The formulations described in the table above were prepared according to the following steps.

The phases A were weighed together and heated to 80 DEG C with stirring using a Moritz type stirrer until the phases were homogeneous.

Phase B was heated to 80 < 0 > C.

Phase B was slowly added to Phase A with stirring using a Moritz type stirrer and a minimum temperature of 75 캜 was maintained during the addition.

The formulations 1 to 4 of the present invention were each molded to obtain a uniform compact foundation, while the comparative formulations 1 and 2 were filled in a tube to obtain a foundation product.

Each of the compositions of Formulations 1 to 4 of the present invention was also tested for the user. The skin feel and ease of use, such as the water release effect, cooling effect, and melting effect, of the compact foundations 1 to 4 obtained from the composition of the present invention can be determined by twelve consumers using the compact foundation obtained from the composition of the inventive formulations 1 to 4 0.1 g each on the inside of the arm. The consumers were asked to observe the water release effect while applying the foundation, and at the same time to evaluate the cooling effect and the melting effect.

A significant difference was observed between areas of the skin treated with the emulsion compared to the untreated areas, and the treated skin was more moist than the untreated skin.

It is observed that all of the emulsions prepared are excellent in stability, i.e., the bulk viscosity and appearance are well maintained, but the stability of such emulsions decreases with decreasing amounts of cetyl PEG / PPG-10/1 dimethicone in the emulsion. Thus, the emulsion of composition 2 is more stable than the emulsion of composition 3, which itself is more stable than the emulsion of composition 4, which has some water release on the surface of the emulsion.

Example 2

The stability, ease of use, and skin feel of the formulations and comparative formulations of the present invention were evaluated.

The stability of the compositions of the present invention and the comparative formulation was evaluated at 45 캜, 37 캜, and 4 캜 for 8 weeks.

Each of the inventive and comparative formulations described above was also tested for the user. Twelve consumers rated each of the formulations 0.1 g in the arm and assessed skin sensitivity, ease of use, and stability, such as moisture release effect, cooling effect and melting effect of the present invention and comparative formulations. The consumers were asked to score on the effect they wanted to test. 5 indicates excellent, 4 indicates very good, 3 indicates acceptable, 2 indicates unacceptable, and 1 indicates very poor. the results are as follow:

Blends 1 to 4 of the present invention were found to be easy to form into a compact foundation due to their solid texture, thereby allowing consumers to use it as a dispensing tool or one hand for skin makeup. It was very easy for consumers to supplement their makeup of the skin during the day. On the other hand, due to their liquid texture, comparative formulations 1 and 2 placed in tubes are not easy to apply to the skin. They needed to use both hands to apply to consumers.

In terms of skin sensation, it has been found that the present invention and comparative formulations have good water bead release and cooling effects. Blends 1 to 4 of the present invention had an improved fusing effect due to the fact that, during application, the solid formulations of the present invention were converted to a liquid texture on the skin as compared to Comparative Blends 1 and 2.

Finally, the formulations of the present invention and comparative formulations were found to have excellent stability at different temperatures.
