A method of incorporating the water-dispersed polymer in the aqueous phase is as follows. The aqueous components were preliminarily mixed with an agi-mixer while being heated to 60 to 70 ° C to dissolve the crystals in a crystal-free liquid phase. Thereafter, the stirring speed of the agitator was adjusted to 200 to 500 rpm, Polymer was added. Through this, the water dispersion polymer on the powder was uniformly dispersed and wetted to increase the dispersing and increasing efficiency of the water dispersion polymer. The increased water phase was slowly added to the prepared oil phase component at a rate of 100 to 1000 ml / min to make the emulsion of the water phase component have a uniform size.

The oil phase was heated to 85 to 90 DEG C by heating a beaker containing oil phase components such as oil, wax, solid powdery pigment, surfactant and dispersant, and the oil phase component was dispersed. The mixture was homomixed with a homomixer (Mark II , Manufacturer: PRIMIX Japan, sale place: chaesse).

[ Experimental Example 1] Cosmetics Weight loss test

The contents of the cosmetic compositions prepared in Comparative Examples 1 to 2 and Examples 1 to 4 were subjected to a weight loss test. The weight loss test was performed with an electronic balance over time. The units are expressed as a percentage of the weight loss of the contents over time divided by the weight of the initial contents (15 g). The results are shown in Table 2 and FIG.

division 1 day(%) 4 days (%) 13 days (%) 27 days (%) Comparative Example 1 0.37 1.40 4.40 8.13 Comparative Example 2 0.30 1.27 4.20 8.01 Comparative Example 3 0.32 1.28 4.1 7.8 Example 1 0.31 1.33 3.60 6.20 Example 2 0.28 1.40 3.73 6.07 Example 3 0.25 1.20 3.20 4.30 Example 4 0.24 1.35 3.09 4.20

As can be seen from Table 2 and FIG. 1, when comparing Comparative Example 1, Example 1 and Example 3, it can be seen that the content of the cosmetic ingredient decreases with time as the content of the water-wise thickening agent increases. This means that in a water-in-oil type solid foundation using an aqueous phase enhancer, it is possible to give sufficient moisture and refreshing feeling to the cosmetic prepared through this without worrying about the content shrinkage due to the loss of contents over time do.

In the Comparative Example 1, Comparative Example 2, Examples 1 and 2, and Examples 3 and 4, there was no change in the content of the cosmetic ingredients according to the content of the oil phase components. However, The hardness is increased, and the volatilization of the upper component of the internal phase is complemented to some extent. However, the higher the amount of the oil component in the make-up cosmetics, the less the amount of the content will be reduced, but there is a disadvantage that the cosmetics have a thick or thick feeling when used.

[ Experimental Example 2] Feeling Measure

The sensation of use (moistness and refreshing feeling) was evaluated through a panel test in order to examine the feeling of use of each of the makeup cosmetics manufactured in Example 1 and Comparative Example 1, and the results are shown in Table 3 below. Panelists were 20 women in their mid-to-late 20s and 30s.

Example 1 Comparative Example 1 Comparative Example 2 Comparative Example 3 Moistness 4.3 2 2.7 2 Refreshing feeling 4.1 One 2 1.8 Synthesis 4.2 1.5 2.4 1.9

As can be seen from the above Table 3, the cosmetic prepared according to the present invention (Example 1) exhibited a very satisfactory feeling in terms of moisturizing and refreshing sensation as compared with Comparative Example 1.

[ Experimental Example 3] Clinical evaluation

The clinical evaluation was made to objectively determine the efficacy of the makeup cosmetic preparation prepared in Example 1 above. Color persistence, skin uniformity, skin gloss, and pore coverage were evaluated, and the results are shown in Table 4 and FIG. The clinical institution is ELID Co., Ltd. The panelists who participated are 20 women in their mid-thirties and middle-to-late 30s. (Clinical Report CSR-M2S-41274)

To evaluate the color persistence, skin uniformity, and skin luster of the sample, the face was photographed (cross-polarized and parallel) using Visia-CR (Canfield, USA) and image analysis software (Image-Pro Plus, USA) Respectively. In order to evaluate the skin pores for the samples, the area of the ball was photographed using PRIMOS high resolution (GFM, Gemany) and analyzed using PRIMOS software (PRIMOS version 5.6E). The measurement was carried out before the sample application, immediately after the application, 10 hours after the application, and 12 hours after the application.

The mean and standard deviation values of H (Hue), S (Saturation) and V (Value) of the test site were derived using an image analysis program (Image-Pro Plus, USA) The color persistence was evaluated by the mean value, the color change rate after the application of the sample, and the skin uniformity was evaluated using the standard deviation value. In case of skin glare analysis, evaluation was made using the automatic bright object value of the test site.

For the measurement of skin pores, PRIMOS high resolution and software were used. Subjects were asked to wash their face with a cleanser and then stabilized for 30 minutes under constant temperature and humidity conditions. Respectively. In order to prevent the contraction relaxation and movement of the measurement site, the face of the subject was fixed to a specially designed fixed set of PRIMOS measurement equipment. The three-dimensional measurement of PRIMOS changes the parallel projection stripes projected onto the skin according to the height difference of the skin surface, and the degree of change is quantitatively computed by computer. At this time, if the variable value Ra is decreased, the skin pore is improved.

The paired t-test and wilcoxon test were used to confirm the significance of the difference between pre-treatment and post-treatment by 5% (p <0.05). Statistical analysis program was SPSS PASW statistic 18.
