The results are also shown in Table 1.

(Production method)
Components (A), (B), (C) and (F) were mixed and stirred at 60 ° C. to obtain an oil phase. Components (G) and (E) were mixed and stirred at 60 ° C. to obtain an aqueous phase. The oil phase was added to the aqueous phase, mixed and stirred, cooled to 50 ° C., and component (D) was added and stirred. Then, it cooled to room temperature and obtained the skin cleansing composition.

(Evaluation method)
(1) Detergency for oily mascara:
As an oily mascara (waterproof mascara), Kose Sports Beauty Facio Powerstay Mascara (Karl Long) BK001 (trade name) 0.005 g is uniformly applied on a slide glass in a circular shape with a diameter of 1.2 cm and left for 2 hours. And dried. About 0.05 g of each skin cleanser composition is placed on an oily mascara and massaged for 10 seconds in a finger-shaped circle, and then a cotton dress (Lily Bell Lilianpuff / Lily of the valley). ) Was wiped off with a force of constant pressure (7.8 kPa), and the mascara dropped on the slide glass was visually evaluated for the fall of the mascara and evaluated in the following five stages. Evaluation was determined by the total score of five professional panelists.
5: Can be dropped very well.
4: Can be dropped well.
3: Can be dropped slightly better.
2: Cannot drop very well.
1: Cannot drop well.

(2) No skin stickiness immediately after wiping:
After soaking 4 g of each skin cleansing composition uniformly in cosmetic cotton, the face to which the foundation (Sofina Prima Vista Liquid Foundation Ocher 05. The same foundation is also used in the following evaluations) was wiped off, and 15 seconds after the wiping. The non-stickiness of the skin was subjected to sensory evaluation in the following five stages. Evaluation was determined by the total score of five professional panelists.
5: There is no stickiness.
4: Almost no stickiness.
3: Slightly sticky.
2: There is a little stickiness.
1: There is stickiness.

(3) Quick speed after wiping off:
After soaking 4 g of each skin cleansing composition uniformly in cosmetic cotton, wipe the face to which the foundation is applied, and immediately after wiping it, the speed until the skin becomes sticky is sensed in the following five stages. did. Evaluation was determined by the total score of five professional panelists.
5: Very fast.
4: Fast.
3: Slightly early.
2: Slightly slow.
1: Slow.

(4) Natural moist feeling after wiping off:
After soaking 4 g of each skin cleansing composition uniformly in cosmetic cotton, the face to which the foundation was applied was wiped off, and the moist feeling of the skin 15 seconds after the wiping was sensory evaluated in the following five stages. Evaluation was determined by the total score of five professional panelists.
5: There is a natural moist feeling.
4: There is a natural moist feeling.
3: There is a little natural moist feeling.
2: There is not much moist nature.
1: There is no natural moist feeling.

Example 11
