MITE-EXTERMINATING AQUEOUS LIQUID COMPOSITION AND MITE EXTERMINATION METHOD USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a mite-exterminating aqueous liquid composition which is highly effective to exterminate mites and is highly safe and to provide a mite extermination method using the same. SOLUTION: A mite-exterminating aqueous liquid composition in a first embodiment containing a cationic surfactant (A) and a polyvalent (≥divalent) anionic substance (B) is used. A mite-exterminating aqueous liquid composition in a second embodiment containing a cationic surfactant (A) and an alkali agent (C) and having a pH of 8.0 or higher is used. More desirably, a mite-exterminating aqueous liquid composition according to the second embodiment is used in conjunction with a polyvalent (≥divalent) anionic substance (B). It is desirable that the polyvalent anionic substance (B) used is one in which the number of the anionic groups per unit mass is 0.015 [eq/g] or larger. COPYRIGHT: (C)2008,JPO&INPIT
