PURPOSE:The titled bath preparation that is obtained by adding an anticorrosive agen such as sodium tripolyphosphate to a bath preparation which contains a carbonate and an acid and shows weak acidicy in the bath, thus preventing the bothtub and boiler from developing rusts without any adverse effect on the characteristic effect on skins. CONSTITUTION:The objective weak-acidity bath preparation is obtained by adding 0.05-10%, preferably 0.1-5%, based on the total composition, of an anticorrosive agent, preferably a phosphate salt, silicate salt or fatty acid to a weak-acidity bath preparation containing a carbonate salt such as sodium carbonate or potassium carbonate and an acid such as succinic, fumaric or phosphoric acid. The preparation develops a pH almost equal to that of human skins to exert good effect on skin, further carbon dioxide is present in the molecular form to stimulate blood flow. |
