PROBLEM TO BE SOLVED: To provide a method for producing bath agents such as a carbonated-spring bath agent, the method effectively and intensively causes a neutralization reaction in the agent despite the fact that the pH of the aqueous solution in which the agent melts becomes neutral in order to generate bubbles, as small as possible, of carbon dioxide gas for a consecutive specific time so as to make the most of the generated carbon dioxide gas dissolved in the water without allowing its escape in the air, thus the method makes the concentration of total carbon acid component in the water become high so that the carbon dioxide gas in touch with human skin easily becomes bicarbonate ions to be absorbed through the skin due to the pH of the aqueous solution, and to provide an agent produced by the method.SOLUTION: There is provided a method for producing an agent by compression molding, the method performing compression molding of bicarbonate (sodium hydrogen carbonate or potassium hydrogen carbonate), organic acid of 1/10 to 1/3 of the bicarbonate, and polyethylene glycol of 1/100 to 1/5 of the bicarbonate, wherein pH of an aqueous solution in which the agent was melted is 5.5 to 8.5, the rigidity of the agent is 15 kg or more, and the diameter direction and thickness direction are each 7 mm or more. |
