Abstract
Nicotine-containing formulations for electric/electronic nicotine delivery systems are disclosed, containing both nicotine at relatively much higher concentrations, typically at least 25% by weight of total formulation weight, w/w, and in many cases as much as 40-50% w/w, than is typical for conventional nicotine containing formulations, which only contain about 2-4% w/w nicotine. The formulations also include a biologically and pharmaceutically acceptable mono- or di-carboxylic organic acid, such as benzoic acid, salicylic acid and most preferably lactic acid also at relatively high w/w concentrations. One or more nicotine salts may be created and be extant within the formulations, which not only mitigates against the loss of nicotine to the atmosphere through natural volatility and evaporation, but also markedly increases the surface energy of the formulations created, and the globules of formulations deposited on a heating substrate are much more cohesive and much less likely to migrate through wetting over the substrate.
