## Abstract

A sheet is provided, including a fibrous material, one or more nicotine salts, and a binder, at least about 20% by weight of the one or more nicotine salts being monoprotic.

## Claims

### Claim 1

An aerosol-generating article comprising an aerosol-forming substrate, the aerosol-forming substrate comprising a sheet comprising:
a fibrous material;
one or more nicotine salts; and
a binder,
wherein at least about 20% by weight of the one or more nicotine salts is monoprotic,
wherein the sheet has a binder content of about 1% to 6% by weight on a dry weight basis,
wherein the aerosol-forming substrate further comprises one or more aerosol formers, and
wherein the aerosol-forming substrate has an aerosol former content of at least 10 percent by weight on a dry weight basis.

### Claim 2 (depends on 1)

The aerosol-generating article according to claim 1, wherein the sheet has a binder content of 6% to 8% by weight on a dry weight basis.

### Claim 3 (depends on 1)

The aerosol-generating article according to claim 1, wherein the sheet further comprises one or more gum binders.

### Claim 4 (depends on 1)

The aerosol-generating article according to claim 1, wherein the sheet further comprises one or more natural gum binders selected from the group consisting of guar gum, xanthan gum, and gum arabic.

### Claim 5 (depends on 1)

The aerosol-generating article according to claim 1, wherein a weight ratio of the binder to the one or more nicotine salts in the sheet on a dry weight basis is between about 2:1 and about 1:2.

### Claim 6 (depends on 1)

The aerosol-generating article according to claim 1, wherein the one or more nicotine salts is selected from the group consisting of nicotine acetate, nicotine benzoate, nicotine gallate, nicotine lactate, nicotine laurate, nicotine levulinate, nicotine palmitate, nicotine pyruvate, nicotine sorbate, and nicotine stearate.

### Claim 7 (depends on 1)

The aerosol-generating article according to claim 1, wherein the sheet further comprises sugar.

### Claim 8 (depends on 7)

The aerosol-generating article according to claim 7, wherein a weight ratio of reducing sugar to total sugar in the sheet on a dry weight basis is less than about 1:2.

### Claim 9 (depends on 1)

The aerosol-generating article according to claim 1, wherein the sheet further comprises one or more aerosol formers selected from the group consisting of propylene glycol, triethylene glycol, 1,3-butanediol, and glycerine.

### Claim 10 (depends on 1)

The aerosol-generating article according to claim 1, wherein the sheet further comprises less than about 5% by weight of tobacco material on a dry weight basis.

### Claim 11 (depends on 1)

The aerosol-generating article according to claim 1, wherein the sheet is a gathered sheet and the gathered sheet is circumscribed by a wrapper to form an aerosol-generating rod.

### Claim 12 (depends on 11)

The aerosol-generating article according to claim 11, wherein the gathered sheet is crimped.

### Claim 13 (depends on 11)

The aerosol-generating article according to claim 11, further comprising a combustible heat source,
wherein the aerosol-generating rod is disposed downstream of the combustible heat source.

### Claim 14 (depends on 11)

The aerosol-generating article according to claim 11, the aerosol-generating article being disposed as part of an electrically heatable aerosol-generating system.
