<P>PROBLEM TO BE SOLVED: To provide an exothermic composition which keeps a feeling of warm and besides has not a skin stimulation but a safeness against the human body. <P>SOLUTION: This exothermic composition contains polyethylene glycol with an average molecular weight of less than 350, polyethylene glycol with an average molecular weight of not less than 350, and a heat building-up agent. The heat building-up agent is selected from the organic compounds or inorganic compounds having an enthalpy of dissolution into water at 25°C of a negative value, preferably (-10 kJmol<SP>-1</SP>) or less, and specifically is preferably, for example, magnesium sulfate, calcium chloride, and magnesium chloride. <P>COPYRIGHT: (C)2011,JPO&INPIT |
