DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration of the present invention will be described below in detail.

The dextrin used in the present invention refers to an intermediate product from hydrolysis of starch to maltose, and is represented by (C ₆ H ₁₀ O ₅ ) n × x H ₂ O. It is obtained by treating with acid, heat and the like.

There are various types of dextrins depending on the method of hydrolysis, for example, soluble starch, thin nori starch, amylodextrin, white dextrin, yellow dextrin, British gum, erythrodextrin, acrodextrin and the like. One or two or more types can be selected and used. For example,
A crude dextrin obtained by heating, acid-hydrolyzing, or diastase-hydrolyzing starch, dissolved in water, precipitated with alcohol, and purified using a mixture of various water-soluble molecular weights can be used, and commercially available products can be used.

The amount of the dextrin in the pack cosmetic is preferably 0.5 to 25% by weight based on the total amount of the pack cosmetic.
More preferably 3.0 to 20% by weight, most preferably 1 to 20% by weight.
0 to 15% by weight. If the amount is less than 0.5% by weight, it may not be possible to obtain sufficient skin tension, adhesion and beaming effect, and if it exceeds 25% by weight, it gels with time or discolors at high temperatures. A problem may occur in the stability.

It is preferable that the pack cosmetic of the present invention further contains a polymer compound together with the above essential components. When a high molecular compound is used in combination, the effects of tension, adhesion and affixing to the skin can be further enhanced, and the viscosity of the pack cosmetic can be increased to facilitate application. further,
There is also an effect of exhibiting a keratotic plug removal effect.

The polymer compound used in the present invention is a compound which can be added to a pack cosmetic as an emulsion polymer or a water-soluble polymer. As the emulsion polymer, polyvinyl acetate and polyethyl acrylate are preferable. Examples of the water-soluble polymer include polyvinyl alcohol, polyvinylpyrrolidone, polyvinyl methyl ether, alkanolamine polyacrylate, vinylpyrrolidone / vinyl acetate copolymer, gum arabic, gelatin, methylcellulose, ethylcellulose, hydroxyethylcellulose, sodium carboxymethylcellulose,
Preferred are sodium alginate, alkyl methacrylate / dimethylaminoethyl methacrylate copolymer, polymethacryloyloxytrimethylammonium, and poly-2-acrylamido-2-methylpropanesulfonic acid. In particular, polyvinyl acetate, polyethyl acrylate, polyvinyl pyrrolidone, polyvinyl methyl ether, polyalkanolamine polyacrylate, and vinyl pyrrolidone. It is a vinyl acetate copolymer.

One or more of these polymer compounds can be selected and blended, and the blending amount is preferably 0.1 to 10% by weight based on the total amount of the pack cosmetic.

It is preferable that the pack cosmetic of the present invention further contains an alcohol in addition to the above essential components. The combined use of alcohol can further enhance the feeling of tension and adhesion to the skin, and has the effect of speeding up drying after applying the pack cosmetic.

The alcohol used in the present invention is a lower alcohol, preferably ethanol or isopropanol, and the compounding amount thereof is preferably 1 to 30% by weight based on the total amount of the pack cosmetic.

It is preferable that the pack cosmetic of the present invention further contains a powder together with the above essential components.
