## Abstract

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.

## Claims

### Claim 1

A method for treating body perspiration and/or body odors associated with said perspiration, comprising an application to the skin surface an effective amount of an antiperspirant/deodorant composition comprising at least one polymer selected from the group consisting of PVM/MA copolymer, crosslinked PVM/MA copolymer, PVM/MA decadiene crosspolymer, IB/MA copolymer, and combinations thereof as the sole active antiperspirant/deodorant species, wherein said composition is essentially free of aluminum cations or zirconium cations.

### Claim 2 (depends on 1)

The method according to claim 1, wherein the composition has from 0.1% (w/w) to 15% (w/w) of said polymer.

### Claim 3 (depends on 1)

The method according to claim 1 wherein the percentage of perspiration reduction provided by said composition is greater than a placebo control absent said polymer, aluminum cations, and zirconium cations.

### Claim 4 (depends on 1)

The method according to claim 1, wherein the composition further comprises: an additional ingredient selected from the group consisting of absorbent, agent, antimicrobial, dye or colorant, emollient, moisturizer, fragrance, perfume, volatile oil, emulsifier, humectant, diluent, bulking agent, distributing agents, rheology agent, glyceride oil, silica, hair growth inhibitor, pharmaceutical active, UV active, preservative, surfactant, solvent, wash-off aid, and combinations thereof.

### Claim 5 (depends on 1)

The method according to claim 1, wherein the composition has the form of a stick, wax, powder, aerosol spray, pump spray, mist spray, roll-on, wipe, gel, cream, soft solid, or lotion.
