Generally, packs have been used for a long time as major cosmetics to keep skin healthy and beautiful through moisturizing action to moisturize and maintain skin, purifying action to adsorb and remove skin contaminants, and promoting blood purification. These pack cosmetics can be used for topical or whole body as well as face, neck, shoulders, arms, legs, etc. Peel-off-type, cream, clay Tissue-off-type and wash-off-type used for phase, jelly phase, aerosol, peeling-type peeling after solidification, nonwoven gel, non-woven fabric impregnated coating type, etc. It is manufactured variously. Since each of them has advantages and disadvantages, the formulating researchers compensate for their shortcomings by selecting the appropriate type of formulation according to various consumer preferences.

Most pack cosmetics, except non-woven coatings, cover the face temporarily to block external air inflow or evaporation of water.They are polyvinyl alcohol, polyvinylpyrrolidone, hydroxyethyl cellulose, and carboxymethyl. Polymer compounds such as cellulose, vinyl acetate emulsion, xanthan gum and carboxyvinyl polymer are used. However, these pack cosmetics are difficult to wash off after drying as a poorly soluble substance, and when peeling, there is a problem that skin irritation is concerned due to physical irritation.

In addition, the skin moisturizing function of the cosmetic is a basic function that the cosmetics should have, for this purpose has been used to increase the moisturizing ability in the pack cosmetic composition. However, when the moisturizing agent is used to increase the moisturizing ability, a large amount of the moisturizing agent should be used, and the coating is not properly formed when the skin is applied, thereby decreasing the adhesion and adhesion.

Therefore, the development of a new type of pack cosmetics, which enhances the application and adhesion of various types of pack cosmetics, can be easily washed off with water, reduces physical irritation and irritation to the skin, and at the same time increases the moisturizing effect. It is necessary.
