R′ is hydrogen, an alkali metal, an alkaline earth metal, substituted C1-C18 alkyl, or unsubstituted C1-C18 alkyl; and
R″ is hydrogen or substituted or unsubstituted C1-C12 alkyl, where the two R″ groups in CON(R″)2 and N(R″)2 may be independently selected;
X is halogen; and
M is an alkali or alkaline earth metal;
a carrier for the sulfonamide compound;
a thickener; and
an antiperspirant;
wherein the deodorant composition is in the form of a solid stick.

### Claim 2 (depends on 1)
