Abstract
A nicotine liquid formulation comprising nicotine, an acid, and a biologically acceptable liquid carrier, wherein heating an amount of said nicotine liquid formulation using low temperature electronic vaporization device, i.e. an electronic cigarette, generates an inhalable aerosol, and wherein at least about 50% of said acid in said amount is in said aerosol, and wherein at least about 90% of said nicotine in said amount is in said aerosol
Claims25
A method of generating an inhalable aerosol comprising nicotine for delivery to a user using an electronic vaporization device comprising a nicotine salt liquid formulation and a heater, the method comprising:
- (i) providing an amount of the nicotine salt liquid formulation to the heater, wherein
- (a) the nicotine salt liquid formulation comprises at least one nicotine salt in a biologically acceptable liquid carrier;
- (b) the at least one nicotine salt comprises a salt of nicotine and malic acid;
- (c) the nicotine salt liquid formulation has a nicotine salt concentration of about 0.5% (w/w) to about 20% (w/w);
- and
- (d) the nicotine salt liquid formulation has a molar ratio of malic acid to nicotine from about 0.7:1 to about 3:1, and
- (ii) forming an aerosol by heating the amount of the nicotine salt liquid formulation.
A nicotine salt liquid formulation comprising at least one nicotine salt in a biologically acceptable liquid carrier, wherein:
- (a) the at least one nicotine salt comprises a salt of nicotine and malic acid;
- (b) the nicotine salt liquid formulation has a nicotine salt concentration of about 1% (w/w) to about 20% (w/w);
- and
- (c) the nicotine salt liquid formulation has a molar ratio of malic acid to nicotine from about 0.7:1 to about 3:1.
