Liang Sheng Tsaur 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).

  • Bar composition comprising low viscosity oils pre-thickened by non-antifoaming hydrophobic polymers
    Patent number: 5817609
    Abstract: The present invention relates to personal wash bar compositions comprising hydrophobic, low viscosity (less than 1000 cp) emollient agents which have been specifically pre-thickened with defined polymer composition. Use of the specific thickeners allow incorporation of the low viscosity oil (viscosity less than 1000 cp) in the personal wash compositions to deliver enhanced skin benefits and desired user properties without compromising foaming and bar processing.
    Type: Grant
    Filed: January 8, 1997
    Date of Patent: October 6, 1998
    Assignee: Lever Brothers Company, Division of Conopco, Inc.
    Inventors: Mengtao He, Michael Massaro, Gregory McFann, Liang Sheng Tsaur, Gail Beth Rattinger, Michael Paul Aronson
  • Personal wash liquid composition comprising low viscosity oils pre-thickened by non-antifoaming hydrophobic polymers
    Patent number: 5804540
    Abstract: The present invention relates to aqueous-based personal wash compositions comprising hydrophobic, low viscosity (less than 1000 cp) emollient agents which have been specifically pre-thickened with defined polymer composition. Use of the specific thickeners allow incorporation of the low viscosity oil (viscosity less than 1000 cp) in the personal wash compositions to deliver enhanced skin benefits and desired user properties without compromising foaming.

  • Process for making bar compositions having enhanced deposition of benefit agent comprising use of specific spray dryable adjuvant powders
    Patent number: 5770556
    Abstract: A process for making bars having enhanced deposition of benefit agent wherein the process comprises mixing adjuvant powder compositions which contain a benefit agent or agents and surfactant-containing "base" or regular chips; plodding and extruding to form final bar.
    Type: Grant
    Filed: March 21, 1997
    Date of Patent: June 23, 1998

  • 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.
