Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a peeling cosmetic composition having an appropriate scrub feeling and an excellent feeling upon use. [0002] In general, peeling cosmetics are cosmetics intended to remove waste products and adhered dirt from the skin, and specific methods for removing the waste products are physically waste products. And the like, and a method of chemically dissolving and removing. As a cosmetic using a physical method, there is a cosmetic using an organic powder, an inorganic powder, or a composite thereof and utilizing a frictional action of the powder. For example, those using mineral powder (Japanese Patent Publication No. 60-15680)
JP-A-6-7208), those using vegetable powders of rice, tapioca, etc. (JP-A-61-7208), those using a processed cellulose product (JP-B-5-60446, JP-A-63)
Japanese Unexamined Patent Publication (Kokai) No. 238008/1990) and those using aggregates of short fibers (Japanese Unexamined Patent Publication (Kokai) No. 62-238211) are known. In addition, there is a type using a water-soluble polymer or a powder having high adhesion to waste products of the skin and the like, and utilizing its adsorption action. For example, those using polyvinyl alcohol (Japanese Patent Publication No. 60
No. -50766) is known. As a cosmetic using a chemical method, for example, a cosmetic obtained by dissolving keratin with a salicylic acid derivative (JP-A-62-22624) is known. [0003] The peeling cosmetics containing the above-mentioned powders and the like use a physical scrubbing action or an adsorbing action at the time of use to clean skin waste and dirt, and It is useful because a massage effect such as promotion of blood circulation of the skin can be obtained by utilizing the force applied at that time, and most products manufactured from such a viewpoint have been conventionally used. Processed powders, for example, those using a finer powder, have a high cleaning effect, but have a poor scrubbing effect during use.
In the case of using a short fiber aggregate obtained by treating a short fiber powder with a solid oil or the like, a soft scrubbing action was obtained, but the cleaning effect was somewhat insufficient. Further, those using the water-soluble polymer adsorbing action can provide a sufficient cleaning effect, but have too large an adhesive force to put a heavy burden on the skin, which may cause skin roughness and the like. The method of chemically dissolving keratin also imposes a heavy burden on the skin, and may cause skin irritation when the skin becomes rough or when the skin is damaged. As described above, various studies have been conducted on powders to be blended, but no studies have focused on the particle size, shape, and properties of the powder to study the effects on the skin. [0004] Under these circumstances, the present inventors have conducted intensive studies and as a result, in order to solve the above-mentioned problems, two types of long and short fibrous powders and a method for enhancing the scrubbing action. It has been found that a more excellent peeling cosmetic can be obtained by blending a powder having a specific particle size with a specific amount in a specific ratio, and based on these findings, the present invention has been completed. [0005] That is, the present invention relates to the components (a) to (c)
Component (a) a short fibrous powder having a fiber length of 0.8 to 1.5 mm; Powder (c) contains a powder having an average particle diameter of 0.5 to 1.5 mm, and the blending ratio b / a of the fibrous powder is 0.
5 to 7, and the compounding ratio of the fibrous powder and the granular material (a +
b) / c is 0.5 to 10, and the total amount (a +
b + c) is from 5 to 20% by weight. The short fibrous powder having a fiber length of 0.8 to 1.5 mm, which is the component (a) used in the present invention, is, for example, a cellulose-based, polyester-based, polyamide-based or polyacrylonitrile-based fiber, and more specifically, Include synthetic fibers such as rayon, acetate, nylon, tetron, and acrylic,
Natural fibers such as wool and silk fiber are exemplified. These may be used alone or in combination of two or more as necessary, and those having a thickness of 400 μm or less are preferably used. These short fibrous powders may have any shape such as a needle shape, a rod shape, and a cylindrical shape. Note that these short fibrous powders may be subjected to a surface treatment using a known method. If the fiber length of the short fibrous powder is less than 0.8 mm, the adhesiveness to the skin becomes too high, and considerable force is required when removing the short fibrous powder. In addition, the time becomes longer than necessary. On the other hand, when the fiber length of the short fibrous powder exceeds 1.5 mm, the adhesion to the skin becomes too low, and waste products cannot be sufficiently removed. [0008] The long fibrous powder used as the component (b) in the present invention has a fiber length of 2% of the short fibrous powder of the component (a).
It is twice or more and 5 mm or less. Like the component (a), the long-fibrous powder may be, for example, cellulose-based, polyester-based, polyamide-based, polyacrylonitrile-based fibers, more specifically, synthetic fibers such as rayon, acetate, nylon, tetron, and acrylic. And natural fibers such as wool and silk fiber. These can be used singly or in combination of two or more as needed. The thickness is preferably 400 μm or less, and the length is 5 mm.
It is preferably used below. The component (a) and the component (b)
The components may be homogeneous or heterogeneous, or a mixture of homogeneous and heterogeneous. These long fiber powders are acicular,
The shape thereof does not matter, such as a rod shape and a cylindrical shape. In addition, you may perform surface treatment on these long-fibrous powder using a well-known method. The long fibrous powder is compounded together with the short fibrous powder, and has a synergistic effect when used in combination with a powder having an average particle diameter of 0.5 to 1.5 mm, which is the component (c) described later. Demonstrate. That is, short fibrous powder having high adhesion to the skin, long fibrous powder having low adhesion to the skin, and powder having an excellent scrubbing effect are excellent in the adhesion of short fibrous powder to the skin. With a good cleaning effect and a good scrubbing effect of the granular material, a moderate scrub feeling is brought about. Furthermore, the long fibrous powder having the smoothness of massage and good detachability from the skin gradually removes the short fibrous powder from which waste products are removed from the skin. The fibrous powder and granules gradually collect and are removed as lump together with skin waste and attached dirt.
