Abstract
PURPOSE: A reaction initiator and a reaction accelerator are previousy dissolved in water or dispersed and a water-retention agent is combined therewith and finally a metal is added to the mixture to produce a pyrogenic agent for chemical body warmers with lessened fluctuation in the pyrogenic temperature becaue of the high effective contact between the reaction initiators, other agents and the metal.
CONSTITUTION: A reaction initiator and a reaction accelerator (which is preferably water-soluble metal chloride or sulfate, water-soluble organic acid, inorganic acid salt, metal oxide and the like, for example, chloroacetic acid as the reaction initiator and manganese dioxide as the reaction accelerator) are dissolved in water and dispersed and a metal) preferably a metal having a larger ionization tendency than hydrogen such as iron) is mixed therewith to produce the titled pyrogenic agent that generates heat by oxidation of the metal in the presence of water and air.
EFFECT: In the agent of the present invention, the amounts of the reaction initiator and reaction accelerator can be reduced to less than 1/5, thus permitting the reduction in costs.
