Description

[Technical field]

[0001] The present invention relates to a skin cleansing composition which has an excellent effect of smoothing the skin texture, reducing the visibility of pores, and further has an excellent effect of improving rough skin. [Background technology]

[0002] Conventionally, skin cleaning compositions such as face washes or cleansing agents are more palatable when designed to have high detergency and foaming power during use, and so various skin cleaning agents have been proposed for the method of using anionic surfactants and amphoteric surfactants in combination (see, for example, Patent Documents 1 to 3). However, when the detergency is too high, the lipids and water-soluble moisturizing components that are essentially needed by the skin are washed away, causing a problem that the moisture content of the skin after washing is reduced and the skin becomes dry.

[0003] On the other hand, it is known that when the moisturizing function of the skin is reduced due to aging or external stimuli, the skin becomes dry and rough, and wrinkles and sagging due to reduced firmness and elasticity of the skin are induced, causing the skin texture to become rough. Therefore, it is extremely important to use skin care materials to improve the skin quality and texture, improve the dryness of the skin, and make the skin smooth as a preventive care for various skin conditions that are undesirable from a cosmetic standpoint. In addition to the problem of appearance, it is also known that leaving the skin texture in a rough state can cause a decrease in the skin's inherent moisturizing function and barrier function, and there has been a demand for a method to prevent and improve the roughness of the skin caused by dry skin after washing.

[0004] In order to prevent such skin texture disorder, various cosmetics and foods have been proposed. For example, a skin cleansing composition that retains moisture without causing dryness on the skin after washing (see, for example, Patent Document 4) is known. In addition, in order to suppress rough skin caused by external factors and improve skin texture, cosmetics containing ingredients effective for promoting the metabolism of the skin epidermis, ingredients effective for protecting the stratum corneum, and ingredients that promote the synthesis of hyaluronic acid and collagen have been proposed. From this perspective, anti-aging agents that stably contain linoleic acid that promotes metabolism (see, for example, Patent Document 5), skin texture improving cosmetics that contain sorbitol and / or mannitol and glycerin and / or diglycerin (see, for example, Patent Document 6), skin texture improving cosmetics that contain an oily component characterized by a skin penetration index of 2 or more (see, for example, Patent Document 7), and cosmetics that contain ethyl oleate and have an excellent effect of improving skin texture (see, for example, Patent Document 8) have been proposed.

[0005] All of the above-mentioned conventional techniques have been improved to a certain extent as methods aimed at preventing irregular skin texture, but the method using a skin cleanser requires an appropriate balance of multiple factors, such as improving the skin's barrier function, reducing damage to the skin from external stimuli, and promoting skin turnover metabolism, and has not yet achieved the effect of making pores less noticeable or improving rough skin.

[0008] As a result of intensive research conducted by the present inventors to achieve the above object, they discovered that a component consisting of aloe extract, chamomile extract, and sage extract is effective in smoothing skin texture, reducing the visibility of pores, and further improving rough skin, and thus completed the present invention.

[0009] Furthermore, by including ascorbic acid and / or its derivatives, the skin texture and the conspicuousness of pores are improved dramatically, and by including one or more selected from glycyrrhizic acid and its derivatives, and glycyrrhetinic acid and its derivatives, the improvement of rough skin is improved dramatically.

[0012] In the present invention, "skin texture" refers to the grooves (skin grooves) running vertically, horizontally and diagonally and the ridges (skin mounds) surrounded by the skin grooves when the skin surface is observed under magnification, and "skin texture adjustment" refers to the state in which the skin grooves and ridges are finely arranged, which affects clear and beautiful skin. "Improving pore visibility" refers to making skin pores less noticeable, for example, reducing the size of pore openings, removing keratin plugs, and contracting the skin around the openings to improve pore looseness. "Improving rough skin" refers to improving the barrier function of the skin, for example, suppressing the increase in transepidermal water loss (TEWL) and improving itching and pigmentation caused by inflammatory responses.

[0013] The configuration of the present invention will be described in detail below.

[0014] <(A) Aloe extract, chamomile extract, sage extract> The component (A) used in the present invention is a composition consisting of aloe extract, chamomile extract, and sage extract. Aloe extract is known to have moisturizing effects by softening the skin surface and increasing the moisture content of the stratum corneum, chamomile extract is known to have anti-allergic effects and UV protection effects by absorbing UVB, and sage extract is known to have anti-allergic effects by inhibiting histamine release. In the present invention, it has been found that the combination of these plant extracts improves skin texture, reduces the visibility of pores, and has an excellent effect in improving rough skin.

[0015] The component (A) used in the present invention can be obtained by extraction, either directly or after grinding, with water, a lower alcohol such as ethanol, a polyhydric alcohol such as propylene glycol or 1,3-butylene glycol, a polyhydric alcohol alkyl ether such as diethylene glycol ether, or other polar solvent, or a mixture of these, but is not limited to these.
