ABSTRACT:
The burn rate of tobacco is decreased without impairment of its quality of smoking by the application thereto of small amounts of certain salts, preferably hydrated magnesium chloride, which upon heating exhibit a plurality of endothermic reactions at successively increasing temperatures in the range from about 100.degree. C. to about 500.degree. C. In addition, the presence of small amounts of an alkaline material such as calcium hydroxide is desired to counteract marginal changes in the yields of some smoke components and to increase smoke pH.
