Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: Disclosed are selenium sulfide lotion shampoos containing peroxy oxidizing agents, such as hydrogen peroxide and sodium percarbonate. These compositions provide antidandruff efficacy and do not become discolored upon storage. A method for preparing color-stable selenium sulfide shampoo compositions is also taught.

Abstract: The present invention relates to processes for purifying quaternary cationic surfactant materials and rendering said materials substantially free of ultraviolet absorbing impurities having a maximum absorption in the range of from about 260 nm to about 280 nm. This invention also relates compositions containing purified quaternary cationic surfactant materials.

Abstract: Aqueous depilatory compositions containing biguanide and active thiol agent(s) which provide for faster hair removal are disclosed.

Abstract: A method for coloring hair comprising sequentially treating the hair with a solution of water soluble ferric ion salt and with a carboxylic acid solution.

Abstract: Oral compositions such as toothpastes, mouthwashes, and the like containing particular substantive bis-biguanide compounds which inhibit the formation of plaque and caries.
