  • Example 1 which comprises a metal-supported inorganic support containing a support and having a second inorganic support and copper supported on the second inorganic support as the second metal-containing inorganic substance, Compared with the method of Example 10, it had the superior effect of the present invention. Moreover, the composition further contains an inorganic substance containing a third metal different from any of the first metal and the second metal, and the inorganic substance contains a phosphorus atom. As compared with the method of Example 2, it had a superior effect of the present invention.

Abstract

La présente invention concerne un procédé d'inhibition d'odeur avec lequel il est possible d'inhiber l'odeur d'un objet à désodoriser. La présente invention concerne également une composition, un chiffon et un pulvérisateur. Ce procédé d'inhibition d'odeur inhibe l'odeur provenant de bactéries par mise en contact d'une composition contenant au moins un élément choisi dans le groupe constitué par une substance inorganique contenant un premier métal, une substance inorganique contenant un second métal différent du premier métal, et une substance organique contenant le second métal avec un objet à désodoriser qui contient au moins une bactérie sélectionnée dans le groupe comprenant les genres Klebsiella, Citrobacter, Enterobacter, Proteus, Pseudomonas, Serratia et Morganella.
