Abstract

Method method for making a chemically-treated filter element for cigarettes, to reduce the concentration of nitro­ gen oxide by-products in cigarette smoke, by applying a non-­ ionic solution or dispersion containing zinc oxide or zinc acetate to the substrate in the garniture feed, the non-ionic solution or dispersion also containing a polyoxyalkylene derivative of a sorbitan fatty acid ester, a monoester of a polyhydroxyalcohol, or a diester of a polyhydroxy alcohol, or containing a mixture of the said dispersants.
