Sustained Modulation of Temperature of Self Heating Chemical System

Exothermic reactions are used in self heating products, such as food, beverages, and clothing. Temperature peaks are important as heat can cause user injuries or increase pressures within the heating container to unsafe levels. Disclosed is a composition that modulates chemical reactions by control of the reaction initiation. Solid exothermic reactants, like calcium oxide and zeolite, are wetted with a combination of water and at least one surfactant, such as polyethylene glycol. The use of surfactants limits the initial rate of wetting, and also provides modulation of the reaction by changing phase. Optional addition of weak acids or acid salts modulated temperature and pH.
