[0057] Compositions having compositions shown in Tables 1 to 4 below were prepared. For these compositions, the viscosity at 30° C. was measured, and for the composition containing a liquid oil component as an emulsion, the average emulsified particle diameter of dispersed oil droplets was measured. The results are shown in Tables 1 to 4.

[0058] Then, 20 professional judges used these compositions to conduct practical use tests. The test items are moisturizing feeling, absorbability to the skin, whether it is sticky when dry, and whether it is astringent when dry. Each professional judge evaluates each test project based on the following scoring criteria, and divides it into 4 grades according to the overall plan of scoring. The ranking results are shown in Table 1 to Table 4 together.

[0059] Scoring criteria:

[0060] 5 points: very excellent.

[0061] 4 points: excellent.

[0062] 3 points: normal.

[0063] 2 points: Poor.

[0064] 1 point: Very poor.

Abstract

It is intended to provide a cleansing cosmetic composition that quickly removes makeup from the skin, is easily applicable onto the skin without dripping from the hand or running on the face during application, and can freshen the skin because of being washed off thoroughly. The present invention provides a cleansing cosmetic composition comprising: (1) 1 to 15% by mass of silicone oil, (2) 1 to 15% by mass of volatile hydrocarbon oil, (3) 5 to 20% by mass of dihydric glycol, (4) 5 to 40% by mass of polyoxyethylene glyceryl fatty acid ester, and (5) 15 to 88% by mass of water, wherein the weight ratio between the silicone oil (1) and the volatile hydrocarbon oil (2) ((1) / (2)) falls within the range of 0.3 to 3 and the composition has a viscosity of 100 to 500 mPas at 25° C.

Description

technical field [0001] The present invention relates to a skin external preparation composition, which contains tranexamic acid, and the composition does not produce stickiness or astringency, and has a moisturizing and absorbable feeling of use. More specifically, it relates to a liquid external skin preparation composition containing tranexamic acids and xanthan gum and adjusting the viscosity of the entire composition to a predetermined value or less. Background technique [0002] Tranexamic acids have an anti-plasmin effect, and are compounded in various cosmetics as active ingredients for improving rough skin, whitening, and the like. In addition, synergistic effects or new effects obtained by combining tranexamic acids with other substances have also been found. An external preparation for skin with the above ingredients, which can prevent darkening of the skin caused by various factors. [0003] Furthermore, Patent Document 2 discloses that skin cosmetics containing...
