PURPOSE:A weak-acidity bath preparation having raised promoting effect on circulation of the blood, not causing a chill after a bath, comprising a carbonate and an organic acid, adjusting pH to a specific value (weakly acidic) when it is dissolved in hot water in a bath so that a carbonic acid gas is dissolved in it. CONSTITUTION:In a foaming bath preparation comprising a carbonate and an acid, an organic acid, preferably 1-6C short-chain aliphatic carboxylic acid, oxyacid, acidic amino acid, aromatic carboxylic acid, its acidic salt, nicotinic acid, kainic acid, sorbic acid, benzenesulfonic acid, toluenesulfonic acid and/or pyrrolidonecarboxylic acid is used as the acid. 5-80wt%, especially 10-50wt% carbonate is blended with 10-80wt%, especially 15-50wt% organic acid so that 0.01wt% aqueous solution obtained by dissolving the bath preparation in hot water in a bath is adjusted to 4-7, especially 6.0-7.0, to give the weak acidity bath preparation having extremely improved promoting effect in blood circulation. |
