The values ​​for each component in the table represent mass percent. [Table 1] [Table 2] [Table 3]

[0039] [viscosity] The viscosity of the cosmetic preparations described above was measured at 30°C using a BH-type viscometer (No. 6 rotor, 10 rpm rotation speed). The results are shown in Tables 1-3. For samples where hardness was listed in the viscosity column, hardness was measured because it could not be measured with a viscometer. The unit of hardness is Newtons (N). Hardness was measured at 25°C using a Rheotec rheometer (pressure-sensitive shaft 11.3Φ, needle insertion speed 10cm / min, needle insertion depth 10mm).

[0040] [Evaluation of oil separation and cracking] Each cosmetic preparation described above was filled into a resin container primarily composed of polyethylene terephthalate and a glass container, respectively. After being left at 37°C for 4 weeks, the containers and their contents were observed, and oil separation and cracking were evaluated according to the following criteria. The results are shown in Tables 1-3. • Oil floating A: No oil separation was observed. B: A slight oil separation was observed. C: A significant amount of oil separation was observed. • Cracks A: No cracks were observed. B: Slight cracking was observed. C: Cracks were observed in multiple locations.

[0041] [Share resistance] 100g of each cosmetic preparation described above was placed in a beaker and stirred for a set period of time using a propeller stirrer. Afterward, the state of each cosmetic was visually observed and evaluated according to the following criteria. The results are shown in Tables 1-3. A: No oil or water seepage was observed, and the surface condition was good. B: No oil or water seepage was observed, but weak light was reflected from the bulk surface. C: Oil and water seepage was observed.

[0042] [Overall Stability Evaluation] Based on a comprehensive assessment of the results regarding oil separation, cracking, and shear resistance described above, a comprehensive stability evaluation was conducted according to the following criteria. The results are shown in Tables 1-3. A: It has excellent stability. B: Excellent stability. C: There are concerns about stability. Furthermore, in the overall stability evaluation, the absence of oil separation and cracking is more important from a stability perspective than shear resistance. Therefore, products that received a C rating only for shear resistance were given a B rating in the overall evaluation.

[0043] All of the cosmetic compositions prepared in the above examples were non-sticky and non-greasy, and had excellent usability.
