Experimental example

1. Sponge impregnation weight loss test of cosmetic composition

The weight of 10 polyurethane sponges and empty container (sponge + empty container) was measured and recorded, and 15 g of the cosmetic composition prepared in Example 1 was immersed in each of 10 containers and polyurethane sponge. Weight (sponge + empty container + contents) were measured and recorded.

After all the weights were recorded, the weights were measured and recorded daily for 2 weeks after storage in a 45°C thermostat. The measured values are shown in Table 2 below, and the reduction rate of each of 10 was obtained by the following method.

<How to calculate weight loss>

Content loss (%) = Initial filling capacity - Initial filling capacity - (Initial empty container capacity - Last empty container capacity) / Initial filling material capacity - Initial filling material capacity * 100

measurement date 0 days 1 day 2 days 3 days 4 days 5 days 6 days 7 days 2 weeks Content reduction (%) One empty container weight 16.796 Empty container + content weight 31.752 31.749 31.748 31.747 31.747 31.747 31.747 31.747 31.743 0.006 2 empty container weight 16.767 Empty container + content weight 31.745 31.744 31.744 31.743 31.743 31.743 31.743 31.742 31.742 0.002 3 empty container weight 16.712 Empty container + content weight 31.453 31.45 31.45 31.451 31.451 31.451 31.451 31.451 31.448 0.002 4 empty container weight 16.834 Empty container + content weight 31.909 31.906 31.906 31.905 31.905 31.905 31.905 31.904 31.901 0.005 5 empty container weight 16.828 Empty container + content weight 31.766 31.763 31.763 31.763 31.763 31.763 31.763 31.762 31.761 0.002 6 empty container weight 16.753 Empty container + content weight 31.584 31.583 31.583 31.583 31.582 31.582 31.582 31.582 31.582 0.001 7 empty container weight 16.826 Empty container + content weight 31.705 31.705 31.704 31.705 31.705 31.705 31.705 31.705 31.7 0.005 8 empty container weight 16.813 Empty container + content weight 31.929 31.922 31.921 31.921 31.921 31.921 31.921 31.92 31.919 0.003 9 empty container weight 16.788 Empty container + content weight 31.822 31.821 31.821 31.821 31.821 31.821 31.821 31.82 31.817 0.004 10 empty container weight 16.85 Empty container + content weight 31.941 31.936 31.935 31.935 31.935 31.935 31.935 31.931 31.925 0.011 11 empty container weight 16.808 16.802 16.801 16.804 16.804 16.804 16.804 16.803 16.804

As a result of the weight loss test, the content weight loss % ranged from 0.002 to 0.011%, with an average of 0.004%. When the emulsion is deposited using the same container and the same sponge, the content loss % is measured from an average of 0.4% to a maximum of more than 1%.

From these results, it can be confirmed that it is possible to apply to various containers because there is no problem with any container or any sponge, and there are few restrictions on the container.

2. Comparison of coverage according to powder content of cosmetic composition

After taking 0.5 g of each of the cosmetic compositions of Example 1 and Comparative Example 1 and applying them to the back of the hand, the results are shown in FIG. 2 . As shown in the photo, it can be confirmed that the non-aqueous composition can express higher coverage.

This is because the cosmetic composition of the present invention may contain a large amount of powder compared to an emulsion having a powder content of 50% or more and a powder content of about 30%. In other words, it has less restrictions on the powder content, so it has a higher coverage than an emulsion and can express various feeling of use.

3. Comparison of drop and impact tests after sponge deposition of cosmetic compositions

After each 15 g of the cosmetic composition of Example 1 and Comparative Example 1 was immersed in the same container and the same polyurethane sponge, combined with all containers, and after free fall 3 times from a height of 1 m, a photograph of the impregnated state of the impregnated contents is shown in Figure 3 is shown in

In the case of the emulsion, it was confirmed that the contents could not be put on the sponge and discharged out of the sponge when tilted or an impact was applied because the emulsion had a low viscosity. However, when the non-aqueous contents are deposited, it can be confirmed that the contents are well deposited on the sponge and support the contents in the same state as before dropping. Since the sponge is well immersed, superiority can be seen in maintaining the safety of the contents even if the contents leak or drop.

In a similar test, 15 g of each of the cosmetic compositions of Example 1 and Comparative Example 1 were immersed in the same container and the same polyurethane sponge, and then shaken with hands 10 times to give an external impact. 4 is shown.

The shaking shock is similar to the drop shock, and when an impact is applied, the contents cannot be contained in the sponge and are discharged out of the sponge. .

4. Sensory evaluation after deposition according to the type of sponge of the cosmetic composition

Two polyurethane sponges with hardness of 40 and 90 and NBR sponges were respectively deposited with 15 g of the cosmetic composition of Example 1 3 samples, and 15 g of the emulsion cosmetic composition of Comparative Example 1 was deposited on a polyurethane sponge. , the preference was evaluated for the coverage, the texture of the sponge, and the spreadability.

Preference for each sample was conducted as a questionnaire consisting of sensory evaluation (5-point scale method), and very good 5 points, good 4 points, normal 3 points, bad 2 points, and very bad 1 point. An evaluation result is shown in FIG.

In the case of sensory evaluation, in the items of coverage and adhesion, the sponge on which the non-aqueous cosmetic composition of Example 1 was deposited received higher scores than the emulsion. On the other hand, since the non-aqueous cosmetic composition has a high viscosity and the emulsion composition has a low viscosity, the emulsion composition of Comparative Example 1 received a higher score for the amount of application or pickup.

Regarding the texture of the sponge, the sponge with low hardness received high scores regardless of the contents.

5. Measurement result of deposition hardness according to sponge type of cosmetic composition

Two polyurethane sponges having hardness of 40 and 90 and three samples each in which 15 g of the cosmetic composition of Example 1 was deposited on an NBR sponge, and one sample in which 15 g of the emulsion cosmetic composition of Comparative Example 1 was deposited on a polyurethane sponge, one sample It was stored in a constant temperature bath at 25° C. for more than one day so that it could be sufficiently deposited. After separating the container and the sponge, the hardness of the sponge in which the contents were deposited was measured using an F-ASKER F-type hardness meter, and the results are shown in Table 3.

Example 1 - PU
(Hardness 90) Example 1 - PU
(Hardness 40) Example 1 - NBR Comparative Example 1 - PU
(Hardness 90) Sample No.1 92 75 68 44 Sample No.2 87 67 61 44 Sample No.3 90 71 66 45 Average 89.6 71 65 44.3

In Table 3, it can be seen that the hardness of the non-aqueous cosmetic composition of the present invention is maintained above a certain level after immersion no matter which sponge is applied.
