摘要

PROBLEM TO BE SOLVED: To provide a deodorization method and to obtain a deodorizer which can safely block an odor from various kinds of malodor substance storage tanks for a long period of time at a low cost. SOLUTION: An aerosol composition of a foaming agent contains 10 to 20 wt.% of a propellant, 20 to 30 wt.% of a surfactant, 1 to 10 wt.% of a deodorizing agent and 55 to 65 wt.% of water. Then, such an aerosol composition is jetted into a malodor substance storage tank from a pressure container for jetting. The surface of a malodor substance is covered with a foamed shielding film.
