Description

Washable cleansing composition self-forming fine and continuous foam}

The present invention relates to a gel-like cleansing composition, more specifically, the foam is formed by itself, the foam is fine and excellent in sustainability to remove skin impurities without irritation, to maintain a smooth and moist skin condition after use It relates to a gel type cleanser composition exhibiting excellent usability.

In general, facial cleansers include a tissue-off type oil-based cleanser and a wash-off type water-based cleanser, and their main purpose is general cosmetics used for cleanliness of the skin. The face wash removes various wastes such as sweat, sebum, dust, and aged keratin, make-up residues and other contaminants on the surface of the skin to keep the skin moist and healthy, resulting in good makeup. If the above impurities remain on the skin, capillaries contract and blood circulation is weakened, the pores become clogged, and the oxygen and nutrient supply necessary for metabolism are disturbed, and the skin becomes unhealthy. Or rashes or blemishes appear, and lipid peroxides accumulate and cause premature aging.

Foam cleansing, a conventional cream-type water-based cleanser, is one of the most used cleansers that cleans the skin and make-up as well as skin wastes, but removes excessive irritation and sebum due to friction between skin during cleansing The skin is easily pulled out and wrinkles are likely to ruin the skin.

In order to ameliorate the above problems, that is, nonionic surfactants such as cocoglucoside, which effectively removes makeup and rinses well in water, are used to prevent excessive sebum removal. These nonionic surfactants also remove skin impurities and moisturize the skin after use. However, these nonionic surfactants are poor in cleansing, so it is difficult to expect clean skin cleansing.

In order to compensate for these problems, research has recently been conducted on facial cleansers that can remove the irritation caused by skin friction by forming fine self-foams and reduce excessive sebum removal while maintaining makeup cleansing power. As an example of such research, US Pat. No. 6,383,998 discloses a cosmetic composition comprising a fluorine-based volatile oil, a surfactant, a water soluble polymer and a humectant.

However, the cosmetic preparation of the US Patent No. 6,383,998 requires a complicated process to stabilize with a surfactant using a fluorine-based volatile oil, etc., and also has a problem that the bubbles of the formulation itself disappears quickly. In particular, the fluorine-based volatile oil has a problem that the bubbles disappear quickly because of high volatility when used as a cosmetic composition, and thus there is a problem in that the bubble persistence even if stabilized with a surfactant.

Therefore, the technical problem to be achieved by the present invention is not only excellent washing power, but also abundant and fine continuous self-foaming can eliminate the irritation caused by skin friction, reduce excessive sebaceous film removal, excellent makeup cleansing gel type It is to provide an aqueous face wash composition.

In order to achieve the above technical problem, the present invention is 5-20% by weight of polyoxyethylene alkyl ether sulfate anionic surfactant, 0.5-20% by weight of amino acid anionic surfactant, 10-30% by weight of volatile oil, Itacco It provides a self-foaming gel-type aqueous cleanser composition, characterized in that it comprises 0.1-1% by weight of the Nate copolymer and the balance of water, more preferably the polyoxyethylene alkyl ether sulfate-based anionic surfactant It provides a self-foaming gel-type aqueous face wash composition characterized in that the sodium laureth sulfate (SLES).

In the present invention, intensive research has been carried out to develop an aqueous cleanser having a self-foaming ability and a gel-sustaining foam, and as a result, an aqueous solution containing SLES, an amino acid-based anionic surfactant, a volatile oil and an itaconate copolymer The present invention has been completed to find that the face wash composition can achieve this purpose.
