Description

  The present invention relates to a cleansing material, and more particularly, to a cleansing material that has a novel appearance, is excellent in the effect of smoothly removing dirt such as makeup and sebum, has a good feeling of use, and has a good stability. .

  Makeup cosmetics applied to the skin and cleansing materials used to remove sebum have various dosage forms such as emulsification type and oily type, and various forms from liquid to solid. You can enjoy various feelings of use corresponding to. Among these, the one that can enjoy its appearance and aesthetics is a two-layer type that has different layers of an aqueous component and an oily component and is used by shaking at the time of use (for example, see Patent Document 1) There are a two-layer type in which powder is mixed with an aqueous component, a type in which a scrub agent is blended (for example, see Patent Document 2), and the like.

  Of these, those containing a scrub agent not only enjoy the appearance but also have a stronger cleansing effect, and at the same time a massage effect such as promoting blood circulation and activating metabolism is added. Has been developed. For example, a combination of a scrub agent and a fiber (for example, see Patent Document 3), a combination of fibers having different lengths to obtain a scrub action (for example, see Patent Document 4), and the like have been reported.

  On the other hand, as a technique for enjoying the aesthetics of the appearance using fibers, cosmetics (for example, see Patent Document 5) that impart a high-saturation cosmetic film to the use site using colored fibers are known.

  However, although conventional scrubbing agents and cleansing materials containing fibers are excellent cleansing materials in terms of efficiently removing dirt, fiber blending has been considered a negative factor in terms of aesthetic appearance. This is because fibers such as nylon that have been used in conventional cosmetics exhibit a clear to white color, and when blended into a cosmetic dosage form that is transparent in appearance, the color saturation is low and the appearance with high saturation is sufficient. This is because it could not be granted.

  Therefore, by coloring the fiber with a dye or the like, a cosmetic having a high-saturation cosmetic film can be obtained, but in the emulsifier type such as O / W and W / O, the fiber itself becomes cloudy because the system becomes cloudy. It was difficult to see, and it was impossible to impart high saturation and glitter to the appearance of the cosmetic.

JP-A-8-99836 JP 2001-322914 A Japanese Patent Laid-Open No. 9-20647 Japanese Patent No. 3378972 JP 2000-319132 A

  Accordingly, there is a need for a cleansing composition that can efficiently remove makeup cosmetics and dirt such as sebum, has good usability and stability, and has a beautiful appearance. The provision of a fee is the subject.

  As a result of diligent research to solve the above-mentioned problems, the present inventor only has an excellent effect of removing makeup, sebum, and the like by combining a specific fiber with a liquid oil and / or surfactant that is liquid at room temperature. In addition, the present inventors have found that a cleansing material having a high appearance, excellent chromatility, and a new texture can be obtained.

That is, the present invention includes the following components (A) to (B);
(A) Colored interference fiber containing two or more kinds of polymer compounds having different refractive indexes (B) A cleansing material characterized by containing an oil agent and / or a surfactant that is liquid at room temperature.

  The cleansing material of the present invention has high chroma and volatility in its appearance without impairing the original effects of the cleansing material such as usability, usability, and dirt removal effect.

  At least two types of interference fibers (hereinafter abbreviated as “colored interference fibers”) containing two or more kinds of polymer compounds having different refractive indexes, which are colored in the component (A), used in the cleansing material of the present invention. It is a fiber obtained by coloring a composite fiber having a layered cross-sectional structure (laminated cross section) composed of the above polymer compounds with a colorant, and this composite fiber has interference colors such as red, yellow, green, blue, purple, etc. It presents. As for the cross-sectional shape, a flat cross-section interference fiber in which a parallel laminated portion is sandwiched by a protective layer is also desirable in order to make color development from one direction stronger. The polymer compound used in the colored interference fiber is not particularly limited as long as it is usually used in cosmetics. Examples thereof include nylon, polyethylene terephthalate, polypropylene, polycarbonate, polymethyl methacrylate, and polyester. . Among these polymer compounds, a combination of polyethylene terephthalate and nylon is preferable because it strongly exhibits interference light and has good fiber process stability, and the effects of the present invention appear more remarkably.

  As a coloring agent used for manufacture of the component (A) of this invention, if normally used for cosmetics, it will not restrict | limit, Any thing can be used. For example, Red No. 2, Red No. 3, Red No. 102, Red No. 104 (1), Red No. 105 (1), Red No. 106, Yellow No. 4, Yellow No. 5, Green No. 3, Blue No. 1 as colorants , Blue No. 2, Red No. 201, Red No. 213, Red No. 214, Red No. 215, Red No. 227, Red No. 230 (1), Red No. 230 (2), Red No. 231, Red No. 232, Orange No. 205 Orange No. 207, Yellow No. 203, Green No. 201, Green No. 204, Green No. 205, Blue No. 202, Blue No. 203, Blue No. 205, Brown No. 201, Red No. 401, Red No. 502, Red No. 503, Red 504, red 506, orange 402, yellow 402, yellow 403 (1), yellow 406, yellow 407, green 401, green 402, purple 401, black 401, etc. Tar dye, red 02, Red 218, Red 223, Red 226, Red 228, Orange 201, Yellow 201, Yellow 205, Blue 201, Blue 204, Purple 201, Red 404, Red 405 , Orange 401, Yellow 401, Yellow 404, Yellow 405, Blue 403, Blue 404, etc. Water-insoluble tar dye, gardenia dye, safflower dye, turmeric dye, paprika dye, anato dye, cochineal dye Natural pigments such as acidic pigments, basic pigments, and disperse dyes. Among these, water-soluble tar pigments are most preferable in terms of obtaining colorability, stability, and a remarkable cosmetic effect. Moreover, these colorants can use 1 type (s) or 2 or more types, and can provide a various color tone to a component (A).

  The amount of the colorant used for coloring the interference fibers is not particularly limited and is determined according to the purpose, but is 0.01 to 30% by mass (hereinafter simply referred to as “%”) of the entire colored interference fibers. Preferably, 0.01 to 10% is more preferable. If it is in this range, a visual effect such as imparting aesthetics to the appearance of the cleansing material can be sufficiently obtained together with the cleansing effect. Further, if the color of the colorant is similar to the interference color, it is effective because it does not hinder the wavelength necessary for optical interference from reaching the laminated portion. When colored with the color opposite to the interference color, the colorant absorbs the wavelength that exhibits the interference effect, and the color development of the interference fiber may decrease. For this reason, it is preferable to color the interference fiber with a color that is similar to or not complementary to the color of the interference fiber, because the interference light is strongly exhibited and the effects of the present invention appear more remarkably. Here, the similar color means a hue that is adjacent on the 24-color ring table of the P.C.C.S. color system. For example, when the interference color is red, reddish purple to orange are similar. Color. Further, when the interference color is yellow, orange to yellow-green is used. When the interference color is green, yellow green to blue is used. When the interference color is purple, blue to purple is used.
