Publication number: 20040057986Abstract: The present invention relates to polymerized hydrogel adhesives, in particular those wherein the hydrogel is formed from monomers which include acrylamido-2-methane propanesulfonic acid or salts thereof (AMPS monomers) and those which contain glycerol as a humectant. In such adhesives, the levels of unpolymerized residual monomers, such as unpolymerized AMPS, acrylonitrile, acrylamide and t-butyl acrylamide; and the levels of other impurities such as acrolein, are kept very low.Type: ApplicationFiled: August 14, 2003Publication date: March 25, 2004Applicant: The Procter & Gamble CompanyInventors: Steve Ray Merrigan, Stephen A.

Patent number: 6395955Abstract: An article to be fitted to a wearer including an agent which is available in an effective concentration to physically or chemically modify some or all of the fecal material or other bodily exudates deposited in the article. The modification of the feces may improve acceptance and/or retention of the exudates within the article to reduce the spreading of fecal material within the diaper and/or to reduce the tendency of the fecal material to adhere to the wearer's skin.Type: GrantFiled: June 29, 1999Date of Patent: May 28, 2002Assignee: The Procter & Gamble CompanyInventors: Donald C.

Patent number: 6372953Abstract: Described are absorbent members useful in the containment of body liquids such as urine. These absorbent members comprise at least one osmotic absorbent (preferably a hydrogel-forming absorbent polymer) and a high surface area material, and have a high capillary suction capacity. For purposes of the present disclosure, capillary suction capacity is measured in terms of the member's ability to uptake liquid at high capillary heights, which are generally encountered when the member is positioned in an absorbent article. In particular, capillary suction capacity is measured in terms of a member's capillary sorption absorbent capacity, which is measured in accordance with the Capillary Sorption method described in the Test Methods section.Type: GrantFiled: March 1, 1999Date of Patent: April 16, 2002Assignee: The Procter & Gamble CompanyInventors: Gerald A. Young, Thomas A. Desmarais, Gianfranco Palumbo, Mattias Schmidt, Stephen A. Goldman, Arman Ashraf, James C. Horney

Patent number: 5632737Abstract: Absorbent foams materials that are capable of acquiring and distributing aqueous fluids, especially discharged body fluids such as urine. These absorbent foams combine relatively high capillary absorption pressures and capacity-per-weight properties that allow them to acquire fluid, with or without the aid of gravity. These absorbent foams also give up this fluid efficiently to higher absorption pressure storage materials, including foam-based absorbent fluid storage components, without collapsing. These absorbent foams are made by polymerizing high internal phase emulsions (HIPEs).Type: GrantFiled: May 14, 1996Date of Patent: May 27, 1997Assignee: The Procter & Gamble CompanyInventors: Keith J. Stone, Thomas A. DesMarais, Gary D. LaVon, Stephen A. Goldman, Paul Seiden

Patent number: 5599335Abstract: Absorbent members useful in the containment of body fluids such as urine, that have at least one region containing hydrogel-forming absorbent polymer in a concentration of from about 60 to 100% by weight and providing a gel-continuous fluid transportation zone when in a swollen state. This hydrogel-forming absorbent polymer has: (a) a Saline Flow Conductivity (SFC) value of at least about 30.times.10.sup.-7 cm.sup.3 sec/g; (b) a Performance under Pressure (PUP) capacity value of at least about 23 g/g under a confining pressure of 0.7 psi (5 kPa); and (c) a basis weight of at least about 10 gsm. In addition, the region where this hydrogel-forming absorbent polymer is present has, even when subjected to normal use conditions, sufficient wet integrity such that the gel-continuous zone substantially maintains its ability to acquire and transport body fluids through the gel-continuous zone.Type: GrantFiled: March 29, 1994Date of Patent: February 4, 1997Assignee: The Procter & Gamble CompanyInventors: Stephen A. Goldman, Nancy A. Haynes, Todd L. Mansfield, Manfred Plischke, Herbert L. Retzsch, Trevor Walker, Gerald A. Young

Patent number: 5500451Abstract: A process for preparing high internal phase emulsions (HIPE) that can be polymerized to provide flexible, microporous, open-celled polymeric foam materials capable of absorbing aqueous fluids, especially aqueous body fluids such as urine. The HIPE is prepared using certain polyglycerol aliphatic ether emulsifiers that are less chemically complex and variable in composition than many prior HIPE emulsifiers, have higher levels of the desired interfacially active components, and have lower levels of components (e.g., sludge) that are insoluble or insufficiently soluble in the oil phase used to prepare the HIPE. These polyglycerol aliphatic ether emulsifiers provide HIPE having relatively uniform sized water droplets dispersed in the continuous oil phase.Type: GrantFiled: August 9, 1995Date of Patent: March 19, 1996Assignee: The Procter & Gamble CompanyInventors: Stephen A. Goldman, Jeffrey J. Scheibel

Patent number: 5061259Abstract: The present invention relates to absorbent structures and absorbent gelling agent compositions suitable for use in disposable absorbent articles such as diapers, incontinence products and catamenial products. The absorbent structures comprise hydrophilic fiber material and nonfragile particles of polymeric gelling agent. The gelling agent particles incorporated into such structures are selected to have a mass median particle size ranging from about 400 to 700 microns, with the amounts of very large and very small particles kept below certain minimum concentrations. Absorbent structures utilizing gelling agent particles of such particle size characteristics possess unexpectedly high absorbent capacities and the gelling agent therein can be utilized very efficiently and effectively.Type: GrantFiled: November 20, 1990Date of Patent: October 29, 1991Assignee: The Procter & Gamble CompanyInventors: Stephen A. Goldman, James C. Horney, Herbert L. Retzsch

Patent number: 4654039Abstract: The present invention relates to improved hydrogel-forming polymer compositions which can be used as absorbents in absorbent structures and absorbent articles such as diapers, sanitary napkins and the like. Such hydrogel-forming polymer compositions are substantially water-insoluble, slightly cross-linked, partially neutralized polymers which are prepared from unsaturated polymerizable, acid group-containing monomers and cross-linking agents. These hydrogel-forming polymer materials, upon imbibing fluids, form hydrogels. Such polymer materials have relatively high gel volume and relatively high gel strength as measured by shear modulus of the hydrogel which forms therefrom. Such polymer materials also contain relatively low levels of extractable polymer material which can be extracted therefrom by contact with synthetic urine.Type: GrantFiled: June 18, 1985Date of Patent: March 31, 1987Assignee: The Proctor & Gamble CompanyInventors: Kerryn A. Brandt, Stephen A. Goldman, Thomas A. Inglin
