Abstract

1400197 Tobacco-smoke filters BRITISHAMERICAN TOBACCO CO Ltd 7 Sept 1972 [26 Jan 1972] 41616/72 Heading A2C The filters, which have selectively enhanced filtering efficiency towards hydrogen cyanide and hydrogen sulphide, comprise a carrier of fibrous or filamentary cellulose acetate on which is supported a stabilized mixture comprising a plasticizer, zinc oxide, and either sodium carbonate, potassium carbonate or a mixture thereof, the molar ratio of zinc oxide to carbonate salt being from about 25 to 1 to 1 to 25. In the examples, the zinc oxide and the carbonate are milled with a plasticizer comprising a mixture of triethylene glycol diacetate and polyethylene glycol to form a stable dispersion which is then sprayed onto a bloomed cellulose acetate tow and the tow formed into filter rods.
