Patents by Inventor Liang Sheng Tsaur

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).

  • Patent number: 7879780
    Abstract: The invention provides liquid cleanser compositions which contain fatty acyl isethionates surfactant products having at least 10 wt. % free fatty acid and/or fatty acid soap as the primary surfactant at a level at least 40 wt. % of total fatty acyl isethionate and synthetic cosurfactants in the liquid composition. The key is use of 10% to 60% glycerin and/or sorbitol which has been found, quite unpredictably, to stabilize compositions containing products of such high fatty acid and/or fatty acid soap content.
    Type: Grant
    Filed: September 23, 2008
    Date of Patent: February 1, 2011
    Assignee: Conopco, Inc.
    Inventor: Liang Sheng Tsaur
  • Patent number: 7842301
    Abstract: The invention provides process for making wet skin treatment compositions for use during bathing. The compositions are activated by water and retained efficiently on skin. The compositions impart desirable benefits to skin, are perceived to absorb quickly on wet skin, and leave the skin feeling clean, but non-greasy.

  • Patent number: 7807612
    Abstract: The invention provides personal care or hair liquid cleansing compositions comprising fatty acyl isethionate products having more than 5% by wt. free fatty acid/fatty soaps which are stabilized using specific mixture of long chain and short chain fatty acids/fatty soaps; as well as by using proper ratio of total linear fatty acid/fatty soap to total synthetic surfactants (the total synthetic is the sum of (1) fatty acyl surfactant component of (a)—that is, the “pure” fatty acyl isethionate which does not include free fatty acids and/or fatty acid soaps in the fatty acyl surfactant “product”—and (2) the synthetic co-surfactant of (b)).

  • Patent number: 7674759
    Abstract: The invention provides liquid cleanser compositions which contains fatty acyl isethionate surfactant products having at least 10 wt % free fatty acid and/or fatty acid salt used as the primary surfactant at a level at least 60 wt % of total fatty acyl isethionate and synthetic cosurfactants in the liquid composition. The key is to insure a specific combination of surfactant crystal modifiers so that the fatty acyl isethionate-containing liquid composition will be stable at low and high temperatures.

  • Patent number: 7671000
    Abstract: The invention provides liquid cleanser compositions which can use fatty acyl isethionates surfactant products, regardless of free fatty acid and/or fatty acid salt content of isethionate mixture or chain length distribution of isethionates mixture. The key is to insure a specific combination of liquid crystal inducer (of surfactant phase) and of modifier so that the isethionates will be stable at low and high temperatures.

  • Publication number: 20100035783
    Abstract: A stable, multiphase liquid isotropic cleansing composition is described that contains high levels of Petrolatum and shows a substantial decrease in reflectance compared with isotropic cleansing compositions containing other oils and liquid crystalline compositions with similar levels of oils. The inventive composition has a total of less than 2% by wt. of other oils such as glyceride, mineral and silicone oils, or blends thereof.

  • Patent number: 7024037
    Abstract: A process for measuring skin ashing is provided. The process comprises selecting a desired skin testing area and acguiring an image of the area using x-polarization technique. The image is analyzed by obtaining a light distributing image, storing the difference between this image and the original image and using a differential in intensity to define ashing.
