PURPOSE:A weak-acidity bath preparation that contains a carbonate and an inorganic acid and keep the pH in the bath to a specific vaue of weak-acidity to dissolve carbon dioxide gas, thus developing enhanced blood flow stimulating effect and causing no chilling after a bath. CONSTITUTION:In a foaming bath preparation containing a carbonate and an acid, as an acid, is used at least one selected from inorganic acids, preferably an inorganic acid or salt which develops acidity when dissolved in water, preferably a solid inorganic acid such as sodium or potassium sulfite, pyrosulfite, acidic hexametaphosphate, boric acid or sulfamic acid. Further, the contents of the carbonate is set to 5-80wt%, preferably 10-50wt%, based on the total composition; the inorganic acid, to 10-80wt%, preferably 15-50wt%; so that the pH of the solution containing 0.01wt% of the preparation shows a pH of 4-7, preferably 6.0-6.7. The resultant preparation has good effect to stimulate blood flow. |
