  • Patent number: 7078046
    Abstract: Disclosed are electrostatically-sprayable topical compositions, more particularly topical emulsion compositions, and methods of treating the skin by electrostatic application of such compositions. In one aspect the composition comprises an insulating external phase comprising one or more insulating materials and a conductive internal phase comprising one or more conductive materials. The compositions preferably also contain one or more particulate materials to be deposited on the skin, e.g., pigments, inert absorbents and the like.
    Type: Grant
    Filed: July 31, 2000
    Date of Patent: July 18, 2006
    Assignee: The Procter & Gamble Company

  • Patent number: 6558682
    Abstract: The present invention relates to substantially uniform, discontinuous films of a skin care product having a defined average particle size, particle spacing and coverage value. The films provide improved skin appearance, e.g., good apparent coverage and a natural look. The films can be formed by any method which provides the defined particle size, particle spacing and coverage value, including silk screening and the like and electrostatic spray techniques. The films are preferably formed by electrostatically spraying the composition onto the skin.

  • Patent number: 6531142
    Abstract: Disclosed are stabilized electrostatically-sprayable topical compositions and methods of treating the skin by electrostatic application of such compositions. The compositions comprise: a) from about 2% to about 90% of a liquid insulating material; b) from about 2% to about 90% of a conductive material; c) from about 0.1% to about 35% of a particulate material which is insoluble and immiscible in the composition; and d) from about 0.5% to about 30% of a thickener for stabilizing the composition. The liquid insulating materials and conductive materials present in the composition are sufficiently miscible or soluble in the composition such that they are in substantially one phase.

  • Patent number: 6461626
    Abstract: The present invention relates to substantially uniform, discontinuous films of a topical product having a defined abrasion resistance, coverage value and particle spacing. The films are wear or transfer resistant and provide good skin coverage, while simultaneously providing improved skin appearance, e.g., good apparent coverage and a natural look. The films can be formed by methods which provide the defined particle coverage and spacing, including silk screening and the like and electrostatic spray techniques. The films are preferably formed by electrostatically spraying the composition onto the skin.
