Patent number: 5635191Abstract: A diaper containing a liquid pervious topsheet coated with a lotion composition is disclosed. The lotion composition reduces the adherence of BM to the skin of the wearer, thereby improving the ease of BM clean up. The lotion composition comprises a plastic or fluid polysiloxane emollient such as phenyl-functional polymethylsiloxanes, an immobilizing agent such as a fatty alcohol or paraffin wax to immobilize the emollient on the surface of the diaper topsheet, and optionally a hydrophilic surfactant to improve wettability of the coated topsheet. Because the polysiloxane emollient is substantially immobilized on the surface of the topsheet, less lotion is required to impart the desired therapeutic or protective lotion coating benefits.Type: GrantFiled: November 28, 1994Date of Patent: June 3, 1997Assignee: The Procter & Gamble CompanyInventors: Donald C. Roe, Larry N. Mackey

Patent number: 4986882Abstract: Processes are described for making highly absorbent tissues and towels by wet-laying pulps comprising particular polycarboxylate polymer-modified fibrous pulps such as mildly hydrolyzed methyl acrylate-grafted softwood kraft pulps; these pulps have distinct protonated and alkali-metal-cation-exchanged states. The wet-laying processes are adapted to exploit the very different behavior of the polymer-modified fibrous pulps in function of the two states. The preferred wet-laying processes described herein are continuous processes embodying one or more on-line chemical treatment steps which chemically switch state of the polymer-modified fibrous pulp component in a wet web on the papermaking machine to improve the processing thereof by averting or minimizing tendencies to mechanically or thermally degrade.Type: GrantFiled: July 11, 1989Date of Patent: January 22, 1991Assignee: The Proctor & Gamble CompanyInventors: Larry N.