If the fiber length of the long fibrous powder is at least three times the fiber length of the short fibrous powder, more favorable effects will be exhibited. When the fiber length of the long fibrous powder is less than twice the fiber length of the short fibrous powder, the difference in the adhesion between the short fibrous powder and the long fibrous powder to the skin becomes small, Adhesion to the skin becomes uniform and `` the short fibrous powder from which waste products have been removed gradually by the long fibrous powder having the smoothness of massage and good detachability from the skin, While the long fibrous powder is the core, the short fibrous powder and granules gradually gather and are removed as a lump together with skin wastes and attached dirt. " And the scrubbing effect cannot be obtained smoothly or sufficiently. The powder (g) having an average particle size of 0.5 to 1.5 mm, which is the component (c) used in the present invention, includes nylon powder, polyethylene powder, methyl methacrylate having an average particle size within the above range. Powder, synthetic resin powder such as polystyrene powder, polytetrafluoroethylene powder, silicone powder, etc .; synthetic resin foam hard; sintered synthetic resin; solid wax such as microcrystalline wax;
Walnut shell grains, apricot shell grains, almond coarse grains, peach shell grains,
Grinds of plant leaves, roots, stems, fruits, etc., such as corn cob grains; metals, such as aluminum; inorganic substances, such as clay, diatomaceous earth, and shirasu; inorganic substance foams; inorganic substance sintered bodies; A granulated and formed extender for cosmetics, an inorganic white pigment, an inorganic color pigment, an organic pigment, an organic powder, a pearl agent, and the like. These powders may be subjected to a surface coating treatment. If the average particle size of the powder is less than 0.5 mm, a sufficient scrub feeling cannot be obtained. If the average particle size of the powder exceeds 1.5 mm, the scrubbing feeling becomes too strong, and in some cases, pain may be felt, which is not preferable. The average particle size of the powder is more preferably 0.7
１．０1.0 mm, and a better scrub feeling can be obtained. The mixing ratio b / a of the fibrous powder of the short fibrous powder to the long fibrous powder is from 0.5 to 7. In addition, the fibrous powder compounding ratio b / a is more preferably 1 to 5.
When the fibrous powder compounding ratio b / a is less than 0.5, the ratio of the short fibrous powder is too high, the smoothness is insufficient during use, and a feeling of irritation may be felt during massage. In addition, the adhesiveness to the skin becomes high, and while the long fiber powder is used as a nucleus, the short fiber powder and the granular material gradually gather and are removed as a lump together with skin waste and attached dirt. Will take longer than necessary. If the fibrous powder blending ratio b / a exceeds 7, the ratio of the long fibrous powder is too high, and a lump is formed without a sufficient scrub feeling during use. In the present invention, it is necessary that the compounding ratio (a + b) / c of the fibrous powder and the granular material is 0.5 to 10. Further, the mixing ratio (a + b) / c of the fibrous powder and the granular material is more preferably 1 to 7. When the blending ratio (a + b) / c of the fibrous powder and the granular material is less than 1, the ratio of the granular material becomes large, the scrubbing action becomes too strong, and in some cases, a feeling of irritation may be felt. Is not preferred. When the compounding ratio (a + b) / c of the fibrous powder and the granular material exceeds 10, the ratio of the granular material becomes small and a good scrub feeling cannot be obtained. In the present invention, it is necessary that the total amount (a + b + c) of the fibrous powder and the granular material is 5 to 20% by weight. The total amount (a + b + c) is more preferably 10 to 15% by weight. If the total blending amount (a + b + c) of the fibrous powder and the granular material is less than 5% by weight, good peeling action cannot be obtained. Also,
When the total amount (a + b + c) of the fibrous powder and the granular material exceeds 20% by weight, the elongation is poor and the usability and feeling of use are poor, such as being rough. In the present invention, in addition to the above essential components, lower alcohols such as ethanol, propylene glycol, 1,3
-Humectants such as butylene glycol, glycerin, polyethylene glycol, sorbitol, maltitol, sodium chondroitin sulfate, sodium pyrrolidone carboxylate, and sodium lactate; oils such as liquid paraffin, ester oil and silicone oil; water-soluble polymers; electrolytes; An activator, an ultraviolet absorber, a fragrance, a preservative, and the like can be appropriately blended. The present invention relates to a peeling cosmetic composition comprising a specific amount of a specific ratio of two types of fibrous powders of a long and short length and a powder having a specific particle size, as described above. Available in any form. For example, an emulsion obtained by emulsifying oil and water, a gelled product mainly containing an aqueous or oily gelling agent, an oil,
As a dispersion in water, other liquids or emulsions,
Available. The form of the peeling cosmetic composition of the present invention is more preferably a shaking type of a dispersion type in an emulsion. If the emulsion is of the shaking type, the adhesion of the fibrous powder to the skin when spread on the skin, and the feeling of scrubbing of the granular material on the skin,
It is exhibited in the most desirable form, providing a fresh feeling of use, and a good refreshing feeling after use.
