Abstract
Abstract The present invention relates to a cosmetic comprising a neutral polysaccharide obtained from an acid-fast bacterium. This cosmetic smoothly spreads on the skin without sticking to the skin to give moistness to the skin. Furthermore, the cosmetic covers the skin and shows an excellent moisture-retaining action, and exerts an effect of preventing or moderating the rough skin.
