Description

[Technical Field]

[0001] This invention relates to a skin cleansing composition. [Background technology]

[0002] Conventionally, there has been research into detergent compositions that have high cleansing power against makeup, reduced stickiness, and a superior user experience. For example, Patent Document 1 describes a skin cleansing composition containing polyoxyethylene fatty acid ester and polyoxyethylene glycerin fatty acid ester, which has excellent cleansing power and reduces stickiness of the skin after use. Furthermore, Patent Document 2 describes a transparent liquid cleansing cosmetic containing a specific nonionic surfactant, an oil, a polyhydric alcohol, a clay mineral, and an acidic polysaccharide, which does not drip when applied, has excellent adhesion, leaves a clean feeling without oiliness, and exhibits a high cleansing effect.

[0004] However, conventional cleansing compositions had the problem of causing discomfort or friction on the skin when wiping away makeup. Therefore, we considered incorporating water-soluble polysaccharides to reduce friction during wiping. However, although we were able to reduce friction during wiping, we encountered problems with transparency, especially at low temperatures. [Means for solving the problem]

[0005] The present inventors have found that by using, together with a polyoxyethylene fatty acid ester, a polyoxyethylene glycerin fatty acid ester, and a water-soluble polysaccharide, a carboxyvinyl polymer which may be alkyl-modified, a skin cleansing composition with a reduced frictional feeling during wiping and excellent transparency and storage stability can be obtained, and thus completed the present invention.

[0040] Examples 1-9 and Comparative Examples 1-2 Skin cleansing compositions with the compositions shown in Table 1 were prepared, and their cleansing power, lack of stickiness on the skin after wiping, lack of friction during wiping, transparency, and storage stability were evaluated. The results are also shown in Table 1.

[0041] (Manufacturing method) Components (A), (B), (C), and (E) were mixed while stirring until homogeneous. Then, potassium hydroxide was added to the mixture, followed by the addition of a mixture of component (D) and the remaining components to obtain a skin cleansing composition.

[0042] (Evaluation method) (1) Cleaning power: A lip stick (Kanebo N Rouge PK-155) was applied at 1.4 mg / cm2 in an area of 3 cm × 3 cm on the inner skin between the wrist and the elbow of the forearm and left for 30 minutes. Then, 2.0 g of each skin cleansing agent composition was impregnated into a cotton (Kanebo Beautyworks Daily Cotton 45 mm × 65 mm), and the area was repeatedly wiped 5 times with the cotton. The skin after wiping was colorimetrically measured for Lab using a color difference meter (CM-2600d, manufactured by Minolta Co., Ltd.), and the cleansing rate was determined from the difference from the colorimetric value of Lab of the skin before applying the lip stick. (Calculation of cleansing rate) · Let the Lab of the skin before applying the lip stick be L st , a st , b st . · Let the Lab of the skin after applying the lip stick be L1, a1, b1. · Let the Lab of the skin after cleansing the lip stick be L2, a2, b2. · Calculate the color difference before cleansing (ΔE1) and the color difference after cleansing (ΔE2) using the following formulas. ΔE1 = { (L1 - L st ) 2 + (a1 - a st ) 2 + (b1 - b st ) 2} 1 / 2 ΔE2 = { (L2 - L st ) 2 + (a2 - a st ) 2 + (b2 - b st ) 2} 1 / 2 · Calculate the cleansing rate using the following formula. Note that a higher numerical value indicates a higher cleansing power. Cleansing rate (%) = { 1 - (ΔE2 / ΔE1)} × 100

[0043] (2) Stickiness of the skin after wiping: Five expert evaluators applied the liquid foundation <KATE Secret Skin Maker Zero (Liquid)> to their faces. They then applied 2g of each skin cleansing agent composition to a cotton pad (using the same cotton pad as in evaluation (1)) and wiped off the liquid foundation. The degree of stickiness on the skin after wiping was evaluated based on the following criteria. The results are shown as the total score from the five expert evaluators. 5: I don't feel any stickiness at all. 4: It doesn't feel sticky. 3: It feels almost completely non-sticky. 2: It feels sticky. 1: It feels very sticky.

[0044] (3) No friction when wiping: Five expert evaluators applied the liquid foundation <KATE Secret Skin Maker Zero (Liquid)> to their faces, then took 2g of each skin cleansing agent composition onto a cotton pad (using the same cotton pad as in evaluation (1)) and wiped off the liquid foundation. The lack of friction during wiping was evaluated based on the following criteria. The results are shown as the total score from the five expert evaluators. 5: I don't feel any friction at all. 4: No friction is felt. 3: You feel almost no friction. 2: I feel friction. 1: I feel a lot of friction.

[0045] (4) Transparency: The transparency of each skin cleansing agent composition, placed in a glass container, was measured immediately after manufacturing (at 20°C). Transparency was measured by measuring the absorbance at 550 nm using a UV-1800 ultraviolet-visible spectrophotometer (manufactured by Shimadzu Corporation). A value closer to 100 indicates greater transparency, while a value closer to 0 indicates greater opacity.

[0046] (5) Storage stability: The transparency of each skin cleansing composition, placed in a glass container, was measured in the same manner as in (4) after being stored for one month at 0°C, 20°C, and 45°C.
