PURPOSE:To prevent trouble, e.g. capping or sticking phenomenon, in tableting without inhibiting the performance of a bath tablet, by using adipic acid and/or alkali metal salt thereof as a lubricant in tableting a foaming bath agent. CONSTITUTION:A foaming bath agent is tableted by using at least one of adipic acid and alkali metal salts thereof as a lubricant using, e.g. the following methods; A raw material mixture containing an organic acid, e.g. citric acid, and an inorganic acid salt, e.g. sodium carbonate, as a foaming principal components is first formed into granules having preferably about 32-100 mesh grain size in a dry granulating machine, and, as necessary, further sorting and grading the granules. About 1-10wt%, preferably 3-6wt% of the above- mentioned lubricant is then added and uniformly mixed with the granules and the resultant mixture is tableted according to the conventional method to give the aimed foaming bath agent. According to this method, the above-mentioned trouble can be prevented in tableting without inhibiting the performance by the lubricant. |
