Liquid nicotine formulation comprising water-immiscible solvents

A liquid nicotine formulation for an aerosol-generating system, the liquid nicotine formulation comprising:

• at least one of water and one or more water-miscible solvents;
• one or more partially water-soluble, water-immiscible solvents having a water solubility at 20° C. of between about 20 mg/ml and about 100 mg/ml;
• and
• one or more water insoluble, water-immiscible solvents having a water solubility at 20° C. of less than or equal to about 5 mg/ml,
• wherein the liquid nicotine formulation has a water-insoluble, water-immiscible solvent content of greater than or equal to about 2 percent by weight.

A liquid nicotine formulation for an aerosol-generating system, the liquid nicotine formulation comprising:

• at least one of water and one or more water-miscible solvents;
• one or more partially water-soluble, water-immiscible solvents having a partition coefficient (log P) at 20° C. of between about 0.05 and about 0.5;
• and
• one or more water insoluble, water-immiscible solvents a having a partition coefficient (log P) at 20° C. of greater than about 5,
• wherein the liquid nicotine formulation has a water-insoluble, water-immiscible solvent content of greater than or equal to about 2 percent by weight.
