Margaret Jobling 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).

  • Aqueous solution compositions comprising polymer hydrogel compositions
    Patent number: 6066613
    Abstract: The invention relates to hydrogel dispersions/particles capable of trapping water insoluble beneficial agent, yet capable of disintegrating smoothly to impart desirable in use characteristics.
    Type: Grant
    Filed: November 6, 1997
    Date of Patent: May 23, 2000
    Assignee: Lever Brothers Company
    Inventors: Liang Sheng Tsaur, Shiji Shen, Margaret Jobling, Michael Paul Aronson
  • Cleansing composition comprising surfactant and internal emulsion comprising cosmetic agent, emulsifier and carrier
    Patent number: 5912002
    Abstract: A rinse-off cleansing composition including at least one surfactant-soluble cosmetic benefit agent and at least one surfactant is provided. The composition comprises a first emulsion having a continuous phase comprising the surfactant and an internal phase comprising a second emulsion. The second emulsion has a continuous phase comprising a carrier in which the cosmetic benefit agent is substantially insoluble and an internal phase comprising the cosmetic benefit agent and an emulsifier therefor. The carrier is surfactant-insoluble. By protecting the cosmetic benefit agent enhanced deposition thereof is achieved during use of the composition.

    Inventors: Ailsa Pauline Grieveson, Margaret Jobling
  • Process for making aqueous solution compositions comprising polymer hydrogel compositions
    Patent number: 5759969
    Abstract: The invention relates to a process for making hydrogel dispersions/particles capable of trapping water insoluble beneficial agent, yet capable of disintegrating smoothly to impart desirable in use characteristics.
    Type: Grant
    Filed: August 27, 1996
    Date of Patent: June 2, 1998
    Assignee: Lever Brothers Company, Division of Conopco, Inc.
    Inventors: Liang Sheng Tsaur, Shiji Shen, Margaret Jobling, Michael Paul Aronson
  • Aqueous solution compositions comprising polymer hydrogel compositions
    Patent number: 5726138
    Abstract: The invention relates to hydrogel dispersions/particles capable of trapping water insoluble beneficial agent, yet capable of disintegrating smoothly to impart desirable in use characteristics.
    Type: Grant
    Filed: August 26, 1996

  • Detergent composition
    Patent number: 5661189
    Abstract: An aqueous liquid cleansing and moisturising composition comprising a surface active agent selected from anionic, nonionic, zwitterionic and cationic surface active agents and mixtures thereof; an benefit agent having a weight average particle size in the range 50 to 500 microns; and a thickening agent. The thickening agent is added to the benefit agent in amount from 1 to 50% wt, based on the benefit agent.
    Type: Grant
    Filed: June 6, 1995
    Date of Patent: August 26, 1997
    Assignee: Lever Brothers Company, Division of Conopco, Inc.
    Inventors: Ailsa Pauline Hilary Grieveson, Margaret Jobling, Shiji Shen, Liang Sheng Tsaur
  • Detergent compositions containing separate stripes of surface active agents and benefit agent
    Patent number: 5612307
    Abstract: An aqueous liquid cleansing and moisturising composition comprising a surface active agent and a benefit agent in which the surface active agent and benefit agent are separate but combinedly dispensable from a single packaging means in a predetermined ratio as discrete domains. Separating the benefit agent from the surface active agent results in improved deposition of the benefit agent.
