Further, the bentonite can be constituted so as to be directly subjected to an acid treatment with an acid.

For example, bentonite classified using a 200 mesh sieve was dried at 110 ° C for 24 hours and reacted with 30%, 40%, and 50% sulfuric acid solution to prepare a 20% slurry, put in a three-necked flask, Acid treatment. The acid-treated bentonite can be filtered to separate and collect the waste acid, and then washed with 5 liters of distilled water at 80 ° C for 5 times and dried at 110 ° C for 24 hours to prepare an acid-treated bentonite. Can be used in the preparation of the fill-off pack composition.

The pack composition may further comprise polyvinyl alcohol, polyvinylpyrrolidone and modified rice starch.

In the pack composition, the polyvinyl alcohol forms a thin coating to smoothly and smoothly cover the skin and hair, and has the effect of controlling the viscosity with the water-soluble thickener.

When the content exceeds 15% by weight, It may be constituted to include 5 to 15% by weight, more preferably 5 to 7% by weight.

The above-mentioned polyvinylpyrrolidone is a raw material having a specific action called toxicity, lowering of irritation and pharmacological system action which can not be found in other cosmetic raw materials, and is used as a raw material for the purpose of lowering irritation, controlling humidity of a film, protecting colloid action, So that the composition can be incorporated into the composition.

By weight, preferably 2 to 15% by weight, and more preferably 2 to 5% by weight.

Modified rice starch in the pack composition makes the rice starch gel into a colloidal state and then evaporates water to form an α-starch network structure. It forms a viscosity through hydration and forms a film to reduce the amount of synthetic polymer And can be configured to be included in the composition.

If the modified rice starch is contained in an amount of less than 0.5% by weight, the content thereof is too small to affect the tensile strength, drying speed or appearance of the pack, and if it exceeds 5% by weight, the viscosity is excessively increased There may be a problem that it is difficult to be sufficiently applied to the skin of the human body. Therefore, it may be composed preferably in an amount of 0.5 to 5% by weight, more preferably 0.5 to 3% by weight.

The pack composition may further comprise clofenesin, butylene glycol, glycerin, ethanol and phenoxyethanol.

In the pack composition, chlorphenesin may be included in the composition because it has the effect of inhibiting the propagation of fungi and preventing the deterioration of the product, which is a sterilizing preservative.
