ABSTRACT:
Treating cigarette paper with (1) binary combinations of the sodium and potassium salts of a carboxylic acid or (2) binary combinations of an alkali metal chloride and an alkali metal carboxylate provides a means of controlling the static burning rate of cigarettes wrapped in these papers. Burn rate control is functionally implemented by varying (1) the sodium to potassium cation ratio at constant total alkali metal cation weight for the former binary combination and (2) the ratio of the alkali metal cation from the chloride to the alkali metal cation from the carboxylate at constant total alkali metal cation weight for the latter binary combination. This means of burn rate control is effective for cigarette papers containing various inorganic fillers and weighing less then 25 g/m.sup.2 to over 45 g/m.sup.2. Depending on the specific combination of salts, type cigarette paper and total alkali metal cation weight in the sheet, the static burning rate can be controlled over a range of 6 to 19 mg/min as the sodium/potassium ratio or alkali metal cation (from chloride)/alkali metal cation (from carboxylate) ratio is incrementally varied.
