Study on Mainstream Smoke Characteristics and Their risks of Low Ignite Propensity Cigarettes

摘要

To learn differences and mainstream smoke (MSS) risks of between Low ignite propensity (LIP) cigarettes and the common, their MSS and 7 main harmful compounds in MSS are analyzed, and their MSS risks are also evaluated. The results indicate that: (1) It will improve yields of tar, nicotine, HCN and other main harmful compounds in MSS of the cigarette rolled with LIP cigarette paper replaced of common cigarette paper, and lead risks of their MSS to increase; (2) It is a way to reduce yields of some main harmful compounds and lower risks of their MSS risks of LIP cigarette paper with higher diffusion rate of flame retardant bar or higher original porosity; (3) The LIP cigarette paper produced by hemp pulp rather than wood pulp can also reduce appropriately yields of NH_3, CO and other harmful compounds and lower their MSS risks of the LIP cigarettes.
