  • Water soluble polymer powders with improved dispersibility
    Patent number: 9441118
    Abstract: The presently disclosed and claimed inventive concept(s) relates to a dry powder composition comprising water soluble polymer powders, and a component in powder form. The dry powder composition shows improved water dispersibility compared to the water soluble polymer powders. The presently disclosed and claimed inventive concept(s) further relates to an aqueous protective coating composition comprising the dry powder composition.
    Type: Grant
    Filed: July 2, 2013
    Date of Patent: September 13, 2016
    Assignee: Hercules Incorporated
    Inventors: Prachur Bhargava, Michael A. Tallon, Konstantin A. Vaynberg
  • Methods for dispersing water soluble polymer powder
    Patent number: 9321908
    Abstract: The present invention relates generally to a method for dispersing a dry cellulose ether powder in an aqueous solution without forming lumps using powder handling and mixing devices. The cellulose ethers can be cross-linked with an aldehyde cross-linker. An acid or partially neutralized acid is used to improve the solubility.

  • Control of fluid migration in wet-wipes
    Publication number: 20090081269
    Abstract: The present invention describes wet-wipe composition with a liquid portion that is impregnated in a substrate, wherein the liquid portion contains a binary pair of a thickening or gelling polymer along with a thickening or gelling agent which substantially reduces fluid migration of the liquid portion within a wet-wipes stack during storage.
