1390777 Tobacco compositions; tobacco substitutes HAARMANN & REIMER GmbH 20 Nov 1972 [19 Nov 1971 29 March 1972] 53504/72 Heading A2C A smokeable product comprises a combustible material based on cellulose and at least one trivalent-metal chelate compound of an alkaline earth and/or of divalent manganese, the "trivalent-metal chelate compound" having a complex anion which contains at least one atom of trivalent iron and/or aluminium as a central atom and at least one anion of a chelate-forming organic carboxylic acid as a-ligand. The combustible material may be tobacco, reconstituted waste tobacco, cotton linters, wood pulp, decomposed cellulose-containing plant material such as hay, straw, lupins or fern, as well as cellulose derivatives such as carboxymethyl, hydroxyethyl or methyl celluloses, or oxidised or thermally degraded celluloses. The combustible material may include a conventional inert filler or one which splits off water under smoking conditions. Other additives include compounds which split off ammonia under smoking conditions which may be: ammonium salts of organic or inorganic acids, which may include the ammonium salts corresponding to the chelates of the invention; acid amides such as acetamide or urea; or ammonium, magnesium or manganous salts of amino acids. Other ingredients mentioned include: oxidising agents, especially potassium permanganate; ammonium salts of pectin, alginic acid and gum arabic; low sulphurcontent proteins, e.g. zein, hordein or gliadin, or their alcoholic extracts; aqueous or organic solvent tobacco extracts; and conventional binding agents. Long lists of the above referred to ingredients are given, and many are exemplified in over 50 examples. The chelate compounds exemplified are various combinations of neutral or acid magnesium or manganous salts of ferric or aluminium complexes with citric, tartaric, oxalic, glycollic or galactaric acids.
