Abstract: The present invention provides an exothermic body for use of an insole of shoes and so forth with elasticity, softness and flexibility, the exothermic heat of which is distributed uniformly along the entire area thereof. The exothermic body includes a foamed plastic sheet having cells therein, the cells being filled with an exothermic agent such as a mixture of iron, saline solution, activated carbon and woodmeal or pulp powder. The foamed plastic sheet is covered by an air-permeable thin film such as a thin perforated plastic film. A cushion material is provided on at least one surface of the foamed plastic sheet covered with the air-permeable thin film and the foamed plastic sheet together with the cushion material is covered by an air-permeable film cover.

Abstract: A process for the preparation of granules containing a high concentration of a viscous substance, which granules are free-flowing and are not likely to cake or agglomerate under normal storage conditions, characterized by the steps of incorporating in a viscous substance selected from the group consisting of higher alcohols having 8 to 18 carbon atoms and which are soft or molten or liquid at a temperature lower than 40.degree. C., and non-ionic surfactants having the formulae (I) and (II): ##STR1## andR.sub.2 --O--(CH.sub.2 CH.sub.2 O).sub.m H (II)wherein R.sub.1 is alkyl having 4 to 18 carbon atoms, R.sub.
