<p>PURPOSE:The titled safe, easily producible and inexpensive composition free from evolution of a hydrogen gas during storage, useful as a disposal body warmer releasing heat in the presence of air, containing active carbon produced as a by-product in reduction of ion ore as a water-retaining agent, a metal and a reaction auxiliary. CONSTITUTION:(A) A metal is blended with (B) a reaction auxiliary, and (C) active carbon produced as a by-product as a water-retaining agent, to give the aimed composition. The particle diameter of the active carbon is larger than 150 meshes, preferably 80-30 meshes substantially and the amount of the component B is 10-40pts.wt. based on 100pts.wt. component A.</p> |
