Antiperspirant/deodorant compositions have lower, or even zero amounts of aluminum and/or zirconium antiperspirant actives. A polymer having one or more anhydride and/or diacid moieties, such as succinic (maleic) anhydride and/or diacid. The antiperspirant/deodorant compositions comprise a polymer with a non-zero acid value and a cationic species, which may be a cationic polymer, cationic molecule, cation, and/or a cationic carrier. Product are formed for the antiperspirant/deodorant composition, as well as a method of treating perspiration.
