Description

technical field [0001] The present invention relates to a composition containing acidic mucopolysaccharides, which is a composition for external use in which properties of acidic mucopolysaccharides are kept stable. Background technique [0002] Dryness, itching, rashes, ulcers, prickly heat caused by various factors such as skin exposure to ultraviolet rays, extrinsic factors such as changes in temperature and humidity, and intrinsic factors such as aging, which reduce moisture retention or skin barrier function And other troubles. In order to improve these symptoms, the first thing to do is to eliminate the cause, but it is effective to normalize the moisture retention function and skin barrier function by applying pharmaceuticals and cosmetics containing moisturizing ingredients. [0003] As the compound having a moisturizing effect, mucopolysaccharides such as hyaluronic acid, chondroitin sulfate, heparin, dermatan sulfate, heparan sulfate, and keratan sulfate are used....
