Abstract
The present invention aims to provide a warming composition showing a favorable dispersion stability after long-term storage, a high warming impact, and improvement of zeolite-specific deterioration of feeling of use, and to provide an aerosol formulation containing the warming composition. This object is achieved with a warming composition containing zeolite nanoparticles having an average particle size of not more than 500 nm, wherein the temperature of the composition is rapidly increased by heat generated by hydration reaction between the zeolite and water.
