Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economics Technical Field The present invention relates to a skin granulated material, Gan, λ ^ ^ Stomach 1c, which can continue to supply cuticle water after a long period of time. Background Art-Generally speaking, the moisture content in the stratum corneum is important in terms of imparting moisturization to the skin and maintaining softness. In the past, although a cosmetic material containing a moisturizing ingredient was used, its function can only temporarily supply moisture to the stratum corneum of the skin, and it may not be sufficient in terms of sustainability. An object of the present invention is to provide a skin cosmetic material capable of continuously supplying water to the stratum corneum. DISCLOSURE OF THE INVENTION The inventors of the present invention have found that when a specific water-soluble polymer is used in combination, the skin cosmetic obtained can continue to supply water to the stratum corneum even after a long period of time. That is, the present invention provides a skin cosmetic comprising an acrylic polymer, (B) polysaccharides other than mucopolysaccharides, and (c) water. This cosmetic material can continue to supply moisture to the stratum corneum over a long period of time. The best form for carrying out the invention The component (A) acrylic polymer used in the present invention may be a water-soluble polymer using acrylic acid and its salts, acrylates, ammonium acrylate, etc. as structural units, such as polypropylene Acid, Polyacrylamide, Polyacrylamide, Polyacrylamide, Polyethylene Glycol, Acrylic Polymer, Acrylic Acid Methacrylic Acid, Tiger Acrylic Acid Copolymer, Ethyl Propionate, Acrylic Acid Amine · propionic acid copolymer, ethyl propionate · ethyl methacrylate copolymer, butyl acrylate · fluorenyl acrylate This paper size is applicable to China National Standard (CNS) A4 (210 X 297 mm)- I I--Γ II hi II -------- Order --------- Line f Please read the phonetic on the back first?
