Disclosed is a process for making zirconium-aluminum salts for use as antiperspirant active, which process comprises the step of anhydrous mixing of a zirconium salt and an aluminum salt to form a zirconium-aluminum salt, wherein the mixture of zirconium and aluminum salts is substantially free of unbound water at all times during the process. The zirconium, aluminum and zirconium-aluminum salts in the process are in the form of particulate or other solids, or can otherwise be dissolved or dispersed in a non-aqueous medium. The process allows for the formation of zirconium-aluminum salts as antiperspirant active without relying upon prior art methods which teach that zirconium-aluminum salts require reaction together in an aqueous medium. This process is more stable than the prior art methods and provides better control over optimizing the polymer size distribution within the resulting zirconium-aluminum salts.

Disclosed are aqueous and anhydrous deodorant compositions which comprise from about 0.1% to about 89.9% by weight of a cyclodextrin odor controlling agent, from about 0.1% to about 30% by weight of a solid non-polymeric gellant and from about 10% to about 90% by weight of an aqueous or anhydrous liquid carrier. Also disclosed are methods of using and making the compositions. The disclosed compositions are especially effective at preventing or eliminating malodors resulting from perspiration.

Deodorant compositions containing cyclodextrin odor controlling agents

Antiperspirant compositions in the form of gel sticks, which provide the user with excellent antiperspirant efficacy while exhibiting good stability, are disclosed. These compositions utilize particular gelling agents which are stable under the acidic conditions required in antiperspirant compositions. Specifically, the compositions have an acidic pH and include an antiperspirant active, a gelling agent which comprises dibenzylidene alditols substituted on the benzene ring with an electron withdrawing group, and a solvent for the gelling agent. Examples of preferred gelling agents include di(meta-fluorobenzylidene) sorbitol and di(meta-chlorobenzylidene) sorbitol. The method of preventing and controlling perspiration wetness using these compositions is also disclosed.

Gel stick antiperspirant compositions

Antiperspirant compositions in the form of gel sticks, which provide the user with excellent antiperspirant efficacy while exhibiting good stability, are disclosed. Specifically, the compositions have an acidic pH and include an antiperspirant active, a gelling agent which comprises dibenzylidene alditols, a solvent for the gelling agent, and a gelling agent stabilizer which is a basic metallic salt of an acid having a pKa of from about 3.8 to about 6.5 at 25.degree. C, said salts being at least partially soluble in the composition, and said stabilizer being a salt selected from the group consisting of C.sub.4 -C.sub.6 alkyl dicarboxylates, C.sub.6 -C.sub.8 alkyl monocarboxylates, and substituted and unsubstituted benzoates, and mixtures thereof, wherein said gelling agent stabilizer does not contain amino or amido functionalities. Methods of preventing and controlling perspiration wetness using these compositions and of making the compositions are also disclosed.

Deodorant gel stick compositions, which are essentially free of water, comprising a heavy metal salt of 1-hydroxy pyridinethione as the deodorant active, a gelling agent, and a solvent system (preferably a polar solvent) are disclosed. These compositions have minimized component interactions, active component stability, and are excellent in the prevention of body malodors. Preferred compositions utilize zinc pyrithione as the deodorant active, and contain less than about 1% water. Other standard deodorant components may be included in compositions for cosmetic purposes.
