Debra S. Caswell has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Liquid detergent containing conditioning agent and high levels of alkyl sulfate/alkyl ethoxylated sulfate
    Patent number: 5073274
    Abstract: Disclosed are liquid detergent compositions containing from about 5% to about 40% of an alkyl sulfate or alkyl ethoxylated sulfate surfactant, or mixture thereof, and water-insoluble, amine-organic anion ion-pair conditioning particles in a liquid base. The alkyl sulfate, alkyl ethoxylated sulfate, or mixture thereof, stabilizes the conditioning particles for improved shelf-life.
    Type: Grant
    Filed: April 30, 1990
    Date of Patent: December 17, 1991
    Assignee: The Procter & Gamble Co.
    Inventor: Debra S. Caswell
  • Ion-pair complex conditioning agent with benzene sulfonate/alkyl benzene sulfonate anionic component and compositions containing same
    Patent number: 5019280
    Abstract: Disclosed are conditioning agents and compositions containing such conditioning agents wherein the conditioning agents contain an amine-anionic compound ion-pair complex. These conditioning agents can provide excellent fabric care benefits when applied as part of or in the presence of detergent compositions without significantly impairing cleaning performance. The conditioning agents contain particles which consist essentially of the ion-pair complex and which have an average particle diameter of from about 40 to about 300 microns.
    Type: Grant
    Filed: February 8, 1989
    Date of Patent: May 28, 1991
    Assignee: The Procter & Gamble Company
    Inventors: Debra S. Caswell, Mark H. Mao, Robert Mermelstein, Ellen S. Baker
  • Ion-pair complex conditioning agent and compositions containing same
    Patent number: 4915854
    Abstract: Disclosed are conditioning agents and compositions containing such conditioning agents wherein the conditioning agents contain an amine-anionic compound ion-pair complex. These conditioning agents can provide excellent fabric care benefits when applied as part of or in the presence of detergent compositions without significantly impairing cleaning performance. The conditioning agents contain particles which consist essentially of the ion-pair complex and which have an average particle diameter of from about 10 to about 300 microns.
    Type: Grant

  • Conditioning agent containing amine ion-pair complexes and composiitons thereof
    Patent number: 4861502
    Abstract: Disclosed are conditioning agents and compositions containing such conditioning agent, said conditioning agent being particles from about 5% to about 95%, by weight of said particles, of an amine-organic anion ion-pair complex and from about 95% to about 5%, by weight of said particles, of an amine-inorganic anion ion-pair complex. The particles have an average diameter of from 10 microns to about 500 microns. These conditioning agents can provide excellent fabric care benefits when applied as part of, or in the presence of, detergent compositions without significantly impairing cleaning performance.
