PURPOSE:To obtain a foamable composition having high storability and soluble rapidly in water generating carbon dioxide gas bubbles, by contacting carbon dioxide gas with a water-soluble carbonate, bicarbonate, or with a mixture containing both salts and an organic acid solid at normal temperature, and molding the reaction product. CONSTITUTION:A water-soluble carbonate, bicarbonate, or a mixture containing both salts and an organic acid which is solid at normal temperature is made to contact with carbon dioxide gas, and the product is molded to obtain the objective foamable composition. The carbonate and bicarbonate are sodium or potassium salt, and the organic acid is tartaric acid, oxalic acid, citric acid, succinic acid, malic acid or their mixture. |
