    Abstract: Described is a fragrancing composition having fragrancing components that are not activated until, e.g., application to the skin of a human. The composition is alkaline or (if anhydrous) capable of producing an alkaline pH when in contact with water, prior to application, and includes (1) a vehicle for application of the composition, and (2) at least one potential fragrance that is at least one compound having little or no odor in the alkaline composition but which, e.g., is hydrolyzed in a lower pH environment to produce compounds having a relatively strong aroma. Upon application of the alkaline composition to the skin surface, the strong buffering capacity of the skin (the surface of which has a normal pH of 5.5-7.0) neutralizes alkalinity of the composition (lowers pH) so as to restore normal skin surface pH; the potential fragrance is then hydrolyzed at the lower pH to release the compound having relatively strong aroma.

  • Patent number: 5356612
    Abstract: Antiperspirant effectiveness of basic aluminum chloride is increased by mixing it with monosilicic acid in aqueous solution. The product can be dried to a solid, and the antiperspirant effectiveness does not decrease in contact with water. The product can also be characterized by size exclusion chromatography of its approximately 10% by weight aqueous solution. Zirconyl hydroxy chloride may also be present.

  • Patent number: 5354553
    Abstract: This invention provides an improved process for producing an antiperspirant-deodorant cosmetic stick product. An essential aspect of the process improvement is a phased order of ingredient addition and blending of formulation ingredients under controlled temperature conditions. Another essential aspect is the incorporation of particulate antiperspirant and alkali metal bicarbonate ingredients, at least one of which has ingredient particle surfaces coated with a hydrophilic organic polymer.

  • Patent number: 5346694
    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.
