BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to cosmetics, and more particularly to cosmetics suitable for cleaning cosmetics.

[0002]

2. Description of the Related Art Cream-like detergents containing potassium fatty acid soap as a main ingredient are widely used as facial cleansers because they have a better foaming property and a better feeling of a foamy foam than solid sodium fatty acid soaps. ing. This is because soap is not applied directly to the face-washing, but is whipped and applied with foam. By washing with such bubbles, it is possible to avoid that the skin of the face, which is a site vulnerable to irritation, receives irritation due to washing. Foam cleaning has been demonstrated to have the effect of efficiently removing dirt at low soap concentrations. However, although the creamy cleaning agent is much easier to foam than the solid soap, the work of foaming the cleaning agent is a laborious task. There are few cases where it is used with the part remaining, and the incidence of troubles that feel irritation due to face washing, which is reflected in this, is higher than other cosmetics, and if you trace each trouble individually, cream It is often the case that cleaning is performed in a form including direct application of the cleaning agent with the cleaning agent remaining in the form, and it has been desired to develop a means for easily foaming the cleaning agent.

On the other hand, as a cleaning cosmetic, a cleaning cosmetic characterized by containing a water-disintegrating porous powder is not known at all, and a cleaning cosmetic having such a structure is known. It has not been known at all that the material has the property that it can be easily foamed, whereby it can be used with extremely avoiding the onset of irritation.

[0004]

The present invention has been carried out under such conditions, and an object of the present invention is to provide a creamy detergent which can be easily foamed.

[0005]

[Means for Solving the Problems] In view of such a situation, the present inventors have made earnest research efforts in search of a creamy detergent that can be easily foamed, and as a result, a water-disintegratable porous powder has been obtained. The present invention has been completed by finding such characteristics in a cosmetic for cleaning, which is characterized by containing That is,
The present invention relates to the technical fields shown below. (1) A cosmetic composition for cleaning, which comprises a water-disintegrating porous powder.

BEST MODE FOR CARRYING OUT THE INVENTION (1) Water-disintegrating porous powder which is an essential component of the cosmetic of the present invention The cosmetic of the present invention is characterized by containing a water-disintegrating porous powder as an essential component. To do. Here, the water-disintegrating porous powder is a powder having a characteristic that its solid structure is disintegrated by water, and is a general term for particles having porous voids inside. In the cosmetic of the present invention,
Disintegration by water itself is something that dissolves in water,
This may be provided with voids, or may be in the form of a powder obtained by binding a water-insoluble fine powder with a water-soluble binder. The preferred one is one which itself dissolves in water and is provided with voids. This is because the residual solid may cause irritation due to friction of the solid during cleaning. Of course, this is not the case in the case of using solid abrasion such as scrubbing. To process a water-insoluble solid into a water-disintegrating porous powder, for example, a bulky powder such as starch, cellulose, chitin, silica or calcium carbonate is added to a water-soluble binder such as carboxymethyl cellulose or hydroxypropyl cellulose. Using the agent, using a granulator such as "Flow coater" (registered trademark, manufactured by Freund Sangyo Co., Ltd.) or "New Marmelizer" (registered trademark, manufactured by Fuji Paudal Co., Ltd.) Just drop it. When a water-disintegrating porous powder is produced from a water-soluble solid, the above water-insoluble solid may be changed to a water-soluble solid and granulated in the same manner. At this time, the binder may or may not be used. As the water-soluble solid used for such production,
One or more selected from sugars such as sucrose, glucose, fructose and maltitol can be preferably exemplified. Such a water-disintegrating porous powder using a water-soluble solid can be produced as described above, but a commercially available powder having such properties can also be used. it can. Preferable examples of such commercially available water-disintegrating porous powder include frost sugar. The water-disintegrating porous powder, which is an essential component of the cosmetic composition for cleaning of the present invention, preferably has a bulk specific gravity of 0.
It may be 01 to 1, and more preferably 0.1 to 0.5. This is because if the bulk specific gravity is too small, the water-disintegrating porous powder may collapse at the time of production, and if it is too large, the effect of imparting easiness of foaming becomes too small. These water-disintegrating porous powders may contain only one kind, or may contain two or more kinds in combination. The preferred content of the water-disintegrating porous powder is 0.1 to 20 with respect to the total amount of the cosmetic.
%, More preferably 1 to 10% by weight. This is because if the amount is too large, the content of the cleaning component may be relatively small and the cleaning property may be impaired, and if it is too small, the effect of imparting easiness of foaming may not be obtained.

