Description

  The present invention relates to a cleansing composition that removes makeup such as foundation, lipstick, and eye makeup. More specifically, it has an appropriate viscosity, has a high makeup removing ability, and has a fresh and refreshing feeling of use. The present invention relates to a cleansing composition having excellent stability.

  In recent years, a variety of types have been developed, from simple and light makeup that makes the most of the skin, to hard makeup that resists sweat and sebum, with the evolution of makeup technology. Furthermore, as women advance into society and their lifestyles diversify, not only make-up removal ability, but also emphasis on ease of use such as cleansing and facial cleansing with one product, skin care effects and feeling of use. Variations of cleansing cosmetics, such as types that emphasize added value, etc. are also expanding.

On the other hand, cleansing compositions can be classified into three types: aqueous, emulsified, and oily when technically classified.
Aqueous type cleansing compositions are mainly composed of aqueous components, with a small amount of surfactants and oils dissolved to remove makeup stains. It is easy to wipe off. Conventionally, surfactants and various additive components have been studied. For example, Patent Document 1 contains polyoxyethylene fatty acid glyceryl and diethoxyethyl succinate, has no irritation to the ocular mucosa, and has no makeup. A water-based cleansing composition that easily removes oil and fat stains and the like and suppresses stickiness after wiping is described.

  The emulsifying type cleansing composition is obtained by emulsifying an oil agent using a surfactant, and has a feature that it has a higher make-up removing ability than an aqueous type and can realize various feelings of use. For example, Patent Document 2 contains an oil-in-water emulsion-in-water emulsified skin cleanser that contains an oil, polyoxyethylene monofatty acid glyceryl, water, and a thickener, has a fast make-up, excellent emulsification stability, and is easy to wash away. Fees are listed.

  The oily type cleansing composition has a high makeup removing ability due to the solvent effect of a large amount of oil, and is also suitable for cleansing hard makeup such as a waterproof type. For example, in Patent Document 3, two specific types of polyglycerin fatty acid esters are used in combination, and a liquid ester oil composed of monohydric alcohol and fatty acid at 25 ° C. is combined with an excellent cleansing effect, feeling of application and use. An oily liquid cleansing cosmetic with a good later feel is described.

However, the water-based cleansing composition is limited to light makeup cleansing applications because it does not have the ability to remove make-up to remove hard makeup sufficiently. In addition, if an oil agent or a low-polarity surfactant is contained in order to enhance the makeup removing ability, there may be a problem in stability.
In addition, the emulsifying type cleansing composition may have a bad makeup fit, or an oil film may remain and the feeling after use may be impaired.
Since the oil-based cleansing composition depends on the oil agent contained in the oily composition, the oily type cleansing composition tends to sag during use, and an oily stickiness may remain after use.
As described above, in the cleansing composition, there is a problem of compatibility between make-up removal ability and good feeling of use, and since there is nothing that satisfies all, the user can make up the makeup from the various types described above. The actual situation was to select according to the type and the feeling of use.

  In view of such circumstances, an object of the present invention is to provide a cleansing composition having a fresh and refreshing feeling of use and excellent stability while having a high makeup removing ability capable of removing hard makeup stains. . Furthermore, the present invention is intended to provide a cleansing composition that has a viscosity suitable for use during cleansing and that satisfies the feeling of good skin with less stickiness when used after washing.

  As a result of intensive studies, the present inventors have found that among various surfactants, fatty acid alkanolamides are excellent in makeup removing ability. Furthermore, considering the usability, the addition of various water-soluble polymers was studied for the purpose of imparting an appropriate viscosity. As a result, it was found that nonionic cellulose derivatives are preferable because they have less stickiness on the skin after use. . Among them, it has been found that those having an alkyl group and / or an alkyl-oxyalkylene group containing a hydroxyl group per se have good compatibility with makeup stains and synergistically improve makeup removal ability. Therefore, further investigation was carried out using fatty acid alkanolamide and nonionic cellulose derivative as essential components. As a result, the two components and a specific alcohol were combined, and an anionic surfactant was contained in a specific ratio with respect to the fatty acid alkanolamide. Then, it discovered that the remarkable thickening effect was acquired. In the present composition, the viscosity is also important in terms of removing the makeup dirt from the skin and removing it from the skin, and the present invention was completed by further studying the relationship between the content of each component and the thickening effect. .

  Further, the present invention relates to a cleansing composition in which the component (C) is one or more selected from ethanol, propylene glycol, dipropylene glycol, 1,3-butylene glycol, 1,2-pentanediol, glycerin, and diglycerin. .

  Furthermore, the present invention relates to a cleansing composition in which the hydrogen atom of the hydroxyl group of cellulose in the component (B) is substituted with an alkyl group containing a hydroxyl group and / or an alkyl-oxyalkylene group containing a hydroxyl group.

  Furthermore, it is related with the cleansing composition whose said component (B) is 1 type (s) or 2 or more types chosen from hydroxypropyl methylcellulose (HPMC), hydroxyethylcellulose (HEC), methylhydroxyethylcellulose (MEHEC), and ethylhydroxyethylcellulose (EHEC). .
