in each group and used on both faces, according to the following evaluation criteria. The feeling of use, such as application, nutrition, adhesion, and overall satisfaction felt when applying was evaluated, and the results are shown in Table 2 below.

Among the above criteria, the spreadability is a property that applies smoothly to the skin with a feeling of spreading it on the skin, and includes applying without stickiness or dripping. Nutritional sensation refers to the feeling of giving nutrition and moisture to the skin when applied to the skin. Adhesion refers to the feeling that the composition adheres to the skin by applying it to the skin thinly when applied to the skin. These three criteria increase the value of use as a cosmetic, and in particular, elasticity and adhesion can be important features of functional cosmetic.
