As a result of the weight loss test, the content weight loss was 0.002% to 0.011% and the average weight loss was 0.004%. When the emulsion is immersed in the same container and the same sponge, the% weight loss is measured from an average of 0.4% to more than 1%, which shows that the weight loss is very small and almost does not volatilize.

These results show that the application of any container or sponge is not a big problem, and it is possible to apply to various containers because of the limited container.

2. Comparison of covering power of cosmetic composition according to powder content

0.5 g of each of the cosmetic compositions of Example 1 and Comparative Example 1 was applied to the back of the hand, and the results are shown in Fig. As can be seen from the photograph, it can be seen that the non-aqueous composition can express a higher coverage.

This is because the cosmetic composition of the present invention can contain a large amount of powder as compared with the emulsion containing about 50% or more of the whole powder and having a powder content of about 30%. That is, since the powder content is limited, the covering ability is higher than that of the emulsion, and various feelings can be expressed.

3. Comparison of falling and impact test after sponge deposition of cosmetic composition

15 g of each of the cosmetic compositions of Example 1 and Comparative Example 1 was immersed in the same polyurethane sponge, and then the mixture was immersed in all the containers and then dropped three times at a height of 1 m. Respectively.

Since the emulsion has a low viscosity, it can be confirmed that when the inclination or impact is applied, the contents can not be supported on the sponge and discharged out of the sponge. However, in the case where the non-aqueous content is deposited, it can be confirmed that the contents are well deposited on the sponge and the contents are carried in the same state as before the fall. It is well immersed in the sponge, so even if the contents leak or drop, the superiority of maintaining the safety of the contents can be confirmed.

15 g of each of the cosmetic compositions of Example 1 and Comparative Example 1 was immersed in the same container and 15 g of the same polyurethane sponge in a similar test and then shaken by hand for 10 times to give an external impact. 4.

Shock impact is similar to drop impact. When the impact is applied, the contents can not be supported on the sponge and discharged out of the sponge. When the non-aqueous content is deposited, the contents are well deposited on the sponge, .

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

Three samples of 15 g each of the polyurethane sponge and NBR sponge having hardness of 40 and 90 were immersed in 15 g each of the cosmetic composition of Example 1 and one sample of 15 g of the emulsion cosmetic composition of Comparative Example 1 immersed in a polyurethane sponge, , The coverage, the texture of the sponge, and the spreadability

The preference for each sample was based on a questionnaire consisting of sensory evaluation (5 point scaling method). The results were as follows: Excellent 5 points, Good 4 points, Average 3 points, Poor 2 points, and Poor 1 point. The evaluation results are shown in Fig.

In the covering power and touch feeling items when the sensory evaluation was conducted, the sponge immersed in the non-aqueous cosmetic composition of Example 1 was rated higher than the emulsion. On the other hand, since the non-aqueous cosmetic composition has high viscosity and low viscosity in the case of the emulsion composition, the emulsion composition of Comparative Example 1 has a higher score in terms of the amount of hair growth and the amount of pick-up.

In the case of the texture of the sponge, the low hardness sponge was highly rated regardless of the contents.

5. Results of immersion hardness measurement according to sponge type of cosmetic composition

Three samples in which 15 g each of the cosmetic composition of Example 1 were immersed in two polyurethane sponges of hardness 40 and 90 and an NBR sponge and one sample in which 15 g of the emulsion cosmetic composition of Comparative Example 1 was immersed in a polyurethane sponge were used to prepare a cosmetic composition Lt; RTI ID = 0.0 &gt; 25 C &lt; / RTI &gt; Thereafter, the container and the sponge were separated and the hardness of the sponge immersed therein was measured by using an F-ASKER F type hardness meter. 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 confirmed that the hardness of the non-aqueous cosmetic composition of the present invention is maintained at a certain level or more after immersion regardless of which sponge is applied.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. It belongs to the scope of right.
