PURPOSE:To provide the titled bathing agent storable stably for a long period without using a stabilizer, and dissolving in water while rising and falling is water, by forming an organic acid and a carbonate in separate tablets, putting the tablets in a water- resistant synthetic resin bag having perforations, and sealing the bag in a moisture- resistant synthetic resin bag. CONSTITUTION:A tablet composed mainly of an organic acid such as succinic acid, citric acid anhydride, tartaric acid, etc., and a tablet composed mainly of a carbonate such as sodium bicarbonate, sodium carbonate, sodium sesquicarbonate, etc., are put into a perforated heat-resistant synthetic resin bag (preferably having about 100 holes of 300-400mu diameter per 1cm<2>), and the bag is further packaged and sealed in a moisture-resistant synthetic resin bag. The water-resistant bag is taken out of the moisture-resistant bag in use and thrown into bath. The organic acid is dissolved in hot water entering into the bag through the perforations to increase the acid concentration in the bag to the level sufficient for the reaction with the carbonate. Carbon dioxide gas is generated in the bag by this process. The bag rises according to the generation of carbon dioxide gas until the top end of the bag is exposed from the water surface into air, when the carbon dioxide gas is released to the atmosphere and the bag sinks in water. The bag moves up and down by this mechanism to discharge carbon dioxide gas in bath water. |
