Definitions

• Non-tobacco smoking compositions comprising cellulosi'c material which has been treated, for example, with nitrogen dioxide so as to obtain a reduction in TPM.
• the basis of the method is understood to be the oxidation of the primary hydroxyl of cellulose to the carboxyl function.
• the oxidation procedure is claimed to have the effect of reducing the TPM delivery from cellulose paper sheet, whilst sweetening the taste of the smoke.
• the oxidation of cellulosic material with nitrogen dioxide involves high investment and operating costs.
• the process according to the invention comprises impregnation of a cellulosic sheet material, preferably paper sheet, with an aqueous solution of a polycarboxylic polymer comprising a carboxylic polysaccharide in the form of sodium alginate, pectinic or pectic acid or like carbohydrate (as an acid or salt), or a polyacrylic acid or a polyacrylic salt.
• a polycarboxylic polymer comprising a carboxylic polysaccharide in the form of sodium alginate, pectinic or pectic acid or like carbohydrate (as an acid or salt), or a polyacrylic acid or a polyacrylic salt.
• a flame-retarding agent such as certain sulphates and phosphates of magnesium, aluminium or sodium, for altering the puff number.
• EXAMPLE 1 A paper sheet of 20g/m was made on a Fourdrinier machine from alpha cellulose pulp. I
• Cigarettes were produced as in Example 1, but from paper sheet material containing 5% of the sodium alginate.
• the TPM delivery was 5 mg/cigarette at an average puff number of 4.5. (The puff number being the number of puffs to smoke the cigarettes to a butt length of 23 mm under the standard conditions described in Example 1).
• Cigarettes were produced as in Example 1, but containing 15% of the sodium alginate.
• the TPM delivery was 20 mg/cigarette.
• Cigarettes were produced as in Example 1, except that a solution of sodium alginate was prepared by dissolving analytical grade alginic acid in sodium hydroxide to neutrality and diluting the solution so that 10 ml applied to 5 g of the paper sheet gave a sheet containing 2% sodium alginate.
• the TPM delivery was 8 mg/cigarette.
• EXAMPLE 5 The procedure was as in Example 1, except that a commercial low methoxy pectin (pectinic acid) was dissolved and the viscous solution was painted on, using a brush spreader. Cigarettes made from sheet containing 2% pectin had a TPM delivery of 20 mg/cigarette.
• pectinic acid a commercial low methoxy pectin
• Cigarettes were produced as in Example 1, except that analytical grade 250 pectin was used. The TPM delivery was 20 mg/cigarette.
• Cigarettes were produced as in Example 1, except that a commercial ammonium salt of polyacrylic acid was applied to give a sheet containing 4.6% of this salt.
• the TPM delivery was 35 mg/cigarette at an average puff number of 9.
• EXAMPLE 8 i The sheet material of Example 1 was further treated by adding 5% of sodium phosphate after the application of the sodium alginate. The TPM delivery was reduced to 8 mg/cigarette at an average puff number of 5.0.
• EXAMPLE 9 The sheet material of Example 2 was further treated by adding 2% of magnesium sulphate heptahydrate after the application of the sodium alginate.
• the TPM delivery was 14.5 mg/cigarette at an average puff number of 6.6.
• Example 1 was followed, except that a paper reconstituted tobacco sheet was used instead of the alpha cellulose sheet.
• the TPM delivery was 24 mg/cigarette compared with 29 mg/cigarette for the untreated sheet. Both kinds of cigarette had the same average puff number.
• EXAMPLE 11 tion employed will advantageously be within the approximate range of 0.1% to 20% by weight and preferably within the range of 1% to The TPM delivery was found to range, in comparison with a minimum of 50 mg/cigarette for the untreated sheet material, from 14 mg/cigarette down to 5 mg/cigarette and up to 12.8 mg/cigarette with a progressive increase in the proportion of carboxyl-containing units.
• a process for manufacturing a smoking composition having a low total particulate matter delivery consisting essentially of:
• an alpha cellulose paper sheet having a density of about 20 grams per square meter with an aqueous solution of a material selected from the group consisting of pectinic acid and sodium algihate to thereby provide a 2% weight gain by impregnation of said sheet on a dry basis; then drying; and thereafter shredding said dried and impregnated sheet to provide filler material for cigarettes.
• the composition is a non-tobacco composition.
• a smoking composition or cigarette containing the same produced by a process according to claim 1.
