  • Publication number: 20040047013
    Abstract: A method of inducing a sale of a product in a retail environment includes providing the product in a storage structure from which a potential purchaser may take physical possession of the product. A true hologram is provided to project a three-dimensional holographic image into a first space proximate to the storage structure to attract potential purchaser attention. The holographic image from the true hologram is used to communicate information about the product to the potential purchaser.

  • Publication number: 20040028629
    Abstract: Antiperspirant and/or deodorant compositions are disclosed that exhibit low white residue on both skin and fabric and which are formed by combining selected silicone polyamides with a selected co-gellant and an antiperspirant active having a high bulk density. The compositions may be formed as sticks, creams or roll-ons with good aesthetics.

  • Patent number: 6451295
    Abstract: Clear antiperspirant and/or deodorant compositions, especially clear sticks having good structural integrity, can be formed by incorporating at least 8% by weight based on the total weight of the composition of a selected siliconized polyamide into a product formulated with at least one silicone material and at least one non-silicone emollient. The siliconized polyamides have the silicone portion in the acid side of the polyamide and are selected so that: (a) the degree of polymerization in the silicone portion is in the range of 12-18; (b) the average molecular weight of the siliconized polyamide is at least 50,000 daltons with at least 95% of the polyamide having a molecular weight greater than 10,000 as measured by size exclusion chromatography; and (c) the polydispersity is less than 20.

  • Patent number: 6353076
    Abstract: An invention is disclosed which comprises siloxane-based polyamides as gelling agents for cosmetic products, methods for making such agents, formulations thereof and cosmetic formulations therewith. These polyamides contain siloxane groups in the main chain and act to thicken compositions containing volatile and/or non-volatile silicone fluids.

  • Patent number: 6342210
    Abstract: A method for forming micronized antiperspirant salts is disclosed wherein the method comprises the steps of: (1) forming an aqueous salt solution of a parent salt wherein the solution has a glycol content of less than 5 weight %; (2) pouring the salt solution onto a bounded flat surface; (3) evaporating the solvent from the salt solution so as to form a glass; (4) breaking up the glass using one or more steps to form particles having an average size in the range of 0.5-2.00 cm2; (5) mixing the particles from step (4) with a non-aqueous liquid vehicle in which the salt is not appreciably soluble and subjecting the mixture to an intermediate grinding process to form a suspension with particles having an average size of less than 200 microns; and (6) grinding the mixture from step (5) at a temperature in the range of 20-70 degrees C. without added water or external heating being required so that the particles in the suspension have an average particle size of less than or equal to 20 microns.
