The present invention relates to a skin cleanser composition, which contains the following components (A), (B), (C) and (D): (A) 0.05-6 mass% of hydrophobic silica; (B) 0.6~3.5% by mass of water-soluble polymer; (C) 1~15% by mass of anionic surfactant; (D) 50~90% by mass of polyol or polyol ether.

Due to the high demand characteristics of the market in recent years, the conventional skin cleansing composition must be further improved for dripping during use. In addition, when applying the skin cleansing composition to the face, although a certain viscosity or more is required, even if the viscosity of the skin cleansing composition is increased, the viscosity at high temperature will decrease, so the viscosity at room temperature is lower than that at room temperature. The ratio of the difference in viscosity at high temperature becomes larger, the difference in properties at each temperature becomes larger, and there is a problem in storage stability. In addition, in the case where water-insoluble particles are contained in order to obtain the actual feeling of washing, sedimentation of the particles is seen in the high-temperature storage product, and it has been found that there is a problem in stability.

The present invention relates to reducing the ratio of the difference in viscosity between room temperature and high temperature by suppressing the drop of liquid during use and suppressing the decrease in viscosity at high temperature, the storage stability is superior, and the detergency is satisfied, especially Cleansing power, foaming and rinsing paint for pores.

40LD/HD2層管，大和製罐公司製)中依蓋關閉的狀態填充各皮膚洗淨劑組成物30g。使開口部朝下且未施加剪切，固定於高20cm的位置，移除開口部之蓋，在液滴落後計測次一液滴落為止的時間(秒)。液滴落後至次一液滴落為止的時間(秒)越長，則表示抑制液滴垂，為優良的皮膚洗淨劑組成物。 In 5mm diameter tube container (

40LD/HD 2-layer tube, manufactured by Yamato Can Co., Ltd., was filled with 30 g of each skin cleansing composition with the lid closed. Make the opening face down without applying shear, fix it at a height of 20 cm, remove the cover of the opening, and measure the time (seconds) until the next drop after the drop. The longer the time (seconds) until the next drop of the liquid drops, the longer it is that the liquid drips are suppressed, and it is an excellent skin cleansing composition.

In addition, in the case of evaluating the dripping according to this method, it is preferably within 60 seconds from the viewpoint of the detachability of the tube container.

On the forearm, apply 10μL of model acne sebum colored with carbon black into a circle with a diameter of 2.0cm. After drying for 30 minutes, drop 1.0g of the skin cleanser composition, draw a circle with the index finger and gently massage it 10 times. Then, rinse gently with tap water for 10 seconds. The cleansing rate is measured on the skin before the application of model acne sebum, the skin after the application of model acne sebum, and the skin after cleaning the model acne sebum, using a color difference meter (CR-200, manufactured by Minolta) to measure the Lab. The following calculation formula is obtained.

(Calculation of cleaning rate)

‧Set the Lab of the skin before model acne sebum application to Lst, ast, bst.

‧Set the Lab of the skin after applying model acne sebum to L1, a1, and b1.

‧Set the Lab of the skin after washing the model acne sebum to L2, a2, and b2.

‧Calculate the color difference before washing (△E1) and the color difference after washing (△E2) according to the following formula.

△E1=((L1-Lst) ² +(a1-ast) ² +(b1-bst) ² } ^1/2 △E2=((L2-Lst) ² +(a2-ast) ² +(b2-bst ) ² } ^1/2

‧Calculate the cleaning rate from the following formula

Washing rate (%)={1-(△E2/△E1)}×100

(Preparation of model acne 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 stirring bar for 1 minute to prepare model sebum.
