EXPERIMENTAL EVALUATION EXAMPLE

(14) Using the low viscosity cosmetic composition prepared through examples 1, 2 and 3, a comparative experiment was made on a sponge impregnation material cosmetic ingredients and a low viscosity cosmetic composition stored in a receiving member with a sheet-type film forming member without using a sponge.

(15) In the case of a sponge impregnation material, a cushion-type container (Pumtech) and a sponge (Coreapuff) available on the market were used, and for the receiving member of the present disclosure, the same container as a container containing a sponge impregnation material impregnated with a cosmetic composition was used, and for the sheet-type film forming member of the present disclosure, those of examples 4-7 were used.

Experimental Example 1: Test of an Amount of Contents Filled and an Amount of Residues

(16) In the case of an amount of contents filled, after the sponge impregnation material was impregnated with the content of example 2 in the same container, and stored in the receiving member with the sheet-type film forming member (example 5 applied), the weight at the time when the flow or leakage of the content in the container standing upright does not occur was measured and compared, and in the case of an amount of residues, after the same container was filled with 15 g, followed by impregnation, twenty female customers in their twenties to forties were allowed to use by a method of using the content using a puff until it is impossible to apply makeup, and a ratio of the amount of residues was measured and averaged.

(17) TABLE-US-00003 TABLE 3 Amount of contents Amount of filled (g) residues (%) Sponge impregnation material 16.28 28.3 cosmetic ingredients Cosmetic composition stored 20.42 13.3 in a receiving member with a sheet-type film forming member

(18) As a result, as can be seen from Table 3, in the case of the present disclosure, an amount of contents filled is large, enabling compact container design for the same amount of contents filled, and an amount of residues is low during use to allow customers to use a larger amount of contents, resulting in economic efficiency.

Experimental Example 2: Test of Amount of Contents Dispensed

(19) In the case of the impregnation material cosmetic ingredients, the content needs to be transferred from the impregnation material surface to the puff well for customers' convenient use. After the sponge impregnation material was impregnated with the content of example 2 and 15 g of the content of example 2 was stored in a cosmetic with the sheet-type film forming member of example 5, twenty female customers in their twenties to forties were allowed to use using a ruby cell puff, and an amount of transfer to the puff each time they use was measured and compared in the form of a graph as shown in FIG. 3. As an amount of contents filled and a deviation were too large in each customer for the first five times of use, an amount of contents used was measured and averaged according to the usage count from the sixth use.

(20) As a result, as shown in FIG. 3, as the usage count increases, the cosmetic of the present disclosure has a higher quantity dispensed and a smaller reduction width relative to an initial quantity dispensed than the cosmetic including the sponge impregnation material, and thus, an advantage is that convenient makeup is achieved during continuous use.

Experimental Example 3: Test of Sensorial Feeling and Makeup Effect

(21) Using the content of example 2, to conduct a comparative experiment for makeup effect and sensorial feeling on the sponge impregnation material cosmetic ingredients (A) and the cosmetic (B) including the sheet-type film forming member (example 5 applied), twenty female customers in their twenties to forties were allowed to continuously use using a ruby cell puff, and each of spreadability, moisturized feeling, coverage, makeup convenience, and makeup effect satisfaction in the first week, the third week, and the fifth week was investigated, and evaluation indexes are as follows:

(22) 1: Very bad

(23) 2: Bad

(24) 3: Moderate

(25) 4: Good

(26) 5: Very good

(27) TABLE-US-00004 TABLE 4 First week Third week Fifth week A B A B A B Spreadability 3.7 4.2 3.2 4.0 2.8 4.1 Moisturized 3.8 4.4 3.2 4.1 3.0 4.0 feeling Coverage 3.6 4.3 2.9 4.1 2.4 3.9 Makeup 3.6 4.5 3.0 4.3 2.5 4.2 convenience Makeup effect 3.7 4.4 3.0 4.2 2.6 4.1 satisfaction

(28) As a result of the customer test, similar to experimental example 2, due to a high quantity dispensed, satisfaction with B was higher than the sponge impregnation material cosmetic ingredients and B obtained noticeably excellent results over time.

Experimental Example 4: Leakage Test at Varying Thickness of Film Forming Member

(29) Samples were prepared in which 15 g of the content prepared at the viscosity described in the above Table 1 was stored in the receiving member with the sheet-type member as shown in Table 2. When the container stands erect in a constant temperature tank of 25 degrees, a leakage test was conducted to determine whether the content flows out of the sheet-type film forming member and gets the container contaminated, or the content does not flows out and the container remains clean.

(30) TABLE-US-00005 TABLE 5 Cosmetic ingredient content Compar- Compar- film forming Exam- Exam- Exam- ative ative member ple 1 ple 2 ple 3 example 1 example 2 Example 4 No leak No leak No leak Leak No leak occurred Example 5 No leak No leak No leak Leak No leak occurred Example 6 No leak No leak No leak Leak No leak occurred Example 7 No leak No leak No leak Leak No leak occurred Comparative Leak Leak Leak Leak Leak example 3 occurred occurred occurred occurred occurred Comparative Leak Leak Leak Leak No leak example 4 occurred occurred occurred occurred Comparative Leak Leak Leak Leak Leak example 5 occurred occurred occurred occurred occurred

(31) As a result of the leakage test, as can be seen from Table 5, in the case of examples, when the viscosity is 1000 cps or less like comparative example 1, or when the entire thickness is 0.4 mm or less like comparative examples 3, 4 and 5, leakage occurred in all, no matter whether the fibers of the film forming member are dense. As the viscosity of the cosmetic ingredients increases or the thickness of the film forming member increases, stability against leakage is high. However, when 3.0 mm or more is used like comparative example 6, leakage stability may be excellent but the thickness is too large, failing to tighten the same test container, and due to forced tightening, the content leaked out of the container at the time of content impregnation.

Experimental Example 5: Test of Sensorial Feeling vs Viscosity of the Content

(32) A sample (example 5) was prepared by filling the container with the content prepared at the viscosity described in the above Table 1 and covering an opening with the film forming member. Changes in sensorial feeling at varying viscosity were compared together in twenty women aged twenties to forties, and evaluation indexes are the same as the method of experimental example 3.

(33) TABLE-US-00006 TABLE 6 Exam- Exam- Exam- Comparative Comparative ple 1 ple 2 ple 3 example 1 example 2 Spreadability 4.2 4.2 4.0 3.7 3.1 Moisturized 4.3 4.2 4.2 3.8 2.8 feeling Coverage 4.0 4.1 4.1 3.5 4.1 Makeup 4.1 4.2 4.3 2.6 2.7 convenience Makeup effect 4.1 4.3 4.2 3.2 2.8 satisfaction

(34) As can be seen from Table 6, in the case of the present disclosure, when viscosity is as low as 1000 cps or less like comparative example 1, during use by customers, makeup convenience and makeup effect satisfaction is found relatively much lower due to too low viscosity. Also, it can be seen that comparative example 2 having viscosity of 7000 cps or more has a significant reduction in sensorial feeling and makeup effect in all the items except coverage, when compared to example 1-3.
