<p>PURPOSE:To obtain an acidic malodor deodorant having a high lasting property to the increase and decrease of a malodor, by adding not only a metal generating oxygen through the reaction with a humus substance but also carbonate to an activated humus substance covered with a semipermeable membrane before molding. CONSTITUTION:0.3-1.0pts. of Na-alginate and 0.2-0.5pts. of CaCl2 are added to 5pts. of an activated humus substance with fulvic acid content of 5% or more, humic acid content of 3% or more and moisture content of 50-75% to be kneaded and mixed therewith to coat the activated humus substance with a film of formed Ca-alginate. 3-5pts. of an iron powder (100 mesh or less) and 0.1-0.3pts. of CaCO3 as a porosity imparting substance are added to and kneaded and mixed with the coated activated humus substance and the resulting kneaded mixture is molded into a pellet or honeycomb form and dried. Because the activated humus substance is finely partitioned by the semipermeable membrane and reaction generating oxygen is generated between the activated humus substance and the iron powder only in the small section contacted with an acidic malodor, a deodorant having a high lasting property can be obtained.</p> |
