Abstract
The disclosure provides methods of stabilizing liquid aerosol precursor compositions adapted for use in an aerosol delivery device by incorporating one or more stabilizing agents. The disclosure further provides liquid aerosol precursor compositions containing one or more stabilizing agent. The disclosure further provides devices and kits incorporating such compositions.
Claims27
A method of enhancing the stability of a flavorant within a liquid aerosol precursor composition, comprising incorporating one or more stabilizing agents in a liquid aerosol precursor composition to give a stabilized liquid aerosol precursor composition with enhanced shelf life as compared to the liquid aerosol precursor composition,
- wherein the one or more stabilizing agents are selected from the group consisting of polysorbates, sorbitan esters, binders, monoglycerides, diglycerides, triglycerides, free fatty acids, waxes, preservatives, and combinations thereof, and
- wherein the one or more stabilizing agents are different than any components otherwise present in the liquid aerosol precursor composition.
A method of enhancing the stability of a flavorant within a liquid aerosol precursor composition, comprising incorporating one or more stabilizing agents in a liquid aerosol precursor composition to give a stabilized liquid aerosol precursor composition with enhanced shelf life as compared to the liquid aerosol precursor composition,
- wherein the one or more stabilizing agents comprise a sugar alcohol in an amount greater than 10% by weight of the stabilized liquid aerosol precursor composition, or
- wherein the one or more stabilizing agents comprise a non-sugar based polyol, and
- wherein the one or more stabilizing agents are different than any components otherwise present in the liquid aerosol precursor composition.
