Abstract
An aerosol-generating system is provided, including a nicotine source; and a delivery enhancing compound source, which includes a reaction product of one or both of: (i) an alpha-keto carboxylic acid and a compound of formula (I) where R1 is selected from alkyl, phenyl, or substituted phenyl, and (ii) an alpha-hydroxy acid and a compound of formula (II) where X is a halogen and R2 is selected from H, alkyl, phenyl, or substituted phenyl.
Claims15
An aerosol-generating system, comprising:
- a nicotine source;
- and
- a delivery enhancing compound source,
- wherein the delivery enhancing compound source comprises a reaction product of one or both of:
- (i) an alpha-keto carboxylic acid and a compound of formula (I)
- where R1 is selected from alkyl, phenyl, or substituted phenyl;
- and
- (ii) an alpha-hydroxy acid and a compound of formula (II)
- where X is a halogen and R2 is selected from H, alkyl, phenyl, or substituted phenyl.
An aerosol-generating article for an aerosol-generating system, the aerosol-generating article comprising:
- a nicotine source and a delivery enhancing compound source,
- the aerosol-generating article being removably insertable into an aerosol-generating device,
- wherein the delivery enhancing compound source comprises a reaction product of one or both of:
- (i) an alpha-keto carboxylic acid and a compound of formula (I)
- where R1 is selected from alkyl, phenyl, or substituted phenyl;
- and
- (ii) an alpha-hydroxy acid and a compound of formula (II)
- where X is a halogen and R2 is selected from H, alkyl, phenyl, or substituted phenyl.
A method of generating an aerosol comprising nicotine salt particles, comprising:
- reacting nicotine with a reaction product of one or both of:
- (i) an alpha-keto carboxylic acid and a compound of formula (I)
- where R1 is selected from alkyl, phenyl, or substituted phenyl;
- and
- (ii) an alpha-hydroxy acid and a compound of formula (II)
- where X is a halogen and R2 is selected from H, alkyl, phenyl, or substituted phenyl.
An aerosol-generating system for generating an aerosol comprising nicotine salt particles, comprising:
- a nicotine source;
- and
- a delivery enhancing compound source comprising one or both of:
- (i) 2,4-dimethyl-1,3-dioxolane-2-carboxylic acid;
- and
- (ii) 2-(allyloxy)propanoic acid.
