Abstract
Abstract A deodorizing composition, particularly for use in ash trays, in direct contact with the butts of cigarettes and cigars, comprising a granular absorbent substance which is incombustible at the combustion temperature of the glowing fire of the cigarettes or the like, containing absorbed therein an oily vapor diffuser substance. Advantageously, the absorbent substance is porous silica, having a grain size of 20 to 60 mesh per square centimeter, and an absorptive power of up to 1 part by weight of absorbed oily substance per part by weight of absorbing granular substance.
