PURPOSE:To obtain the titled composition which has only little change in pH and has fluidity and self-adhesive properties and is not self-adhesive for skin or the like and available as a poultice by using a buffer soln. having pH of the specified region as a solvent for a specified polysaccharide, sodium tetraborate and polyvalent alcohol. CONSTITUTION:An alkali buffer soln. having 7-11pH is incorporated in polysaccharide having OH group in cis-position such as rocast beam gum, sodium tetraborate and polyvalent alcohol such as ethyleneglycol and sorbitol. As the aimed composition obtained in such a way, the change in pH is suppressed and the adhesive properties are not shown when it is touched to skin. As the buffer soln., potassium dihydrogenphosphate and disodium hydrogenphosphate are preferable. 0.1-10pts.wt. polysaccharide, 0.01-5pts.wt. sodium tetraborate and 0.1-40pts.wt. polyvalent alcohol are desirable for 100pts.wt. titled composition. Furthermore the aimed composition is used as a poultice or the like.
