PURPOSE:To obtain the deodorizing liquid composition which is neutral and does not harm a living body so as to be safe even when the compsn. is absorbed in the human body by adding an acid to an aq. soln. of bicarbonate of soda or the carbonate of an alkaline metal to adjust its pH to 5 to 8. CONSTITUTION:An alkali hydroxide is added to the aq. soln. of at least one phosphoric acid selected from a group including orthophosphoric acid, pyrophosphoric acid, polyphosphoric acid, and phytic acid to adjust its pH to 4 to 7. The bicarbonate of soda or the carbonate of the alkaline metal is added to this aq. soln., by which the desired deodorizing liquid compsn. adjusted in pH to 6 to 8 is obtd. Hydrochloric acid, phosphoric acids, etc., are preferable as the acid. |
