POWDERY COSMETIC COMPOSITION [0002]

The present invention relates to powdered cosmetic compositions in the form of pressed powder.

Skin make-up compositions can be used to provide attractive color to the skin, typically a face, but may also be used to mask skin imperfections such as flare, dots and wrinkles.

The average particle size was measured with Mastersizer 2000 manufactured by Malvern.

For each of Example 1 and Comparative Examples 1 to 4, the powder components shown in Table 1 were mixed in a Henschel mixer for about 10 minutes. The non-powder components (oil, surfactant, UV filter and preservative) shown in Table 1 were added to the mixture and mixed together for about 15 minutes. The mixture was pulverized with a hammer mill. The pulverized powder was filtered with a mesh to form the powder cosmetic composition according to Example 1 and Comparative Examples 1 to 4.

[Evaluation of hardness]

13 g of each of the powdery cosmetic compositions of Examples 1-3 and Comparative Examples 1 and 2 was pressed and pressed at a pressure of 10 kgf / cm ² (first press) and 30 kgf / cm ² (second press) Shaped squeeze powder.

The hardness of each sample thus obtained was measured using Asker Hardness Meter Al type. The results are shown in Table 2 below.

[Evaluation of compressibility]

For each of the samples according to Example 1 and Comparative Examples 1 to 4, a drop test was performed on the ceramic tile at a height of 20 cm. A slice of each sample was measured to calculate the loss of the powder. The results are shown in Table 2 below.

The powdery cosmetic composition of Example 1 exhibited better hardness and compressibility than Comparative Examples 1 and 2. It can be understood that the powdered cosmetic composition of Example 1 has good physical properties even though it contains a comparatively large amount of spherical filler.

[Evaluation of uniformity]

For the samples according to Example 1 and Comparative Examples 1 to 4, 100 g of powder was taken by sponge at a rate of 5 mm / s under the condition of a length of 25 mm, and was subjected to measurement with a Tribo Master TL-201 under the condition of a length of 120 mm A coating test was performed in which the skin model plate (Bio Skin T5) was applied at a rate of 5 mm / s.

The surface of each skin model plate was observed at 1 cm and 5 cm from the application start point. The results are shown in Table 3 below.

Example 1 shows the difference between Ra (1 cm) and Ra (5 cm) smaller than Comparative Examples 1 and 2. This means that the powdered cosmetic composition can be more uniformly applied to the skin as compared with the composition of Comparative Examples 1 and 2.

[Sensory Evaluation]

For the samples according to Example 1 and Comparative Examples 3 and 4, 11 testers under the following criteria were subjected to sensory evaluation for several characteristics.

The averages of the scores for each sample were grouped according to the following criteria. The results are shown in Table 4 below.

OO: 5.0 to 4.0

X: less than 4.0 to 3.0
