Patent number: 8969652Abstract: A sanitary napkin is disclosed as a form of disposable absorbent article. It has an absorbent core and a hydrophobic topsheet that has an upper side that is to be worn against a user's body. The topsheet is selected from a group of nonwoven topsheets and apertured film topsheets. A trace amount of a fibrous superabsorbent material, in the range of 0.30 and 3.5 grams of superabsorbent material per square meter, is provided in a fibrous matrix in a secondary topsheet that is in intimate contact with the lower side of the topsheet. The fibrous matrix is made by airlaying the superabsorbent material with cellulose and bi-component fiber onto a non-woven carrier.Type: GrantFiled: September 19, 2011Date of Patent: March 3, 2015Assignee: The Procter & Gamble CompanyInventors: Christopher Philip Bewick-Sonntag, Ronald Dean Cramer, James A. Hatton

Publication number: 20120237683Abstract: The present invention relates to an absorbent article having a stable skin care composition disposed on its skin-contacting surface. The skin care composition is readily transferable to the skin via normal contact, wearer motion, and/or body heat. Importantly, the skin care composition contains at least one skin care ingredient imparting visible skin benefits to the skin upon transfer to the skin and at least one rheological agent for stabilizing the composition such that agglomeration, stratification and/or settling of the composition are minimized. The present invention also relates to a process for making the absorbent articles having a stable skin care composition disposed thereon.Type: ApplicationFiled: September 19, 2011Publication date: September 20, 2012Inventors: Joseph Anthony Gatto, Thomas Robert Hanser, James Anthony Staudigel, Thomas James Klofta, Ronald Dean Cramer, Donald Carroll Roe

Patent number: 6863933Abstract: Coating compositions, methods and articles of manufacture comprising a nanoparticle system employing same to impart surface modifying benefits for all types of soft surfaces, and in some cases, hard surfaces, are disclosed. In some embodiments, dispersement of nanoparticles in a suitable carrier medium allows for the creation of coating compositions, methods and articles of manufacture that create multi-use benefits to the modified surfaces. These surface modifications can produce long lasting or semi-permanent multi-use benefits that, in some embodiments, may include at least one of the following improved surface properties: cleaning, wettability, liquid strike-through, comfort, stain resistance, soil removal, malodor control, modification of surface friction, reduced damage to abrasion and color enhancement, relative to the surfaces unmodified with such nanoparticle systems.Type: GrantFiled: January 30, 2002Date of Patent: March 8, 2005Assignee: The Procter and Gamble CompanyInventors: Ronald Dean Cramer, Robert Henry Rohrbaugh, John David Carter, Karl Edward Thuemmler, Ekaterina Anatolyevna Ponomarenko, Mattias Schmidt
