Also, when applying the skin cleanser composition to the face, a certain level of viscosity is required, but even if the viscosity of the skin cleanser composition is increased, the viscosity at room temperature decreases, so the viscosity at room temperature The ratio of the difference in viscosity at a high temperature and the temperature increased, the difference in properties at each temperature was large, and there was a problem in storage stability. In addition, when water-insoluble particles or the like were included in order to obtain a washing feeling, it was found that particles were precipitated in the high-temperature storage product, and there was a problem in stability.

When the viscosity exceeded 1600 dPa · s, the measurement was performed under conditions of rotor No. TC, 5.0 rpm and 1 minute.

(2) Viscosity change rate:
The rate of change in viscosity of each skin cleanser composition was determined from the following calculation formula based on the viscosities at 30 ° C. and 40 ° C. measured in (1). The smaller the rate of change in viscosity, the better the storage stability.
[(Viscosity (30 ° C.)) − (Viscosity (40 ° C.))] / [Viscosity (30 ° C.)]

(3) Drip (40 ° C):
A tube container (φ40LD / HD two-layer tube, manufactured by Daiwa Seisaku Co., Ltd.) having a diameter of 5 mm was filled with 30 g of each skin cleansing composition with the cap closed. The opening was fixed to a position 20 cm high without adding a shear, the cap of the opening was removed, and the time (seconds) from the dripping of the liquid to the dripping of the next liquid was measured. The longer the time (seconds) from dripping down to the next dripping of liquid, the more dripping is suppressed, indicating an excellent skin cleansing composition.
In addition, when dripping is evaluated by this method, it is preferably within 60 seconds from the viewpoint of taking out from the tube container.

(4) Pore cleaning power:
The pore detergency was measured using model comedo sebum colored with carbon black (Table 1). Apply 10 μL of carbon black-colored model comedo sebum on a forearm to a circular shape with a diameter of 2.0 cm, and after drying for 30 minutes, add 1.0 g of the skin cleansing composition and drop the index finger 10 times. Massaged lightly and then rinsed lightly with tap water for 10 seconds. The cleaning rate for each skin before applying the model comedo sebum, after applying the model comedo sebum, and after washing the model comedo sebum is measured using a color difference meter (CR-200, manufactured by Minolta). The color was measured and obtained from the following formula.

(Calculation of cleaning rate)
-Lab Lab before applying model sebum is Lst, ast, bst.
-The Lab of the skin after applying the model sebum is L1, a1, b1.
The Lab Lab after washing the model sebum is L2, a2, and b2.
The color difference (ΔE1) before washing and the color difference (ΔE2) after washing are calculated by the following equations.
ΔE1 = {(L1-Lst) ² + (a1-ast) ² + (b1-bst) ² } ^1/2
ΔE2 = {(L2-Lst) ² + (a2-ast) ² + (b2-bst) ² } ^1/2
・ Calculate the cleaning rate from the following formula.
Cleaning rate (%) = {1− (ΔE2 / ΔE1)} × 100

(Preparation of model comedo sebum)
After mixing 95% by mass of the composition shown in Table 1 and 5% by mass of carbon black, the mixture was heated to 50 ° C. and stirred with a stirrer for 1 minute to prepare a model sebum.

(5) Foaming:
Both hands were moistened with water (7 g), and 2 g of the skin cleansing composition was placed on the palm. After adding 5 g of water, both palms were rubbed together and foamed for 10 seconds. The amount of foam was evaluated from the raised foam. The evaluation was made 5 when the 3 expert panelists felt that the amount of foam was very large, and 1 when it felt that the amount of foam was small.

(6) Rinsing property After moistening both hands with water (about 7 g), 2 g of the skin cleansing composition was placed on the palm. After adding about 5 g of water, both palms were rubbed together and bubbled for about 10 seconds. After that, it was rinsed with tap water, and the rinsing property was evaluated from the speed until the slime disappeared. In the evaluation, 5 expert panelists felt 5 when rinsing felt very fast and 1 when they felt that rinsing was slow.

A skin cleanser composition having the composition shown in Table 6 was produced, the viscosity was measured, and dripping, pore cleaning power, foaming and rinsing properties were evaluated, and the stability of water-insoluble particles was evaluated. The results are also shown in Table 6.

(Production method)
(1) Example 21:
At 25 ° C., a solution in which 20 g of component (A) was dispersed in 250 g of component (D) in a propeller stirrer at 350 rpm for 30 minutes, and 16 g of component (B) was dispersed in 287 g of component (D) in a propeller stirrer at 350 rpm for 30 minutes. The solution was mixed and stirred until homogenous at 3000 rpm for 30 minutes. Thereafter, 25 g of lauric acid, 15 g of myristic acid, 27 g of polyoxyethylene lauryl ether acetic acid and 150 g of (E) were added, heated to 80 ° C., stirred with a propeller stirrer at 300 rpm for 5 minutes, and further 27 g of potassium hydroxide aqueous solution and components 63 g of the aqueous solution of (F) was added, mixed for 5 minutes under the same conditions, and cooled to 30 ° C. at 1 ° C./1 minute. Thereafter, a solution in which 20 g of component (G) was dispersed in 100 g of component (D) was added, and the mixture was stirred at a propeller stirrer 300 rpm for 5 minutes to produce a skin cleansing composition.

(2) Comparative examples 4 and 5:
Comparative Example 4 was produced in the same manner as Example 21 except that component (A) was not blended. Moreover, the comparative example 5 was manufactured similarly to Example 21 except not mix | blending a component (B).

(Evaluation methods)
(6) Stability of water-insoluble particles:
100 g of each skin cleansing composition was placed in a glass bottle (model No. PS-No. 11, manufactured by Tokyo Glass Co., Ltd.) having a capacity of 130 mL and stored at 50 ° C. for 1 day. Then, it returned to the state of 25 degreeC, and visually evaluated the state of the water-insoluble particle | grains in a skin cleaning composition by observing a skin cleaning composition from the bottom face of a glass bottle. The evaluation was made in three stages, with one expert paneler based on the state prior to storage, assuming 3 that there was little sedimentation, and 1 if it felt that there was much sedimentation.

Examples 22 to 26
In the same manner as in Example 1, a skin cleanser composition having the composition shown in Table 7 was produced, the viscosity was measured, and dripping, pore cleaning power, foaming and rinsing properties were evaluated. The results are also shown in Table 7.
