Assessment Methods

(1) Water retention capacity: The electrical conductivity of the skin surface was measured using a Corneometer (Courage + Khazaka, GmbH, Germany), and the measurement temperature was 25° C. and Examples 1 to 6 and Comparative Example 1 A certain amount (0.03 g/16 cm ² ) of the cosmetic composition was applied to 30 subjects, and the moisture content of the skin was measured before application, 1 hour after application, and 3 hours after application, and is shown in Table 2 below.

(2) Sensory evaluation of skin irritation: 45 g of the cosmetic compositions of Examples 1 to 6 and Comparative Example 1 were applied to the entire face, dried and removed, and the skin irritation of the cosmetic composition was sensory based on the redness of the skin by a 5-point scoring method evaluated. The above experiment was repeated 5 times, and the average thereof is shown in Table 2 below. The redder the skin, the greater the skin irritation, and the lower the score.

(3) Antioxidant evaluation: DPPH radical (free radical) scavenging experiment was performed to measure antioxidant activity. 0.5 ml of 0.2 mM DPPH (1,1-diphenyl-2-picrylhydrazyl) was added to a sample solution of 2.0 ml of the cosmetic composition of Examples 1 to 6 and Comparative Example 1, stirred and left for 30 minutes, and then absorbance at 517 nm was measured. measured. The electron donating effect was expressed as a decrease in absorbance between the addition and non-addition groups of the sample solution. The resulting free radical scavenging ability was calculated by Equation 1 below and shown in Table 2 below. The higher the free radical scavenging ability, the higher the antioxidant effect.

As shown in Table 2, Examples 1 to 6 containing perilla extract smooth moisture supply to the skin to increase skin moisture and excellent retention, whereas Comparative Example 1 showed poor skin moisturizing and retention power. can Examples 2 to 6 containing the lotus root extract may reduce skin irritation, and Examples 3 to 6 containing oleic acid may increase the absorption rate of the perilla extract to further increase skin moisture. Examples 5 to 6 containing potassium carbonate can prevent oxidation of oil and fat components included in the cosmetic composition, thereby increasing skin moisture. Example 6 containing perilla hot water extract in the solvent can maximize skin moisturizing power and provide a cosmetic composition that minimizes skin irritation.

Assessment Methods

(1) Water retention ability: The electrical conductivity of the skin surface was measured using a Corneometer (Courage + Khazaka, GmbH, Germany), and the measurement temperature was 25° C. and Examples 6 to 9 and A certain amount (0.03g/16cm ² ) of the cosmetic composition of Comparative Example 2 was applied to 30 subjects, and the moisture content of the skin was measured before application, 1 hour after application, and 3 hours after application. It is shown in Table 4 below.

(2) Sensory evaluation of skin irritation: 45 g of the cosmetic compositions of Examples 6 to 9 and Comparative Example 2 were applied to the entire face, dried and removed, and the skin irritation of the cosmetic composition was sensory based on the redness of the skin by a 5-point scoring method evaluated. The above experiment was repeated 5 times, and the average thereof is shown in Table 4 below. The redder the skin, the greater the skin irritation, and the lower the score.

(3) Evaluation of cosmetic composition removal efficiency: After washing hands with purified water, 0.1 g of Gabo Metal Co., Ltd.'s silver powder (product name: SP-002SM) was spread on the back of the hand, 15 g of the cosmetic composition was applied to the back of the hand, dried and removed. After the cosmetic composition was removed, the conductivity of the purified water was measured using an EC meter of Eurobaing. The above measurement was repeated 5 times and the average value (unit: μS) is shown in Table 4 below. The general conductivity of purified water is 0 μS, and the higher the conductivity, the more the cosmetic composition that has not been removed.

As shown in Table 4, it can be seen that Examples 7 to 11 containing sodium carbonate can easily remove the cosmetic composition, whereas Comparative Example 2 has low removal efficiency of the cosmetic composition. Examples 10 to 11 containing sodium pyrophosphate can provide a cosmetic composition that can be easily removed so that impurities do not remain when the cosmetic composition is removed while preventing skin irritation due to an increase in the pH of the cosmetic composition.

However, this is presented as a preferred example of the present invention and cannot be construed as limiting the present invention in any sense.

Content not described here will be omitted because it can be technically inferred sufficiently by a person skilled in the art.
