Nicotine salt formulations for aerosol devices and methods thereof
A nicotine salt liquid formulation for generating an inhalable aerosol in an electronic cigarette comprising nicotine salt that forms about 0.5% to about 20% nicotine is provided.
1. An electronic cigarette comprising a cartridge, wherein the cartridge comprises a nicotine salt liquid formulation, wherein:
(a) the nicotine salt liquid formulation comprises a salt of nicotine and an organic acid in a liquid carrier, wherein the organic acid is benzoic acid or lactic acid;
(b) the salt is present in an amount that forms a nicotine concentration of 0.5% (w/w) to 20% (w/w) in the nicotine salt liquid formulation;
(c) the liquid carrier comprises glycerol and propylene glycol; and
(d) the nicotine salt liquid formulation generates an inhalable aerosol upon heating in the electronic cigarette.
2. The electronic cigarette of claim 1 , wherein the liquid carrier further comprises water.
3. The electronic cigarette of claim 1 , wherein the salt is present in an amount that forms a nicotine concentration of 1% (w/w) to 18% (w/w) in the nicotine salt liquid formulation.
4. The electronic cigarette of claim 1 , wherein the salt is present in an amount that forms a nicotine concentration of 3% (w/w) to 15% (w/w) in the nicotine salt liquid formulation.
5. The electronic cigarette of claim 1 , wherein the salt is present in an amount that forms a nicotine concentration of 4% (w/w) to 12% (w/w) in the nicotine salt liquid formulation.
6. The electronic cigarette of claim 1 , wherein the nicotine salt liquid formulation further comprises a flavorant.
7. The electronic cigarette of claim 1 , wherein the nicotine salt liquid formulation further comprises one or more additional organic acids.
8. The electronic cigarette of claim 1 , wherein the cartridge is configured to serve as a mouthpiece and a reservoir, wherein the reservoir holds the nicotine salt liquid formulation.
9. The electronic cigarette of claim 1 , wherein the organic acid is benzoic acid.
10. The electronic cigarette of claim 1 , wherein the organic acid is lactic acid.
11. A method of providing nicotine to a user, the method comprising:
(a) heating a nicotine salt liquid formulation in an electronic cigarette to produce an inhalable aerosol, and
(b) inhalation of the aerosol by the user;
wherein:
(i) the nicotine salt liquid formulation comprises a salt of nicotine and benzoic acid in a liquid carrier;
(ii) the salt is present in an amount that forms a nicotine concentration of 0.5% (w/w) to 20% (w/w) in the nicotine salt liquid formulation; and
(iii) the liquid carrier comprises glycerol and propylene glycol.
12. The method of claim 11 , wherein the liquid carrier further comprises water.
13. The method of claim 11 , wherein the salt is present in an amount that forms a nicotine concentration of 1% (w/w) to 20% (w/w) in the nicotine salt liquid formulation.
14. The method of claim 11 , wherein the salt is present in an amount that forms a nicotine concentration of 1% (w/w) to 18% (w/w) in the nicotine salt liquid formulation.
15. The method of claim 11 , wherein the salt is present in an amount that forms a nicotine concentration of 3% (w/w) to 15% (w/w) in the nicotine salt liquid formulation.
16. The method of claim 11 , wherein the salt is present in an amount that forms a nicotine concentration of 4% (w/w) to 12% (w/w) in the nicotine salt liquid formulation.
17. The method of claim 11 , wherein the nicotine salt liquid formulation further comprises a flavorant.
18. The method of claim 11 , wherein the nicotine salt liquid formulation further comprises one or more additional organic acids.
19. The method of claim 11 , wherein the electronic cigarette comprises a cartridge, and the cartridge is configured to serve as a mouthpiece and a reservoir, wherein the reservoir holds the nicotine salt liquid formulation.
