<p><P>PROBLEM TO BE SOLVED: To provide deodorizing dispersion excellent in deodorizing performance toward aldehyde-based gases such as acetaldehyde, formaldehyde, etc., and further a deodorant having an excellent deodorizing performance toward various bad smells other than those of aldehydes. <P>SOLUTION: This deodorizing dispersion of inorganic powdery material and aminoguanidine has the excellent performance as the deodorant for the aldehyde-based gases. Further, the deodorizing dispersion exhibits the deodorizing performance in a wide range of temperature. Furthermore, a substrate material treated with the deodorizing dispersion can suppress the scattering of the aldehyde gas generated from the material. That is, the aldehyde-based gas-deodorizing dispersion is the dispersion of the aminoguanidine salt and the inorganic powdery material, having 1 to 7 pH. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
