足出来るものではなかった。(Prior art) It has been known that in order to improve dry aging skin, a hydrophilic skin moisturizer and an oily skin softener, which provide appropriate moisture and oil content to skin JH, are blended into skin cosmetics. It is being However, skin moisturizers such as glycerin and propylene glycol absorb moisture from the stratum corneum, the outermost layer of the skin, and may actually cause loss of moisture in the skin. In addition, when skin softeners such as liquid paraffin and petrolatum are included in skin cosmetics to the extent that they sufficiently prevent water evaporation from the epidermis, they may inhibit the normal metabolism of the skin and cause discomfort such as stickiness. , was not necessarily satisfactory.

が十分ではなかった。Recently, attempts have been made to incorporate chitosan, a derivative of chitin, into skin cosmetics, but since chitosan is a polymer and only dissolves in acidic aqueous solutions with a pH of 5 or less, it is preferable in terms of skin familiarity and irritation. It wasn't. Furthermore, when the polymeric chitonan was used in combination with the acidic mucopolysaccharide described below, the anions and cations reacted and the polymers aggregated, making it impossible to obtain a cosmetic with a uniform and beautiful appearance. In order to improve these drawbacks of high-molecular chitosan, in recent years JP-A-60-

As seen in the publication, it is used as a moisturizing agent in skin cosmetics, but skin cosmetics containing only acidic mucopolysaccharides only adjust the moisture content on the skin surface, and do not affect the inner skin. It did not reach the level of enhancing the moisture retention function and producing skin beautifying effects.

ない。Furthermore, chitosan exhibits the function of regulating the moisture function inside the skin and enhancing the skin's moisturizing function. The skin cosmetic of the present invention improves dry skin by enhancing the skin's own moisture retention function, or maintains the skin in a healthy state to prevent aging, and provides moisture to the skin (
We have completed the present invention by discovering that it has a beautifying effect that gives softness (smooth feel), elasticity, and luster. In the case of the skin cosmetics of the present invention, there is no need to incorporate large amounts of skin moisturizers and skin softeners as in conventional skin cosmetics (the above-mentioned skin moisturizers and skin softeners), and there is no risk that the normal physiological functions of the skin will be prevented.