(Production Example 1) 90 parts by weight of starch and 10 parts by weight of hydroxypropyl cellulose were placed in a "New Marumerizer", granulated while spraying 30 parts by weight of water, and dried by blowing at 40 ° C for 5 hours. A water-disintegrating porous powder 1 was obtained by sieving and fractionating with a 100-mesh pass and a 200-mesh on. The bulk specific gravity of this product was 0.41.

(Production Example 2) 90 parts by weight of silica gel and 10 parts by weight of hydroxypropyl cellulose were charged into a "New Marumerizer", granulated while spraying 30 parts by weight of water, and dried by blowing at 40 ° C for 5 hours. A water-disintegratable porous powder 2 was obtained by sieving and fractionating with a 100-mesh pass and a 200-mesh on. The bulk specific gravity of this product was 0.64.

(Production Example 3) 90 parts by weight of cellulose and 10 parts by weight of hydroxypropyl cellulose were charged into a "New Malmerizer", granulated while spraying 30 parts by weight of water, and dried by blowing at 40 ° C. for 5 hours. The water-disintegratable porous powder 3 was obtained by sieving and fractionating with 20 mesh and 100 mesh. The bulk specific gravity of this product was 0.27.

(2) Cleaning Cosmetic of the Present Invention The cleaning cosmetic of the present invention is characterized by containing the water-disintegrating porous powder as an essential component. If the cleaning cosmetic of the present invention is a cosmetic used for cleaning,
It can be applied without particular limitation, but in view of the shape-maintaining property of the water-disintegrating porous powder, it is preferably in the form of paste or cream. Therefore, it is preferable to use fatty acid potassium soap, which is generally used in such a dosage form, as the main washing component. The cleansing cosmetic composition of the present invention may contain any of the components commonly used in cleansing cosmetic compositions. It may contain optional ingredients commonly used in detergents. Such optional components include, for example, hydrocarbons such as squalane, petrolatum and microcrystalline wax, silicones such as dimethicone and femethicone, cross-linked methyl polysiloxane, jojoba oil, bezel wax, carnauba wax, olein. Esters such as octyldodecyl acid, triglycerides such as olive oil, beef tallow, and coconut oil, stearic acid, oleic acid,
Fatty acids such as lithinoleic acid, oleyl alcohol, stearyl alcohol, higher alcohols such as octyldodecanol, polyethylene glycol, glycerin, 1,3
-Polyhydric alcohols other than polyoxyethylene polyoxypropylene glyceryl ether such as butanediol, sorbitol, maltitol, fatty acid monoglycerides,
Nonionic surfactants such as sorbitan fatty acid ester, polyoxyethylene sorbitan fatty acid ester, polyoxyethylene fatty acid ester, polyoxyethylene alkyl ether, thickening / gelling agents, antioxidants, ultraviolet absorbers, organic dyes, etc. Colorants, preservatives, titanium dioxide,
Examples thereof include powders of iron oxide, titanium mica, colored titanium mica, iris foil and the like. Particularly preferred among these are the cosurfactants polyoxyethylene fatty acid glyceryl, polyoxyethylene (8)
Coconut oil fatty acid glyceryl, polyoxyethylene (8)
(Capric acid / caprylic acid) glyceryl and the like can be particularly preferably exemplified. These surfactants are excellent in removing oil stains without impairing foaming. Such polyoxyethylene fatty acid glyceryl may contain only one kind, or may contain two or more kinds in combination. The total content of these polyoxyethylene fatty acid glyceryl is preferably 0.1 to 10% by weight, more preferably 0.5 to 5% by weight, based on the total amount of the cosmetic ingredients other than foam. Cosmetics other than foam can be produced by treating these optional components and a water-disintegrating porous powder which is an essential component according to a conventional method. The thus-obtained cleansing cosmetic composition of the present invention can be easily foamed by anyone and used, and thus is suitable as a face wash which is said to cause a lot of irritation due to residual detergent. This is because the amount of residual detergent can be reduced and irritation can be prevented by using the cleansing cosmetic composition of the present invention as a face wash.
