摘要:A synthetic nicotine composition comprising synthetic nicotine, a synthetic nicotine salt and a synthetic nicotine derivative, wherein the synthetic nicotine, the synthetic nicotine salt, and the synthetic nicotine derivative are in mass percentage; the synthetic nicotine accounts for 1-20%, the synthetic nicotine salt accounts for 30-70%, and the synthetic nicotine derivative accounts for 20-50%; and the synthetic nicotine is one or more of S-nicotine and a mixture of R-nicotine containing a racemate and S-nicotine. The synthetic nicotine, synthetic nicotine salt and synthetic nicotine derivative according to the present invention are proportionally mixed to prepare an existing synthetic nicotine product, which relieves the problem of the impact of impurities in natural extracted nicotine products causing an unpleasant smell, a bitter taste and a strong volatility, and can be used in the fields of low temperature heat-not-burn products, snuff, electronic cigarettes, nicotine release patches, insecticides, herbicides, microbicides, drug synthesis, etc.
