For example, a cosmetic (Japanese Patent Application Laid-Open No. 57-75909) which utilizes the heat generated by contact of alkylene glycol or the like with water, and a cosmetic which utilizes the heat generated by contact of polyethylene glycol and activated zeolite with water (for example, US Pat. Kaihei 6-10
No. 0411), and a pack or the like which utilizes the fact that calcined gypsum generates heat upon contact with water (JP-A-57-114506, JP-A-60-94905, JP-A-62-30)
No. 704, JP-A-63-54308) and the like.
