[0069] <Moisturizing properties after wiping> The evaluation was carried out in the following manner. 5 points (good): Skin feels moisturized. 4 points: Skin feels slightly moisturized. 3 points: Neither. 2 points: Skin feels slightly dry. 1 point (bad): Skin feels dry.
[0070] The pH of the cleansing composition at 25°C was measured using a tabletop pH meter F-71 manufactured by Horiba Ltd.
[0071] (Viscosity measurement method) Each sample was kept warm in a thermostatic bath at 25°C for 8 hours, and the viscosity was measured using the following measuring equipment. [Measuring equipment] Brookfield Type B viscometer
[0072] <Stability test> Approximately 2 g of the cleansing compositions of the Examples and Comparative Examples were placed in thermostatic baths at 50°C (high temperature) and -10°C (low temperature) and left to stand for 8 hours. After that, the Examples and Comparative Examples that had been left to stand at both the high and low temperatures were visually inspected, and the items of phase separation, discoloration, and crystal precipitation were evaluated on a 5-point scale, and the average scores were used to evaluate the results according to the following criteria.
[0073] <Separation, discoloration, crystal precipitation> The evaluation was carried out in the following manner. 5 points (good): There was absolutely no change in phase separation, discoloration, or crystal precipitation, and the stability was very excellent. 4 points: Some changes were observed in phase separation, discoloration, and crystal precipitation, but there were no problems with use and the stability was excellent. 3 points: Minor changes in phase separation, discoloration, and crystal precipitation are observed, but there are no problems with use and the product is stable. 2 points: Phase separation, discoloration, and crystal precipitation were observed, which were bothersome when using the product. Stability was somewhat poor. 1 point (bad): Significant changes were observed in phase separation, discoloration, and crystal precipitation, and the stability was poor.
[0074] The results are shown in Tables 2 to 4. As shown in Table 2, the cleansing composition of the present invention has excellent cleansing power and stability, and furthermore, it exhibits cosmetic effects such as moisturizing, whitening, and wrinkle reduction. Therefore, the cleansing composition of the present invention has excellent cleansing power and good stability, and can also exhibit cosmetic effects such as moisturizing, whitening, and wrinkle reduction.
