<p>PURPOSE:To allow the easy execution of a deodorization treatment by forming a foaming liquid having a specific compsn. and covering a smell generating source with the having foam-like foam thereof and to allow the control of the sustaining time by adjustment of the compsn., expansion magnification, coating thickness, etc., of the foaming liquid. CONSTITUTION:This deodorization treating agent is constituted by contg. a water-soluble high polymer, a water-dispersible high polymer, a foaming agent, and water. The water-soluble high polymer stabilizes the foamed bubbles in a fine state. High polymers which form high clay with solid contents of low water solubility and have high biodecomposability and low toxicity are selected as the water-soluble high polymer. Representative examples include cellulose derivatives, starches, etc. The water-dispersible high polymer stabilizes the bubbles in a relatively large state and is exemplified by natural rubber latex, epoxy resin, etc. Anionic or nonionic surfactants are used as the foaming agent. A long-term deodorizing effect can be obtd. simply by increasing the ratio of the water-dispersible resin and setting the solid content of the foaming liquid at a slightly high level.</p> |
